Berkeley triggered a chain of anti–natural gas laws

Earlier this year, Berkeley became the first city in the country to ban natural gas in newly constructed buildings

Generations from now, people might react to the idea of piping gas into houses the same way we now think of burning coal in the fireplace for heat: as a relic of a less-advanced and soot-filled time.

The turning point came earlier this year, when Berkeley, California, became the first city in the country to ban natural-gas in newly constructed buildings in July. Within a few weeks, four other cities in California passed their own rules to encourage buildings to use only electricity, which means no gas for heating or cooking. Two more cities, Menlo Park and Santa Monica, followed suit last week. At least 50 California cities — including the biggies: Los Angeles, San Jose, San Francisco, and Sacramento — are considering similar plans. And the trend has crept out of California, with Seattle and Brookline, Massachusetts mulling their own proposals.

“This is a very exciting year: It’s kind of a tipping point,” said Stet Sanborn a principle at SmithGroup, an architecture and engineering firm. Local governments were primed to follow Berkeley’s lead because they’ve made carbon-cutting pledges.

“They all have signed pacts and passed resolutions,” Sanborn said, “and now that movement is starting to happen, no one wants to be left behind.”

For developers, too, gas just doesn’t make sense for California buildings anymore, Sanborn said. It’s now less expensive and more convenient to do without it. “All of the all-electric buildings I’ve done have been at cost or lower [than those with gas] because you’re not paying for gas lines to be connected and run all through the building,” he said.

No surprise that the gas industry sees things differently, warning that forcing everyone to go electric could increase costs and, perversely, worsen pollution. “Pursuing clean energy should include looking for ways to reduce energy consumption, utilizing the current energy infrastructure in the most efficient way,” wrote the American Public Gas Association.

Cities have been turning to Sanborn and other engineers for advice in crafting the new rules so that they don’t pass something that backfires. It’s not better, from a carbon-cutting perspective, to trade gas for electricity if that electricity comes from a coal plant, Sanborn said. That’s because heating a home with gas is cleaner than burning gas and coal to produce electricity, then converting that electricity back into heat once it reaches your house.

California gets a little more than half of its electricity from low-carbon sources — wind turbines, solar panels, dams, and one nuclear power plant — which makes electric heating a smarter choice, even before considering new evidence that aging networks of city pipes are leaking much more greenhouse gas than previously suspected, Sanborn said.

The Berkeley ban outlaws gas in new single family homes starting in January. It will apply to the construction of larger buildings as soon as state regulators put the finishing touches on standards for all-electric buildings. Most of the other cities that have passed ordinances are taking a more moderate approach. Builders in those cities will be able to connect to gas pipelines only if they compensate by making their buildings more energy efficient — by improving insulation, for instance, and using more efficient lighting. That increases costs and provides a nudge to get builders and architects used to doing things the old way a reason to look at the electric alternative.
