Passivhaus Certification

Quality assurance

Passivhaus Certification is a quality assurance process for the design and construction of low energy buildings. It is independent and neutral with the Certifier representing the best interests of the building and building owners, now and in the future.

Catching mistakes

Quality assurance accepts that everyone makes mistakes and looks to catch these early through checking. Small changes and errors can have a big impact on the performance of the building in use.

Better buildings

Contributing to better buildings through construction advice, training, and sharing extensive experience between projects. Proven to work through feedback and monitoring.
