Appraising Sustainable Building Features: A Colorado Case Study

Appraising Sustainable Building Features: A Colorado Case Study Appraising Sustainable Building Features: A Colorado Case Study A u t h o r s Laura Bently, Scott Glick, and Kelly Strong A b s t r a c t We investigate the current status of sustainable value integration in Colorado’s real estate markets, an area with limited current / historical value attributed to sustainability. The property appraiser has an opportunistic position to influence stakeholders and potentially increase demand for sustainable building. The appraisal process, necessary inputs, and rules and regulations were studied using an exploratory sequential mixed methods approach to conduct a cross-sectional study through archival research, survey distribution, and the collection of quantitative and qualitative data. We confirm that Colorado’s real estate appraisers are increasingly integrating sustainable building features in appraisal assignments, despite existing challenges. In the United States, buildings account for 41% of primary energy consumed (U.S. Department of Energy, 2011). As a result of energy consumption, buildings contribute 39% of the total carbon dioxide emissions, in addition to other greenhouse gas emissions (Pearce, Hahn Ahn, and HanmiGlobal Co., 2012). It seems only appropriate that since the building sector contributes such a large proportion of these negative environmental impacts, this sector has huge potential to cause change and induce reverse effects through decreasing energy consumption and emissions. This reduction could be achieved through sustainable building and development strategies. Building sustainably remains largely a voluntary action in the building industry worldwide. Despite advances being made by policymakers and government organizations (Pearce, Hahn Ahn, and HanmiGlobal Co., 2012) and overwhelming evidence pointing to the potential benefits sustainable building could offer to its stakeholders, there remains much resistance to the ‘‘green movement’’ in the construction industry (Warren-Myers, 2011). Researchers have produced a thorough list of barriers to sustainable building (Hakkinen and Belloni, 2011; Pearce, Hahn Ahn, and HanmiGlobal Co., 2012; Warren-Myers, 2011), including financial incentives and affordability as the most important driver and barrier, respectively, for sustainable building (Pitt, Tucker, and Longden, 2009). Therefore, the economic values of sustainable building features must be understood, recognized, and accepted by stakeholders to effectively promote sustainable building practices. Some researchers suggest this may be happening, but not to the extent that may be needed to fully integrate the value of sustainable features A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 1 3 into the property valuation process. This study focuses on the current status of appraisal practices in Colorado relative to sustainable building in real property markets to begin to understand the relationship between the construction and real estate industries and their impact on achieving sustainable value integration. This research focus builds on the education and professional practices in real estate and construction realms; therefore, it has the potential to impact all professionals dealing with any aspect of real estate property. A physical building is the end product in these realms and all stakeholders involved in the process of a building’s conception leave some degree of impact on the final product, whether it is a decision made to create the best financial benefit to its investors or a decision on the type of carpet that will be installed. All of these stakeholders also have the opportunity to decide on implementing sustainable building features / practices. This research builds on the importance of understanding barriers and drivers to sustainable building feature integration in order for these industries to be knowledgeable advocates of smarter building practices. In relation to the real estate realm, an analysis of stakeholder relationships found that the appraiser holds a unique position to inform and influence all stakeholder groups (Lorenz, 2008; Warren-Myers, 2013). Property appraisers use their expertise and knowledge to educate stakeholders, including builders, investors, mortgage lenders, insurance providers, and homebuyers on the cost and value of sustainable building features and technologies. Accurate property appraisals have the opportunity to correct misconceptions many consumers have on the cost and return on investment of sustainable building features. In addition, this research will also give the construction realm the opportunity to understand how the appraisal process works in relation to sustainable building features, so that construction-related stakeholders can align their practices with those of the appraisal professionals in order to realize the full potential of sustainable building features during a building’s life cycle. We examine if and where sustainable value integration exists in current real property appraisal practices in Colorado. First, we investigate the nature of sustainable value integration within current appraisal practices in Colorado’s real estate markets. We examine how appraisers obtain information for appraisals and how this translates to collecting information about sustainable building features. Second, we examine the degree of alignment between state mandated criteria for appraiser licensure and their knowledge of sustainable building techniques, materials, and technologies among the current appraiser population. A comparison of state mandated criteria for appraiser licensure and continuing education on sustainability topics reveals areas that are sufficiently or insufficiently meeting the market needs for appraiser competency. Third, we analyze the transparency of the construction industry knowledge of sustainable building techniques, materials, and technologies to the appraisal industry. Fourth, we explore the perceptions of real estate appraisers on the economic implications of sustainable value integration. We also evaluate how appraisers have seen the concept of green building develop. If they see it adding value, and how they see it growing into an everyday practice as real estate markets become more saturated with green building features. J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 1 4 B e n t l y , G l i c k , a n d S t r o n g L i t e r a t u r e R e v i e w Despite the overwhelming evidence of the benefits of sustainable buildings (Pearce, Han, and HanmiGlobal Co., 2012), stakeholders in construction building practices rely on fundamental economics in the business sense, affordability, payback, and financial incentives when deciding to invest in green real estate (Wolff, 2006; Lutzkendorf and Lorenz, 2007; Pitts and Jackson, 2008). Pivo and Fisher (2010) and Kok, McGraw, and Quigley (2011) examine value, income, and returns; they both found that buildings with an ENERGY STAR label, located close to transportation, and sited in redevelopment areas had equal or higher returns than conventional properties, suggesting that responsible real estate investing can be done. However, as pointed out by Prum (2013), lenders may still fail to understand the difference between a loan for a traditional building and one for a building with green features; an issue that could impact the appraisal process. The financial barriers to implementing sustainability in construction were discovered through a review of literature and classified into five categories as follows: property assessment and valuation, initial perceptions of cost, insurance provisions, mortgage lending, and property yield. First, property valuation creates an interdependent relationship with market value. This relationship revolves around two key concepts: (1) the market value of a property is dependent on the value the public perceives those features are worth and (2) property value is dependent on quantitative and qualitative values reported by the property appraiser. Second, initial perceptions of cost make it evident that there is a need to inform the public and educate appraisers about the social, environmental and economic benefits of sustainable design and construction (Bartlett and Howard, 2000; Lutzkendorf and Lorenz, 2005; Pitts and Jackson, 2008; Leopoldsberger et al., 2011; Lorenz and Lutzkendorf, 2011). However, previous research has presented conflicting statements on the initial costs of building with green features, so it is no wonder the general public is not confident in making these investments systematically. Third, circumstances surrounding insurance companies and the insurability of a sustainable project are also affected by property appraisal techniques. Pricing for conventional and green buildings depends on the associated risks. Once building characteristics and performance criteria are implemented in appraisal strategies, insurance companies can begin to develop their risk analyses based on these performance criteria assessments (Mills, 2003; Bakens, Foliente, and Jasuja, 2005; Lutzkendorf and Lorenz, 2005; Lorenz, Truck, and Lutzkendorf, 2006). Fourth, mortgage lenders and their perception of sustainable buildings are also affected by property appraisal techniques and risk assessment. Interest rates and approval of property loans are determined in direct relation