Entwurfskonzeptionierung einer Werkhalle durch integrale Analyse von Tageslicht und thermischem Raumklima

Andreas Lahme

Abstract: The task formulation is the examination of daylight use and thermal room behaviour for a working hall used for educational purposes. Two designs with side windows and different shed roofs exist: Shed roof with 28°/62° slope and shed roof with 45° slope. The examination is done by lighting simulation and thermal simulation: Investigation of luminance, daylight factors, daylight autonomy under an overcast sky, daypaths of solar radiation for different building variations, investigation of room temperature, overheating frequency, heat balance, solar entries, heating energy demand, etc. for different building variations. The evaluation of the simulation results shows that the 28°/62° shed roof with shaded and downsized side windows is the better solution. The 45° shed roof leads to higher overheating rates and hardly increased daylight use, further it does not reduce the heating energy demand.
