Abstract: Comparisons of measurements at a 1:1 scale mock-up with detailed thermal simulation offer a great opportunity for model evaluation. Due to the composition of the investigated glazing system (8 mm + 8 mm PVB laminated glass, solar protection coating, 5 mm glass and 8 mm glass) the authors extended the existing complex fenestration model (CFS) of the multizone building model of TRNSYS by adding heat capacity for glass layers. Simulation results with and without glass capacity consideration are compared to measurements at a 1:1 scale facade mock-up. The results show that the consideration of heat capacity of the glass layers improves the match to measured data significantly. The extended model resolves issues of high peak temperatures and a shift in time of occurrence. The simulation results of the improved CFS model match closely to the measurements of the mock-up.
