Design Aids for Supplementary Lighting Design in India

Design Aids for Supplementary Lighting Design in India This paper presents a design aid which will help to integrate daylight in indoor lighting and optimize the use of artificial lighting in buildings for different climate zones in India. An index, average daylight factor is utilized for calculating the incident useful daylight in an indoor space. These calculations are further used in deriving nomographs which can help to determine the optimum percentage of fenestration/floor area for a typical small office. The use of these nomographs will be advantageous in the initial stages of planning an energy-efficient building by optimizing on the measure of fenestration area. The results obtained from the nomographs are compared with the simulation results from the VELUX daylight visualizer tool and are found to be within acceptable limits of error (< 10%). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

This paper presents a design aid which will help to integrate daylight in indoor lighting and optimize the use of artificial lighting in buildings for different climate zones in India. An index, average daylight factor is utilized for calculating the incident useful daylight in an indoor space. These calculations are further used in deriving nomographs which can help to determine the optimum percentage of fenestration/floor area for a typical small office. The use of these nomographs will be advantageous in the initial stages of planning an energy-efficient building by optimizing on the measure of fenestration area. The results obtained from the nomographs are compared with the simulation results from the VELUX daylight visualizer tool and are found to be within acceptable limits of error (< 10%).
