Energikartläggning och energieffektivisering av flerbostadshus : Utredning av möjliga energibesparande åtgärdsplaner i området Oxhagen, Örebro.

Sammanfattning: The purpose of this report is to investigate how Örebrobostäder (ÖBO) can decrease their energy use in the residential area of Oxhagen. Oxhagen is as mentioned a residential area located west from Örebro center and have about 690 apartments in different sizes. ÖBO needs to do this survey because they obey from the law of energy mapping in large companies, this law is produced from the EU directive, energy efficiency directive with its purpose to reduce the energy using in the country so the imported energy decreases. Energy statistics have been handed from ÖBO, this energy data has been analyzed and the data have been put in respective calculations, using Excel. Also, a model of a real estate has been made in the simulation program IDA ICE, in this simulation program energy calculations are made. There has also been a technical inspection of the reference real estate. The result shows that the biggest decrease in energy will happen with a decrease in the heating of the building. It also shows that a change of windows can reduce energy use significantly. Therefor the conclusion is that a combination of heat decrease, and window change can make an enormous difference in energy using for the reference real estate and the combination can also apply on other real estate in the area Oxhagen.
