Cóstola, B. Blocken and J.L.M. Hensen Building Physics and Systems, Eindhoven University of Technology, the Netherlands ABSTRACT This paper presents ongoing research about an integrated approach to perform high resolution heat, air and moisture (HAM) simulation of whole buildings. There are several HAM modelling tools, with different space and time resolution. The integrated approach establishes run-time external coupling of existing tools (building envelope HAM, BES, CFD) and utilizes the capabilities of one tool in an attempt to compensate the deficiencies of the other. The paper presents the literature review of approaches for domain integration, the physical processes as dealt with by existing tools, coupling requirements and it addresses the importance of validation and coupling necessity decision procedures. INTRODUCTION Building simulation can be potentially applied to analyse important building performance aspects such as thermal comfort, mold growth and condensation (Crawley et al. 2008). The uncertainty associated with such simulations can be high, and incorrect simulation results can lead to design with adverse effects on health, comfort and functionality of space, which in turn might lead to unwanted extra cost (Mudarry et al. 2007). In some cases, high resolution simulations are needed for heat, air and moisture (HAM) transfer to obtain more accurate results. Such high resolution simulation of whole buildings might require coupling of different geometrical and physical domains which involves the exchange of variables on time-step basis. In whole building HAM modelling, we focus on three geometrical domains: exterior, building envelope and interior, and three physical domains: heat, air and moisture. In recent years, the use of