to the associated risks, along with the consideration of the borrower’s ability to make payments and the price stability of the collateralized property. Arguably, since sustainable properties have been shown to increase marketability and provide a stable income stream, A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 1 5 Exhibit 1 u The Vicious Circle of Blame The source is Cadman (2000). this is a real insight to the credibility and financial benefits of sustainable over conventional buildings (Lutzkendorf and Lorenz, 2005). Finally, future rental and lease rates are another decisive factor that an investor will examine, in addition to the resale value relative to the local market (National Real Estate Investor, 2013). Pitts and Jackson (2008) believe that green buildings are leasing at above normal market rates with lower tenant turnover. However, research on this topic is still very scarce due to a lack of information in real estate databases and understanding of how to assess the relations between building characteristics and rental or lease rates. Cadman (2000) contributed a fundamental principle in understanding the dynamic relationships between stakeholders: the ‘‘vicious circle of blame’’ (Exhibit 1). Through an examination of the relationships that exist between occupiers, constructors, developers, and investors, it was determined that the adoption of sustainability in the real estate market will be limited as long as the ‘‘blame’’ of not promoting a sustainable building is passed from one stakeholder to the next in this ‘‘vicious circle.’’ With the consideration of the five categories of financial barriers previously mentioned, it was determined that insurance providers, mortgage lenders, and appraisers also have a stake in the adoption of sustainability. Lorenz (2008) contributes his contradiction of the ‘‘vicious circle of blame’’ with the inclusion of researchers, educators, policymakers, and owner associations in addition to the aforementioned stakeholder groups. Prior research analyzing relationships among all key stakeholders and their roles in sustainable building has shown that the appraiser holds a unique position to inform and influence all stakeholder groups (Lorenz, 2008; Warren-Myers, 2011). J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 1 6 B e n t l y , G l i c k , a n d S t r o n g Exhibit 2 u Exploratory Sequential Mixed Methods Process The source is Creswell (2014). Increasing investment and demand in sustainable building practices is the common goal within the literature (Pitt, Tucker, and Longden, 2009; Warren-Myers, 2011). However, there is a need for further clarification and exploration in order to overcome barriers and achieve integration of the value associated with sustainable building features in real estate markets. We begin to fulfill the need for empirical data by collecting information from practicing appraisal professionals in Colorado’s real estate markets regarding their current appraisal practices. By discovering where the integration of sustainability value exists in current real estate appraisal in Colorado, a baseline will be created for future research to expand our understanding of the link between property valuation and sustainable design and construction. M e t h o d o l o g y In this mixed methods study, we addressed the status of appraisal practices relative to sustainable value integration in real estate markets in Colorado. This cross- sectional study collected data through archival research that pertained to current appraisal practices and collected survey data from current, licensed appraisers in Colorado. A mixed methods approach was used to collect quantitative and qualitative data. This method offered several advantages to this study. One data set had the potential to explain the other, collecting two sets of data would provide a validity test to the research, and collecting qualitative data offered the opportunity for a much richer examination of the phenomenon being studied (Creswell, 2014). More importantly, the origins of this research approach from Campbell and Fiske (1959) suggest that mixing quantitative and qualitative methods helps ensure any resulting variance within the data sets reflect the relationship being studied instead of constraints inherent in a specific research method (Creswell, 2014). The commonly-used term for the benefits of mixed methods research is ‘‘triangulation’’ (Denzin, 1978). In the exploratory sequential mixed methods approach there were two phases of data collection (Exhibit 2). In the first phase, we conducted archival research to investigate qualitative information related to mandated laws and regulations for appraisal in Colorado. We identified methodologies and tools suggested by industry organizations and related research available to appraisers for sustainable value integration. By comparing these two initial investigations, an understanding of the sustainable knowledge gap between mandated appraisal practice and opportunities to understand and integrate information related to sustainable A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 1 7 building features and technologies began to appear. We used the data collected in this first phase to develop the content in the survey measurement instrument for the second phase of data collection. In the second phase of data collection, we distributed the survey to 322 appraisers, using Qualtrics, to collect primarily quantitative information related to awareness of sustainable value integration, types of features they have experience appraising, and if they believe sustainable building features have an economic impact to building appraisal. A list of questions used in the survey is shown in the Appendix. Due to the small number of respondents (45), the conclusions drawn from the data may not be generalizable to the entire appraiser population, but they do represent a beginning to understanding the challenges behind the nature of sustainable value integration practices. D a t a A n a l y s i s The survey was distributed to 322 licensed and active appraisers in Colorado determined from the National Registry and the Appraisal Institute (AI) Member Registry. Forty-five surveys were returned for a response rate of 14%. The overall goal of this research was to discover the current status of sustainable value integration in appraisal practices in Colorado. Simply stated, are appraisers recognizing and including sustainable building features in their appraisal assignments? Therefore, the survey questions were designed to accommodate the appraisers who fit into the two potential responses to this question: (1) those who were aware of sustainable value integration in property appraisal (Group 1, n 5 38) and (2) those who were not aware of sustainable value integration in property appraisal (Group 2, n 5 7). In addition to questions that were relevant to both responses, specialized questions were also developed to explore the opportunities to collect data and information from both groups. Summary of Group 1 Analysis The categories of property types most often appraised by the respondents include: commercial, 53%; residential, 34%; industrial, 5%; and other, 8%. The analysis of Group 1 data revealed telling information about the current status of appraisal practices in Colorado relative to sustainable building features and current challenges that appraisers are facing in fully integrating them. First, we found that 84% of respondents are aware of sustainable valuation methods and practices (Exhibit 3). Major features currently being considered were discovered (Exhibit 4), however, uncertainty as to the extent of appraiser knowledge about sustainable building features and technologies and the degree to which sustainable features are carried through the appraisal process remains. Second, we found that 82% of respondents had appraised real property in which sustainable features were considered (Exhibit 5). The majority of appraisers began to notice sustainable building features being incorporated into appraisal processes J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 1 8 B e n t l y , G l i c k , a n d S t r o n g Exhibit 3 u Awareness of Appraisal Methods and Practices Are you aware of appraisal methods and practices to valuate sustainable Q3 building features that are implemented in real property today? # Answer Responses % 1 Yes 38 84% 2 No 7 16% Total 100% Note: The number of observations is 45.

Considering the different inputs of the sales comparison, income, and cost approaches, some approaches are more likely to include sustainable factors than others. However, appraisers are challenged in obtaining credible information to support input attributes used in the appraisal method chosen. There is risk in uncertainty for appraisers. Therefore, to avoid this risk, appraisers prefer to rely on verifiable, third-party information to base their assumptions and conclusions for final appraisal value. Again, the appraiser needs to validate the content and source of information to be confident that it is factual, even though provided by a third party. These respondents also concluded that there are insufficient tools and information sources available to appraisers relating to sustainable features (Exhibit 8). The majority of these factors impact the appraiser’s ability to measure and quantify features that influence a property’s appraised value.

