STAFF REPORT
Meeting: City Council - Nov 15 2022
Agenda Heading: CONSENT CALENDAR
Staff Contact: Diana Perkins, City Planner
Department: City Planner
Title: Adoption of a Resolution Summarily Vacating Right of Way at 15255 and 15297 Karl Avenue.

Recommendation(s):

Background Information:

The City Council accepted a dedication for use as right-of-way from the property owners of 15255 and 15297 Karl Avenue on July 21, 1964. At that time, these two properties were subdivided and the right-of-way dedication was required as it was envisioned that Karl Avenue would need to be widened.

Analysis:

The owners of the properties at 15255 and 15297 Karl Avenue have requested that the City vacate the ten-foot-wide road dedications, recorded in the Office of the Recorder of the County of Santa Clara, on July 30, 1964, in Book 6602 at Page 204. This dedication was provided at the time these two lots were subdivided and the street dedication was for potential widening of Karl Avenue. Karl Avenue has not been widened and such dedications were not required for other lots along Karl Avenue. Therefore, this dedication has not been used for its purpose since acquisition and is not necessary for any future public purpose. The 10-foot-wide road dedications along these two parcels can be vacated in accordance with the summary vacation proceeding authorized by the California Streets and Highways Code section 8330, because it is excess right-of-way not required for street or highway purposes. (Gov. Code 8334.) Additionally, there are no in-place public utility facilities which would prohibit the use of summary vacation proceedings.

California Environmental Quality Act:

This project is categorically exempt from CEQA pursuant to CEQA Guidelines section 15305 – minor alterations in land use limitations.

STAFF REPORT
Meeting: City Council - Nov 15 2022
Agenda Heading: PUBLIC HEARINGS
Staff Contact: Diana Perkins, City Planner
Department: City Planner
Title: Public Hearings on Adoption of:
(1) Ordinance No. NS-230, an Ordinance of the City Council of the City of Monte Sereno Amending Title 9 of the Monte Sereno Municipal Code to Adopt by Reference Title 24 of the California Code of Regulations, 2022 California Building Standards Code, Including California Residential Code, California Plumbing Code, California Electrical Code, California Mechanical Code, California Green Building Code, California Energy Code, California Fire Code and the California Existing Building Code Subject to the Specified Local Amendments.
(2) Ordinance No. NS-231, An Ordinance of the City Council of the City of Monte Sereno Amending Title 9, Buildings and Construction, of the Monte Sereno Municipal Code to Add Sections 9.01.040 and 9.01.060 to Enact Specified Local Amendments to the California Energy Code, 2022 Edition, Title 24, Part 6 and the California Green Building Standards Code, 2022 Edition, Title 24, Part 11 of the California Code of Regulations.

The City of Monte Sereno is currently utilizing the 2019 editions of the California Building Standards Code, Title 24 of the California Code of Regulations, as amended by Title 9 of the Monte Sereno Municipal Code. These codes are updated every three years by the respective code development organization bodies such as the International Code Council (ICC), International Association of Plumbing and Mechanical Officials (IAPMO), and the National Fire Protection Association (NFPA). Proposed changes are submitted to the various code groups, reviewed by the code development committees, and voted on by the general membership at the annual meetings. If a proposed code change is approved, it becomes part of the next edition of

Page 41 of 233 ends

the code. In California, the California Building Standards Commission then has authority to further amend and then adopt the codes, which become uniform state law. Once the Commission adopts the codes, local agencies have 180 days to adopt the codes and must enforce the codes.

The 2022 Building Standards Codes have been adopted by the Building Standards Commission and will go into effect on January 1, 2023.

Local agencies are also allowed to make some modifications to the codes as adopted by the Building Standards Commission in accordance with provisions under state law. Local jurisdictions within the State are allowed to amend the codes further based on topographical, climatic or geological conditions as long as the code changes are comparable to or more restrictive than the State codes. If local amendments are not re-adopted before January 1, 2023, the version adopted by the Building Standards Commission applies by default and the local agencies are required to enforce those codes.

The City Council introduced Ordinance Nos. NS-230 and NS-231 at the November 1, 2022 meeting. Pursuant to Government Code 50022.3, there shall be a public hearing scheduled after the first reading of the title of the adopting ordinances. Therefore, the adoption of these two ordinances has been placed on the New Business portion of the City Council meeting agenda.

Analysis:

The purpose of the Building Standards Code, which includes all of the building codes and fire code, is to safeguard life, safety, health, property, and the public welfare through regulation and control of the use, occupancy, location, and maintenance of structures, and the quality of materials used in their construction. To assure compliance with the codes, City staff reviews plans and conducts inspections of projects.

Since 1994, the City has been working with the Tri-chapter Uniform Code Committee (TUCC), in an effort to provide consistency to all local amendments of the codes. TUCC is a subcommittee of the ICC-Peninsula Chapter, comprised mainly of building officials and plan checkers from numerous jurisdictions in the Bay Area, whose goal is to assist the design and construction community by developing consistent code interpretations among the jurisdictions and maintaining high standards with regard to life and safety issues. The TUCC makes recommendations to the Peninsula Chapter with regard to amendments to the various codes.

The members of the Peninsula Chapter vote on the proposed amendments for adoption.

Similarly, the Santa Clara County Fire Marshals Association meets and reviews the codes to determine if local amendments are warranted and to obtain uniformity in requirements in the area. In support of this goal, staff is recommending adoption of the codes and amendments as agreed upon by the members of TUCC, the ICC-Peninsula Chapter and the Santa Clara County Fire Marshals Association.

