Abstract [en]

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations. To calculate the loss of energy a u-value was used, which describes a materials ability to conduct heat. The results of the energy calculations show what is reasonable to do in the building considering the energy savings versus economy. The study shows that it is important to first analyze and adjust the building envelope and ventilation before a new heating system is installed. That is to reduce the risk of an over-sizing of the heating system. It is not optimal to correct the entire building at energy efficiency because it is not economically feasible. All necessary actions of energy saving should be taken as a package where the most profitable should be picked out and executed. An older building is often of great value and therefore its appearance should be safeguarded at energy efficiency.
