Integrated building performance simulation: progress, prospects and requirements

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.
