PHPP + designPH + PHribbon

The PHPP allows users to create a complete building model to determine the energy performance of both the whole building and its individual elements.  The impact of design changes is instantly displayed, enabling designers to efficiently rule out non-compliant designs and optimize the building performance.

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, layout 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

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. As far as the authors are aware, the PHPP can also be used with current versions of OpenOffice or LibreOffice, on Linux systems, and on Macintosh computers. However, depending on the platforms used and their programming, there may be limited functionality of the calculation tool or the macros of the additional tool.

The PHPP is sophisticated software that requires careful data input to ensure accurate results. It is highly recommended to enrol in the Understanding & Working with PHPP course to learn how to properly use the software. Experience has shown that individuals who have taken no or limited training (e.g. 1 day) struggle to correctly model buildings.
