Energy performance and scenario analyses of a multistorey apartment building in Norway

Plus Energy Buildings are perceived as a strategy in the energy transition and to promote decarbonization of the building stock. This paper presents the design development of a plus energy demonstration project based on building performance simulations performed with IDA-ICE for energy strategies and future scenarios. The objective of the design strategies was to reduce the primary energy consumption, while ensuring a satisfactory indoor environment. Future scenarios for climate change, user behavior, and energy flexibility were developed to analyze the impact on the building's energy performance. Results from the analyses reveal the expected building performance with respect to energy and indoor environment standards, and robustness with respect to meeting the standards under different scenarios for occupant behavior and climate conditions. According to the simulation results, the building design is robust and can adapt to changes in exterior conditions.
