California Pushes for Electric Heat Pumps
USA: The California Energy Commission is considering a new code that will shape the construction of new buildings, additions, and renovations by focusing on reducing emissions from major sources like furnaces and water heaters. This code aims to set higher efficiency standards, mandating specific components such as insulation, and promoting the adoption of electric appliances like heat pumps and heat pump water heaters. Although gas appliances won’t be banned, the shift towards electric options will simplify achieving these efficiency goals.
Heat pumps, which can both heat and cool air and water, are an alternative to traditional gas-powered furnaces and water heaters. Improving building efficiency is crucial since buildings account for about a quarter of California's emissions. Key strategies include upgrading windows, insulating homes, and replacing gas appliances with electric ones. The state's power grid, increasingly fueled by zero-emission sources, supports this transition.
The California Energy Commission updates its building standards every three years, with the latest code set to take effect on January 1, 2026. This initiative is part of California’s broader strategy to achieve carbon neutrality by 2045 and meet the target of installing 6 million heat pumps by 2030, with progress already at 25% of the goal.
