Energi- och klimatsimulering för nybyggnation av äldreboende med jämförelse mot BBR-krav och Miljöcertifiering

A nursing home for old people is going to be built in Edsbyn, a community in Hälsingland, Sweden. The building needs calculation of energy use to receive a building permit. Seven different indicators in Miljöbyggnad were also examined. Miljöbyggnad is a Swedish environmental certification a building can acquire. In the project some changes in selected parameters of the buildings constructions and installations are examined to see how it affects the need of power to heat and the indoor climate. To obtain answers some simulations in IDA-ICE simulation program have been done together with a literature study. The results show that the building fulfills the requirements of specific energy use and mean value of the U-values that are set in BBR24. The building also fulfills the requirements of the number of primary energy and mean value of the U-values that is set in BBR25. Of the seven indicators in Miljöbyggnad that were examined two received the grade GOLD, three received SILVER and two received BRONZE. When building parameters are varied the results show that the largest difference in heating power is when changing the thickness of insulation and the largest difference in PPD, Predicted Percentage Dissatisfied, is when changing the indoor temperature
