Solar
This building underwent an energy-efficient renovation. New insulation and windows reduced energy consumption by 60%. The remaining heating demand in the historic building is met by a heat pump from CTC. The heat pump features an excellent COP of 4.4, a high flow temperature and a modulating output of between 4 and 22kW. Most of the electricity required is generated by the new photovoltaic system. A 12kWh battery storage system with backup power functionality and a 1,000-litre hygienic thermal store retain surplus energy from the photovoltaic system for times when the sun is not shining. This covers 70% of the building's energy needs (electricity and heating). Combined with the savings achieved through modernisation, this amounts to a total saving of approximately 90%.