First, these respondents confirmed there are appraisers currently practicing in the industry that lack knowledge and experience of how to consider sustainable features in an appraisal. However, after being given a list of examples of sustainable building features, it was discovered that some of the appraisers were able to say that several of these features were considered in appraisal J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 2 2 B e n t l y , G l i c k , a n d S t r o n g Exhibit 11 u Group 2 Experience with Sustainable Building Features in Appraisal Assignments Have you been assigned to appraise real property in which any of the sustainable building features listed above could be incorporated into the Q16 valuation process? # Answer Responses % 1 Yes 4 57% 2 No 3 43% Total Total 100% Note: The number of observations is 7. Exhibit 12 u Appraiser Satisfaction to Recognize Sustainable Building Features assignments (Exhibit 11). The idea that an insufficient definition of sustainability concepts and elements coupled with educational deficiencies challenges stakeholders in progressing toward sustainable value integration as a standard is supported by further data analysis. Second, overall respondents were not satisfied in their ability to recognize sustainable features (Exhibit 12). Those features rated with higher satisfaction were features that were similar to elements in traditional buildings. The challenge here lies in how to measure and quantify their impacts. The respondents also rated their ability to value the same features between good and poor (Exhibit 13). Again, without information to quantify their impacts, appraisers cannot apply these measurements and data to appraisal methods. Finally, availability of accurate information and data was a need expressed by all respondents in this group, specifically data related to economic costs and benefits, A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 3 Exhibit 13 u Appraiser Ability to Valuate Sustainable Building Features Exhibit 14 u Information and Tools Desired by Group 2 comparable sales, property transactions, and MLS databases (Exhibit 14). In general, respondents are aware of additional opportunities for continuing education and professional development (Exhibit 15); however, these opportunities are not mandatory and not always available to those who face financial and / or location related challenges. Several dominant themes were discovered in the data analysis process to help explain current appraisal practices and the challenges appraisers face when trying to integrate sustainable features into the process. These overarching themes of information collected from Group 1 and Group 2 present an understanding of the barriers to achieving sustainable value integration facing the real estate and building industries.

D a t a A n a l y s i s a n d D i s c u s s i o n The results suggest that a meeting of the minds could be achieved by discovering what each stakeholder group already knows and what they have yet to discover. Targeting this bigger picture, the results may affect thinking on education, federal and state laws and regulations, methodologies, and industries practices relative to sustainable building features / practices. We find that the current status of sustainable value integration in Colorado is progressing, with sustainable building features increasingly recognized and considered in appraisal assignments by 82% of survey participants (Exhibit 5). Respondents confirmed that all building attributes, sustainable and otherwise, should be included in the appraisal process; however, some remain unsure and inconclusive of market interaction due to limited information and data, or their lack of experience or knowledge (Exhibit 7). While the majority of the respondents who have experience appraising sustainable features noted seeing sustainable value integration within the last seven years (Exhibit 6), there remain several dominant challenges facing appraisers and stakeholders within the sustainable value integration process. These challenges are summarized below. First, sustainable feature recognition remains a challenge for a portion of the appraiser population. It was discovered that not all appraisers are able to recognize and therefore, consider sustainable building features for the final appraisal value (Exhibit 3). While the definition of sustainability remains ambiguous and broad, appraisers must decipher the impacts of individual sustainable features as well as those features that create systems within a building to achieve broader sustainability concepts. However, unless appraisers are given specific information about a property’s sustainable features, they are more likely to incorporate those that are visible over those that are not. Despite these challenges, sustainable A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 5 Exhibit 16 u Format Followed by Appraisers for Appraisal Process Q2 What format do you follow in the appraisal process?

Within the standard property appraisal process established by the Uniform Standards of Professional Appraisal Practice (USPAP), an appraiser must examine the subject property and gather all information on the property’s market area, physical characteristics, and market data on comparable properties. Therefore, it will be important to the future success of sustainable value integration in the industry to include sustainability as a topic in the standard curriculum of appraiser education. Second, we found that even though respondents are able to recognize sustainable building features, they are continually challenged by the inability to measure and quantify their economic impacts. Property is a heterogeneous product that exists in constantly evolving real estate markets. Because of this, respondents revealed that they were unsure of how to develop a standardized system to measure sustainable building features. We showed that the data inputs relative to the sustainable features being recognized by appraisers now (Exhibit 16) fit into the current appraisal process described for conventional building attributes. Currently, economic cost and benefits such as return on investment, rent premiums, and utility savings are the primary focus of appraisers’ investigation. Appraisers rely on measureable, verifiable data to create an accurate opinion of market value. Information obtained from energy modeling, performance ratings, and utility bills for those buildings with sustainable features are recommended sources to provide this documented data for appraisers. If this information is not available, the appraiser must find other methods of calculating or obtaining this information, but these processes are not yet standardized. Also, the industry has not yet defined a process to recognize those intangible benefits of sustainable building features, like healthier indoor air quality and higher occupant satisfaction. The standard appraisal process dictates that appraisers collect the property data J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 2 6 B e n t l y , G l i c k , a n d S t r o n g and then perform their analysis according to an appraisal approach. Therefore, in order to consider the impact that sustainable building features have on property value, the benefits of the features first need to be measured and quantified. Without this data, appraisers cannot conduct a thorough comparative analysis. Third, we found that respondents are challenged by a lack of information and data related to sustainable building features. When examining the subject property, respondents noted that they do not get enough information from the builder or owner up front regarding any sustainable features that have been implemented in the property. What we were not able to determine is when sufficient data fails to be documented, are building features simply excluded from the appraisal? If so, how does this exclusion translate to those stakeholders who are trying to promote sustainable building practices? Product specifications provided to the appraiser by the builder or owner would provide relevant information to conduct research on the products’ performance capabilities and thus to estimate an economic value. We found that 74% of respondents who have appraised property with sustainable features require documentation to validate the appraisal (Exhibit 9). Research confirms that uncertainty creates risk for the appraiser. Therefore, reliable, documented information is preferred to reach an accurate estimation of value. Appraisers expressed a need for updated, searchable databases including MLS listings, comparable sales, property transactions, and market data to determine if these features are recognized by the market. This information is crucial to reaching a conclusive opinion of property value. If a reliable property database is not designed, implemented, and maintained, we may see a perpetual exclusion of sustainable features going forward. After the data analysis has been conducted on property features, the appraiser must report the results, according to the USPAP standards. Sufficient information and data need to be available for appraisers to use as a comparison to other values in real estate markets. Using this information, the appraiser will determine which property features the market has recognized. Their report will include the property and market data and adjustments made to value, along with justification for those adjustments. These appraisal reports build on existing property and market data and support future property transactions. To achieve sustainable value integration in all appraisal practices in Colorado, these three major challenges need to be addressed and mitigated. It will be important for appraisal professionals to gain a fluent understanding of sustainable building methods, materials, and technologies through standardized curriculum to recognize and incorporate the value created by sustainable features into their appraisal assignments. The continuing education of appraisers will also play a role as building practices continue to evolve. The development of processes and methods to measure and quantify impacts will be crucial to incorporating value associated with sustainable building features in the appraisal process. R e s e a r c h A i m s R e v i s i t e d The purpose of this research was to discover the current status of sustainable value integration and form an understanding of the processes and challenges facing A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 7 appraisers today in Colorado’s real estate markets. First, we were successful in investigating the nature of sustainable value integration within current appraisal practices in Colorado’s real estate markets. We summarized pertinent terms and provided definitions to create parameters. Next, qualification criteria and the process to obtain appraisal licensure were discussed. Then, research on the governing authority for appraisal standards and practices, laws and regulations, and the typical, step-by-step appraisal process was explained. This information provided much of the demographic information for the study pertaining to the participants. We