Nutzerzufriedenheit mit dem thermischen Komfort in Bürogebäuden mit Umweltenergiekonzepten

This paper presents results of a long-term evaluation of occupant perception of and satisfaction with thermal comfort in two neighbouring office buildings in Freiburg. They were obtained in field surveys by daily questioning and accompanying measurements in high temporal resolution. One office building is conditioned during summer according to a night-time ventilation concept and the second uses concrete core conditioning and a supply/exhaust ventilation system. Based on the survey data and a regression analysis, a model was calculated to predict the comfort temperature depending on the cooling concept employed. Results were compared to the comfort models of DIN EN 15251
