<p>The heating of companies premises is today functional with electrical heating and heating of</p><p>fossil fuel. The energy cost for these kinds of heating in buildings has heavily increased during</p><p>the last years and the influence on the environment has become more visual. This leads to that</p><p>enterprises today become more anxious to render energy more effective and find alternative</p><p>solutions to their ancient heating systems. This is something that Skandinaviska kraftprodukter</p><p>AB in Halmstad has become aware of.</p><p>The purpose with this examination is to find the most cost-efficient and environmental measures</p><p>for the office and workshop premises of SKP AB. Where one of the bigger things is to find a</p><p>good alternative for their current oil furnace, which was heating the workshop. Another big thing</p><p>was to take forward suggestions for measures of rendering energy more effective for the</p><p>buildings. By taking contact with people in the business and by inspecting the premises and the</p><p>heating system, we got an idea about the measures that could be of current interest. We analysed</p><p>these measures to see if they could last financially and environmentally. At the financial analysis</p><p>we used LCC-method which means that you calculate the cost of the investment during its life.</p><p>With the heating system this means, among other things, running, maintenance and initial costs.</p><p>To examine the affect on the environment from the different heating alternatives we chose to</p><p>make a easier LCA, which we based on the local conditions.</p><p>In an existing building it is the simple measures of rendering energy that dominates financially,</p><p>the bigger investments don’t create financial expectations high enough with the energy prices of</p><p>today. In the workshop it was foremost a number of industrial gates that led to great heating</p><p>losses, which would best be taken care off by PVC-stripes curtain or automatic shutoff of the</p><p>heating system when the gates are open. Another alternative would be to invest in aircurtain. This</p><p>would reduce the heating losses a lot, but because of the large investment cost is this not an</p><p>option. The most cost-efficient measure is to increase the awareness of the employees, about how</p><p>their behaviour is affecting the use of energy and to make sure that heat and ventilation doesn’t</p><p>run unnecessarily.</p><p>While going through possible heating alternatives for the workshop, three alternatives seemed the</p><p>most interesting, air-to-air heat pump district heating and pellets. When it came to the financial</p><p>aspects where there no great difference between the three alternatives, when you looked at a</p><p>calculation period over 30 years. Environmentally heat pump was the best choice because the</p><p>electricity of HEM is water produced. The district heating had the highest affect on the</p><p>environment because it partially comes from waste burning, which leads to large emissions. From</p><p>comfort and maintenance point of view we think that the district heating is the best alternative for</p><p>the enterprise, foremost because you don’t have to maintain the system and it can heat the</p><p>premises even during the coldest days. The downside with pellets is that it brings a curtain</p><p>amount of maintenance and that pellets storage takes a lot of place. The downside of heat pump is</p><p>that it doesn’t have enough effect to cope with the coldest days.</p><p>Our recommendation of heating system is district heating. It is true it has the biggest influence on</p><p>the environment but because it can handle the need for heat during all parts of the year and that it</p><p>is free of maintenance ways up for its influence on the environment.</p>
