The NAPHN PHribbon is an embodied carbon calculator and empowers Passive House designers to calculate the embodied carbon of a given design within the PHPP energy balance calculating tool – giving users unparalleled power to forecast the carbon emissions impact of the design.

In addition, the NAPHN PHribbon makes using PHPP quicker, easier and it uses the existing information beyond just energy. It’s written by Tim Martel, a Certified Passive House Designer, Chartered Architectural Technologist and expert and produced by the AECB.

If you want your building designs to maximize positive climate impact, don’t just build a Passive House, but utilize the NAPHN PHribbon and let’s push for carbon negative buildings!
