| Summary: | This report is the product of the course AF101X, a bachelors degree in Samhällsbyggnad at KTH. . The task of the course is to design a small house at a given location and also implement a deepening study. The house in this report is located in Kiruna in the north of Sweden, where the climate is much colder than in the rest of the country. The deepening study of this report is to evaluates how realistic passive housing north of the Polar Circle is based on those facts. The house will to some extent be designed to fit the passive housing standard. This standard serves also as a base for calculations in account of energy use. The passive house standard given in FEBY 12 says that the maximum energy use for a passive house is allowed to be 31 kWh/m2, year and the heat loss coefficient (VFT) is allowed to be 19 W/m2Atemp. The main part of this report have been to dimension the climate shell as good as possible and the heat exchange the ventilation system to recycle as much energy as possible. The result was that the heat loss coefficient is 17 W/m2Atemp and the energy use is 51 kWh/m2,year, which means that the passive housing standard could not be satisfied with the given conditions.
