The Passive House Planning Package (PHPP) is the building energy modelling software used to design a Passive House building. It is an essential part of the building design process.
The PHPP is an easy to use planning tool for energy efficiency for the use of architects and planning experts. The reliability of the calculation results and ease of use of this planning tool has already been experienced by several thousand users.
The PHPP enables the building designer to:
- Determine the most suitable form of the building and the impact of design choices on energy efficiency
- Calculate the required performance level of individual components such as wall insulation, windows, etc. and their influence on the energy balance of the building in winter and in summer
- Calculate the heating and cooling load
- Determine the size and required performance of mechanical systems
- Calculate energy production from onsite renewables and the building energy needs being met by those renewables
- Calculate the life-cycle costs of different design options
- Confirm whether the building meets the Passive House certification criteria
The PHPP has been thoroughly validated against measured performance data of real buildings in various climates, so you can be assured that the energy demand it predicts will reflect actual energy consumption.

System requirements and license type
The PHPP is based on a MS Excel workbook in the xlsx/xlsm format. Microsoft Windows XP (or higher) and Microsoft Excel 2007 (or higher) are system requirements. On Macintosh, PHPP works with Excel for Mac 2011 (or higher). As far as the authors are aware, the PHPP can also be used with current versions of OpenOffice or LibreOffice. However, depending on the platforms used and their programming, there may be limited functionality of the calculation tool or the implemented macro tools.
PHPP is only provided as single-user license, including a detailed online flip-book manual. With the license the PHPP user obtains a registration code which is used to register the PHPP license. Based on this registration, the user will receive access to the download of PHPP, the online flip-book manual, and to updates of the calculation tool, or upgrade discounts for new versions of PHPP or designPH. An option to purchase the printed manual is also available.
