Easy to use software to help with PHPP calculations.  The UK version of PHribbon is developed exclusively for the AECB.

AECB PHribbon makes using PHPP quicker, easier and it uses the existing information beyond just energy. It’s written by Tim Martel who has worked as a Certified Passivhaus Designer for 10 years, formerly a Chartered Architectural Technologist, a course tutor for the AECB CarbonLite™ Retrofit Foundation course, and AECB software R&D lead and developer.

This is the Costings add-on to PHribbon.  You must own a copy of PHribbon before purchasing this product.

PHribbon is now able to calculate an Improvement Option Evaluation required for retrofits under PAS2035.  PHribbon automates the process so that you can find suitable measures for your retrofit, either using Simple Payback or Carbon Cost Effectiveness (£/tonne of CO2 saved).  Click here for more information and see the tab below for an example of the data output.

The technical specifications

PHribbon uses Microsoft Excel as a base.  No special PHPP is needed. PHribbon is compatible with PHPP v10.

Minimum Requirements :

  • a Windows (PC) computer. If you have a Mac you will need to run a PC emulator (it works with Parallels, VMware fusion 11 with the PC version of Excel installed)
  • Microsoft Office 2010 or later, the full installed version not the website version (an option in Office 365)
  • Access to Dropbox for installation and also for updates. This can be from the Dropbox website, though installing the software (free) is quicker and easier
  • A recent version of PHPP: 10, 9.6, 9.3, 9.1, 8.5 or in the US the imperial version 9.7IP. Using the latest version is recommended so that you have an accurate PHPP.

By using this software you agree to these terms :

  • Users may not redistribute the PHribbon spreadsheet, or repackage it free of charge or otherwise.
  • The software has been rigorously tested and great care has been taken to ensure there are no errors, however not every situation in which PHPP can be used can be foreseen, therefore checks for costs are still recommended. Any mistakes found will be corrected free of charge and all users updated. The user is responsible for checking the figures, especially in circumstances where they are critical. In extreme circumstances the maximum compensation will be a refund of the price paid for the software. By using this software you agree that no legal claim can be made against the AECB nor Tim Martel.
  • Costs provided are indicative only and are the best information available to the author. By their very nature they are variable according to location, supplier and quantity. They serve only as a starting point and can be updated at any time either for one project (i.e. changing the figure in the costs tab in the PHPP) or by changing the master table for all future projects in the PHribbon spreadsheet.
