Santa Monica City Council Votes To Approve Zero-Net Energy Building Requirement

The Santa Monica City Council voted to approve an ordinance requiring all new single-family construction in the City of Santa Monica to be zero-net energy (ZNE). Zero-net energy is a building industry term for projects that generate enough of their own energy from renewable sources to equal what they take from the power utility over the course of a year. 
“This ordinance makes environmental and economic sense,” says Dean Kubani, Santa Monica’s chief sustainability officer. “With the price of utility power continuing to rise, ZNE homeowners will avoid escalating costs while benefitting from local renewable power for all of their energy needs.”

The ordinance now goes to the California Energy Commission (CEC) for approval, and continues the City’s history of adopting local requirements, and providing resources to the community, that take a lead in advancing the transition to high performance, green buildings for all.
“Santa Monica’s zero-net energy ordinance is a measure that will help California meet its statewide energy efficiency goals,” says Assembly member Richard Bloom. “This ordinance reflects the city’s leadership on local policymaking as well as its commitment to doing its part to reduce greenhouse gas emissions and energy consumption.”
There are various definitions for ZNE buildings but Santa Monica is adopting the definition used in the 2016 California Green Building Standards Code (CALGreen). According to CALGreen, a ZNE building is one where the value of energy produced on-site by renewable energy resources is equal to the value of the energy consumed annually by the building.
In 2008, the California Public Utilities Commission (CPUC) adopted California’s Long Term Energy Efficiency Strategic Plan, which presented a roadmap for all California buildings to be ZNE. The roadmap committed California to requiring all new residential construction achieve ZNE by 2020 and all new commercial construction achieve ZNE by 2030.
With this new ZNE ordinance, Santa Monica is the first city in California to adopt a ZNE ordinance, leading the State to ensure new construction meets the most energy-efficient, cost-effective standards in the industry.

“Santa Monica is proud to take a global lead in zero net energy building standards that put the State’s environmental policy to action. Council’s adoption of this new ordinance reflects our city’s continued commitment to the environment,” says Mayor Tony Vazquez. “ZNE construction, considered the gold standard for green buildings, is a major component that will help us reach our goal of carbon neutrality by 2050.”

Santa Monica staff collaborated with Southern California Edison (SCE) and their consultant, TRC Energy Services (TRC) to analyze the cost-effectiveness of locally adopted standards that meet the CALGreen ZNE requirements.
The timing of the ordinance capitalizes on state momentum towards ZNE and market trends in the solar industry. With the cost of solar installation continuing to decrease (according to the California Solar Initiative, the Solar Energy Industries Association and observed recent installations in Santa Monica), Santa Monica residents and developers can combine cost-effective energy efficient design with affordable renewable energy to build ZNE homes. These new homes will contribute to the City’s robust long-range goals for energy and climate mitigation, including releasing zero carbon by 2050.
In addition to ZNE for single family homes, the Santa Monica ordinance also requires non-residential construction be designed to use 10 percent less energy than required by the 2016 California Energy Code.
The Update to the Santa Monica Municipal Green Building Ordinance states:
SINGLE FAMILY/DUPLEXES/LOW-RISE MULTI-FAMILY DWELLINGS shall be designed to use 15 percent less energy than the allowed energy budget established by the 2016 California Energy Code, and achieve and Energy Design Rating of Zero.
HIGH-RISE MULTI-FAMILY DWELLINGS and NON-RESIDENTIAL, HOTEL, MOTEL shall be designed to use 10 percent less energy than the allowed energy budget established by the 2016 California Energy Code.

  1. Sounds like Santa Monica has given up on affordable housing or is trying to insure that only the wealthy will build their homes there. Why not share the sustainability burden with all the current residents rather than just wealthy newcomers? Make energy upgrades mandatory city-wide over say the next 10 years. Make roof insulation inspections a requirement on all re-sales. Make sale and installation of lower efficiency appliances, water heaters, heating and a/c equipment all illegal. Issue fines for all outdoor lighting that’s not LED equipped and inspect all indoor lighting before each closing to insure LED use. Make the sale and licensing of autos over 20 years old illegal within the city limits. Spread the pain.
