Norra Vitsippan, Salem - Net zero-energy houses on commercial terms

Norra Vitsippan, Salem - Net zero-energy houses on commercial terms

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

Free Energy contributes with cutting-edge technology for Skanskas housing project Norra Vitsippan in Salem, outside Stockholm. Energy consumption for heating and hot water is decreased by 80 percent due to HYSS. With solar cells, solar heat and HYSS it is possible to achieve net zero-energy houses on commercial terms.

Skanska Rental Housing has developed a climate-smart zero-energy house that can offer competitive rents. The project consists of 108 rental apartments in seven buildings.

- Our objective is to take one step in the pursuit of becoming climate-neutral and to redraw the map for how we solve the energy issue for multi-family-homes. So far, most housing developers have struggled to reduce energy consumption through denser houses and better insulation, but this is a completely new step for us to reach even further, says Anders Degerstedt, Business Developer at Skanska Rental Housing..

The real estate company NREP bought the Norra Vitsippan project from Skanska earlier this spring. The project is one of many in NREP's goal in developing climate-adapted buildings with long-term value for tenants, investors and the society in general.

- We want to be pioneers in sustainability and are already working to convert all our properties to 100 percent renewable energy as a result of joining the RE100. This is the beginning towards the next step. We find the HYSS-solution delivered by Skanska very interesting because it combines technology that already exists in a relatively simple way. It is definitely possible to come down to a net zero solution, says Rickard Langerfors, Housing Manager at NREP

This is how HYSS (Hybrid Solar System) combines geothermal heat and solar energy.
