This Guide is intended to supplement to the "Criteria for the Passive House, EnerPHit and PHI Low Energy Building Standards" ("Criteria") published by the Passive House Institute and posted online. It explains the Criteria's requirements given here in a brief and precise manner.

Sections one and two of this guide are aimed at building professionals and building owners who are interested in energy efficient construction and renovation. They present the energy standards of the Passive House Institute and explain the advantages and process of building certification.

The third section serves the Designers and Consultants as an aid in the certification process. It explains clearly what is meant by the precise requirements in the certification Criteria and what types of documents can be submitted as proof. However, the Guide does not replace the Criteria published on the website of the Passive House Institute. These remain the legally valid definition of the Passive House and EnerPHit Standards.
