Energy Savings
As part of the renovation, the heating circuit distributor and pump technology were replaced, and a new ventilation system with integrated heat recovery technology was installed. The pipework was also upgraded from a single-pipe to a double-pipe system. The final energy requirement for room heating, hot water and ventilation dropped by 65% as a result. The primary energy requirement, meanwhile, fell by more than 75% to 47.0 kWh/m2a.
