From TEK17 to ZEB-O – A case study for a residential building in northern Norway

Abstract

With a strong focus on reducing emissions from the building sector, it is important that new buildings can compensate for emissions caused during their operation by on-site renewable electricity generation. In academia, there is consensus on measures to achieve a so-called zero emission balance, but there are still mostly pilot projects that have a focus on emission analysis during the planning process of buildings. This work is associated to the Sjøsiden project of Gunvald Johansen Bygg AS, a local entrepreneur in the city of Bodø (Northern Norway). The main goal of this study is to assess the most suitable energy system for the Sjøsiden project in order to approach a zero emission balance, taking into consideration the local conditions in Northern Norway. Three different energy systems are analysed for this project using the dynamic building performance simulation tool IDA ICE, Version 4.8. This work confirms previous findings that a building with passive house standard equipped with a heat pump and photovoltaic panels gets closest to achieving a zero emission balance. In the end, practical implications for zero emission buildings are discussed.
