Description: Tegs Kyrakan, was built in 1969 and is located in Umeå, Sweden. The building, now a protected structure of historical significance, was constructed in the Brutalist style of architecture, making it unique for a Church building in Sweden.
Church buildings typically have large single-zone areas and as a result they present challenges when improving energy efficiency and thermal comfort. Tegs Church uses a large amount of heat energy when compared to the average thermal energy usage in a Swedish building. It uses electric floor heating and is maintained at a constant indoor air temperature of around 20ºC during winter. In this study a mechanical air change system and floor heating system is investigated in order to optimize the occupants' thermal comfort and to minimize energy usage.
