"A recent building code change for new construction could reduce emissions by requiring use of solar panels and batteries, raising prices in an already expensive state."
"California has led the nation in fighting climate change by encouraging the use of renewable energy and electric cars. Now the state is taking on an even harder challenge — reducing emissions from homes, businesses and other buildings that have to be heated, cooled and powered.
This month, state regulators updated California’s building code to require new homes and commercial buildings to have solar panels and batteries and the wiring needed to switch from heaters that burn natural gas to heat pumps that run on electricity. Energy experts say it is one of the most sweeping single environmental updates to building codes ever attempted by a government agency.
But some energy and building experts warn that California may be taking on too much, too quickly and focusing on the wrong target — new buildings, rather than the much larger universe of existing structures. Their biggest fear is that these new requirements will drive up the state’s already high construction costs, putting new homes out of reach of middle- and lower-income families that cannot as easily afford the higher upfront costs of cleaner energy and heating equipment, which typically pays for itself over years through savings on monthly utility bills."