The proposed amendments are justified based on the local topographical, climatic and geological conditions that affect the area. The City of Monte Sereno experiences low humidity, high winds and warm temperatures during the summer months creating conditions which are particularly conducive to the ignition and spread of grass, brush and structure fires. Additionally, the City of Monte Sereno is geographically situated adjacent to active earthquake faults capable of producing substantial seismic events. The occurrence of a major earthquake would

Page 42 of 233 ends

significantly impact the ability of fire crews to respond to emergencies should the roadways be substantially damaged. In addition, fire suppression capabilities would be severely limited should the water system be extensively damaged during the seismic event. Therefore, mitigation measures are necessary such as: automatic fire suppression systems, communications systems, access to buildings, seismic protection, safety controls and other safeguards in order to minimize the risks to citizens, firefighters and property due to the severity of the fire threat and potential response delays.

Reach Codes
A reach code is a local building code amendment that “reaches” beyond the state minimum requirements for energy efficiency. During the last Building and Fire Code adoption cycle in 2019, the City Council adopted reach codes as amendments to the building codes which required that electric infrastructure (wiring, circuits, and panel capacity) be provided when a gas-fueled water heater, space heating equipment, or stove is installed in new construction.

Additionally, requirements for the pre-wiring for battery storage in new construction was also adopted at that time. Each of these items previously adopted by the City Council as reach codes are mandated in the upcoming 2022 building codes, so these do not need to be included in the local ordinance.

At the September 20, 2022 meeting, the City Council reviewed and discussed potential reach codes for this code adoption cycle and directed staff to include the following for new construction:
• Provide one Level 2 EV-Ready receptacle and associated infrastructure at each enclosed garage parking space, with a maximum of two, and one outside of the garage. • Require all indoor appliances, with the exception of cooking appliances, be electric.

Outdoor appliances can be electrical or gas-fueled.
• Provide an automatic hot water recirculating system.

These items are included in the draft ordinance in Attachment 2.

The proposed reach codes meet the requirements of the California Energy Commission for cost-effectiveness, and are also a cost-effective approach for constituents, contractors, and developers pursuing new construction within the city limits. A copy of the cost effectiveness study is attached to the Ordinance No. NS-231 in Attachment 2 to this staff report.

Public Noticing:

ORDINANCE NO. NS-230

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF MONTE SERENO AMENDING TITLE 9 OF THE MONTE SERENO MUNICIPAL CODE TO ADOPT BY REFERENCE TITLE 24 OF THE CALIFORNIA CODE OF REGULATIONS, 2022

CALIFORNIA BUILDING STANDARDS CODE, INCLUDING CALIFORNIA

RESIDENTIAL CODE, CALIFORNIA PLUMBING CODE, CALIFORNIA ELECTRICAL

CODE, CALIFORNIA MECHANICAL CODE, CALIFORNIA GREEN BUILDING CODE,

CALIFORNIA ENERGY CODE, CALIFORNIA FIRE CODE AND THE CALIFORNIA

EXISTING BUILDING CODE SUBJECT TO THE SPECIFIED LOCAL AMENDMENTS WHEREAS, each city in California is required to adopt the California Building Standards Code and is authorized to do so by reference under Health and Safety Code section 17922 and Government Code section 50022.2; and
WHEREAS, pursuant to Health and Safety Code section 17958.7, each city in California may enact local amendments to the California Building Standards upon making findings that local amendments are reasonably necessary because of local climatic, geological or topographical conditions;

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF MONTE SERENO DOES ORDAIN AS FOLLOWS:

SECTION 1. The City Council hereby makes the following findings and determinations:

A. The entire Silicon Valley is located in seismic zone D & E. Gypsum wallboard and exterior portland cement plaster have performed poorly during the recent California seismic events. The shear values of gypsum wallboard and portland cement stucco contained in the code are based on mono-directional testing. It is appropriate to limit the use of these products until cyclic load testing is performed and evaluated.

Historically, fire has been a real danger in the aftermath of earthquake damage, and the occurrence of a major earthquake would significantly impact the ability of fire crews to respond to emergencies should roadways be damaged, or if the water system be extensively damaged during a seismic event.

Page 45 of 233 ends

2 OAK #4886-2943-5192 v5
summer months creating conditions which are particularly conducive to the ignition and spread of grass, brush, and structure fires;
D. The streets within the City are a combination of public and private roadways, which due to the many hills and canyons are narrow and often dead end creating additional problems for vehicles and personnel to respond in emergency situations such as a fire.

E. Due to these climatic, geological, geographical, and topographical conditions, mitigation measures are necessary such as automatic fire suppression systems, communications systems, access to buildings, seismic protection, safety controls for hazardous materials, and other safeguards are necessary in order to minimize the risks to citizens, firefighters, and property resulting from the severity of a fire threat and potential delays in responding to such threats.

