Assessing thermal comfort conditions: a case Study on the METU Faculty of Architecture building; the case of ODTÜKENT

Çakır, Çağrı
The aim of this study was to evaluate the effects of environmental design parameters on thermal comfort conditions in the METU Faculty of Architecture Building located in Ankara. The building had some problems in terms of indoor climatic conditions, both in winter and in summer. It was evident that some design parameters caused this undesirable situation. The study therefore focused on understanding and evaluating the effects of design-dependent elements such as thermal mass, the size and orientation of windows, shading and vegetation on thermal comfort conditions in the case study building. While conducting this study, data loggers were used to record temperature and humidity data in predetermined rooms. Data was collected during certain periods in July, August, and September 2006. The data collected was analyzed statistically and hypotheses were tested using ANOVA. This study showed that the effect of thermal mass was almost the same for the rooms investigated owing to the fact that the entire building had been constructed with concrete curtain walls. In terms of thermal performance the number and orientation of the exterior walls, orientation and size of windows, room heights and also sun shading with surrounding vegetation were most effective design parameters for the rooms investigated.
