Systemic Heat Shift connects city-owned buildings to intelligent heating control operated by the city's energy company — reducing energy consumption and CO₂ emissions by avoiding overheating and using connected buildings as a "virtual heat battery" that provides flexibility to the district heating system. Year 1: A secure IT connection was established between the energy company's control system and the city's internal network, and the first pilot building was integrated. But developing an optimisation algorithm for educational buildings proved more challenging than anticipated. Sports arenas were removed from scope entirely. Personnel changes further slowed progress.
