This thesis aims to examine the potential to optimize the energyusage of a building by implementing a controller that considerweather forecasts in the surrounding area.By 2040 Sweden aims to achieve 100% renewable energy production. Inaddition to implementing renewable production sources to reach thisgoal, there is a need for increased efficiency in both power andenergy consumption.Weather forecast control as a concept is designed to optimize theenergy usage of a building and thus making it more efficient. Bybuilding a weather forecast control in MATLAB and modeling abuilding in IDA Indoor Climate and Energy, the effects of thecontroller could be examined. To evaluate how the control effectsthe building and which potential there is to optimize the building,two parameters where chosen for evaluation. The parameters were howthe energy use was affected by implementing the weather forecastcontrol in the building and what potential there was to improve andchange the load profile of the building to avoid power peaks.It was found that by implementing the weather control, the energyusage of the building decreased by about 15%. On the other hand,the potential to avoid power peaks in the building was foundlimited. This limitation was because of the strong effects coldtemperatures had on the building. In conclusion, it can be statedthat a weather forecast control can be considered a goodalternative for projects focusing on energy efficiency. However,its ability to affect power peaks should be considered limited.
