Energieffektivisering i sambandmed renovering
? Analysmodell för energibesparande åtgärderutifrån ett företagsekonomiskt perspektiv
Rising energy prices and higher energy demands have led to an increased focus on energy efficiency, in particular in the real estate business, where high potential for energy savings exists. Within the next few years, buildings that were constructed in the sixties and seventies will be in need of renovation. One of the challenges of these renovations will be to improve energy efficiency. A real estate company that is facing this challenge is Uppsalahem AB, based in the city of Uppsala, Sweden. This study focused on analyzing energy efficiency measures when renovating old buildings. An analytical model for improving efficiency from a business perspective was compiled. The model describes how an analysis of energy efficiency measures can be conducted to determine if the measures meet established energy goals. The model is Excel-based and contains the steps of collecting data, calculating energy use, actions to mitigate inefficiencies and analysis.To develop an analytical model, a case study was selected and analyzed. Through this work, conclusions were drawn about how energy efficiency analysis should be performed. Several methods were compared and the most suitable methods were chosen for future analysis.
