Modelling and optimisation of a biomimetic façade based on animal fur

Matthew Webb, Eckhart Hertzsch, Ray Green

Abstract: Biomimicry offers opportunities to advance the development of flexible, adaptive facades. This paper focuses on fur heat transfer and translates the distinctive performance characteristics of animal fur to building envelopes. A time-dependent mathematical model is developed to describe the application of fur to a façade. An optimised ‘fur’ layer was shown to have a thermal conductivity of 0.055 W/mK, compared with deer fur at 0.091 W/mK. When an optimised, fur-lined façade was compared with a conventional lightweight façade under sunny summer conditions, heat gains reduced by up to 50%. During a winter scenario, heat losses to the external environment were reduced by at least 50%.
