The largest solar cell plant in Sweden
A passive house is a very well insulated building, which almost entirely is heated by the people and machines, such as computers and appliances, that it houses. The school in Alingsås will also get additional energy from its roof.
On that roof 1 300 square meters of solar cells have been installed. They will generate electricity that can be used in the school or the gymnasium, or be sent out on the power grid.
The roof of the gymnasium will also be special. It will be covered by Sedum plants, which will form a “green” roof. Sedum is well suited for use on roofs as it needs only a thin layer of soil, withstands draught well, and protects the roof’s sealing layer from UV radiation.
