A Characterisation Framework for Parametric Building Performance Simulation Tools

Abstract

Implementing Building Performance Simulation (BPS) in a parametric design framework is a prevalent way of facilitating environmental assessments in early design stages. However, no up-to-date overviews of potential approaches are available, and no characterisation frameworks adapted for parametric BPS tools are present. In this study, such a framework was developed and its use demonstrated through an investigation of eleven available BPS tools for the parametric design framework Grasshopper®. It was found that the framework was able to successfully differentiate tools based on the level of BPS expertise integrated in the tools, and the allocation of responsibility for data entry and interpretation. A contrast was found between streamlined tools, and tools which provide more versatility. The characterisation framework, and the resulting overview of approaches, can be used to guide the future development of parametric environmental analysis frameworks for buildings.
