Projects in the domain of architecture, engineering and construction (AEC) typically involve diverse parties, each bringing specific information into these projects. Therefore, a well-functioning information flow throughout the complete building life-cycle is crucial. This is also the case for the information flow within one of the subdomains of the AEC domain, namely the domain of building energy performance Simulation (BEPS) (Bazjanac et al. 2011a). In this article, we will therefore look into one of the diverse options to make information for BEPS increasingly interoperable.
