A Facade mapping method to understand human comfort in buildings with highly glazed facades

Tüzer, Ceren.
The energy demand of societies increases continuously with related to technological improvements, population increases and daily needs. Building sector is one of the highest energy consumer sector. Office buildings are also critical type of buildings, because these types of buildings generally accommodate lots of occupant and there is high demand of energy for lighting, heating, ventilation, and air conditioning to provide indoor air quality, thermal and visual comfort. The buildings with glass curtain wall that is used for high rise office buildings mostly, are also critical type of buildings in terms of thermal performance and user comfort which effect the energy consumption. This study aimed to show the probable impact of glass curtain wall on thermal performance and user comfort with facade mapping method. For this aim, eight buildings that are cladded with glass curtain wall and located in Ankara, were examined as the case buildings. Photos were taken from their facades for fall, winter, spring and summer seasons. To determine the percentage of facade closed by the users that are forced to take precaution for their thermal and visual comfort, the facade mappings of the buildings were created by the help of these photos. The results were discussed according to direction of the facade and the season. The results of four case buildings were compared with properties of glass which were belong to these case buildings. According to the results, the highly use of internal shading elements is due to the occupants trying to provide thermal and visual comfort. The rate of internal blind’ use is partially related with thermal properties of glazing.
