Washington state moves to electrify new buildings by requiring heat pumps

Dozens of all-electric buildings are sprouting across Washington state as more developers ditch gas-fired systems in a bid to curb pollution. A diverse array of facilities now use electric heat pumps to warm rooms and water supplies, including a renovated K-8 school in West Seattle, a community center for the Skokomish Indian Tribe, a youth theater in Bellevue, and Microsoft’s corporate campus kitchen in Redmond.
