PHPP – Passive House Planning Package
The PHPP is a sophisticated design tool specifically developed by the PHI for the accurate planning and calculation of Passive House buildings. The PHPP is similar to SAP however, PHPP is considerably more advanced, with the ability to provide accurate results that have been proven through extensive monitoring of existing Passive House buildings across Europe.
The PHPP software is an excel based programme that has been developed by the Passive House Institute via the PHPP development group over the course of 15 years. The software was originally invented in 1988 to test and verify the results of the first Passive House building completed in 1989 in Darmstadt Germany.
The software is intended as both a calculation and design tool that should be used through-out a project to improve and inform product and material choices as well as overall design decisions.