were able to determine that all active appraisers in the state of Colorado had to have a valid appraisal license. This section also created the baseline for comparison of sustainable value integration practices and regulations against the information collected in objective two. Second, we identified the degree of alignment between state mandated criteria for appraiser licensure and appraiser knowledge of sustainable building techniques, materials, and technologies. Mandated curriculum for initial licensure and continuing education requirements were summarized for the general property appraiser certification as stipulated by USPAP and the state of Colorado. Educational opportunities targeting sustainability topics were not present in the initial curriculum, but were offered in continuing education opportunities. Then, we investigated primary resources for sustainable building information and data provided by professional organizations. Finally, by comparing the mandated appraisal processes to the education and resources available on sustainable building features, we determined that there is a deficiency in the expectations of the appraisal process and the qualification and education requirements of those who are able to appraise. Third, we analyzed the transparency of construction industry knowledge in relation to sustainable building techniques, materials, and technologies compared to the appraisal industry. We utilized information discovered in previous objectives to develop a survey targeting two groups of appraisers: (1) those with experience appraising properties with sustainable building features, and (2) those without experience appraising sustainable building features. We assembled contact information for 322 active licensed appraisers in Colorado using the National Appraiser Registry and the AI Member Registry. Fourth, we explored perceptions of real estate appraisers on the economic implications of sustainable value integration. We were successful in identifying and reporting on the respondents who were aware and unaware of sustainable value integration methods and practices. Those sustainable building features that were being considered and those that appraisers felt should be considered were included in the study. Survey respondent perceptions on those features that add value to a property and the challenges to realizing their potential for impact were also revealed. We conclude that there are three challenges to achieving sustainable value integration in Colorado’s property markets: (1) sustainable feature recognition; (2) ability to measure and quantify economic impacts; and (3) the availability of information and data. J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 2 8 B e n t l y , G l i c k , a n d S t r o n g Limitations of the Study One limitation to the data collected in the study lies in the lack of a uniform definition for the term ‘‘sustainable.’’ Often the term ‘‘sustainability,’’ ‘‘green,’’ and ‘‘energy efficient’’ are used interchangeably in discussions about the same concepts. These phrases may have different meanings dependent on their context and theory of application. Another limitation to the study lies in the types of sustainable building features that were defined for the survey participants. Due to the ambiguity of ‘‘sustainability,’’ ‘‘green,’’ and ‘‘energy efficient,’’ we developed a list of sustainable features to reference in survey questions and responses. The list included site orientation, building envelope quality, HVAC, building performance energy rating, insulation, renewable energies (solar panels, wind), lighting controls, appliances / equipment selection, water efficiency, proximity to community and public transportation, indoor air quality, utility cost (electric, water, wastewater, stormwater), and daylighting. However, this list presents several issues for the study. First, it is comprised of both sustainable building features and sustainable building concepts. Many of these terms could still be considered broad and ambiguous to the respondents. For example, when considering water efficiency, this term could be referring to low-flow plumbing fixtures, gray water systems, xeriscaping, etc. Second, it is difficult to differentiate between a single building feature like insulation and an entire concept like energy efficiency. It is also difficult to define what benefits appraisers need to be aware of and capable of calculating. Is the benefit being seen from the type of insulation, or is the benefit being seen in a better building envelope and therefore lower energy use? Thus, it is difficult to determine which features and / or concepts are good proxies to measure survey inquiries. A third limitation is created by the heterogeneous nature of property and the types of interest they hold. We examined the typical property appraisal process as mandated by the USPAP and the three primary appraisal approaches. We did not consider the nature of sustainable value integration relative to appraisal practices covering specific types of rights and interests relative to the subject property. Also, we acknowledge that appraisers are often held to include certain criteria for the appraisal by their employers. Rules and regulations pertaining to required criteria and their extents for all property appraisals were beyond the scope of this study. A fourth limitation lies in the archival research conducted to discover where education related to sustainability and building practices was present in mandated curriculum for initial licensure and continuing education requirements for appraisers. One limitation to the evaluation of the initial curriculum required for licensure is that we did not review every course outline for content related to sustainability. USPAP defines the topics needed to meet their curriculum requirements; however, they do not develop the specific outlines or lesson plans for each class. Therefore, there are many sources to get a real estate appraisal education. We determined that a review of every class offered was unrealistic. It A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 9 is possible that issues related to sustainable building features are discussed and applied within other curriculum topics. Finally, the survey population also limits the study. Those members who are listed on the National Registry are active and licensed appraisers and those listed in the AI Member Registry are also active and licensed, but have a vested interest in being more experienced and knowledgeable of appraisal issues and trends. These AI members have also taken the initiative to earn an additional AI designation, which means they have additional education above and beyond the requirements of USPAP. Therefore, the appraisal population selected for this survey may have been slightly in favor of the study because of their additional experience and education. Overall, there was still a portion of the survey population that was not aware of and did not have experience with sustainable value integration practices in appraisal. C o n c l u s i o n The literature review proposed several needs for further investigation into opportunities to mitigate challenges facing stakeholders investing in sustainable building practices / systems. Previous research expressed a need for further research to provide clarification on several fronts in order to achieve sustainable value integration in real estate appraisal. First, education and continuing education requirements need to adopt sustainability into their curriculum. We found that all appraisers are not able to recognize and value sustainable building features. Mandated education does not have a specific focus on sustainable building concepts and features. Continuing education opportunities related to sustainability are available, but not mandatory. The incorporation of education specifically focused on issues related to understanding, integrating, and reporting on sustainable building features needs to be seriously considered by governing authorities in order to mitigate this deficiency in appraiser knowledge. Second, the need for a standardized measurement system to assess qualitative and quantitative benefits of sustainable building features and their economic impacts to real estate property has been expressed by other researchers. Our results also confirmed this need. Appraisal approaches are based on quantitative inputs and mathematical formulas. Survey respondents were found to be unsure of how to measure certain tangible and intangible benefits resulting from both visible and not visible building features. These respondents expressed a need for a method to measure and quantify the various economic impacts of sustainable building features and a standardized method to input these figures into an analysis. Third, researchers have suggested that property transaction databases be created and / or re-furbished to enable comparative studies of properties with sustainable building features. Again, our findings confirmed that this type of information is necessary and crucial to the success of appraisers in being able to collect data and report on market value. Respondent to our survey expressed a need for a new type J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 3 0 B e n t l y , G l i c k , a n d S t r o n g of searchable database or updating of existing databases to include sustainable building features. However, it is up the appraisers and other real estate professionals to investigate each property and include this information in these databases. Fourth, due to the small sample size, several things could be done in future research to confirm and strengthen this study. First, a survey of the non- respondents could be done to help confirm whether the results are representative of a larger population. Second, additional questions could be added to the survey to measure the impact of LEED certification and ENERGY STAR ratings on appraisal practices. It may also be helpful to further distinguish the types of commercial property that are appraised to ascertain if the properties are ‘‘high profile’’ where sustainable features are well known and advertised when leasing or selling. Finally, our goal was to contribute to the limited empirical data available on what is taking place in the property appraisal industry relative to sustainability, rather than proposing additional suppositions as previous researchers have done. We discovered, from a small population sample of Colorado appraisers, how many appraisers were considering sustainable building features in appraisal assignments. Sustainable building features being recognized by appraisers were found, but their impact on final appraisal value was not. In general, the features being considered are those that are currently quantifiable. From those features, it was revealed they are not being recognized by all markets, and therefore not impacting final appraisal value. We conclude that it will be necessary to mitigate existing challenges and fulfill research and development needs in order for the building and real estate industries to realize the full potential of sustainability and its impact on property value.

