Building Transparency is proud to partner with The Passive House Network (PHN) and the Association for Environment Conscious Building (AECB) for the US launch of the PHN PHribbon, a toolbar add-on for Excel. Developed in association with the PHN, AECB and Building Transparency, this add-on enables Passive House designers to calculate the embodied carbon of a given design within the Passive House Planning Package (PHPP), an easy-to-use planning tool for energy efficiency. Integrated with the Embodied Carbon in Construction Calculator (EC3), PHribbon gives users unparalleled power to forecast the carbon emissions impact of their designs.
Tim Martel, Certified Passive House Designer, Chartered Architectural Technologist AECB expert and course tutor on the AECB CarbonLite ™ Retrofit Course wrote PHribbon. It is an Excel add-on that makes using PHPP quicker and easier and draws on existing national and global database information for materials and products’ environmental impact. It estimates cradle-to-grave carbon emissions, helps users build PHPP models, and includes several useful tools and features.
The PHPP energy balance design tool contains everything necessary for designing a properly functioning Passive House, a building standard that is energy efficient, comfortable, affordable and ecological. The program prepares an energy balance and calculates the annual energy demand of the building based on the user input relating to the building’s characteristics.
Ken Levenson, Executive Director of PHN said: “As more leaders across the building industry are prioritizing a positive climate impact for their structures, by utilizing the PHribbon, designers can tackle both operational and embodied building carbon emissions within the PHPP tool, and comprehensively push for carbon neutral and negative buildings across the US.”
PHribbon leverages existing information beyond just energy, pulling from Building Transparency’s EC3 database, and EPA carbon figures for electricity, the end-of-life of materials, and the end-of-life pathway.
Stacy Smedley, Chair and Executive Director of Building Transparency said: “Building Transparency’s mission is to provide the open access data and tools necessary to enable broad and swift action across the building industry in addressing embodied carbon’s role in climate change. Partnering with PHN to support programs like the PHribbon furthers that mission. We are proud to work with PHN to integrate EC3’s 50,000 materials records into the tool to help clarify whole life carbon emissions for a building’s design and influence positive procurement decisions.”
Andrew Simmonds, CEO of AECB said: “Collaboration with PHN and Building Transparency marks a step-change in the AECB’s strategic goal to build more and stronger international partnerships. We enthusiastically welcome the positivity and synergy that is already flowing from this joint initiative.”

The Passive House Network (PHN) formerly known as NAPHN, is a 501(c)3 that provides Passive House high-performance building education and resources to professionals across the U.S. that transform how they think and work with buildings. PHN provides professionals a complete skill set to reliably produce new and renovated buildings that use dramatically less energy for effective and affordable climate action.
Building Transparency is a 501(c)3 non-profit organization that provides open access data and tools that support broad and swift action across the building industry in addressing embodied carbon’s role in climate change. Formed in 2020, Building Transparency hosts, manages and maintains the Embodied Carbon in Construction Calculator (EC3) tool, which provides thousands of digitized EPDs in a free, open-source database, and Tally, the non-profit’s Life Cycle Assessment Tool. Building Transparency strives to provide the resources and education necessary to promote adoption of the EC3 tool, including through the official materialsCAN program, and works with global policymakers to shape a better building future.
Availability of UK version of PHribbon
The current UK version of PHribbon Version 4.04 is available through the AECB https://aecb.net/aecb-phribbon
Tim Martel said: “The UK version gives PHPP and non-PHPP users a simple and quick way to check their designs against LETI and the recently updated RIBA targets. US and Canadian versions give PH Designers quicker and easier access to their EC3 database within PHPP. In each case the advantage of using the version in PHPP (PHribbon) is that it also calculates the Operational CO2 and combines that with the Embodied on to a single graph.”
