Användning och lagring av solenergi flerbostadshus från 50-talet

An increase of the use of renewable energy sources is a part of the solution to tackle the climate change problems. Solar energy is a renewable energy source used for both electricity and heat. The housing sector has a high energy demand and has a potential to increase its use of solar energy. In this study different energy solutions for solar energy use in multifamily residential buildings was examined. To meet the difference in solar energy production and energy use some options for energy storage were investigated. Seasonal storage of solar energy enables solar heat from the summer to be used during the winter. Simulations were made of a existing multifamily residential building from 1950 owned by the housing company Uppsalahem in the city of Uppsala. Different combinations of solar panels, solar thermal collectors and geothermal energy, which originates from solar energy, were dimensioned to decrease the amount of bought heatand electricity, and at the same time be economically defensible. Energy storage in the form of battery storage, heat storage in a combination with district heating system, and heat storage in the bedrock were investigated. The results showed that none of the systems were profitable except for a system with only solar panels. Two systems with geothermal energy in combination with solar panels or solar thermal collectors met the Swedish National Board of Housing, Building and Planning's demands of energy requirement for a newly built multifamily residential building.
