STAFF REPORT
October 11, 2022
TO: Mayor and Town Council
FROM: Sean Youra, Climate Action Coordinator
Mark Lockaby, Building Official
SUBJECT: Discuss Green Building Model Reach Code and provide direction to staff __________________________________________________________________________________ This item (formerly Item #18) was continued from the October 6, 2022 meeting.
RECOMMENDATION
Provide staff direction as to whether to include certain requirements of the green building model reach code as part of the adoption of the 2022 California Building Standards Code.
BACKGROUND
Title 24 of the California Code of Regulations contains the California Building Standards Code (also referred to herein as “Building Code”), which governs the design and construction of buildings, associated facilities, and equipment in the state. California updates these requirements every three years with the next iteration, the 2022 Building Code cycle, going into effect on January 1, 2023. All jurisdictions must adopt at least the minimum standards of the Building Code; however, State law authorizes local agencies to enact local amendments to the Building Code if reasonably necessary because of local climatic, geological, or topographical conditions (Health and Safety Code sections 18941.5 and 17958.7).
At its September 1, 2021 meeting, the Council adopted Ordinance 856 that required all newly constructed buildings to be all-electric buildings as of March 1, 2022. In doing so, Fairfax became the first jurisdiction in Marin County to require all-electric buildings for new construction. As of August 2022, 60 California jurisdictions (including Fairfax, San Anselmo, Petaluma, Contra Costa County, Santa Clara County, Oakland, San Jose, and San Francisco) have adopted ordinances requiring all-electric buildings for new construction.
The County of Marin in collaboration with local jurisdiction staff have been developing a green building model reach code since September 2021 that includes additional requirements that go beyond the 2022 Building Code, specifically for new construction and remodels of existing buildings. To develop the model reach code, County staff led a comprehensive community engagement strategy. This included engaging and garnering feedback from City, Town, and County staff; community-based organizations including environmental, affordable housing, senior/aging-in-place, and equity priority advocates; building community including developers, architects, realtors, contractors and Marin Builders Association; utilities including MCE and PG&E; and Town and City commission, subcommittee, and City Council members. Formal engagements were held with key stakeholders including (i) five monthly technical working meetings consisting of City and Town building officials and planners, (ii) one public community 2 workshop, and (iii) three focus group workshops with the wide swath of community members mentioned above. Comments on the model reach code were publicly solicited through various outreach channels (e.g., partner organization listservs, presentations, newsletters, and social media). Feedback was collected via an online survey created by County staff. A majority of respondents were in favor of all of the model reach code requirements.
In addition to the County-led outreach, Town and County staff have presented to the Climate Action Committee (CAC) on the requirements of the model reach code and solicited feedback from CAC members. Town staff has also solicited feedback from the Fairfax community regarding the key components of the model code by sharing a link to the County’s reach code survey in a recent newsletter.
The culmination of this outreach is reflected in the model reach code (Attachment 1). A summary of the key policy components of the model reach code has also been provided by County staff (Attachments 2-4).
DISCUSSION
In the following sections, the key policy components of the model reach code will be discussed along with staff recommendations for Council consideration to aid in deciding what, if any, of the model code elements to include in the 2022 Building Code adoption.
All-Electric New Construction for Residential and Nonresidential Buildings This component of the model code requires all-electric for newly constructed buildings including both residential and nonresidential buildings (Attachment 2). For comparison, minimum standards under the 2022 Building Code require all new residential projects to include either electric space heating or electric water heating. The requirements and exemptions of this component of the model code were modeled off of Fairfax’s all-electric ordinance and similar jurisdiction ordinances.
Since the Town already has adopted an all-electric ordinance for new construction, staff recommends not including this component of the model code in the 2022 Building Code adoption and instead recommends maintaining its existing all-electric ordinance.
Prior to the model reach code being drafted, CAC members had voted on recommending the Council amend the existing all-electric ordinance for new construction to include substantial remodels and other modifications, which was approved by all members at their February 15, 2022 meeting. This recommendation is also listed on the CAC’s 2022-23 Annual Action Plan.
The recommendation was based on one of the Climate Action Plan’s (CAP) measures, E-1:
Ordinances for Construction of Energy-Efficient Buildings, which includes, “Adopt requirements to phase out natural gas, beginning with new construction, then substantial remodels.” At this time, staff does not recommend amending the all-electric ordinance to include substantial remodels due to the costs it could impose on project applicants. Staff estimates that additional costs to require all-electric appliances and the necessary electrical panel upgrades that would be required to provide sufficient capacity for those appliances could range anywhere from $16,350 - $27,000. These costs would be in addition to the costs project applicants already have to pay as part of the Planning Commission approval process, as well 3 as for building permit fees, plan review, assessments, installation of fire suppression sprinkler systems, and sewer lateral replacement, all of which can range anywhere from $32,500 - $52,500. There is concern that these additional costs could cause residents considering substantial remodels to scale back their project below the substantial remodel threshold, or move forward with the project without obtaining a permit.
