Indoor thermal comfort and associated adaptive measures towards an energy efficient new campus in Borlänge, Sweden

Margelou, Dimitra January 2020 (has links)
Thermal comfort of the occupants is of highest importance specifically in Scandinavian countries. Especially for an educational building, both students and working staff spend most of their time indoors, therefore it is critical to guarantee a healthy and productive indoor climate environment around a whole year. Taking into account that Högskolan Dalarna plans to move into a newly renovated building in the center of Borlänge in 2022, this thesis focus on this essential topic and tries to dig out some valuable adaptive suggestions for the coming schematic design phase. In the next design phase, it aims to satisfy design requirements of Miljöbyggnad 3.0 certification at sliver level, as well as operation requirements of BREEAM InUse at very good level. Consequently, the aim of this thesis project is to have an overall thermal comfort assessment of all representative rooms in the project of the new campus building in Borlänge, Sweden. The thermal comfort assessment consists of both winter situation and summer situation. Both situations are completely under recommended study method from Miljöbyggnad 3.0 with the technical assistant of dynamic building simulation software tool IDA ICE 4.8. Several aspects have been investigated in terms of indoor thermal comfort. The first impacting element is future climate scenarios, so as to check how the future climate will affect the thermal comfort performance. Afterwards, both external and internal shading devices were individually applied to examine and quantify the benefits in terms of indoor thermal comfort. Lastly, the advanced control shading strategies were studied to further improve the thermal comfort performance based on the appropriate conventional shading method. The results showed that future climate scenario has limited impact on the thermal comfort performance when rooms are under temperature controlled via room heating and cooling units. Regarding the shading methods, the internal shading was proved to give a better overall performance. If there is the chance to implement automation shading device, the author recommends the “zone air temperature with operative temperature setpoint 21°C, in which proved to be significantly improved the thermal comfort levels that previously discovered in the vulnerable zones. Therefore, it is expected significantly to reduce the energy dependency during cooling season.
