What is in the new national definition of a Zero Emissions Building and why does it matter? The U.S. Department of Energy (DOE) and US Environmental Protection Agency (EPA) worked with industry stakeholder to define a zero emissions building as: "A building that is highly energy efficient, does not emit greenhouse gases directly from energy use, and is powered solely by clean energy." Let's break it down: 'highly energy efficient' = An existing building with an ENERGY STAR score of 75 or higher and a new construction building with an ENERGY STAR score of 90 or higher. 'does not emit greenhouse gases' = An all-electric building. 'powered solely by clean energy' = 100% renewable energy supplied from a combination of on-site and off-site sources. Why this matters: The current industry definitions of zero emissions buildings, or net-zero energy buildings, or zero energy buildings were...well...you get the point. They were similar, but not the same. The building industry now has one name and definition to point to. For me this is government work at its best - help the industry align and we can all move forward faster! Also...get ready for more. Where government definitions lead, regulations are likely to follow. This definition paves the way for grants, tax credits, standards, and other policy mechanisms that can be tied to this high bar of building performance. Finally...stay tuned for part two. This definition only covers operational emissions from buildings. Conversations are already underway on how to define the emissions from the manufacturing and construction of buildings, i.e. embodied carbon. https://lnkd.in/eHFjebmT.

The "directly from energy use" restriction on emissions seems to be a huge miss- at Thalo Labs, a zero emissions building means zero emissions from combustion AND leakage. Refrigerant leakage is a huge issue that will grow as we electrify, but not yet currently getting the air time it deserves. U.S. Department of Energy (DOE) US Environmental Protection Agency (EPA)