SECTION 2. Based on the local climatic, geological, and topographical conditions, identified in Section 1 of this ordinance, the City of Monte Sereno determines and finds that the adoption of specified codes in the Title 24 Building Standards with the following local amendments is reasonably necessary, and that Chapter 9.01 of Title 9 of the Monte Sereno Municipal Code is repealed and replaced with local amendments to read in its entirety as follows:

ORDINANCE NO. NS-231

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF MONTE SERENO AMENDING TITLE 9, BUILDINGS AND CONSTRUCTION, OF THE MONTE SERENO MUNICIPAL CODE TO ADD SECTIONS 9.01.040 AND 9.01.060 TO ENACT SPECIFIED LOCAL AMENDMENTS TO THE CALIFORNIA ENERGY CODE, 2022 EDITION, TITLE 24, PART 6 AND THE CALIFORNIA GREEN BUILDING STANDARDS CODE, 2022 EDITION, TITLE 24, PART 11 OF THE CALIFORNIA

CODE OF REGULATIONS
WHEREAS, each city in California is required to adopt the California Building Standards Code and is authorized to do so by reference under Health and Safety Code section 17922 and Government Code section 50022.2; and
WHEREAS, pursuant to Health and Safety Code section 17958.7, each city in California may enact local amendments to the California upon making findings that local amendments are reasonably necessary because of local climatic, geological or topographical conditions; and
WHEREAS, Public Resources Code section 25402.1(h) (2) and section 10-106 of the Building Energy Efficiency Standards establish a process which allows local adoption of amendments to statewide energy standards that are more stringent than the statewide standards (“Reach Codes”) if they are found to be cost effective, and require buildings to be designed to consume no more energy than permitted by Title 24 and approved by the California Energy Commission; and
WHEREAS, a cost effectiveness study was prepared by Frontier Energy Inc., Misti Bruceri and Associates, LLC entitled “2022 Cost-effectiveness Study: Single Family New Construction” which found that certain residential new construction to be cost effective, especially for cooking, water heating and clothes drying equipment, in all California climate zones and the study is sufficient to justify Monte Sereno reach code requirements and the cost effectiveness analysis required by the California Energy Commission for the local amendments to the California Energy Code; and WHEREAS, the adopted Building Code includes voluntary sustainability measures known as Cal Green Tier 1 and Tier 2.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF MONTE SERENO DOES ORDAIN AS FOLLOWS:

SECTION 1. The City Council hereby makes the following findings and determinations:

Page 92 of 233 ends

Page 2 of 5 ends

OAK #4894-2205-7784 v2
A. The entire Silicon Valley is located in seismic zone D & E. Gypsum wallboard and exterior portland cement plaster have performed poorly during the recent California seismic events. The shear values of gypsum wallboard and portland cement stucco contained in the code are based on mono-directional testing. It is appropriate to limit the use of these products until cyclic load testing is performed and evaluated.

B. The City of Monte Sereno is located in seismic zone D & E. The increased possibility of earthquake activity in the area can affect the availability of emergency services due to damage to the water systems, damage to roadways, debris on roadways and the low priority of single-family homes in emergency conditions. Historically, fire has been a real danger in the aftermath of earthquake damage, and the occurrence of a major earthquake would significantly impact the ability of fire crews to respond to emergencies should roadways be damaged, or if the water system be extensively damaged during a seismic event.

C. Monte Sereno is located in a hilly area with many canyons and areas of dense wildland vegetation. The area is subject to periods of low rainfall, frequent periods of low humidity and high temperatures, and is subject to gusty winds up to 30 mph. These conditions present an increased fire danger and increase the possibility of fire spreading to other properties that are not easily or directly accessible from the point of origin. The City also experiences low humidity, high wind, and warm temperatures during the summer months creating conditions which are particularly conducive to the ignition and spread of grass, brush, and structure fires;
D. The streets within the City are a combination of public and private roadways, which due to the many hills and canyons are narrow and often dead end creating additional problems for vehicles and personnel to respond in emergency situations such as a fire.

E. Over the next century, increasing levels of atmospheric greenhouse gas concentrates are expected to result in global temperature increases, causing a variety of local changes, including extreme weather conditions, sea level rise, more frequent heat waves and extended period of drought. Increased heat as a result of climate change can have a local impact on the health, safety, and welfare of the City's population, especially those without resources to purchase air conditioning, the elderly, disabled, or those with children. Failure to address and substantially reduce Greenhouse Gas creates an increased risk to the health, safety and welfare of the City residents;
F. Due to these climatic, geological, geographical, and topographical conditions, mitigation measures are necessary such as automatic fire suppression systems, communications systems, access to buildings, seismic protection, safety controls for hazardous materials, and other safeguards are necessary in order to minimize the risks

Page 3 of 5 ends

OAK #4894-2205-7784 v2
to citizens, firefighters, and property resulting from the severity of a fire threat and potential delays in responding to such threats.

G. Cost Effectiveness. The City Council finds that the overview of the cost effectiveness study and the study itself, which is attached hereto and incorporated herein as Exhibit A to this ordinance is sufficient to justify Monte Sereno reach code requirements contained in this ordinance and demonstrate that the local amendments to the California Energy Code contained in this ordinance are cost effective and will require buildings to consume no more energy than permitted by Title 24.

H. The local amendments to the California Energy Code and Green Building Standards Code in this ordinance are reasonably necessary because of the local climatic, geological, and topographical conditions identified in this section.

SECTION 2. Section 9.01.040 of Chapter 9.01 of the Monte Sereno Municipal Code is enacted to read in entirety as follows:

9.01.040 Amendments to the California Code Of Regulations Title 24, Part 6, 2022 California Energy Code.

Cost-Effectiveness Analysis: Single Family New Construction Executive Summary
1 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 Executive Summary
The California Codes and Standards (C&S) Reach Codes program provides technical support to local governments considering adopting a local ordinance (reach code) intended to support meeting local and/or statewide energy efficiency and greenhouse gas reduction goals. The program facilitates adoption and implementation of the code when requested by local jurisdictions by providing resources such as cost-effectiveness studies, model language, sample findings, and other supporting documentation.

This report documents cost-effectiveness analysis results for traditional new detached single family and detached accessory dwelling unit (ADUs) building types. It evaluates mixed fuel and all-electric package options in all sixteen California climate zones (CZs). Packages include combinations of efficiency measures, on-site renewable energy, and battery energy storage.

