    Abstract

    This paper describes an empirical validation study undertaken on two identical full‐size buildings within the scope of the IEA ECB Annex 58 project. Details of the experimental configuration and monitoring are included, together with results from measurements and from predictions made by 21 modelling teams using commercial and research simulation programs. The two month side‐by‐side experiment was undertaken on buildings with high levels of thermal mass and in a period with high solar gains. The detailed specification and associated measurement data provide a useful empirical validation dataset for program testing. Results from the modelling demonstrate good agreement between measured data and predictions for a number of programs, both in absolute predictions of temperatures and heat inputs as well as dynamic response. On the other hand, a significant number of user input errors resulted in poor agreement for other programs, especially in the blind validation phase of the modelling methodology.