Flexible Compliance Pathway for Existing Single-Family Residential Building Renovations
This component of the model code amends Part 6 (i.e., the Energy Code) of the 2022 Building Code and requires existing single-family residences undergoing additions or alterations to implement additional energy efficiency and electrification measures beyond the 2022 Building Code (Attachment 3). Additional energy savings are achieved through a performance compliance pathway recently developed by the State. The Flexible Compliance Pathway is a points-based system allowing homeowners and contractors to select from a comprehensive menu of energy efficiency and electrification measures that are appropriate for the scope of their project. This requirement applies to single-family additions and alterations affecting 750 or more square feet for homes that were originally permitted for construction before December 31, 2010. The additional energy efficiency standards proposed for the single-family additions and alterations have been demonstrated to be cost-effective in modeling studies completed by the Statewide Reach Codes Program. In addition, for kitchen and/or laundry room remodels, as well as any electrical panel upgrades, this component of the model code requires electrical panel upgrades to accommodate for future electrification of all appliances. Exemptions based on hardship, infeasibility, income qualification, and other considerations are also specified in Attachment 3.
Staff recommends this component of the model code be included in the 2022 Building Code adoption with the following revisions:
• Eliminate most of the hardship exemptions and only allow hardship exemptions in the following cases:
1. The cost of achieving compliance is disproportionate to the overall cost of the project.
2. Strict compliance with the standards would create or maintain a hazardous condition(s) and present a life safety risk to the occupants. • Change the square footage threshold from 750 square feet to 200 square feet. Most of the additions and alterations in Fairfax range from 200-250 square feet, so by lowering the threshold more projects would be subject to the Flexible Compliance Pathway requirements. This would not impact the development of new ADUs or JADUs, which are exempt under the model code.
• Utilize a target factor of 50% for substantial remodels of single-family residences rather than a target factor of 40% as the model code currently includes for remodels affecting 750 or more square feet. This would raise the target scores for all building vintages in Table 2, Climate Zone 2 (applicable to Fairfax) of the model code (Attachment 1) as follows:
1. Pre-1979 Building Vintage Target Score: 15
2. 1979-1992 Building Vintage Target Score: 11
3. 1993-2011 Building Vintage Target Score: 7
4 In effect, this would incentivize substantial remodel projects to install electric appliances with higher point allocations such as HVAC heat pumps that otherwise might not be installed using the target score thresholds defined in the model reach code.
Alternatively, higher target scores for substantial remodels could encourage a greater combination of electrification and energy efficiency measures to be installed.
The Flexible Compliance Pathway allows project applicants to choose what energy efficiency and electrification measures make the most sense for the given project and which measures are most cost-effective to implement. Staff views the Flexible Compliance Pathway as a logical stepping stone towards eventual all-electric requirements for remodels and/or time-ofreplacement requirements upon burnout of gas appliances by ensuring homes are electricready and progressing the transition to install electric appliances in existing homes. As previously mentioned, the electrification and energy efficiency measures included in Table 2 of the model code have already been demonstrated to be cost-effective in modeling studies by the Statewide Reach Codes Program. Therefore, the Town would not have to conduct additional studies and submit them to the California Energy Commission (CEC), which would be the case if the Town tried to adopt alternative energy code requirements. The Flexible Compliance Pathway in the model code is also aligned with the 2021-2022 Marin County Civil Grand Jury report titled, Electrifying Marin’s Buildings: A Countywide Approach, which included the following recommendation:
“On or before January 1, 2023, Marin County and each of its cities and towns that have not already done so should adopt a reach code requiring energy efficiency measures in connection with renovations of existing residential buildings. The reach code should specify the size of the renovation that will trigger the requirement and provide flexibility by allowing the applicant to choose from a list of energy efficiency measures, including electrification of gas appliances.”
CALGreen Tier 1 Provisions for New Construction and Additions/Alterations This component of the model code amends Part 11 (i.e., CALGreen) of the 2022 Building Code. It requires all new construction, additions and alterations affecting 750 or more square feet of existing single-family and multifamily buildings, and nonresidential additions and alterations to comply with CALGreen Tier 1 provisions except for certain electric vehicle (EV) infrastructure provisions as described in the next section.
Staff recommends this component of the model code be included in the 2022 Building Code adoption with the following revisions:
• Change the square footage threshold from 750 square feet to 200 square feet for the reasons described in the prior section.
Although the CAC has not held a formal vote on recommending the Council adopt CALGreen Tier 2, the CAC’s 2022-23 Annual Action Plan includes adopting CALGreen Tier 2 under the Built Environment actions. Staff does not recommend CALGreen Tier 2 be included in the 2022 Building Code adoption and instead recommends CALGreen Tier 1 be included in the Building Code adoption as specified in the model code. Fairfax has historically adopted CALGreen Tier 1 including for the previous code cycle in 2019. Additionally, no other Marin jurisdictions have adopted Tier 2 and will likely not be adopting Tier 2 for this code cycle. The 5 CALGreen Code cautions jurisdictions that may be considering adopting CALGreen Tier 2 stating, “The measures necessary to achieve Tier 2 status are very stringent. Cities, counties, and cities and counties considering adoption of Tier 2 as mandatory should carefully consider the stringency of each measure and ensure that the measures are achievable in their location.” Therefore, to consider including CALGreen Tier 2 in the adoption of the 2022 Building Code would require staff to analyze whether each applicable Tier 2 measure is feasible to be implemented for building projects in Fairfax and identify what the potential impacts might be on residents and businesses.
