If one category captures the spirit of LEED v5, it is Energy & Atmosphere (EA). The category has always carried the most points, but v5 fundamentally changes what they reward: the focus shifts from energy cost savings to operational carbon. A building can be cheap to run yet still high-carbon if it burns gas or sits on a dirty grid — and LEED v5 is designed to catch exactly that. This is part five of our series walking through the categories of LEED v5.
The headline: a decarbonization plan for every project
The defining change is a new prerequisite: Operational Carbon Projection & Decarbonization Plan. Every project must model its future operational carbon emissions using current energy use, grid carbon data and projected change over a roughly 25-year horizon, then set out a plan to drive those emissions down over time — through efficiency, electrification or cleaner energy. Decarbonization is no longer an optional ambition; it is the price of entry. We cover the modeling behind this in detail in LEED v5 Energy Modeling: From Cost Savings to Carbon.
The foundations underneath
Beneath that headline, the familiar prerequisites remain: a minimum energy-efficiency threshold (still grounded in ASHRAE 90.1 / Appendix G modeling), energy metering, fundamental commissioning to ensure systems actually perform as designed, and refrigerant management to limit high-global-warming-potential refrigerants.
The credits that earn the points
The credit menu rewards genuine carbon reduction rather than incremental efficiency alone:
- Reduce operational carbon — the largest single opportunity, rewarding measured cuts in emissions over the baseline.
- Electrification — eliminating on-site fossil combustion in favour of all-electric heating, hot water and cooking.
- Reduce peak thermal loads — a better envelope and smarter design that shrink heating and cooling demand at the source.
- Renewable energy — on-site or procured renewables that cut grid-supplied emissions.
- Grid interactivity — energy and thermal storage, demand response and power resilience so the building works with the grid.
- Enhanced commissioning and enhanced refrigerant management — locking in performance and cutting refrigerant emissions.
Why electrification and the grid matter now
Two ideas drive the new EA. First, electrification: as electricity grids decarbonize, an all-electric building automatically gets cleaner over time, while a gas-fired one is locked into combustion emissions for its whole life. Second, grid interactivity: buildings that can shift load, store energy and respond to demand signals help integrate renewables and stay resilient during outages. Together they reposition the building as an active participant in the energy system, not just a consumer.
What it means for project teams
Start energy modeling early — it is now the engine behind a prerequisite, not just a credit. Test electrification and envelope options in concept design, when they are cheap to change, and use the 25-year carbon projection to make the case for heat pumps, better glazing and on-site renewables. Teams that treat the decarbonization plan as a real design tool, rather than a document produced at the end, will find the EA points follow naturally.
Need the energy and carbon modeling for LEED v5?
We build the energy models and 25-year operational-carbon projections behind LEED v5's Energy & Atmosphere prerequisites and credits — and turn them into a clear decarbonization plan. Let's talk.
