Dynamic Thermal modelling and CFD simulation techniques used to influence the design process in buildings

Roberto Padovani, Dominique Hes, Finbar McLaughlin

Abstract: This application paper outlines some innovative building simulation methodologies used to predict thermal performance of complex energy efficient systems using commercially available softwares. Industry case studies are presented to demonstrate how simulation can influence the design process with requirements varying from zero carbon emissions to optimum thermal comfort. Simplifications used to reduce computational time and handle software limitations are assessed in solar evacuated collectors sizing and performance assessment. Some of the software limitations and their solutions presented in this paper are outlined in Table 1. Table 1 Limitations of the software used and approach applied to minimise their impact SOFTWARE LIMITATION APPROACH TAKEN regards to model accuracy and the ability to influence the design decision process. Building simulation models are presented with a fit for purpose approach from simpler models to detailed HVAC models used for system performance and thermal comfort assessments. Keywords: thermal simulation, CFD, IES VE, HVAC, Desiccant, Solar, In-slab cooling.
