HYSS helps Skanska in realizing their goal of creating net zero-energy houses on commercial terms!

Published 13.01.2021
Free Energy supply the heating system to Skanskas latest cutting-edge project Norra Vitsippan in Salem, outside Stockholm. Along with NREP, Skanska is developing a residential area with 108 apartments, divided into seven houses as a net zero-energy project.

Norra Vitsippan in Salem is one of Skanskas new housing projects which is taking steady steps towards climate-neutral buildings. The houses receive their electricity and heat supply from solar and thermal energy. Free Energy's HYSS High Power provides the heating and hot water. The energy demand is decreased by 80 percent by connecting solar heat to a hybrid heat pump. With Free Energy's innovative HYSS system, solar heat is provided to a geothermal heat pump which renders an extremely high heat factor. HYSS' unique control system utilizes solar heat where it is most advantageous. The result is a doubling of the heat factor for the heat pump compared to conventional technology.