Abstract

Appraising Sustainable Building Features: A Colorado Case Study A u t h o r s Laura Bently, Scott Glick, and Kelly Strong A b s t r a c t We investigate the current status of sustainable value integration in Colorado’s real estate markets, an area with limited current / historical value attributed to sustainability. The property appraiser has an opportunistic position to influence stakeholders and potentially increase demand for sustainable building. The appraisal process, necessary inputs, and rules and regulations were studied using an exploratory sequential mixed methods approach to conduct a cross-sectional study through archival research, survey distribution, and the collection of quantitative and qualitative data. We confirm that Colorado’s real estate appraisers are increasingly integrating sustainable building features in appraisal assignments, despite existing challenges. In the United States, buildings account for 41% of primary energy consumed (U.S. Department of Energy, 2011). As a result of energy consumption, buildings contribute 39% of the total carbon dioxide emissions, in addition to other greenhouse gas emissions (Pearce, Hahn Ahn, and HanmiGlobal Co., 2012). It seems only appropriate that since the building sector contributes such a large proportion of these negative environmental impacts, this sector has huge potential to cause change and induce reverse effects through decreasing energy consumption and emissions. This reduction could be achieved through sustainable building and development strategies. Building sustainably remains largely a voluntary action in the building industry worldwide. Despite advances being made by policymakers and government organizations (Pearce, Hahn Ahn, and HanmiGlobal Co., 2012) and overwhelming evidence pointing to the potential benefits sustainable building could offer to its stakeholders, there remains much resistance to the ‘‘green movement’’ in the construction industry (Warren-Myers, 2011). Researchers have produced a thorough list of barriers to sustainable building (Hakkinen and Belloni, 2011; Pearce, Hahn Ahn, and HanmiGlobal Co., 2012; Warren-Myers, 2011), including financial incentives and affordability as the most important driver and barrier, respectively, for sustainable building (Pitt, Tucker, and Longden, 2009). Therefore, the economic values of sustainable building features must be understood, recognized, and accepted by stakeholders to effectively promote sustainable building practices. Some researchers suggest this may be happening, but not to the extent that may be needed to fully integrate the value of sustainable features A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 1 3 into the property valuation process. This study focuses on the current status of appraisal practices in Colorado relative to sustainable building in real property markets to begin to understand the relationship between the construction and real estate industries and their impact on achieving sustainable value integration. This research focus builds on the education and professional practices in real estate and construction realms; therefore, it has the potential to impact all professionals dealing with any aspect of real estate property. A physical building is the end product in these realms and all stakeholders involved in the process of a building’s conception leave some degree of impact on the final product, whether it is a decision made to create the best financial benefit to its investors or a decision on the type of carpet that will be installed. All of these stakeholders also have the opportunity to decide on implementing sustainable building features / practices. This research builds on the importance of understanding barriers and drivers to sustainable building feature integration in order for these industries to be knowledgeable advocates of smarter building practices. In relation to the real estate realm, an analysis of stakeholder relationships found that the appraiser holds a unique position to inform and influence all stakeholder groups (Lorenz, 2008; Warren-Myers, 2013). Property appraisers use their expertise and knowledge to educate stakeholders, including builders, investors, mortgage lenders, insurance providers, and homebuyers on the cost and value of sustainable building features and technologies. Accurate property appraisals have the opportunity to correct misconceptions many consumers have on the cost and return on investment of sustainable building features. In addition, this research will also give the construction realm the opportunity to understand how the appraisal process works in relation to sustainable building features, so that construction-related stakeholders can align their practices with those of the appraisal professionals in order to realize the full potential of sustainable building features during a building’s life cycle. We examine if and where sustainable value integration exists in current real property appraisal practices in Colorado. First, we investigate the nature of sustainable value integration within current appraisal practices in Colorado’s real estate markets. We examine how appraisers obtain information for appraisals and how this translates to collecting information about sustainable building features. Second, we examine the degree of alignment between state mandated criteria for appraiser licensure and their knowledge of sustainable building techniques, materials, and technologies among the current appraiser population. A comparison of state mandated criteria for appraiser licensure and continuing education on sustainability topics reveals areas that are sufficiently or insufficiently meeting the market needs for appraiser competency. Third, we analyze the transparency of the construction industry knowledge of sustainable building techniques, materials, and technologies to the appraisal industry. Fourth, we explore the perceptions of real estate appraisers on the economic implications of sustainable value integration. We also evaluate how appraisers have seen the concept of green building develop. If they see it adding value, and how they see it growing into an everyday practice as real estate markets become more saturated with green building features. J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 1 4 B e n t l y , G l i c k , a n d S t r o n g L i t e r a t u r e R e v i e w Despite the overwhelming evidence of the benefits of sustainable buildings (Pearce, Han, and HanmiGlobal Co., 2012), stakeholders in construction building practices rely on fundamental economics in the business sense, affordability, payback, and financial incentives when deciding to invest in green real estate (Wolff, 2006; Lutzkendorf and Lorenz, 2007; Pitts and Jackson, 2008). Pivo and Fisher (2010) and Kok, McGraw, and Quigley (2011) examine value, income, and returns; they both found that buildings with an ENERGY STAR label, located close to transportation, and sited in redevelopment areas had equal or higher returns than conventional properties, suggesting that responsible real estate investing can be done. However, as pointed out by Prum (2013), lenders may still fail to understand the difference between a loan for a traditional building and one for a building with green features; an issue that could impact the appraisal process. The financial barriers to implementing sustainability in construction were discovered through a review of literature and classified into five categories as follows: property assessment and valuation, initial perceptions of cost, insurance provisions, mortgage lending, and property yield. First, property valuation creates an interdependent relationship with market value. This relationship revolves around two key concepts: (1) the market value of a property is dependent on the value the public perceives those features are worth and (2) property value is dependent on quantitative and qualitative values reported by the property appraiser. Second, initial perceptions of cost make it evident that there is a need to inform the public and educate appraisers about the social, environmental and economic benefits of sustainable design and construction (Bartlett and Howard, 2000; Lutzkendorf and Lorenz, 2005; Pitts and Jackson, 2008; Leopoldsberger et al., 2011; Lorenz and Lutzkendorf, 2011). However, previous research has presented conflicting statements on the initial costs of building with green features, so it is no wonder the general public is not confident in making these investments systematically. Third, circumstances surrounding insurance companies and the insurability of a sustainable project are also affected by property appraisal techniques. Pricing for conventional and green buildings depends on the associated risks. Once building characteristics and performance criteria are implemented in appraisal strategies, insurance companies can begin to develop their risk analyses based on these performance criteria assessments (Mills, 2003; Bakens, Foliente, and Jasuja, 2005; Lutzkendorf and Lorenz, 2005; Lorenz, Truck, and Lutzkendorf, 2006). Fourth, mortgage lenders and their perception of sustainable buildings are also affected by property appraisal techniques and risk assessment. Interest rates and approval of property loans are determined in direct relation to the associated risks, along with the consideration of the