Washington's biggest buildings meet their first energy deadline

How the standard measures your building

The standard runs on one number: energy use intensity, or EUI (a building's annual energy use divided by its floor area, a measure of how much energy it burns per square foot). The state Department of Commerce sets a target EUI for each building type, and owners report their actual number through ENERGY STAR Portfolio Manager, the free federal tool for benchmarking a building's energy against that target. If your building beats its target, you document it. If it misses, you have to show a plan to close the gap.

This is not the energy code that governs new construction. The code tells a builder how to build; this standard tells an existing building how it has to perform once the doors are open, measured and reported on a schedule. The first group, buildings larger than about 220,000 square feet, faces a compliance deadline in 2026. Smaller commercial buildings, down to roughly 50,000 square feet, follow in later years, which is why owners below the first cutoff are watching this round closely.

Retrofit, exempt, or pay

For an owner, the honest math comes down to three paths. Meet the target, often through lighting, controls, heating and cooling upgrades, or better operations. Qualify for a compliance path by filing an energy management plan and an operations and maintenance program, which can buy time. Or miss the deadline and face a penalty, which the statute sets on the order of a few thousand dollars plus roughly one dollar per square foot for each year out of compliance, per the state's rules.

Help exists, but it is thinner than it was. Commerce ran an early incentive program that paid owners on the order of a dollar per square foot to benchmark and comply ahead of schedule, and those funds have been limited and largely committed. Your utility is the more durable source: Puget Sound Energy, Seattle City Light, Avista, and others run commercial efficiency rebates that can offset a chunk of a retrofit, though amounts and eligibility shift year to year.

How many are actually on track

Nobody outside Commerce has a clean, public count of how many of the largest buildings will hit their target on time, and the agency's own picture firms up as reports come in. What the crew can say plainly is that benchmarking and planning take months, so a building that has not started by late 2025 is working against the clock. The compliance portal is the place to confirm whether a specific building is even on the list and what target applies to it.

Washington adds a regional wrinkle. Much of the state's electricity comes from Columbia River hydropower marketed by the Bonneville Power Administration, so a building's carbon footprint here is lower than the same building in a coal-heavy state. This standard is still about energy use, not just carbon, and it sits alongside the Clean Energy Transformation Act, the 2019 law requiring the state's electric utilities to reach 100 percent clean electricity by 2045. Using less, not just cleaner, is the point.

Worth watching this month

1. The 2026 compliance deadline for buildings over about 220,000 square feet, the date on which penalties can begin to accrue, is the one hard milestone to confirm against Commerce.

2. The Commerce compliance portal, where an owner can check whether a building is listed and what target EUI applies, is worth a look now rather than in the spring.

3. Whether the Legislature's 2026 session adjusts the standard's timelines or penalty structure is routine to track but could matter if it moves.

4. The status of any remaining Commerce incentive funds, which have been limited and may already be fully committed, is worth confirming before counting on them.

5. Your utility's current commercial efficiency rebates, which can offset retrofit costs and change from year to year, are the most actionable thing on this list.
