The NAPHN version of PHribbon is for the USA and using the US Customary units version of PHPP. The key feature is the Embodied CO2 module which brings into PHPP entries from the Building Transparency EC3 database, and EPA CO2 figures for electricity, the end of life of materials and the end of life pathway.

  • EC3’s API used to retrieve the data, this will be updated once a year
  • 44,000 records from the EC3 database stored in PHribbon and transferred to your PHPP as individual entries as needed
  • metric data converted to e.g. CO2 per cubic foot for concrete, per square foot for glass, per ft for  I-joists

The US version also has the other tools that help you build your PHPP: the window and D-reveal tools, check tool and R value libraries. In the “Windows” tool instead of entering figures in mm or meters you can enter any of these formats:
5′     5’4″   5’4    64″    64.75″
5’4 3/4″

Shown  on the right are the Embodied CO2 button, main Embodied CO2 menu and (below) an example dialogue entry form.

You select materials from your R-value calculation, PHribbon matches those up with entries from it’s library for you to choose from.

The Beta version is ready now. We are asking NAPHN to identify 5 users to receive a free working copy it in return for feedback.
Those 5 users will also get the final version at a reduced price.

The Final version will be available from July-Aug from
