Empirical validation of building energy analysis tools by using tests carried out in small cells

A large empirical validation exercise was recently completed in the framework of International Energy Agency (IEA) Solar Heating And Cooling (SHAC) Task 22 (Building Energy Analysis Tools) (Sub-task A3 « Empirical validation »). It includes a set of 10 modelling teams using different software programs from Europe and USA. ETNA test cells (EDFFrance) have been used for this exercise. Four rounds have been completed, only the first round in blind way. At the end, different modelling problems have been corrected. This exercise has been totally useful for each participant to evaluate and compare its code to other ones.
