A Passive House is far more than the sum of its parts: precise planning is required in order to ensure that the components used work together to achieve the desired result. Two pieces of software define the Passive House design process.

  • The Passive House Planning Package (PHPP) is the key design tool used when planning a Passive House and as such, serves as the basis of verification for the Passive House Standard. While there are other design tools on the market, it is the the PHPP’s high level of accuracy that sets it apart: energy balances can be calculated with the PHPP to an accuracy of +/- 0.5kWh!
  • The new designPH plugin has been developed by the Passive House Institute to provide a 3D model interface for entering building geometry into PHPP. The benefits of the tool are two-fold; firstly it will simplify the process of entering data into PHPP and secondly it will provide preliminary feedback on the performance of the design within SketchUp.
