Simulering av värmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt värmesystem

Sammanfattning: In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built. The energy needed for the heating of the building was simulated using VIP+. The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency. Just adding more insulation is not sufficient but in combination with other proposed improvals it makes it possible to reach the target.
