Washington is the first state to require all-electric heating in new buildings – Crosscut

Dozens of towns and cities in California, Washington, Colorado and Oregon have already effectively banned gas in most new buildings.New York City did the same in December. At the state level, California also adopted a landmarkbuilding code changelast August that strongly encourages new buildings to forgo gas hookups, but does not mandate it.

At the same time, the gas industry is vigorously fighting these policies and asserting that it will be possible to cut emissions from buildings using lower-carbon fuels like gas from landfills andclean hydrogen.At least 19 Republican-led state legislatureshave passed preemption laws that prevent municipalities from banning gas.

In Washington, the revised code came in response to a target set by the state Legislature to reduce the amount of energy consumed by nonresidential buildings by 70% by 2031. A2021 Washington state energy strategy reportalso found that electrification and energy efficiency were the most cost effective ways to achieve state greenhouse gas targets for buildings.

While Washington is the first state with an all-electric mandate, the California Energy Commission, which oversees the state building code, passed a similar policy last August that will also go into effect in 2023. The California code sets a baseline efficiency standard that all but requires the use of heat pumps for space heating. Developers have the option to install other types of heating as long as they adopt a raft of energy efficiency measures. The California code is also more flexible in regards to water heating.

Washingtons new code does contain a few exceptions for hospitals, research facilities and other buildings where fossil fuels are required for specific needs that cannot practicably be served by heat pump. Large commercial buildings in Eastern Washington, where the temperature can get down into the negative teens, are also allowed to use gas heating as a backup option. The code requires only that 50 percent of a buildings water heating needs are fulfilled using heat pumps.

No state is yet considering a ban on the use of gas for cooking though some of the local gas bans do apply to stoves. Kocher said the space and water-heating mandate is likely to prevent most commercial developers from hooking up new buildings to the gas system altogether. He also didnt want to invite further opposition to the idea by angering the restaurant industry, which has proved to be afierce opponent to gas bans in places like Berkeley, California.

We do need to stop putting gas lines in for all end uses. But we thought that this was a pretty big code change as it is, he said.
