High-Performance Project Planning Pack

The #1 cause of budget overruns is rushing to the design phase before completing research and analysis. This is like a doctor rushing a patient to surgery without a proper diagnosis. An out of control project is stressful, expensive and unnecessary.

The solution is successful planning. This is why we created the High-Performance Project Planning Pack.

PHPP: System requirements and license type
The PHPP is based on an 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 (PHI) 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 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 updates of the calculation tool, or upgrade discounts for new versions of PHPP or designPH.
designPH: 3D data entry tool for the PHPP
designPH is a plugin for the well-known 3d modelling software SketchUP. You can model your project in SketchUP (or import it from other CAD software) to have a 3D display of the building envelope. Passive House certified components such as windows are directly available as SketchUP components within the software. The plugin carries out automatic analysis and simplified calculation of the heating demand which is reported in a Passive House dashboard within SketchUP. You can carry out 3D editing and optimisation of the building design while simultaneously keeping track of the performance. The building envelope geometry along with windows and shading data can be exported to the PHPP. Further details can be found at along with designPH system requirements.

For more detailed information about the PHPP software, please visit the Passive House Institute’s PHPP page.
