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, Certified Passivhaus Designer, Chartered Architectural Technologist, course tutor for the AECB CarbonLite™ Retrofit Foundation course, AECB software R&D lead and developer.
PHribbon enables you to build the PHPP faster and the CO2 calculations benefit designers, consultants and clients by making it an easier, quicker process. The latest version of PHribbon gives the carbon impact of materials before they are selected and the impact of substitution of materials can be quickly seen.
This AECB software contributes something that has not been done before. There are embodied carbon calculations and tools elsewhere in the market but PHribbon integrates these calculations into the PHPP software as you work.

Buying the package with an annual subscription fee
PHribbon will be continually updated to allow for developments in PHPP, building regulations and other standards. To allow us to keep your copy of PHribbon updated we will charge an annual recurring subscription fee to fund these developments. The subscription fee will enable you to automatically receive all updates and fixes as they are released.
The first year’s subscription is included in the purchase price.
Add EPDs and gain credit
PHribbon users can engage directly with PHribbon by submitting EPDs (headline not variations) to the AECB and we will grant £5 credit for each new EPD not already present. The £5 only applies to those with an annual subscription for PHribbon, and will be granted as a reduction on your annual license subscription. You may submit and receive £5 credits up to the value of your subscription license.
EPDs will be verified by Tim Martel and once cleared by him, the AECB will send a £5 discount coupon to be used against the cost of the annual subscription fee. (Up to a maximum of the value of the subscription fee.)
Please note if you are upgrading from a previous version of PHribbon the deadline for upgrading passed in February 2023. Please purchase this new package with subscription instead.
The technical specifications
PHribbon uses Microsoft Excel as a base. No special PHPP is needed. PHribbon is compatible with PHPP v10 and designPH.
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.
Your payment confirmation email will ask for a security code which you get from a downloaded spreadsheet. Pressing the button in that spreadsheet just reads a unique code on your computer, it makes no changes whatsoever. If you change your computer in the future a new Licence Key will be sent to you free of charge.
Software will be distributed by Dropbox to enable updates to be sent to you automatically. Once you have the software, copy it from the Dropbox to your own folder. Enter the licence key at the top of the Install tab then follow the instructions below it. You will also need to enable macros, there are instructions about how to do this safely in the User Guide. (Macros are already part of PHPP v9.6 variants version written by the Passivhaus Institute.)
If you encounter an error message then please report it so it can be resolved.
The Build PHPP buttons
Examples of CO2 data
- built-in library of 291 entries from EPDs containing the Full Life info for stages A-D and a further 140 from ICE 2019 with manufacturing data (A1-A3)
- includes CO2 stored in timber and timber based materials, also called sequestered CO2. This is calculated where it has been omitted in the EPD.
- standard RICS methodology including 60 year nominal life
- filters EPDs, choose whether you want to see products manufactured within your country, a region e.g. Europe, or all the EPDs
- matches materials automatically, you only need adjust the choice where necessary, you can now also see both the original material and the material it was matched with, in case there is a difference
- remembers associations you make between phrases in the PHPP and materials
- coloured results, the output table is coloured by value to make it easy to see where the CO2 is coming from
- fully transparent calculation
- up to 4 options can be graphed/compared
- simpler format and option to simplify further so only the names of the materials and results are shown
- density, you can change the density of products where units are “kg” in the final output sheet (you can also change any in PHribbon’s library)
- Scope Summary written below the calculation for you to keep a record of exactly what is included
- RIBA results gives RIBA 2030 Challenge results and gives data in the format for RIBA awards applications
- Total CO2 graph shows operational and embodied CO2 over 60 years (Button also to extend this >60 years)
- AECB Assessment summary that is printable
- LETI results graphic and detailed tables, all laid out on printable pages
Results are also given by each stage for each material. The automatic colouring makes it easy to spot what material is contributing most and at what stage:
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.
