Multi-objective optimisation of the configuration and control of a double-skin facade

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 partic-ular 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”).
