California Green Building Standards Code Compliance Forms – This 2022 Calgreen Code Change Summary will provide a detailed review of the new code changes. The changes will take effect across California on January 1, 2023.

The California Green Building Standards Code contains standards applicable to residential and non-residential buildings throughout California, including schools and community colleges.

California Green Building Standards Code Compliance Forms

The California Green Building Standards Code, also known as “CALGreen”, undergoes an update and approval process by the California Energy Commission (CEC) every three years. Once the CEC approves the changes they are submitted to the California Building Standards Commission for ratification into state law.

Additionally, the California Department of Housing and Community Development (HCD) also reviews and adopts codes for all residential buildings. HCD may not adopt certain changes to the CalGreen Code. This can cause some confusion when it comes to your CalGreen permit application. Review the Matrix Adoption Table at the beginning of each chapter of the CalGreen Code to determine if a specific code section applies to your project. Here is the Chapter 1 Matrix Adoption Table from the 2022 Code. You can see HCD adoption in Column 4.

To add further confusion, your local jurisdiction may have added further variations to the requirements for your area. For this reason you should always check with your local building department.

The following is a list of all the significant changes from the 2019 Green Building Standards Code to the 2022 CalGreen Building Standards Code. We have omitted some irrelevant changes that have no impact on the requirements.

Two new definitions were added regarding electric vehicle locations and a Level 2 EVSE device was defined.

What Are Title 24 Requirements For Lighting?

Electric vehicle (EV) enabled locations. A vehicle space with electrical panel space and load capacity to support a branch circuit to support EV charging and the necessary raceways mounted underground and/or surface.

Electric vehicle (EV) ready space. [HCD] A vehicle space that is provided with a branch circuit; Any required raceways, both underground and/or installed on the surface; To accommodate EV charging, terminating in a receptacle or charger.

Level 2 Electric Vehicle Supply Equipment (EVSE). [HCD] 208/240-volt 40-ampere branch circuits, and electric vehicle charging connectors, attachment plugs, and all other fittings, devices, power outlets or equipment installed specifically for the purpose of transferring energy between premises wiring and electric went. Vehicle.

High-efficiency vehicles regulated by the US EPA, which have a fuel economy and greenhouse gas rating of 9 or 10, as regulated under 40 CFR Section 600 Subpart D.

301.1 Existing Parking Facilities: The mandatory provisions of Section 4.106.4.2 may apply to additions or alterations to existing parking facilities or the addition of new parking facilities serving existing multifamily buildings. See Section 4.106.4.3 for application.

4.106.4 Electric Vehicle Charging for New Construction: (The entire section has been significantly changed. The code now has specific requirements for new multi-family dwellings with less than 20 dwelling units and for those with more than 20 dwelling units. Provides. This includes requirements for future EVSE Level 2 chargers and more. We will write a separate article on the new EV charging station requirements as the changes are too numerous to list here. Note that the requirements still include requirements for future chargers. Provisions are required, and there is no time to set them up here.)

5.106.5.3 (The entire section has been significantly changed. The previous separate requirements for single location requirements and multiple location requirements have been eliminated. The code now has specific requirements for warehouses, grocery stores, and retail stores. Provides. Future EVSE Level 2 chargers are required and much more. We will write a separate article on the new EV charge station requirements as the changes are too numerous to list here.

Exception: Surface parking areas covered by solar photovoltaic shade structures or shade structures with roofing material that comply with Table A5.106.11.2.2 in Appendix A5, permitted in whole or in part in lieu of shade tree planting. Will go.

Environmental Product Declarations

1. Walkways, hardscape areas covered by solar photovoltaic shade structures or shade structures with roofing material that comply with Table A5.106.11.2.2 in Appendix A5 may be covered in whole or in part in exchange for shade tree planting. Permission will be given from.

2. Designated and marked sports areas of organized sports activity are not included in the calculation of the total area.

