The California Energy Commission updates the standards every three years.

2019 Building Energy Efficiency Standards

Buildings permitted on or after January 1, 2020, must comply with the 2019 Standards.

The 2019 Building Energy Efficiency Standards improve upon the 2016 Energy Standards for new construction of, and additions and alterations to, residential and nonresidential buildings. This is commonly referred to as the 2020 building codes.

Standards ensure that builders use the most energy efficient and energy conserving technologies and construction practices, while being cost effective for homeowners over the 30-year lifespan of a building.

  • The standards require solar photovoltaic systems for new homes.
  • Improve the building’s thermal envelope through high performance attics, walls and windows to improve comfort and energy savings.
  • Attic insulation to be a minimum of R-38 to meet high energy efficiency 2020 standards.
  • Windows to be double pane with argon gas and Lowe-E minimum for all housing.
  • Standards update indoor and outdoor lighting making maximum use of LED technology.
  • The standards enable the use of highly efficient air filters to trap hazardous particulates from both outdoor air and cooking and improve kitchen ventilation systems.

PACE Program HVAC upgrades can include Filtration to meet 2020 codes:

  • 100 times more effective than a standard one-inch throwaway filter or ionic-type room appliance
  • Delivers cleaner air and more of it
  • Reusable filter can be cleaned by vacuuming

2022 Building Energy Efficiency Standards

Proposed standards will be adopted in 2021 with an effective date of January 1, 2023

The 2022 Building Energy Efficiency Standards will improve upon the 2019 Energy Standards for new construction of, and additions and alterations to, residential and nonresidential buildings.

Interested parties should be aware the California investor-owned utilities (IOUs) and some publicly owned utilities (POUs) conduct the statewide Codes and Standards Enhancement programs through ratepayer funds. Investor-owned utilities (IOUs) are private electricity and natural gas providers. California Public Utilities Commission (CPUC) oversees IOUs. Pacific Gas and Electric, San Diego Gas and Electric, and Southern California Edison comprise approximately three quarters of electricity supply in California. Modernization of the power grid to convert homes to go solar will be adopted by IOUs. Rates for non-solar participants will increase to pay for these transitions to meet California’s lower emission standards.Southern California Edison owns and operates the largest portion of power grids in Southern California and is working to modernize the grid.

Explanation of how NET Metering works:

“Some utility providers will convert your credits to cash back at the end of the year. Check with your local utility provider.”

Although outside the scope of the Energy Commission’s rulemaking proceeding for the 2022 Energy Code, these initiatives are important. The Energy Commission expects the IOUs and POUs to engage building industry stakeholders in developing those initiatives so they will be vetted with affected stakeholders before the utilities propose potential revisions to the Energy Code.

California Solar Initiative

The leading cause for air pollution and carbon emissions is electricity production. An overwhelming majority of our electricity comes from burning fossil fuels to create electricity. With hydroelectricity plants being closed down more often in California due to the negative impact it has on their surrounding ecosystems; alternative means of electricity production are being sought after. Solar is the most affordable and reliable source of renewable energy

The cost of a PV system depends on the system size, equipment options (panels and inverters), permitting costs, and labor costs. Prices vary depending on other factors as well, such as whether your home is new, where the system is installed on your premise, the PV manufacturer, and other factors.

The total average cost of an installed residential PV system under the California Solar Initiative is $8.70 per Watt (including installation, as of January 2011). That translates to about $34,800 for a four-kilowatt system, the average size of a residential installation.

ITC Solar investment tax credit

A federal investment tax credit for both residential and commercial consumers is available for both photovoltaics and solar water heating systems. the solar ITC for residential system owners is 30% of the total system cost with no upper limit. The 30% rate is available for systems placed in service through December 31, 2019. The credit drops to 26% through the end of 2020, then 22% through 2021 before dropping to zero by the end of 2021.
The federal tax credit is a one-time credit, but may be carried forward (and possibly back) if not completely useable in the system installation tax year. Rules about carrying forward and backward may vary between residential and commercial tax filers; please consult a tax professional for the current rules.

Explanation of how the Solar Tax credit works:

The solar tax credit has decreased from 30% in 2019 to 26% in 2020 and is scheduled to disappear entirely in 2021. Contact our offices now to learn how to take advantage of this tremendous oppurtunity.

The solar system owner has the ability to take advantage of the solar tax credit. Entities without a federal tax liability sometimes use third-party system owner arrangements to install solar since a third-party can take advantage of the solar investment tax credit, passing along some savings to the solar system host customer.

Emergence of California legislation calling only Hybrid and Electric vehicles to be sold in California.

The California Air Resources Board (CARB) first adopted the ZEV requirement in 1990 as part of the Low-Emission Vehicle regulation. Over the last 30 years, the ZEV regulation has been modified to reflect the state of technology. Modifications adopted in 2012 along with the other two Advanced Clean Car Regulations, have set California on a path toward ZEV commercialization with the resurgence of battery technology enabling manufacturers to offer moderately priced zero emission vehicles to consumers. Electric and hybrid car sales are likely to be mandatory after 2030 based on increasing regulation.

Homeowner’s rights to get solar and
Home Owners Associations’ restrictions on solar regulations

The Solar Rights Act (CA Civil Code 714), enacted in 1978, bars restrictions by homeowners associations (HOAs) on the installation of solar-energy systems, but originally did not specifically apply to cities, counties, municipalities or other public entities. Subsequent legislation extended these restrictions to all public entities and common interest developments. These entities are allowed to impose reasonable restrictions on a solar energy system that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance. “Significantly” was not originally defined, but later legislation adopted a specific dollar amount and system efficiency impact that the legislature deemed significant. These figures were amended by AB 2188 in 2014. Currently, entities are allowed to impose reasonable restrictions on a solar energy system that do not add more than $1,000 to the cost, or limit the efficiency of the system by 10%.

Reasonable attorney’s fees incurred during a court case between a property owner and a common interest development or HOA will be awarded to the prevailing party. AB 2180 of 2008 provided even more consumer protections under the Civil Code by providing that any homeowners’ association that is not a public entity that willfully violates the Solar Rights Act must pay the solar system owner a civil penalty not to exceed $1,000. AB 2180 further provides that the approval or denial of any application submitted to authorize the installation of a system must be made in writing within 60 days. If the application is not denied within 60 days it will be deemed approved unless the delay is the result of a reasonable request for additional information.
AB 634 of 2017 extended protection to solar system installations in common areas and limits associations from establishing a general policy prohibiting the installation or use of a rooftop solar energy system for household purposes on the roof of the building in which the owner resides.
