Analysis of the reduction of the energy demand of a house by using a glass structure

Abstract: This study focuses on the effects that a greenhouse can have in the energy demand of a regular Swedish dwelling. Based on the layouts and information that Fiskarhedenvillan house constructor company supplied, a simulation model was built on IDA ICE and a greenhouse was placed attached to the house. The results show an energy reduction of 12 % in heating by placing a greenhouse next to the house in the south façade, as well as the possibility to use the space for growing plants. An analysis about the change in the orientation of the house was done in which it was proved that south orientation implies the lowest energy demand. Lastly, the possibility of installing a heater in the greenhouse was studied by making an energy analysis of it, in order to consider the chance to use the greenhouse as another common area all over the year.
