Energy Efficiency and Solar Energy in Student Housing (English)
Abstract [sv]

Uppsalahem AB is a municipally owned real estate concern that owns and administrates housing for nearly 30 000 people. The company puts a lot of effort into reducing the energy use of their housing stock. This project is a master’s thesis in the energy systems programme at Uppsala University, carried out in collaboration with Uppsalahem. The aim of this thesis is to provide energy saving measures for fourteen student housing buildings in Uppsala, Sweden. The buildings contain 467 flats with an area of 10499 m2.

The buildings have been modelled using the computer software VIP-Energy and the results have been validated by comparison with the actual energy use. Different measures on the building envelope and ventilation system have been evaluated. Measures include refurbishment and/or exchange of the current windows, insulation of the buildings facades and cellar walls and upgrading the ventilation systems to recover heat. Alternatives for solar electricity and heat generation have also been presented.

Results show that both solar heat and electricity can be economically viable. The viability of the solar electricity alternatives are dependent on governmental subsidies, the system being grid connected and the possibility to sell surplus energy. Furthermore the simulations of building envelope and ventilation measures show a technical possibility to reduce the total amount of purchased energy for the 14 buildings by 50 %. Window refurbishment also shows potential for economic viability, however; further studies will need to be carried out on maintenance costs and current window status.