borrower’s ability to make payments and the price stability of the collateralized property. Arguably, since sustainable properties have been shown to increase marketability and provide a stable income stream, A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 1 5 Exhibit 1 u The Vicious Circle of Blame The source is Cadman (2000). this is a real insight to the credibility and financial benefits of sustainable over conventional buildings (Lutzkendorf and Lorenz, 2005). Finally, future rental and lease rates are another decisive factor that an investor will examine, in addition to the resale value relative to the local market (National Real Estate Investor, 2013). Pitts and Jackson (2008) believe that green buildings are leasing at above normal market rates with lower tenant turnover. However, research on this topic is still very scarce due to a lack of information in real estate databases and understanding of how to assess the relations between building characteristics and rental or lease rates. Cadman (2000) contributed a fundamental principle in understanding the dynamic relationships between stakeholders: the ‘‘vicious circle of blame’’ (Exhibit 1). Through an examination of the relationships that exist between occupiers, constructors, developers, and investors, it was determined that the adoption of sustainability in the real estate market will be limited as long as the ‘‘blame’’ of not promoting a sustainable building is passed from one stakeholder to the next in this ‘‘vicious circle.’’ With the consideration of the five categories of financial barriers previously mentioned, it was determined that insurance providers, mortgage lenders, and appraisers also have a stake in the adoption of sustainability. Lorenz (2008) contributes his contradiction of the ‘‘vicious circle of blame’’ with the inclusion of researchers, educators, policymakers, and owner associations in addition to the aforementioned stakeholder groups. Prior research analyzing relationships among all key stakeholders and their roles in sustainable building has shown that the appraiser holds a unique position to inform and influence all stakeholder groups (Lorenz, 2008; Warren-Myers, 2011). J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 1 6 B e n t l y , G l i c k , a n d S t r o n g Exhibit 2 u Exploratory Sequential Mixed Methods Process The source is Creswell (2014). Increasing investment and demand in sustainable building practices is the common goal within the literature (Pitt, Tucker, and Longden, 2009; Warren-Myers, 2011). However, there is a need for further clarification and exploration in order to overcome barriers and achieve integration of the value associated with sustainable building features in real estate markets. We begin to fulfill the need for empirical data by collecting information from practicing appraisal professionals in Colorado’s real estate markets regarding their current appraisal practices. By discovering where the integration of sustainability value exists in current real estate appraisal in Colorado, a baseline will be created for future research to expand our understanding of the link between property valuation and sustainable design and construction. M e t h o d o l o g y In this mixed methods study, we addressed the status of appraisal practices relative to sustainable value integration in real estate markets in Colorado. This cross- sectional study collected data through archival research that pertained to current appraisal practices and collected survey data from current, licensed appraisers in Colorado. A mixed methods approach was used to collect quantitative and qualitative data. This method offered several advantages to this study. One data set had the potential to explain the other, collecting two sets of data would provide a validity test to the research, and collecting qualitative data offered the opportunity for a much richer examination of the phenomenon being studied (Creswell, 2014). More importantly, the origins of this research approach from Campbell and Fiske (1959) suggest that mixing quantitative and qualitative methods helps ensure any resulting variance within the data sets reflect the relationship being studied instead of constraints inherent in a specific research method (Creswell, 2014). The commonly-used term for the benefits of mixed methods research is ‘‘triangulation’’ (Denzin, 1978). In the exploratory sequential mixed methods approach there were two phases of data collection (Exhibit 2). In the first phase, we conducted archival research to investigate qualitative information related to mandated laws and regulations for appraisal in Colorado. We identified methodologies and tools suggested by industry organizations and related research available to appraisers for sustainable value integration. By comparing these two initial investigations, an understanding of the sustainable knowledge gap between mandated appraisal practice and opportunities to understand and integrate information related to sustainable A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 1 7 building features and technologies began to appear. We used the data collected in this first phase to develop the content in the survey measurement instrument for the second phase of data collection. In the second phase of data collection, we distributed the survey to 322 appraisers, using Qualtrics, to collect primarily quantitative information related to awareness of sustainable value integration, types of features they have experience appraising, and if they believe sustainable building features have an economic impact to building appraisal. A list of questions used in the survey is shown in the Appendix. Due to the small number of respondents (45), the conclusions drawn from the data may not be generalizable to the entire appraiser population, but they do represent a beginning to understanding the challenges behind the nature of sustainable value integration practices. D a t a A n a l y s i s The survey was distributed to 322 licensed and active appraisers in Colorado determined from the National Registry and the Appraisal Institute (AI) Member Registry. Forty-five surveys were returned for a response rate of 14%. The overall goal of this research was to discover the current status of sustainable value integration in appraisal practices in Colorado. Simply stated, are appraisers recognizing and including sustainable building features in their appraisal assignments? Therefore, the survey questions were designed to accommodate the appraisers who fit into the two potential responses to this question: (1) those who were aware of sustainable value integration in property appraisal (Group 1, n 5 38) and (2) those who were not aware of sustainable value integration in property appraisal (Group 2, n 5 7). In addition to questions that were relevant to both responses, specialized questions were also developed to explore the opportunities to collect data and information from both groups. Summary of Group 1 Analysis The categories of property types most often appraised by the respondents include: commercial, 53%; residential, 34%; industrial, 5%; and other, 8%. The analysis of Group 1 data revealed telling information about the current status of appraisal practices in Colorado relative to sustainable building features and current challenges that appraisers are facing in fully integrating them. First, we found that 84% of respondents are aware of sustainable valuation methods and practices (Exhibit 3). Major features currently being considered were discovered (Exhibit 4), however, uncertainty as to the extent of appraiser knowledge about sustainable building features and technologies and the degree to which sustainable features are carried through the appraisal process remains. Second, we found that 82% of respondents had appraised real property in which sustainable features were considered (Exhibit 5). The majority of appraisers began to notice sustainable building features being incorporated into appraisal processes J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 1 8 B e n t l y , G l i c k , a n d S t r o n g Exhibit 3 u Awareness of Appraisal Methods and Practices Are you aware of appraisal methods and practices to valuate sustainable Q3 building features that are implemented in real property today? # Answer Responses % 1 Yes 38 84% 2 No 7 16% Total 100% Note: The number of observations is 45.

Considering the different inputs of the sales comparison, income, and cost approaches, some approaches are more likely to include sustainable factors than others. However, appraisers are challenged in obtaining credible information to support input attributes used in the appraisal method chosen. There is risk in uncertainty for appraisers. Therefore, to avoid this risk, appraisers prefer to rely on verifiable, third-party information to base their assumptions and conclusions for final appraisal value. Again, the appraiser needs to validate the content and source of information to be confident that it is factual, even though provided by a third party. These respondents also concluded that there are insufficient tools and information sources available to appraisers relating to sustainable features (Exhibit 8). The majority of these factors impact the appraiser’s ability to measure and quantify features that influence a property’s appraised value.

