Biomimetic inspired, natural ventilated façade – A conceptual study

Biomimetic inspired, natural ventilated façade – A conceptual study In this paper, the authors elaborate an adaptable curtain-wall façade design concept that combines façade greening with biomimetic approaches. It begins with an overview of façade greening. Next, the paper takes a more in-depth look at prairie dog burrows and the modular growth of barnacle colonies as sources of biomimetic inspiration, including how they may be applied in technology and brought together with façade greening. The concept is expected to act contrary to the urban heat island effect by naturally cooling external building walls and thus reducing the energy needs and greenhouse gas emissions associated with artificial cooling of buildings. This is considered important, as our cities are heating up more and more, resulting in increased energy demand. The promising information gained from lab experiments on scaled façade models, based on continuous wind-generated air circulation between the building’s external wall and the façade, further initial calculations regarding natural convection, and the additional cooling effect of façade greening, can be considered a sound basis for future developments and discussions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Facade Design and Engineering IOS Press

Abstract

In this paper, the authors elaborate an adaptable curtain-wall façade design concept that combines façade greening with biomimetic approaches. It begins with an overview of façade greening. Next, the paper takes a more in-depth look at prairie dog burrows and the modular growth of barnacle colonies as sources of biomimetic inspiration, including how they may be applied in technology and brought together with façade greening. The concept is expected to act contrary to the urban heat island effect by naturally cooling external building walls and thus reducing the energy needs and greenhouse gas emissions associated with artificial cooling of buildings. This is considered important, as our cities are heating up more and more, resulting in increased energy demand. The promising information gained from lab experiments on scaled façade models, based on continuous wind-generated air circulation between the building’s external wall and the façade, further initial calculations regarding natural convection, and the additional cooling effect of façade greening, can be considered a sound basis for future developments and discussions.
