Title: GSWB’s holistic renovation concept increases energy efficiency of apartment complex
With respect to thermal comfort and HVAC installations and due to antiquated furnaces, an apartment building complex in Schwarzach (province of Salzburg, Austria) no longer met today’s requirement for modern cost-effective and energy-efficient living. The specifications for renovation measures for the complete complex included improvement of thermal insulation, installation of new heating systems, and the complex’s own already proven micro-district heating system, which is connected to the town’s own biomass district heating network. Part of the apartment complex that had to be demolished and rebuilt was additionally equipped with thermal solar systems.
