What is PHPP?
The Passive House Planning Package (PHPP) is a powerful design tool used for designing high-performing buildings, such as those that meet the Passive House standard. Based within Microsoft Excel, PHPP is a 2D tool that produces far faster results than 3D modelling software while delivering an accuracy rate of 95 percent. This makes it an ideal application for economically optimising designs.
PHPP is required for use in Passive House design and by Passive House building certifiers. It is useful at all stages of the design and planning process, as levels of detail can be slowly built up. At its most basic level, PHPP is a quality-check tool which applies factors to your project such as the laws of physics, geo-location data and the local climate. Because the tool is based on well-established scientific theory, the results produced are a close reflection of reality and can be used to make decisions around performance, sustainability, and economics.