The following summarizes key results from the study:
• All-electric packages have lower GHG emissions than mixed-fuel packages in all cases, due to the clean power sources currently available from California’s power providers. • The Reach Codes Team found all-electric new construction to be feasible and cost effective based on TDV in all cases. In many cases all-electric code minimum construction results in an increase in utility costs and is not cost-effective On-Bill. Some exceptions include the SMUD and CPAU territories where lower electricity rates relative to natural gas rates result in lower overall utility bills. • The 2022 Title 24 Code’s new source energy metric combined with the heat pump baseline encourage allelectric construction, providing an incentive that allows for some amount of prescriptively required building efficiency to be traded off. This compliance benefit for all-electric homes highlights a unique opportunity for jurisdictions to incorporate efficiency into all-electric reach codes. Efficiency and electrification have symbiotic benefits and are both critical for decarbonization of buildings. As demand on the electric grid is increased through electrification, efficiency can reduce the negative impacts of additional electricity demand on the grid, reducing the need for increased generation and storage capacity, as well as the need to upgrade upstream transmission and distribution equipment. The Reach Codes Team recommends that jurisdictions adopting an all-electric reach code for single family buildings also include an efficiency requirement with EDR2 margins consistent with the all-electric code minimum package.
• The code compliance margins for the ADU all-electric code minimum package are lower than for the single family prototype and code compliance can be more challenging for smaller dwelling units. As a result, the Reach Codes Team does not recommend an additional efficiency requirement for all-electric ADU ordinances. • Electrification combined with increased PV capacity results in utility cost savings and was found to be On-Bill cost effective in all cases. These results were based on today’s net energy metering rules and do not account for future changes to utility agreements, which are expected to decrease the value of PV to the consumer. • For jurisdictions interested in a reach code that allows for mixed fuel buildings, the mixed fuel efficiency, PV, and battery package was found to be cost effective based on TDV in all cases. Cost effectiveness was marginal because of the high cost of the battery system. EDR2 margins ranged from 7 to 30 for the costeffective packages. • Applying the CARE rates has the overall impact to increase utility cost savings for an all-electric building compared to a code compliant mixed fuel building, improving On-Bill cost-effectiveness.

This report presents measures or measure packages that local jurisdictions may consider adopting to achieve energy savings and emissions reductions beyond what will be accomplished by enforcing minimum state requirements, the 2022 Building Energy Efficiency Standards (Title 24, Part 6), effective January 1, 2023.

Local jurisdictions may also adopt ordinances that amend different Parts of the California Building Standards Code or may elect to amend other state or municipal codes. The decision regarding which code to amend will determine the specific requirements that must be followed for an ordinance to be legally enforceable. For example, jurisdictions that only want to require all-electric construction may amend Part 11 instead of Part 6 of the CA Building Code requiring

Reach codes that amend Part 6 of the CA Building Code and require energy performance beyond state code minimums must demonstrate the proposed changes are cost-effective and obtain approval from the Energy Commission. Although a cost-effectiveness study is only required to amend Part 6 of the CA Building Code, this study provides valuable context for jurisdictions pursuing other ordinance paths to understand the economic impacts of any policy decision. This study documents the estimated costs, benefits, energy impacts and greenhouse gas emission reductions that may result from implementing an ordinance based on the results to help residents, local leadership, and other stakeholders make informed policy decisions.

Cost-Effectiveness Analysis: Single Family New Construction Introduction
3 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 1 Introduction
This report documents cost-effective combinations of measures that exceed the minimum state requirements, the 2022 Building Energy Efficiency Standards, effective January 1, 2023, for newly constructed single family buildings. This report was developed in coordination with the California Statewide Investor-Owned Utilities (CA IOUs) Codes and Standards Program, key consultants, and engaged cities—collectively known as the Reach Codes Team.

The analysis considers traditional detached single family and detached accessory dwelling unit (ADUs) building types and evaluates mixed fuel and all-electric package options in all sixteen California climate zones (CZs). 1 Packages include combinations of efficiency measures, on-site renewable energy, and battery energy storage.

The California Building Energy Efficiency Standards Title 24, Part 6 (Title 24) (California Energy Commission, 2021a) is maintained and updated every three years by two state agencies: the California Energy Commission (Energy Commission) and the Building Standards Commission (BSC). In addition to enforcing the code, local jurisdictions have the authority to adopt local energy efficiency ordinances—or reach codes—that exceed the minimum standards defined by Title 24 (as established by Public Resources Code Section 25402.1(h)2 and Section 10-106 of the Building Energy Efficiency Standards). Local jurisdictions must demonstrate that the requirements of the proposed ordinance are costeffective and do not result in buildings consuming more energy than is permitted by Title 24. In addition, the jurisdiction must obtain approval from the Energy Commission and file the ordinance with the BSC for the ordinance to be legally enforceable.

The Department of Energy (DOE) sets minimum efficiency standards for equipment and appliances that are federally regulated under the National Appliance Energy Conservation Act, including heating, cooling, and water heating equipment (E-CFR, 2020). Since state and local governments are prohibited from adopting higher minimum efficiencies than the federal standards require, the focus of this study is to identify and evaluate cost-effective packages that do not include high efficiency heating, cooling, and water heating equipment. High efficiency appliances are often the easiest and most affordable measures to increase energy performance. While federal preemption limits reach code mandatory requirements for covered appliances, in practice, builders may install any package of compliant measures to achieve the performance requirements.

