Snow heap becomes cooling facility in Sundsvall

The snow that falls on streets and squares has to be removed, and snow heaps are often an inconvenience for municipalities. But the snow heaps can also be of benefit. Västernorrland County Council now makes use of the cold in snow to save energy.

Energy-efficient school with environmental focus in Storfors

Vargbro School in Storfors in Värmland is one of the most energy-efficient schools in Sweden. It is largely heated by the people who are in its buildings. Only during cold days in winter holiday periods is there a need to supplement the heating.

District heating replaces cooling machines at Hägglunds Drives in Mellansel

Cold water from the lake replaced cooling machines at Hägglunds Drives in Mellansel. It did not just reduce electricity consumption but noise, surplus heat and the risk of leakage of refrigerants too.

Low energy use at Västervik sports centre

Västervik, in south Sweden, has saved both energy and money since modern energy efficiency equipment was installed in its swimming pool and bowling alley. Energy use in the sports centre has so far fallen by around 830 MWh/year.
