WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad. Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ”thermal climate summer” and the ”daylight”. The simulation program VIP-Energy was used to investigate how the different solar shadings: blind, marquis and fixed screen affected the cooling need of the second floor of the preschool. Possible actions for increasing the inlet of daylight are discussed. Two measures were identified: increasing the glass area and changing to windows with higher transmission of light. If the information about the use of energy which has emerged in this thesis is considered it will not be sufficient to only improve the ”thermal climate summer” and the ”daylight” in order to improve the level of certification.
