The Passive House Planning Package (or PHPP) is the detailed calculations tool for designing Passive Houses,  consisting of an Excel spreadsheet workbook and a manual. The PHPP provides everything needed to design a properly functioning Passive House including tools for:

  • calculating energy balances (including U-value calculation)
  • planning the windows
  • designing the comfort ventilation system
  • determining the heating load
  • estimating the summer comfort
  • design the heating and hot water supply

It also provides a variety of other useful tools for the reliable designing of Passive Houses as well as:

  • verification for Passive House funding (e.g. for low-interest loans available in many countries)
  • a simplified verification method (based on the German Energy Saving Ordinance)
  • a detailed handbook that provides not only a detailed explanation of the PHPP calculation method but also important details for the construction of Passive Houses – the Passive House construction manual par excellence.
  • an example project (residential building) calculated in the PHPP

PHPP version 7 (2012) is now available. For more information and to order, visit the PHI website.
