The independent institute for maximum energy efficiency in buildings
Welcome to our website!
Energy-efficient buildings are essential for effective climate protection. They guarantee maximum living comfort, good air quality, and low energy bills. The building standards Passive House and EnerPHit retrofit present proven, cost-effective and reliable solutions for achieving outstanding energy efficiency in buildings.
For more than three decades, the Passive House Institute has been one of the leading independent research institutions in the field of highly energy-efficient construction and retrofits. In addition to our research activities, we offer comprehensive advice on efficiency measures and project support, train specialists, certify energy-efficient buildings and building components, develop planning tools and advocate for Passive House principles in policy, media, and across the construction industry.
Innovative solutions for the installation of new windows in retrofits
Passive House visitors: Experience Passive House for yourself!
Two new EnerPHit brochures created in the EU-funded "outPHit" project (free download)
