BIM-based generative design approach for integral residential energy-efficient façades

Abstract

Residential buildings significantly impact global energy consumption. Appropriate residential façade designs can considerably reduce energy consumption in maintaining indoor comfort. Current research on residential energy-efficient façade design primarily focuses on single-objective studies and exploring parameter boundaries of isolated façade elements, neglecting holistic perspectives. It results in a research deficiency in multi-objective optimisation and integral design approaches. This study presents an innovative AI-aided methodology integrating Building Information Modelling (BIM) and Generative Design (GD) to automate multi-objective optimisation and energy-efficient compliance assurance in Australian residential façade design. Through the developed BIM-based GD program, well-founded and compliant integral energy-efficient façade designs can be generated and modelled automatically and efficiently.
