The Passivhaus Institut (PHI) has developed a Trimble Sketchup plugin tool to ease the process of building geometry input into the PHPP. The designPH tool will allow users to model their Passivhaus projects in 3D using Sketchup, and then import the data from the model into the excel tool.

For those who have gone through the often painful and potentially error-ridden task of entering building geometry into the PHPP, this may come as a welcome relief. The ability to visualise the design in Sketchup, with the preliminary feedback and analysis this allows, as well as the simplification of entering data into the PHPP may prove invaluable to many building designers. designPH will provide a variety of useful features including:

  • The ability to work with a new or existing Sketchup model (some simplifications may be required);
  • Automatic recognition of temperature zones, element types and area groups;
  • Schedules of areas, windows/doors and TFA components as well as recognition of external shading objects;
  • Rendering of heat-loss areas to indicate their area group or status;
  • Export geometry and shading data to PHPP via a PPP file, with conversion of elements to meaningful dimensions and quantities that can be manipulated in PHPP;
  • Tools to insert and edit window and door components, either with user-defined properties or from standard libraries;
  • Simple energy balances within the tool along with warnings as to high-levels of glazing that could lead to overheating.

The new designPH modelling tool will be released together with the English PHPP 8 in summer 2013. More information on designPH can be found on Passipedia.
