Abstract [en]

On behalf of GATE Intelligent Support AB an energy audit has been conducted in the spring of 2015. The project was to develop an energy audit at an industrial premise in Vännäs municipality. Vännäs Fastigheter AB is the owner of this venue and has recently received complaints from tenants about an cold indoor climate in the property. Furthermore, it emerged that the property's future energy supply of heating is uncertain. Therefore a separate project to find an alternative heating sources solution has been initialized. This report will place great emphasis on changes, which lead to an improved indoor climate as to energy savings. To achieve this plan and to make it more understandable the simulation program IDA ICE has been used throughout the whole paper. Additionally, economic calculations for an LCC-analysis including repayment time has been done to compare the measures easier. Results from this project have demonstrated that this industrial premise can when all energy saving measures are carried out, reduce their energy consumption from 299 MWh per year to 129 MWh per year. This means a total decrease of 56.9%. The inspection of the property reveals shortcomings in the existing heating system. The current radiator system was configured wrong which resulted in a significant reduction of the heat outcome. This was not just done by changing settings of the radiator system but as well by adjusting the ventilationsystem to the business conditions of the property.