Cost-Effectiveness Analysis: Single Family New Construction Methodology and Assumptions
4 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 2 Methodology and Assumptions

2.1 Analysis for Reach Codes
This section describes the approach to calculating cost-effectiveness including benefits, costs, metrics, and utility rate selection.

2.1.1 Modeling
The Reach Codes Team performed energy simulations using software approved for 2022 Title 24 Code compliance analysis, CBECC-Res 2022.1.0.

The general approach applied in this analysis is to evaluate performance and determine cost effectiveness of various energy efficiency upgrade measures, individually and as packages, in single family buildings. Using the 2022 baseline as the starting point, prospective measures and packages were identified and modeled in each of the prototypes to determine the projected energy (therm and kWh) and compliance impacts. A large set of parametric runs were conducted to evaluate various options and develop packages of measures that met or exceeded minimum code performance. The analysis utilized a Python based parametric tool to automate and manage the generation of CBECCRes input files. This allowed for quick evaluation of various efficiency measures across multiple climate zones and prototypes and improved quality control. The batch process functionality of CBECC-Res was utilized to simulate large groups of input files at once.

2.1.2 Cost-Effectiveness

2.1.2.1 Benefits
This analysis used two different metrics to assess cost effectiveness of the proposed upgrades. Both methodologies require estimating and quantifying the incremental costs and energy savings associated with each energy efficiency measure. The main difference between the methodologies is the manner in which they value energy and thus the cost savings of reduced or avoided energy use:

Utility Bill Impacts (On-Bill): Customer-based lifecycle cost (LCC) approach that values energy based upon estimated site energy usage and customer utility bill savings using today’s electricity and natural gas utility tariffs. Total savings are estimated over a 30-year duration and include discounting of future costs and energy cost inflation.

Time Dependent Valuation (TDV): Energy Commission LCC methodology, which is intended to capture the total value or cost of energy use over 30 years. This method accounts for long-term projected costs, such as the cost of providing energy during peak periods of demand and other societal costs, such as projected costs for carbon emissions, as well as grid transmission and distribution impacts. This metric values energy use differently depending on the fuel source (natural gas, electricity, and propane), time of day, and season. For example, electricity used (or saved) during peak periods has a much higher value than electricity used (or saved) during off-peak periods due to the less inefficient energy generation sources providing peak electricity (Horii, Cutter, Kapur, Arent, & Conotyannis, 2014).

This is the methodology used by the Energy Commission in evaluating cost effectiveness for efficiency measures in Title 24, Part 6.

2.1.2.2 Costs
The Reach Codes Team assessed the incremental costs of the measures and packages over a 30-year lifecycle.

Incremental costs represent the equipment, installation, replacements, and maintenance costs of the proposed measure relative to the 2022 Title 24 Standards minimum requirements or standard industry practices. Present value of replacement cost is included for measures with lifetimes less than the evaluation period.

In calculating On-Bill cost effectiveness, incremental first costs were assumed to be financed into a mortgage or loan with a 30-year loan term and four percent interest rate. Financing was not applied to future replacement or maintenance costs. In calculating TDV cost effectiveness, incremental first costs were not assumed to be financed into a mortgage or loan.

2.1.2.3 Metrics
Cost-effectiveness is presented using net present value (NPV) and benefit-to-cost (B/C) ratio metrics.

NPV Savings: The lifetime NPV savings is reported as a cost-effectiveness metric, Equation 1 demonstrates how this is calculated. If the net savings of a measure or package is positive, it is considered cost-effective. Negative savings represent net costs.

B/C Ratio: Ratio of the present value (PV) of all benefits to the present value of all costs over 30 years (PV benefits divided by PV costs). The criteria benchmark for cost effectiveness is a B/C ratio greater than one. A value of one indicates the NPV of the savings over the life of the measure is equivalent to the NPV of the lifetime incremental cost of that measure. A value greater than one represents a positive return on investment. The B/C ratio is calculated according to Equation 2.

Equation 1
𝑁𝑁𝑁𝑁𝑁𝑁 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 = 𝑜𝑜𝑜𝑜 𝑙𝑙 𝑙𝑙𝑙𝑙 𝑙𝑙𝑙𝑙 𝑏𝑏 − 𝑜𝑜𝑜𝑜 𝑙𝑙 𝑙𝑙𝑙𝑙 𝑙𝑙𝑙𝑙 𝑐𝑐 Equation 2
𝐵𝐵 − − 𝐶𝐶 𝑅𝑅 = 𝑜𝑜𝑜𝑜 𝑙𝑙 𝑙𝑙𝑙𝑙 𝑙𝑙𝑙𝑙 𝑏𝑏
𝑜𝑜𝑜𝑜 𝑙𝑙 𝑙𝑙𝑙𝑙 𝑙𝑙𝑙𝑙 𝑐𝑐
Improving the efficiency of a project often requires an initial incremental investment. In most cases the benefit is represented by annual On-Bill utility or TDV savings, and the cost is represented by incremental first cost and replacement costs. However, some packages result in initial construction cost savings (negative incremental cost), and either energy cost savings (positive benefits), or increased energy costs (negative benefits). In cases where both construction costs and energy-related savings are negative, the construction cost savings are treated as the ‘benefit’ while the increased energy costs are the ‘cost.’ In cases where a measure or package is cost-effective immediately (i.e., upfront construction cost savings and lifetime energy cost savings), B/C ratio cost effectiveness is represented by “>1”.

The lifetime costs or benefits are calculated according to Equation 3.

