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.
We are presently working on problems associated with kindergartens which, with regard to indoor climate, are quite over populated. Typically, the kindergartens are around 300 m2 inarea and 700-1,000 m3 in volume, with 60-80 children, and withnatural ventilation only. The basic air change rate is 0.2-0.4 ach. As we have shown*, users have a tremendous impact on air infiltration which, in the kindergartens, rises from the basic 0.2-0.4 to 0.7-1.5 ach when the kindergarten is in use.
