Parametric optimisation of space layout for the energy performance of office buildings

Tiantian Du (Delft University of Technology)

Architectural design greatly influences building energy performance (BEP), andenergy-efficient design is therefore often studied. Architectural space layout also can affect BEP. However, only a few of the numerous studies on energy-efficient design considered the effect of space layout. Within these studies, the isolated effect of space layout on the BEP has hardly have been analysed systematically.The framework of Performative Computational Architecture (PCA) had been proven to be effective to improve BEP. PCA includes form generation, performance evaluation, and computational optimisation. With this framework, the building’s geometry and material properties are parametrised, and the performance is assessed for different combinations of design parameters. It aims to find the proper parameters that satisfy the defined objectives. This method can include the generation and assessment of space layouts. However, only a few studies have tried to combine the automatic generation of space layout with energy performance optimisation; nor the systematic analysis of the effects and relations between space layout and energy performance.
