Sammanfattning
This thesis investigates how to lower the energy demand of a residential building located in a temperate climate of Kungsbacka, south of Sweden.
To get an understanding of the relevance of passive design strategies and the possibilities, literature research is conducted. Relevant topics are explained such as thermal comfort, passive house and bioclimatic design. Furthermore, built examples that can relate to the climate of Kungsbacka are shown as references.
The design strategies will in addition to the literature research be evaluated through simulations in IDA ICE which is a simulation software that is used to simulate thermal comfort in a building. The simulations tempt to give an understanding on how to use the passive design strategies in a suitable way according to the local climate. This is important since the relevance of different passive design strategies differ depending on which climate the building will be built in.
The results of the simulations shows that due to the conditions of the chosen site Söderbro 10, all except one of the chosen passive design strategies is suitable. The excluded one was thermal inertia which was found to have little impact on the energy demand. This was resimulated and found to be more suitable on wooden floors than concrete. A dense and well insulated building envelope is important, and to use the sun as an energy source. This is possible at Söderbro 10 since the site does not have any buildings that block the solar radiation from the south. An angling of the design proposal towards the street allows for better conditions for solar radiation.
The conclusion shows how integrating passive design strategies can reduce the energy consumption by 15%. The work provides a good basis for the understanding of how passive design strategies can be applied in a local context and highlights the importance of deeper study of aspects such as life cycle analysis, economy and values, and settings for simulation.
