Abstract

The necessity to transition to a net zero economy has led to legislation that seeks to fully decarbonise the building stock in the European Union by 2050. The aim of this study is to investigate various strategies for utilising the thermal mass of a building to reduce its energy costs while ensuring the occupants' comfort in a first-of-its-kind multi-apartment positive energy building located in a Nordic climate. The findings of this simulation-based study suggest that a combined storage-conservation strategy, with a heating setpoint of 21.5°C during low energy price periods and 19°C during high energy price periods, results in the highest cost savings. Furthermore, this study highlights the importance of using such controllers in the current high and fluctuating energy prices scenario.
