Study of heat flows in existing housing estate : Evaluation of energy efficiency measures (English)
Abstract [en]

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.

The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974. Evaluated measures are among others, addition of insulation, installation of windows with a higher energy performance and installation of different ventilation systems.

The results show that measures such as addition of insulation to ceilings are profitable solutions, which is also the case for installation of windows with a better energy performance, provided the old windows, which are going to be replaced, are in poor condition. Furthermore, the results show there are a couple of options for energy production and the board of the residential estate therefore have to decide which type of heating energy system they prefer for the future.
