Integrated building performance simulation: Progress, prospects and requirements

• Summarises the state-of-the-art in building performance simulation.
• Outlines challenges relating to a high integrity representation of building performance.
• Identifies emerging challenges that will dictate new directions for BPS development.
• Characterises barriers to collaborative development in the field.

This paper is concerned with the role of Building Performance Simulation (BPS) in assisting with the creation of energy efficient habitats. It characterises achievements to date in a non-program-specific manner and in relation to the ultimate goal of providing practitioners with the means to appraise, accurately and rapidly, the multi-variate performance of built environments of arbitrary complexity. The shortcomings of the state-of-the-art, when assessed against this goal, are used to identify future development priorities.
