| Summary: | One of the goals in this thesis is to make an energy balance for the new bathhouse in Kiruna. Another goal is to investigate whether it is possible to environmentally certify the building with bathhouse operations. Additional goal is to check whether the Upphandlingsmyndighetens sustainability criteria for bathhouses are possible to use when building bathhouses. The background to this project is that Kiruna are getting a new bathhouse because the old one is to be demolished. What has been investigated in this project is the criteria for environmental certifications and whether a bathhouse business can meet those criteria. The indicator that has been of most interest is energy use. The energy balance was made through measurements and conversations with experts from the consultant company We group and by simulating the energy balance using the software VIP Energy. The work has resulted in an energy balance being created. A comparison is made between only the building and the building with a bathhouse activity. The environmental certifications were investigated, and they were found that none of the selected environmental certifications worked for the building with bathhouse activities since they use too much energy. The National agency for public procurement sustainability criteria for bathhouses generally works but need to be adjusted to be more useful.work but should be used as an aid until the criteria are completed. The energy balance showed that the bathhouse with operations had an energy consumption of 323.9 kWh / (m2, Atemp) in one year. The bath house without activity had an energy consumption of 44.3 kWh / (m2, Atemp) in one year. The building with bathhouse operations has an energy performance premiere energy of 351.5 kWh / (m2, Atemp) in one year and the building without bathhouse operations is 61.1 kWh / (m2, Atemp) in a year. The requirement from BBR on energy performance is 125.5 kWh / (m2, Atemp) in a year.
