Franziskus Hospital Hardberg

For the facility team of the Franziskus-Hospital Harderberg, the following main goals were important regarding the decision in possible investments in the energy supply system: 1) Safe Energy Supply. 2) Local energy production should be based on local energy demand profiles (high self-consumption coverage). 3) Stable and predictable mid-term and long-term energy rates. 4) No interruption of the existing operations. After detailed due diligence of possible energy solutions, the hospital decided to install a solar thermal system, fulfilling the goals in the best way. The system, with a gross collector area of 790 m²/8,500 ft², produces 320 MWh per year. Depending on the available solar energy and energy demand, the plant can support the domestic hot water, heating, and air-conditioning system. Should there be any surplus heat left – no problem – the system can feed into the existing heating grid too. The perfect green energy supply mix!
