Anybody can build a Passive House, because the standard is not trademarked. But how can you check that a building is a real Passive House? And how to be sure that it will perform as planned and deliver its promises?

Well, ask for third-party quality assurance! That is our main job as an independant research institute. Beside research projects and software development, we are certifying Passive House professionals, suitable components and assessing the performance of buildings worldwide.

Do you want a Passive House building? Then your project team should contact the closest PH designer or consultant. He will guide you right from the start, when changes are easy to make and cost-efficient solutions can be found.

They will plan and optimize your project with PHPP and designPH. These tools are continuously being improved thanks to monitoring data and dynamic simulation. The energy demand calculated with PHPP is very close to the measured consumption detected in monitoring projects. The more efficient the building, the lower the deviations.

During the design process, your team will select high quality components according to the local climate.

But the best design is worthless without top quality construction work. Certified Passive House tradespeople will ensure energy efficiency targets are met.

Hang on, we are almost there! Now a PH certifier will check the PHPP, design documents and building site records to ensure the Passive House criteria are met. The Passive House international criteria are defined numerical values, which are based on the laws of physics. If all criteria are met both in PHPP and on the building site, then your building can be certified!

Once the building is certified, residents can peacefully move in and enjoy their new quality of life. Be it in a new building or in a retrofitted one, they will experience similar benefits!
