Evaluation of reference modeling for building performance assessment

Lifecycle building performance assessment (LBPA) practices are being increasingly applied on existing buildings to ensure that performance requirements are fulfilled during building service-life. LBPA is a multi-disciplinary and information-intense process that requires computational tools for information management and decision support. We have previously developed a computational reference model (CLIP-Core) that supports various component-based LBPA practices. When CLIP-Core is considered to be used, it needs to be adapted to the specific context it addresses. We developed two such domain models, CLIP EPI-CREM and CLIP-CMU, for two existing LBPA practices. This paper addresses the evaluation of CLIP-Core and its potential in supporting various requirements. Hereto, we first discuss CLIP-Core and the two domain models. Then we present the evaluation results based on the domain models and their development processes. Finally we discuss guidelines for extending CLIP-Core and recommend technologies and alternative architectures that can increase CLIP-Core's usability.
