Abstract [en]

The municipality of Uppsala together with eight constructors are currently planning a sustainable residential area in Östra Sala backe. The aim of this report is to identify the main factors that are important when calculating the specific energy use in an apartment building. Two previous similar projects, Västra Hamnen in the city of Malmö and Hammarby Sjöstad in the city of Stockholm, are studied and simulations in VIP-energy are performed. Sensitivity analyses concerning the indoor temperature, the efficiency of FTX-systems and the U-values of windows are also executed.

The simulations are based on information from the constructors of Östra Sala backe, standard values and mean values from Västra Hamnen and Hammarby Sjöstad. The results show that differences between the estimated and measured values in specific energy use can reach about 50 %, or 25.2 kWh per m2 ATEMP and year, and that the efficiency of the FTX-system is the most important parameter.
