Educating staff, parents and caretakers at a Swedish playschool on energy conservation measures has reduced the school's annual energy consumption by 10 %. This project carried out at the Lagradsgatan playschool shows that education is an effective way of achieving energy savings through simple measures which have a short payback period. Due to the success of this project in the Eskilstuna municipality, advice on energy conservation will be given to all playschools in the area.
Experimental U-values based on measured heat flows through the walls of some houses have been found to be significantly higher than predicted by conventional calculation procedures. The work was carried out in ordinary occupied houses, and included measurements on party, internal and external walls. There are a number of possible reasons for the differences including thermal bridging, high thermal conductivities and excessive air movement in the wall cavities and behind plasterboard dry lining.
