Lönsam energieffektivisering : Ett samarbete mellan ÅF och kund

This thesis project has focused on studying ÅF’s business concept Energy Collaboration, which is their way of selling energy efficiency services. Thereforeongoing projects have been analyzed. The purpose was to determine achieved energy efficiency, costs and profitability for the studied projects. It was concluded that the Energy Collaboration is a good way of selling energy efficiency services, since the customer takes no risk and energy savings of about 15-25 % can be achieved with simple measures. ÅF’s costs for binding capital in projects were calculated and the result showed that it is possible for ÅF to use this concept and still make a good profit. However, it is important not to run too many measures at the same time, since it will result in lower profitability for ÅF. The thesis did also include two studies of energy efficient measures. The first one dealt with how to install an air/water heat pump to lower a building’s use of energy.This was carried out through simulation. Therefore, a code in MATLAB was written for this purpose, and this model was used to evaluate the potential energy savings from the heat pump installation. An existing dimensioning program from NIBE was also used for comparison. The results showed that a district heating price of 0.80SEK/kWh is needed in order for this measure to become profitable. The second study was about presence control of lighting in a museum that was part of an ongoing Energy Collaboration. The study was done mostly in theory, except foran inventory of the current building, and potential energy efficiency and costs were calculated. The results showed that it is profitable to realize this measure in the Energy Collaboration, and the most profitable solution is to wait for all the older measures to be paid off before the presence control installation is carried out.