Exhibit 12 u Appraiser Satisfaction to Recognize Sustainable Building Features assignments (Exhibit 11). The idea that an insufficient definition of sustainability concepts and elements coupled with educational deficiencies challenges stakeholders in progressing toward sustainable value integration as a standard is supported by further data analysis. Second, overall respondents were not satisfied in their ability to recognize sustainable features (Exhibit 12). Those features rated with higher satisfaction were features that were similar to elements in traditional buildings. The challenge here lies in how to measure and quantify their impacts. The respondents also rated their ability to value the same features between good and poor (Exhibit 13). Again, without information to quantify their impacts, appraisers cannot apply these measurements and data to appraisal methods. Finally, availability of accurate information and data was a need expressed by all respondents in this group, specifically data related to economic costs and benefits, A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 3 Exhibit 13 u Appraiser Ability to Valuate Sustainable Building Features Exhibit 14 u Information and Tools Desired by Group 2 comparable sales, property transactions, and MLS databases (Exhibit 14). In general, respondents are aware of additional opportunities for continuing education and professional development (Exhibit 15); however, these opportunities are not mandatory and not always available to those who face financial and / or location related challenges. Several dominant themes were discovered in the data analysis process to help explain current appraisal practices and the challenges appraisers face when trying to integrate sustainable features into the process. These overarching themes of information collected from Group 1 and Group 2 present an understanding of the barriers to achieving sustainable value integration facing the real estate and building industries.

D a t a A n a l y s i s a n d D i s c u s s i o n The results suggest that a meeting of the minds could be achieved by discovering what each stakeholder group already knows and what they have yet to discover. Targeting this bigger picture, the results may affect thinking on education, federal and state laws and regulations, methodologies, and industries practices relative to sustainable building features / practices. We find that the current status of sustainable value integration in Colorado is progressing, with sustainable building features increasingly recognized and considered in appraisal assignments by 82% of survey participants (Exhibit 5). Respondents confirmed that all building attributes, sustainable and otherwise, should be included in the appraisal process; however, some remain unsure and inconclusive of market interaction due to limited information and data, or their lack of experience or knowledge (Exhibit 7). While the majority of the respondents who have experience appraising sustainable features noted seeing sustainable value integration within the last seven years (Exhibit 6), there remain several dominant challenges facing appraisers and stakeholders within the sustainable value integration process. These challenges are summarized below. First, sustainable feature recognition remains a challenge for a portion of the appraiser population. It was discovered that not all appraisers are able to recognize and therefore, consider sustainable building features for the final appraisal value (Exhibit 3). While the definition of sustainability remains ambiguous and broad, appraisers must decipher the impacts of individual sustainable features as well as those features that create systems within a building to achieve broader sustainability concepts. However, unless appraisers are given specific information about a property’s sustainable features, they are more likely to incorporate those that are visible over those that are not. Despite these challenges, sustainable A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 5 Exhibit 16 u Format Followed by Appraisers for Appraisal Process Q2 What format do you follow in the appraisal process?

Within the standard property appraisal process established by the Uniform Standards of Professional Appraisal Practice (USPAP), an appraiser must examine the subject property and gather all information on the property’s market area, physical characteristics, and market data on comparable properties. Therefore, it will be important to the future success of sustainable value integration in the industry to include sustainability as a topic in the standard curriculum of appraiser education. Second, we found that even though respondents are able to recognize sustainable building features, they are continually challenged by the inability to measure and quantify their economic impacts. Property is a heterogeneous product that exists in constantly evolving real estate markets. Because of this, respondents revealed that they were unsure of how to develop a standardized system to measure sustainable building features. We showed that the data inputs relative to the sustainable features being recognized by appraisers now (Exhibit 16) fit into the current appraisal process described for conventional building attributes. Currently, economic cost and benefits such as return on investment, rent premiums, and utility savings are the primary focus of appraisers’ investigation. Appraisers rely on measureable, verifiable data to create an accurate opinion of market value. Information obtained from energy modeling, performance ratings, and utility bills for those buildings with sustainable features are recommended sources to provide this documented data for appraisers. If this information is not available, the appraiser must find other methods of calculating or obtaining this information, but these processes are not yet standardized. Also, the industry has not yet defined a process to recognize those intangible benefits of sustainable building features, like healthier indoor air quality and higher occupant satisfaction. The standard appraisal process dictates that appraisers collect the property data J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 2 6 B e n t l y , G l i c k , a n d S t r o n g and then perform their analysis according to an appraisal approach. Therefore, in order to consider the impact that sustainable building features have on property value, the benefits of the features first need to be measured and quantified. Without this data, appraisers cannot conduct a thorough comparative analysis. Third, we found that respondents are challenged by a lack of information and data related to sustainable building features. When examining the subject property, respondents noted that they do not get enough information from the builder or owner up front regarding any sustainable features that have been implemented in the property. What we were not able to determine is when sufficient data fails to be documented, are building features simply excluded from the appraisal? If so, how does this exclusion translate to those stakeholders who are trying to promote sustainable building practices? Product specifications provided to the appraiser by the builder or owner would provide relevant information to conduct research on the products’ performance capabilities and thus to estimate an economic value. We found that 74% of respondents who have appraised property with sustainable features require documentation to validate the appraisal (Exhibit 9). Research confirms that uncertainty creates risk for the appraiser. Therefore, reliable, documented information is preferred to reach an accurate estimation of value. Appraisers expressed a need for updated, searchable databases including MLS listings, comparable sales, property transactions, and market data to determine if these features are recognized by the market. This information is crucial to reaching a conclusive opinion of property value. If a reliable property database is not designed, implemented, and maintained, we may see a perpetual exclusion of sustainable features going forward. After the data analysis has been conducted on property features, the appraiser must report the results, according to the USPAP standards. Sufficient information and data need to be available for appraisers to use as a comparison to other values in real estate markets. Using this information, the appraiser will determine which property features the market has recognized. Their report will include the property and market data and adjustments made to value, along with justification for those adjustments. These appraisal reports build on existing property and market data and support future property transactions. To achieve sustainable value integration in all appraisal practices in Colorado, these three major challenges need to be addressed and mitigated. It will be important for appraisal professionals to gain a fluent understanding of sustainable building methods, materials, and technologies through standardized curriculum to recognize and incorporate the value created by sustainable features into their appraisal assignments. The continuing education of appraisers will also play a role as building practices continue to evolve. The development of processes and methods to measure and quantify impacts will be crucial to incorporating value associated with sustainable building features in the appraisal process. R e s e a r c h A i m s R e v i s i t e d The purpose of this research was to discover the current status of sustainable value integration and form an understanding of the processes and challenges facing A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 7 appraisers today in Colorado’s real estate markets. First, we were successful in investigating the nature of sustainable value integration within current appraisal practices in Colorado’s real estate markets. We summarized pertinent terms and provided definitions to create parameters. Next, qualification criteria and the process to obtain appraisal licensure were discussed. Then, research on the governing authority for appraisal standards and practices, laws and regulations, and the typical, step-by-step appraisal process was explained. This information provided much of the demographic information for the study pertaining to the participants. We were able to determine that all active appraisers in the state of Colorado had to have a valid appraisal license. This section also created the baseline for comparison of sustainable value integration practices and regulations against the information collected in objective two. Second, we identified the degree of alignment between state mandated criteria for appraiser licensure and appraiser knowledge of sustainable building