Passive houses

From single-family homes to office complexes

We lead the pack

Whether for the energy-efficient renovation of the first passive high-rise building in the world or the construction of the largest urban district that complies with the passive house standard – REHAU was there. Learn more about these projects – the Buggi 50 in Freiburg or the city gate at Heidelberg Bahnstadt – in our references.


Our products for passive and energy-plus buildings
From geothermal energy systems to sub-surface heating and windows – our systems ensure a comfortable indoor climate in passive houses:

  • GENEO windows without thermal bridges with a Uf value of 0.79 W/m²K and up to 76% energy savings, which, without reinforcements, ensure additional solar energy gains even for large glass surfaces.
  • RAUTHERM sub-surface heating and cooling for an optimum indoor climate with no drafts or operating noise. Ideal for renovated properties thanks to the drywall construction.
  • RAUGEO geothermal probes as an energy source combined with our AWADUKT Thermo air/geothermal heat-exchange system ensure controlled ventilation without microbial contamination.