Equation 3
𝑜𝑜𝑜𝑜 𝑙𝑙 𝑙𝑙𝑙𝑙 𝑙𝑙𝑙𝑙 𝑐𝑐 𝑜𝑜𝑜𝑜 𝑏𝑏 = �(𝐴𝐴 𝐴𝐴 𝑐𝑐 𝑜𝑜𝑜𝑜 𝑏𝑏 )𝑡𝑡

𝑡𝑡=0
Where:
• n = analysis term in years
• r = discount rate
The following summarizes the assumptions applied in this analysis to both methodologies. • Analysis term of 30 years
• Real discount rate of three percent
TDV is a normalized monetary format and there is a unique procedure for calculating the present value benefit of TDV energy savings. The present value of the energy cost savings in dollars is calculated by multiplying the TDV savings (reported by the CBECC-Res simulation software) by a NPV factor developed by the Energy Commission (see (Energy + Environmental Economics, 2020)). The 30-year residential NPV factor is $0.173/kTDV kBtu for the 2022 code cycle.

2.1.3 Utility Rates
In coordination with the CA IOU rate team (comprised of representatives from Pacific Gas and Electric (PG&E), Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E)) and two Publicly-Owned-Utilities (POUs) (Sacramento Municipal Utility District (SMUD) and City of Palo Alto Utilities (CPAU)), the Reach Codes Team determined appropriate utility rates for each climate zone in order to calculate utility costs and determine On-Bill cost effectiveness for the proposed measures and packages. The utility tariffs, summarized in Table 1, were determined based on the most prevalent active rate in each territory. Utility rates were applied to each climate zone based on the predominant IOU serving the population of each zone, with a few climate zones evaluated multiple times under different utility scenarios. Climate Zones 10 and 14 were evaluated with both SCE/SoCalGas and SDG&E tariffs since each utility has customers within these climate zones. Climate Zone 5 is evaluated under both PG&E and SoCalGas natural gas rates. Two POU or municipal utility rates were also evaluated: SMUD in Climate Zone 12 and CPAU in Climate Zone 4.

First-year utility costs were calculated using hourly electricity and natural gas output from CBECC-Res and applying the utility tariffs summarized in Table 1. Annual costs were also estimated for customers eligible for the CARE tariff discounts on both electricity and natural gas bills. Appendix 7.2 Utility Rate Schedules includes details of each utility tariff. For cases with PV generation, the approved NEM2 tariffs were applied along with minimum daily use billing and mandatory non-bypassable charges. Future changes to the NEM tariffs are likely and the California Public Utilities Commission (CPUC) has issued a proposed decision with suggested changes that is expected to be finalized in 2022. 2 The ADU was assumed to have separate electric and gas meters from the main house.

Table 1. Utility Tariffs Used Based on Climate Zone
Climate Zones Electric / Gas Utility Electricity Natural Gas IOUs
1-5,11-13,16 PG&E / PG&E E-TOU Option C G1
5 PG&E / SoCalGas E-TOU Option C GR

POUs
4 CPAU / CPAU E-1 G-2
12 SMUD / PG&E R-TOD (RT02) G1
Utility rates are assumed to escalate over time according to the assumptions from the CPUC 2021 En Banc hearings on utility costs through 2030 (California Public Utilities Commission, 2021a). Escalation rates through the remainder of the 30-year evaluation period are based on the escalation rate assumptions within the 2022 TDV factors. See Appendix 7.2.7 Fuel Escalation Assumptions for details.

2.2 Greenhouse Gas Emissions
The analysis reports the greenhouse gas (GHG) emission estimates based on assumptions within CBECC-Res. There are 8,760 hourly multipliers accounting for time dependent energy use and carbon based on source emissions, including renewable portfolio standard projections. There are two strings of multipliers—one for Northern California 2 https://www.cpuc.ca.gov/nemrevisit

2.3 Energy Design Rating
The 2019 Title 24 Code introduced California’s Energy Design Rating (EDR) as the primary metric to demonstrate compliance with the energy code for single family buildings. This EDR was based on the hourly TDV energy use from a building that is compliant with the 2006 International Energy Conservation Code (IECC) as the Reference Building. The Reference Building has an EDR score of 100 while a zero-net energy (ZNE) home has an EDR score of zero. While the Reference Building is used to set the scale for the rating, the Proposed Design is still compared to the Standard Design based on the Title 24 prescriptive baseline assumptions to determine compliance.

In the 2022 Title 24 Code a second new EDR metric was introduced based on hourly source energy. The two EDR metrics are described below:
• EDR1 is calculated based on source energy.
• EDR2 is calculated based on TDV energy.

Furthermore, EDR2 is composed of two components for compliance purposes. The Efficiency EDR2 which represents the energy efficiency features of a home. The PV/Flexibility EDR2 includes the effects of PV and battery storage systems. Total EDR2 combines both the Efficiency and PV/Flexibility impacts. While the Efficiency EDR2 does not include the full impact of a battery system, it can include a self-utilization credit for batteries if certain conditions are met.

For a new, single family building to comply with the 2022 Title 24 Code, three criteria are required:

1. The Proposed EDR1 must be equal to or less than the EDR1 of the Standard Design, and

2. The Proposed Efficiency EDR2 must be equal to or less than the Efficiency EDR2 of the Standard Design, and

3. The Proposed Total EDR2 must be equal to or less than the Total EDR2 of the Standard Design.

This concept, consistent with California’s “loading order” which prioritizes energy efficiency ahead of renewable generation, requires projects meet a minimum Efficiency EDR2 before PV is credited but allows for PV to be traded off with additional efficiency when meeting the Total EDR2. A project may improve on building efficiency beyond the minimum required and subsequently reduce the PV generation capacity necessary to achieve the required Total EDR2.

