Proposed Session Description
The Alliance's working group on embodied carbon is putting together a proposal for RESNET to create a new standard which would add embodied carbon to the HERS index. HERS Raters currently capture data points needed to calculate Operational Emissions for the HERS Index; 65 of these data points overlap with those needed to calculate Embodied Carbon Emissions. With software innovations made to RESNET Accredited HERS Rater Software Systems, designers and builders could dial in on both operational and embodied carbon-in-materials targets, making strategic choices to lock in up-front carbon savings. NEHERS is seeking funding to have the RESNET Accredited HERS Rater Software Systems and embodied carbon calculation tools integrated, as well as, to do a baseline study, which could be used to determine a carbon baseline reference home standard. If included in the HERS Index, it would become part of what is already the gold standard for home energy assessments in the residential home market, transforming the HERS Index into an even more powerful tool for tackling climate change within the next 10 years.
Diversity and Inclusiveness
The presentation will be placed in the widest lens possible, looking at global issues of climate change as it relates to relations between wealthy and poor nations, and the need for wealthy nations to stop making a mess for everyone else and to do our part to clean up the mess we have already made. Our speaker panel is diverse in terms of gender and age.
Learning Objectives
This is a critical environmental and social justice issue that goes beyond adding solar panels and eating less meat. Global majority and indiginous people around the world are calling on the wealthy nations to address our relationship to poor nations, which have for centuries been based on the extraction of resources for the profit of a few, but to the detriment of all. Indiginous populations make up only 5% of the world's population but have preserved over 80% of the world's biodiversity. In contrast, the US also makes up about 5% of the worlds population, but emits roughly 25% of the global carbon emissions. Wealthy nations must do everything in our power to curb our disproportionate amount of emissions, so that those with the ancient knowledge can lead us toward regaining balance. Sequestering carbon must be an essential part of the stragegy. Calculating embodied carbon emissions is a key step towards being able to quanitfy and then reduce, and ultimately, sequester carbon in the built environment. The time is short. We must act now.
Scaling and accessibility of the Life Cycle Assessments and Environmental Product Declarations - There is industry wide agreement that the tools are ready for primetime - Embodied Carbon Construction Calculator (EC3) enrolled over 10,000 users across the construction sector in 12 months – that was as of December 2020 - Real time digital outputs of EPD, for example in Concrete installations – installers are able to deliver the EPD upon delivery based on real materials
Software- Hurdles and Opportunities - Funding… We have adopted a “build it and they will come” philosophy. By securing widespread support for the initiative, the funding group or groups will naturally emerge - Federal funds - Programs: Buildings America as example - Timeline: 2-5 Years - Establishing an Embodied Carbon Baseline Building within the HERS Standards will be used to compare installed vs baseline for embodied carbon, similar to how the current HERS index uses a reference home as a baseline to calculate operational savings. -Embodied Carbon Baselines already exist – See State of Washington Concrete baseline study - Consistency – the RESNET Standards are well equipped to assure consistency in the Embodied Carbon marketplace - Maintenance: - the Life Cycle Assessment (LCA) and Environmental Product Declaration (EPD) process is mature and growing exponentially over the past 24 months - Potential Software collaborations are available – Ekotrope is positioned to lead integration - Embodied Carbon Cosntruction Calculator (EC3) is open source and is an example of widely adopted LCA/EPD software
Workforce Development: - We anticipate substantial HERS Rating growth over the next decade - Presently approximately 2000 HERS Raters in the US – 550 in Texas alone, NEHERS has 226 rater members - The existing rater development pipeline can scale, and has simultaneously shown versatility across new market opportunities - HERS H20 as example - Federal, State and municipal Program Adoption is critical to rollout. - A new standard from RESNET on Embodied Carbon would encourage federal, state and local municipal program adoption.

Additional Comments
We hope to present this at the RESNET conference a week before NESEA but haven't heard back yet if our proposal was selected.
Session Format
Presentation followed by facilitated discussion or breakout groups
Anything else you'd like to tell us about your session proposal?
Getting RESNET to take this proposal seriously will require a broad base of support from the industry, which we hope this presentation will help generate.

Full Description
As of 2017, operational emissions (28%) and embodied material emissions (21%) accounted for almost half of global carbon emissions. The up-front carbon savings that come with factoring embodied carbon emissions into our design calculations will be essential to meet the 10-year timeline on reversing climate change. We cannot wait for the perfect time or the perfect tools. We must do this now, even as the Environmental Product Disclosure (EPD) databases and Embodied Carbon (EC) tools are evolving. Enough work has been done for those tools to be integrated into current RESNET accredited software. If RESNET is going to adopt this proposal, we need to show a wide base of support for the initiative; we want to use this session as a launch pad for widespread industry support.
