PVT Meets Historic Preservation – Energy-efficient Refurbishment of an Old Mansion in Chemnitz, Saxony

Project Challenges:

  • Replacement for fossil fuel heating (gas heating) required
  • Architecturally challenging roof construction with dormers
  • Listed building requirements due to slate roofing

Solution with Sunmaxx PVT:

  • Switch to renewable heat supply with PVT and brine-water heat pump
  • Use of available roof space for electricity and heat generation with 80% overall efficiency
  • Use of standardized PV substructure (“Sunmaxx: the PVT module with PV mounting technology”)

Heat and Electricity for Multiple Residential Units – Cleverly Combined with a Brine-to-water Heat Pump and Ground Collectors

In Chemnitz, there is an elegant old mansion whose roof has been converted into a dual energy source. Despite its steep slope, numerous dormers, and slate roofing, there was enough space for 22 PVT modules from Sunmaxx – all of which are historically appropriate, powerful, and visually appealing. The result: a climate-friendly energy supply that combines tradition and innovation.

PVT Combined with Seasonal Storage Technology for Maximum Efficiency

The PVT system reliably supplies the city villa with heat and electricity. The system is supported by ground collectors, which serve as seasonal heat storage units and make year-round operation even more efficient. The result is a renewable energy system that covers the entire heating requirements of the apartment building from renewable sources – quietly, sustainably, and with a secure future.
