Energy savings in a school : Study of the ventilation and lighting systems in the school of Jädraås

The aim of this project is to calculate how much energy could be saved in the School of Jädraås, in the municipality of Ockelbo. The objects of study were the lighting and the ventilation systems, not only because of the energy saving but due to the comfort also. After our study, the municipality wants to use our results to improve all their municipality buildings and save as much energy as it is possible in the whole municipality. We analyzed the hours when the ventilation system is working during the whole year, and we calculated how much energy could be saved if the amount of working hours were decreased or if new devices, as heat exchangers, were installed. In the lighting system part, the aim was not only the energy saving, but the comfort also. The currently lighting system is quite bad, specially in the dinning room, where bulbs are still lighting the room. These bulbs, anyways, should not be changed in the next ten years. The lighting system in the learning rooms is also old. Although there are fluorescent lamps already, some new lamps with lower energy consumption and better efficiency can be installed
