Abstract [en]

The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.

This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.

Studies and analyses on energy consumption and moisture transportation were made. Both calculations by hand and computer simulations were part of these analyses. The effects of different materials on the functionality of the building envelope were analyzed.   

The main point of this project was to see if the present designs were satisfactory with regard to the mentioned requirements, and what changes were possible to make and should be done.

These analyses show that the two buildings, with coherent constructions, did not correspond to the individual goals that had been set by the companies. One of the results shows that the calculated mean heat transfer coefficient did not match the goal set for the corresponding building. Some changes that should be made on its insulating performance are presented. 

This report concludes that the evaluation of a building envelope, by all relevant factors, is a difficult task (there are too many variables to take into account). On the other hand it is possible to get an overview of its performance in a simple way. Which is done by following the methods presented in this report.
