A Framework for a Building Energy Model to Support Energy Performance Rating and Simulation

Recent advances in Building Information Modeling (BIM) and the emergence of mandatory building energy codes and specifications encouraged the integration of energy performance rating and energy analysis and simulation in building design and operation. Building Energy Performance (BEP) ratings and simulations and the Architecture, Engineering and Construction/Facility Management (AEC/FM) disciplines are converging. However, current BIM databases contain data that support, mainly, AEC/FM tasks. Few attempts have been made to include data that support BEP rating and simulation. In this study, a conceptual framework for a Building Energy Model (BEM) that captures the data needed for building energy performance rating and simulation has been presented. A case study, using a warehouse, is used as a test-bed for proof of concept and for validation of the developed framework. The ultimate goal is to develop a data model that supports the integration of BEP rating and simulation to facilitate building design and operation.
