The local health authority’s buildings

Investing in renewable energy

landstingsfastnext —

The local health authority is working long-term and systematically with energy effectiveness for electricity, heating and cooling in their own buildings. They are also actively driving the transformation efforts towards more sustainable energy solutions. The long-term vision for 2030 is that purchased energy usage per unit area of each property is reduced by half compared to 1995 levels, ”energy factor 2”. Sundsvall hospital snow-cools to save energy. Since the summer of 2000, Sundsvall hospital has been using snow for both comfort-cooling as well as for cold storage, with very good results.
The cooling system in Sundsvall is based on a world-leading technique, which involves large-scale storage of snow.  Simply put, it involves making the most of the snow from the skies and from the city’s snow clearing, and then using the cold meltwater to cool the hospital. The snow-based cooling system has reduced the hospital’s electricity consumption needed for cooling by 90%. Additionally, they have been able to phase out the environmentally hazardous refrigerants. A system built on the same principle has now been installed for cooling Sapporo airport in Japan. Härnösand local health clinic – Using the sun for electricity and heating When the sun rises over the southern straights of Härnösand, a humming noise can be heard from the roof of Härnösand local health clinic (formerly Härnösand hospital). It’s the sound of seven solar collectors as they turn towards the sun to then provide electricity and heating for the day. The system includes a showroom, which has attracted more than 20 ambassadors and several ministers.
The Foundation for Research on Concentrated Solar Energy operates the system.
