Building design involves the optimization of factors affecting building performance such as building functions, comfort, safety, and energy. Building performance models (BPMs) help designers to evaluate and optimize such factors. However, the lack of design capabilities to validly describe human-building interactions for buildings under design may contribute to the development of inaccurate BPMs and the performance discrepancy between predictions and actual buildings. To address this challenge, a computational framework is proposed to increase the estimations performance of BPMs. The framework uses artificial neural networks (ANNs) to combine and describing design-specific human-building interactions captured by using immersive virtual environments (IVEs). The framework produces an augmented BPM that can predict building performance taking human-building interactions specific to a new design into consideration. It incorporates a feature ranking technique allowing designers to assess impacts of contextual factors on human-building interactions. The paper focuses on providing details of theories, experiment and data collection designs, and algorithms behind the framework as a companion paper of [1]. •A framework for combining contextual factors with building performance models to enhance their predictive performance.•Computation for determining impacts of contextual factors on human-building interaction.
