| dc.description.abstract | There is an increasing focus on reduction of the energy use in buildings in Norway. Today there are two passive house standards in Norway, one for residential buildings and one for non-residential buildings. In this master thesis, the focus will be on energy use in swimming halls. However, there are no technical regulations or standards regarding energy use in swimming halls.
Swimming halls differs from ordinary sports halls and other building types by the high indoor air temperature, air humidity and water consumption. The indoor air temperature together with a high water consumption and water evaporation from the pools makes the energy demands for a swimming hall much higher than in other buildings. This is also making swimming halls far more complex as a building type.
This thesis is based on Holmen swimming hall, which is going to be built outside Asker. Holmen swimming hall is to be built according to passive house standard. However, there are no clearly expressed demands for effect and energy use for swimming halls in passive house standard, NS 3701. In this master thesis, a methodology for describing energy use in swimming halls based on research from Centre for Sports Facilities and Technology (SIAT) is developed. The thesis describes building physical aspects and the energy balance in Holmen swimming hall. Dew point calculations and the outdoor climate s influence on the maximum indoor moisture content is described in this thesis. In addition, the use of photovoltaic cells and thermal solar energy collectors is evaluated.
It is quite comprehensive to calculate the energy requirements for a swimming hall. It is not possible to calculate the energy use of a swimming hall in SIMIEN alone. SIMIEN is not adapted to swimming halls, as it is not possible to calculate energy requirements associated with the pools and its systems. Therefore, a calculation model for technical facilities regarding the pools and thermal installations in the swimming hall has been developed in the work with this thesis. The annual energy use for Holmen swimming hall was calculated by means of SIMIEN and this calculation model. The results from the calculations, show that Holmen swimming hall has a yearly energy use of 1 937 455 kWh or 2844 kWh/m2 water surface. It is concluded, based on research from SIAT, that Holmen swimming hall should have a yearly energy use closer to 2000 kWh/m2 water surface. | en |
