Energikartläggning av en äldre fastighet : En kartläggning kring energiförbrukningen och kostnadsbesparande lösningar för en äldre fastighet

Sammanfattning: On the behalf of Norrporten in Umeå have an energy audit been made on an older part of a building. The goal has been to calculate the distribution of energy carriers in the property and to find out what the operating cost for the building is. With that in mind so have different methods to reduce energy and operating costs been examined and its effect on energy consumption. This survey analyzes ventilation, heating, water heating and climate shell of the property. Measures to reduce energy consumption due to operations in the building have not been examined. The simulation program IDA ICE was used for energy calculations. The results show that the property currently use about 150 MWh/year of heat and about 104 MWh/year of electricity. This means an annual operating cost of about 200 600 SEK. Among the largest energy consuming parts are: Heating of the facility Heating of domestic hot water Ventilating el for fan operation The total savings opportunity is apparent to about 14,600 kWh/year of electricity and about 39,600 kWh/year of district heating.