techniques, materials, and technologies. Mandated curriculum for initial licensure and continuing education requirements were summarized for the general property appraiser certification as stipulated by USPAP and the state of Colorado. Educational opportunities targeting sustainability topics were not present in the initial curriculum, but were offered in continuing education opportunities. Then, we investigated primary resources for sustainable building information and data provided by professional organizations. Finally, by comparing the mandated appraisal processes to the education and resources available on sustainable building features, we determined that there is a deficiency in the expectations of the appraisal process and the qualification and education requirements of those who are able to appraise. Third, we analyzed the transparency of construction industry knowledge in relation to sustainable building techniques, materials, and technologies compared to the appraisal industry. We utilized information discovered in previous objectives to develop a survey targeting two groups of appraisers: (1) those with experience appraising properties with sustainable building features, and (2) those without experience appraising sustainable building features. We assembled contact information for 322 active licensed appraisers in Colorado using the National Appraiser Registry and the AI Member Registry. Fourth, we explored perceptions of real estate appraisers on the economic implications of sustainable value integration. We were successful in identifying and reporting on the respondents who were aware and unaware of sustainable value integration methods and practices. Those sustainable building features that were being considered and those that appraisers felt should be considered were included in the study. Survey respondent perceptions on those features that add value to a property and the challenges to realizing their potential for impact were also revealed. We conclude that there are three challenges to achieving sustainable value integration in Colorado’s property markets: (1) sustainable feature recognition; (2) ability to measure and quantify economic impacts; and (3) the availability of information and data. J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 2 8 B e n t l y , G l i c k , a n d S t r o n g Limitations of the Study One limitation to the data collected in the study lies in the lack of a uniform definition for the term ‘‘sustainable.’’ Often the term ‘‘sustainability,’’ ‘‘green,’’ and ‘‘energy efficient’’ are used interchangeably in discussions about the same concepts. These phrases may have different meanings dependent on their context and theory of application. Another limitation to the study lies in the types of sustainable building features that were defined for the survey participants. Due to the ambiguity of ‘‘sustainability,’’ ‘‘green,’’ and ‘‘energy efficient,’’ we developed a list of sustainable features to reference in survey questions and responses. The list included site orientation, building envelope quality, HVAC, building performance energy rating, insulation, renewable energies (solar panels, wind), lighting controls, appliances / equipment selection, water efficiency, proximity to community and public transportation, indoor air quality, utility cost (electric, water, wastewater, stormwater), and daylighting. However, this list presents several issues for the study. First, it is comprised of both sustainable building features and sustainable building concepts. Many of these terms could still be considered broad and ambiguous to the respondents. For example, when considering water efficiency, this term could be referring to low-flow plumbing fixtures, gray water systems, xeriscaping, etc. Second, it is difficult to differentiate between a single building feature like insulation and an entire concept like energy efficiency. It is also difficult to define what benefits appraisers need to be aware of and capable of calculating. Is the benefit being seen from the type of insulation, or is the benefit being seen in a better building envelope and therefore lower energy use? Thus, it is difficult to determine which features and / or concepts are good proxies to measure survey inquiries. A third limitation is created by the heterogeneous nature of property and the types of interest they hold. We examined the typical property appraisal process as mandated by the USPAP and the three primary appraisal approaches. We did not consider the nature of sustainable value integration relative to appraisal practices covering specific types of rights and interests relative to the subject property. Also, we acknowledge that appraisers are often held to include certain criteria for the appraisal by their employers. Rules and regulations pertaining to required criteria and their extents for all property appraisals were beyond the scope of this study. A fourth limitation lies in the archival research conducted to discover where education related to sustainability and building practices was present in mandated curriculum for initial licensure and continuing education requirements for appraisers. One limitation to the evaluation of the initial curriculum required for licensure is that we did not review every course outline for content related to sustainability. USPAP defines the topics needed to meet their curriculum requirements; however, they do not develop the specific outlines or lesson plans for each class. Therefore, there are many sources to get a real estate appraisal education. We determined that a review of every class offered was unrealistic. It A p p r a i s i n g S u s t a i n a b l e B u i l d i n g F e a t u r e s 1 2 9 is possible that issues related to sustainable building features are discussed and applied within other curriculum topics. Finally, the survey population also limits the study. Those members who are listed on the National Registry are active and licensed appraisers and those listed in the AI Member Registry are also active and licensed, but have a vested interest in being more experienced and knowledgeable of appraisal issues and trends. These AI members have also taken the initiative to earn an additional AI designation, which means they have additional education above and beyond the requirements of USPAP. Therefore, the appraisal population selected for this survey may have been slightly in favor of the study because of their additional experience and education. Overall, there was still a portion of the survey population that was not aware of and did not have experience with sustainable value integration practices in appraisal. C o n c l u s i o n The literature review proposed several needs for further investigation into opportunities to mitigate challenges facing stakeholders investing in sustainable building practices / systems. Previous research expressed a need for further research to provide clarification on several fronts in order to achieve sustainable value integration in real estate appraisal. First, education and continuing education requirements need to adopt sustainability into their curriculum. We found that all appraisers are not able to recognize and value sustainable building features. Mandated education does not have a specific focus on sustainable building concepts and features. Continuing education opportunities related to sustainability are available, but not mandatory. The incorporation of education specifically focused on issues related to understanding, integrating, and reporting on sustainable building features needs to be seriously considered by governing authorities in order to mitigate this deficiency in appraiser knowledge. Second, the need for a standardized measurement system to assess qualitative and quantitative benefits of sustainable building features and their economic impacts to real estate property has been expressed by other researchers. Our results also confirmed this need. Appraisal approaches are based on quantitative inputs and mathematical formulas. Survey respondents were found to be unsure of how to measure certain tangible and intangible benefits resulting from both visible and not visible building features. These respondents expressed a need for a method to measure and quantify the various economic impacts of sustainable building features and a standardized method to input these figures into an analysis. Third, researchers have suggested that property transaction databases be created and / or re-furbished to enable comparative studies of properties with sustainable building features. Again, our findings confirmed that this type of information is necessary and crucial to the success of appraisers in being able to collect data and report on market value. Respondent to our survey expressed a need for a new type J O S R E V o l . 7 N o . 1 – 2 0 1 5 u u 1 3 0 B e n t l y , G l i c k , a n d S t r o n g of searchable database or updating of existing databases to include sustainable building features. However, it is up the appraisers and other real estate professionals to investigate each property and include this information in these databases. Fourth, due to the small sample size, several things could be done in future research to confirm and strengthen this study. First, a survey of the non- respondents could be done to help confirm whether the results are representative of a larger population. Second, additional questions could be added to the survey to measure the impact of LEED certification and ENERGY STAR ratings on appraisal practices. It may also be helpful to further distinguish the types of commercial property that are appraised to ascertain if the properties are ‘‘high profile’’ where sustainable features are well known and advertised when leasing or selling. Finally, our goal was to contribute to the limited empirical data available on what is taking place in the property appraisal industry relative to sustainability, rather than proposing additional suppositions as previous researchers have done. We discovered, from a small population sample of Colorado appraisers, how many appraisers were considering sustainable building features in appraisal assignments. Sustainable building features being recognized by appraisers were found, but their impact on final appraisal value was not. In general, the features being considered are those that are currently quantifiable. From those features, it was revealed they are not being recognized by all markets, and therefore not impacting final appraisal value. We conclude that it will be necessary to mitigate existing challenges and fulfill research and development needs in order for the building and real estate industries to realize the full potential of sustainability and its impact on property value.
