Abstract: Ralph Evins¹,², Philip Pointer¹, Ravi Vaidyanathan² ¹Buro Happold, 17 Newman Street, London, W1T 1PD, UK. ²University of Bristol, Tyndall Avenue, Bristol, BS8 1TH, UK. August 30, 2011 involves the consideration of several objectives simul We present a new approach to the optimisation of Double-Skin Facades (DSFs). Parameters defined possible geometries, shading devices, openings and ventilation paths, as well as control schedules for their operation. A genetic algorithm was used to discover the best configuration and control strategies for a given scenario from scratch, rather than using a particular configuration type. The algorithm performed a thermal and air-flow simulation of each proposed solution using EnergyPlus. The optimisation process has been illustrated with a case study. In addition, the process has been applied to a range of use types and the results examined graphically to derive innovative design guidelines (a process known as “innovization”).