However, it may not increase the size of the PV system and trade this off with a reduction of efficiency measures.

Results from this analysis are presented as EDR Margin, a reduction in the EDR score relative to the Standard Design.

EDR Margin is a better metric to use than absolute EDR in the context of a reach code because absolute values vary based on the home design and characteristics such as size and orientation. Referencing the margin results in similar requirements across a variety of designs. This approach aligns with how compliance is reported for the 2019 and 2022 Title 24 Code. The EDR Margin is calculated according to Equation 5.

Equation 5
𝐸𝐸 𝑀𝑀 = 𝑆𝑆 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 𝑆𝑆 𝐸𝐸 − 𝑃𝑃 𝐸𝐸
3 CBECC-Res multipliers are the same for CZs 1-5 and 11-13 (Northern California), while there is another set of multipliers for CZs 6-10 and 14-16 (Southern California).

Cost-Effectiveness Analysis: Single Family New Construction Prototypes, Measure Packages, and Costs
8 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 3 Prototypes, Measure Packages, and Costs
This section describes the prototypes and the scope of analysis drawing from previous 2019 Reach Code research where necessary.

3.1 Prior Reach Code Research
In 2019, the Reach Codes Team analyzed the cost-effectiveness of residential single family new construction projects for mixed-fuel and all-electric packages (Statewide Reach Codes Team, 2019). Using this analysis, several cities and counties in California adopted local energy code amendments encouraging or requiring that low-rise residential new construction be all-electric. As there were few changes to the single family requirements, this analysis for the 2022 code cycle leveraged the work completed for the 2019 reports. Initial efficiency packages were based on the final packages from the 2019 research and were revised to reflect measure specifications and costs based on new data.

3.2 Prototype Characteristics
The Energy Commission defines building prototypes which it uses to evaluate the cost-effectiveness of proposed changes to Title 24 requirements. For the 2022 code cycle the Energy Commission used two single family prototypes, both of which were used in this analysis. Additional details on the prototypes can be found in the Alternative Calculation Method (ACM) Approval Manual (California Energy Commission, 2018).

Additionally, a detached new construction ADU prototype was developed to reflect recent trends in California construction related to the high cost of housing (TRC, 2021). ADUs are additional dwelling units typically built on the property of an existing single-family parcel. ADUs are defined as new construction in the energy code when they are ground-up developments, do not convert an existing space to livable space, and are not attached to the primary dwelling. The evaluated prototype is not representative of an attached ADU constructed as an addition to an existing home.

The Reach Codes Team leveraged prior research to define the detached ADU baseline and measure packages. The house size and number of bedrooms were based on data from a survey conducted by UC Berkeley’s Center for Community Innovation (UC Berkeley Center for Community Innovation, 2021). The survey found that the average square footage for new ADUs statewide is 615 square feet and that the majority (61 percent) of new ADUs have one bedroom.

Table 2 describes the basic characteristics of each prototype. The prototypes have equal geometry on all walls, windows and roof to be orientation neutral.

Num. of Stories 1 2 1
Num. of Bedrooms 3 3 1

The Energy Commission’s protocol for the two single family prototypes is to weight the simulated energy impacts by a factor that represents the distribution of single-story and two-story homes being built statewide. This study assumed 50 percent single-story and 50 percent two-story. Simulation results in this study are characterized according to this ratio, which is approximately equivalent to a 2,400-square foot (ft2) house. 4 ADU results are presented separately. 42,400 ft2 = (50% x 2,100 ft2) + (50% x 2,700 ft2)

Cost-Effectiveness Analysis: Single Family New Construction Prototypes, Measure Packages, and Costs
9 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 The methodology used in the analyses for each of the prototypical building types begins with a design that precisely meets the minimum 2022 prescriptive requirements (zero compliance margin). Table 150.1-A in the 2022 Standards (California Energy Commission, 2021a) lists the prescriptive measures that determine the baseline design in each climate zone. Other features are consistent with the Standard Design in the ACM Reference Manual (California Energy Commission, 2022), and are designed to meet, but not exceed, the minimum requirements. Each prototype building has the following features:
• Slab-on-grade foundation.
• Vented attic.
• High performance attic in climate zones where prescriptively required (CZ 4, 8-16) with insulation installed at the ceiling and below the roof deck per Option B. (Refer to Table 150.1-A in the 2022 Standards.) • Ductwork located in the attic.

Table 3 describes additional characteristics as they were applied to the base case energy model in this analysis. In a shift from the 2019 Standards, the 2022 Standards define a prescriptive fuel source for space heating and water heating establishing a heat pump baseline. In each climate zone one heat pump is prescriptively required. In most climate zones the prescriptive base case includes a heat pump water heater and a natural gas furnace for space heating. In Climate Zones 3, 4, 13, and 14 this is reversed, where the base case has a heat pump space heater and natural gas tankless water heater.

HSPF = heating seasonal performance factor. UEF = uniform energy factor. 3 This version of CBECC-Res used in this analysis did not have the capability to directly model ducted HPWHs even though this configuration is called out as the Standard Design in the 2022 ACM (California Energy Commission, 2022). This was modeled by indicating that the tank is located within the conditioned space with the compressor unit located outside. 4 Exception 2 to Section 150.1(c)14 states that “no PV system is required when the minimum PV system size specified by section 150.1(c)14 is less than 1.8 kWdc.” In this analysis this exception is applied based on the sizes calculated per Equation150.1-C of Section 150.1(c)14. The performance software sizes the PV system based on the estimated energy use, which differs slightly from the prescriptive sizing. As a result, the baseline PV capacity from the performance software for Climate Zone 10 is less than 1.8 kWdc.

