Abstract

The aim of this study is to quantify the gap between the simulated energy need of an office building with simplified and detailed glazing models. We studied triple, quadruple and quintuple windows and concluded that differences in energy need of similar cases with different glazing models reached 1.9 and 6.4 kWh/m2 in space heating and cooling needs respectively. Significant relative differences in heating and cooling were up to 14% and 40% respectively. Largest differences appeared with triple glazing and smallest with quadruple glazing. Compared to detailed window models standard triple and quadruple glazing models resulted in lower heating and higher cooling needs, whereas in case of quintuple windows the results were the opposite.
