Abstract [en]

This report is of technical character and treats how to plan a small building in Borlänge, Sweden.

The technical components that have been treated in the report are the construction, foundation,

installations and thermic abilities of the house. In addition to planning this house the report also

contains a part that deepens in net zero energy buildings. The purpose of the report is to

investigate if the house in Borlänge can be constructed to meet net zero energy building


Energy efficient houses such as passive- and net zero energy houses are showing more frequent

on the market in Sweden. Ongoing climate changes and growing consciousness about the

environment in society have contributed to that the environment is a well discussed topic. To

consume small amounts of energy and at the same time produce local energy is therefore

something that lies in the future and future houses. Production of local and environmental

friendly energy is a great challenge and demands significant knowledge. In this report we have

aimed the focus on environmental friendly sources of energy such as sun energy, wind power and

biomass of pellets. Based on knowledge from our earlier studies within our programme we have

investigated the possibility of planning a net zero house in Borlänge.

It turns out to be difficult to plan a net zero energy house in Borlänge. The research shows that

the planned house does not pass the demands for a passive house and therefore it does not pass

the net zero energy demand either. The planned house has a high shape factor which indicates

that a significant amount of internal heat passes through the climate shell. To meet the passive

house demands we would have to give the house a different shape to obtain a lower shape factor

which would increase the ability of the house to keep internal heat. Because of the fact that

Borlänge is situated in climate zone II in Sweden it needs heating during main part of the year. In

addition to this there are few hours of sun during the winter and the conditions to create energy

from wind power are relatively poor. Due to this it is difficult to produce more energy than the

house will consume.
