Energy Pathfinder Webinar: Energy Use & Thermal Comfort in a Large Single-Zone Building (Tegs Kyrkan) during Cold Season, Umeå, Sweden

Thursday 27th August 2020 11:00 -12.00 GMT +1: Energy Use & Thermal Comfort in a Large Single-Zone Building (Tegs Kyrkan) during Cold Season, Umeå, Sweden

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.