A new section has been added with detailed requirements on CO2 monitoring and control (DSA-SS) in classrooms. As this section applies only to schools regulated by the DSA, we have not copied the detailed list of items noted in paragraphs 1 to 6. The following is the first paragraph of the new requirements.

5.506.3 Monitoring of carbon dioxide (CO2) in classrooms. (DSA-SS) Each public K-12 school classroom, as listed in Table 120.1-A of the California Energy Code, shall be equipped with a carbon dioxide monitor or sensor that meets the following requirements: (Additional requirements for Code See. )

Interesting Fact: If your local jurisdiction has adopted Tier 1 or Tier 2 requirements, these are not voluntary for your project. it’s mandatory!

There has been a significant change in EV ready requirements for new multi-family development projects and hotels and motels. If you’re in a Tier 1 area (like Santa Rosa), they now require 35% of total parking spaces to be EV ready. This means that the power distribution system must be designed to handle this full load. Tier 2 locations will require 40% of parking spaces to be EV ready (like Palo Alto).

A4.106.8.2 New multifamily development projects and hotels and motels. New multifamily development projects and hotels and motels shall meet the following requirements.

Tier 1. EV ready. Thirty-five (35) percent of the total number of parking spaces will be equipped with low power level 2 EV charging receptacles. For multifamily parking facilities, when more than one parking space is provided for use by a single dwelling unit, no more than one receptacle is required per dwelling unit.

The Energy Design Rating (EDR1) compliance margins have been significantly revised and no longer have different requirements for mixed fuel versus all-electric. See Table A4.203.1.1 for details.

A4.203.1.2 Prerequisite Options. In addition, it will be necessary to meet at least two of the efficiency measures specified in section A4.2.

Added minor references to the California Energy Code. The CalGreen checklist has been updated to reflect the revised EV charging requirements.

Tier 1 and Tier 2 clean air vehicle parking requirements. The Tier 1 requirement has increased from 10% to 35%. The Tier 2 requirement has increased from 12% to 50%. (Does anyone else think this is just crazy?)

Building & Safety

A5.106.5.3 Electric Vehicle Charging (This entire section has changed and new terminology has been added. We will write a separate article on the new EV charging station requirements as the changes are too numerous to list here.)

The only change is the revised CalGreen checklist that indicates changes to EV charging stations for both Tier 1 and Tier 2 requirements.

No changes were made in this section. This is not surprising since OSHPD does not follow CalGreen voluntary measures. Instead, they are required to follow the PG&E Savings by Design program. Which raises the question – why does this section exist at all?

As far as code changes go, these don’t move the needle much. Changes in electric vehicle charging station requirements are likely to cause some headaches for electrical engineers. If some commercial buildings catch the 50% EV charging space requirements (Tier 2) they could see a significant increase in the size of their electric service.

The changes in this code cycle highlight a fundamental problem with the CalGreen code. The problem is that it is under the control of the California Energy Commission (CEC). The CEC’s primary concern is energy efficiency, and we can see it in these code changes. What we don’t see is a single improvement in sustainable design! In three years of investigating improvements to California’s sustainable design, they came up with nothing.

This code cycle highlights a real problem with California’s sustainable future. The problem is that energy efficiency goals often differ from sustainability goals. A wise old engineer I once worked with was discussing his new library with a famous city. The issue of energy efficiency and LEED compliance came up.

“Well,” says the wise old gray hair, “I can give you an energy efficient building, or I can give you a LEED building, but I can’t do both.”

There is some truth in that statement. Although I hate the idea of ​​more government, I believe that California’s sustainable code should be taken out of the control of the California Energy Commission and placed under the control of a department dedicated to sustainable design. Leaving California’s sustainable design future under the control of the CEC will result in virtually no progress in sustainability.

Online Permit Center: Getting Started

Sustainable design is more important than ever in California. The fact that the CEC failed to move the needle at all is a clear indication that this job should be taken out of their hands. It should be under the control of an organization that understands and promotes sustainable design.