Electric Vehicle Reach Code for New Construction and Renovations This component of the model code amends Part 11 (i.e., CALGreen) of the 2022 Building Code. It requires that all new construction comply with CALGreen Tier 1 EV infrastructure provisions for the applicable building type, as specified in Attachment 4. Only State minimum standards will be required for nonresidential grocery, retail, or warehouses planning for offstreet medium-heavy duty vehicles. This component of the model code exceeds the CALGreen provisions for renovations by requiring single-family homes to be EV Ready if the project is upgrading the main electrical service panel. For both multifamily and nonresidential renovations, the model code also exceeds CALGreen provisions by requiring designated electrical capacity for 20% of onsite parking spaces to be EV Capable if modifying the main electrical service panel. Additionally, for multifamily and nonresidential renovations that modify the parking lot surface, either conduit must be added to a minimum of 50% of exposed parking spaces, or a minimum 5% EV Charging Stations (EVCS) must be installed to parking spaces requiring any combination of Level 2 and Direct Current Fast Charging EV Supply Equipment (EVSE), except at least one Level 2 EVSE must be provided. The 2022 Building Code misses the opportunity to maximize this moment when parking lot surfaces and/or service panels are upgraded. By requiring the installation of EV infrastructure at time of parking lot upgrades, developers can fully benefit from construction savings and install valuable amenities for their occupants.
Staff recommends this component of the model code be included in the 2022 Building Code adoption with the following revisions:
• Only apply CALGreen Tier 1 EV infrastructure provisions to new construction for single-family buildings and nonresidential buildings.
• For new multifamily building construction, apply the following requirement:
o Of the total parking spaces, 15% must be Level 2 EVCS and 85% must be Low Power Level 2 EV Ready.
This requirement would ensure that 100% of units in any new multifamily building with parking spaces have access to charging capabilities. In contrast, CALGreen Tier 1 EV infrastructure provisions only provide access to charging capabilities for 35% of parking spaces (if less than 20 units) and 45% of parking spaces (if greater than 20 units). The requirement is modeled off of the “High Power Option” in the Bay Area EV Reach Codes developed by Peninsula Clean Energy (PCE), Silicon Valley Clean Energy (SVCE), and East Bay Community Energy (EBCE) (Attachment 5). • For multifamily and nonresidential renovations that modify the service panel, revise the model code requirement such that electrical capacity must be added for 20% of onsite parking spaces to be Level 2 EV Ready.
6 • For multifamily and nonresidential renovations that modify the parking lot surface, revise the model code requirement such that conduit must be added to a minimum of 25% of exposed parking spaces and a minimum 5% of EVCS must be installed to parking spaces requiring any combination of Level 2 and Direct Current Fast Charging EVSE, except at least one Level 2 EVSE must be provided.
These recommended revisions are aligned with what County staff will likely recommend for their 2022 Building Code adoption, and several other Bay Area jurisdictions (e.g., Berkeley, Half Moon Bay, Albany) will be deviating from the CALGreen EV infrastructure provisions for their own 2022 Building Code adoption in order to provide greater access to charging capabilities in multifamily buildings. If included as part of the 2022 Building Code adoption, these EV charging infrastructure requirements will allow the Town to make significant progress in terms of EV adoption and implementation of Measure T-1: Zero Emission Vehicles in the CAP, which represents the largest potential for emissions reductions by 2030 (i.e., a potential 10,648 MTCO2e emissions reduction if 100% of passenger vehicles used by Fairfax residents and businesses are ZEVs in 2030 and all charge with 100% GHG-free electricity). As it relates to EV reach codes, Measure T-1 specifically calls for:
• Implementing more stringent requirements for pre-wiring new single-family and multifamily construction, as well as substantial remodels, for EV chargers. • Requiring new and remodeled commercial projects to install a minimum number of electric vehicle chargers for use by employees, customers, and residents.
Under Measure E-1: Ordinances for Construction of Energy-Efficient Buildings in the CAP, it calls for adopting the most aggressive reach codes in the County and State. Staff believes that if all the requirements discussed in the previous sections are included in the adoption of the 2022 Building Code, this will represent one of the most aggressive reach codes in both the County and State while also balancing other important considerations such as the need to build more affordable housing and ensure equity when implementing climate solutions. If Council directs staff to include the proposed reach code in the 2022 Building Code, staff will evaluate the effectiveness of this reach code once implemented to determine if more stringent requirements may be required in the future to meet the Town’s climate goals. Finally, staff will continue to promote existing financial incentives for energy efficiency and electrification renovations provided by BayREN, Electrify Marin, and other organizations, as well as develop rebate programs and other incentives to encourage residents and businesses to install electric appliances.