3.3 Measure Definitions and Costs
Measures evaluated in this study fall into two categories: those associated with general efficiency, onsite generation, and demand flexibility and those associated with building electrification. The Reach Codes Team selected measures based on cost-effectiveness as well as decades of experience with residential architects, builders, and engineers along with general knowledge of the relative consumer acceptance of many measures.

The following sections describe the details and incremental cost assumptions for each of the measures. Incremental costs represent the equipment, installation, replacement, and maintenance costs of the proposed measures relative to the base case. 5 Replacement costs are applied for roofs, mechanical equipment, PV inverters and battery systems over the 30-year evaluation period. Maintenance costs are estimated for PV systems, but not any other measures.

Costs were estimated to reflect costs to the building owner. All costs are provided as present value in 2023 (2023 PV$).

The Reach Codes Team obtained measure costs from distributors, contractors, literature review, and online sources such as Home Depot and RS Means. Contractor markups are incorporated. These are the Reach Codes Team best estimate of average costs statewide. However, it's recognized that local costs may differ, and that inflation and supply chain issues may also impact costs.

3.3.1 Efficiency, Solar PV, and Batteries
Following are descriptions of each of the efficiency, PV, and battery measures evaluated under this analysis and applied in at least one of the packages presented in this report. Table 5 summarizes the incremental cost assumptions for each of these measures.
5 All first costs are assumed to be financed in a mortgage and interest costs due to financing are included in the incremental costs. See Section 2.1.2 for details.

Cost-Effectiveness Analysis: Single Family New Construction Prototypes, Measure Packages, and Costs
11 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 Reduced Infiltration (ACH50): Reduce infiltration in single family homes from the default infiltration assumption of five (5) air changes per hour at 50 Pascals (ACH50) 6 by 40 percent to 3 ACH50. HERS rater field verification and diagnostic testing of building air leakage according to the procedures outlined in the 2022 Reference Appendices RA3.8 (California Energy Commission, 2021b).

Lower U-Factor Fenestration: Reduce window U-factor to 0.24. The prescriptive U-factor is 0.30 in all climates.

Higher SHGC Fenestration: Increase solar heat gain coefficient (SHGC) to 0.50 in climate zones where heating loads dominate. The baseline solar heat gain coefficient (SHGC) applied in the Standard Design is 0.35 in Climate Zones 1, 3, 5, and 16.

Cool Roof: Install a roofing product that’s rated by the Cool Roof Rating Council to have an aged solar reflectance (ASR) equal to or greater than 0.25. Steep-sloped roofs were assumed in all cases. The 2022 Title 24 specifies a prescriptive ASR of 0.20 for Climate Zones 10 through 15.

Increased Ceiling Insulation: Increase ceiling level insulation in a vented attic to R-49 or R-60 insulation.

Slab Insulation: Install R-10 perimeter slab insulation at a depth of 16-inches. This measure doesn’t apply to Climate Zone 16 where slab insulation is required prescriptively.

Low Pressure Drop Ducts: Upgrade the duct distribution system to reduce external static pressure and meet a maximum fan efficacy of 0.35 Watts per cfm. This may involve upsizing ductwork, reducing the total effective length of ducts, and/or selecting low pressure drop components such as filters. Fan watt draw must be verified by a HERS rater according to the procedures outlined in the 2022 Reference Appendices RA3.3 (California Energy Commission, 2021b).

Buried Radial Duct Design: Bury all ductwork in ceiling insulation by laying the ducts across the ceiling joists or inbetween ceiling joists directly on the ceiling drywall. Duct design is based on a radial design where individual ducts are run to each supply register. This allows for smaller diameter ducts, reducing duct losses and more easily meeting fully or deeply buried conditions. 7 Duct burial and duct system design must be verified by a HERS rater according to the procedures outlined in the 2022 Reference Appendices RA3.1.4.1.5 and RA3.1.4.1.6 (California Energy Commission, 2021b). This applies to the single family prototypes only.

R-8 Duct Insulation: Increase duct insulation to R-8 in the climate zones where R-6 insulation is prescriptive.

Ductless Mini-Split Heat Pump: In the ADU prototype replace the ducted split system with a ductless mini-split heat pump with three indoor heads. The system is evaluated as meeting the criteria for the variable capacity heat pump (VCHP) credit, introduced in the 2019 code cycle, which must be verified by a HERS rater according to the procedures outlined in the 2022 Reference Appendices RA3.4.4.3 (California Energy Commission, 2021b). This credit requires verification of refrigerant charge, that all equipment is entirely within conditioned space, that airflow is directly supplied to all habitable space and that wall mounted thermostats serve any zones greater than 150 square feet.

Compact Hot Water Distribution: Design the hot water distribution system to meet minimum requirements for the basic compact hot water distribution credit according to the procedures outlined in the 2022 Reference Appendices RA4.4.6 (California Energy Commission, 2021b). In many single family homes this may require moving the water heater from an exterior to an interior garage wall. CBECC-Res software assumes a 30% reduction in distribution losses for the basic credit.

Solar PV: Installation of on-site PV is required in the 2022 residential code unless an exception is met. The PV sizing methodology in each package was developed to offset annual building electricity use and avoid oversizing which would 6 Whole house leakage tested at a pressure difference of 50 Pascals between indoors and outdoors. 7 The duct systems in the Central Valley Research Homes Project Final Project Report are illustrative of this approach (Proctor, Wilcox, & Chitwood, 2018).

12 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 violate net energy metering (NEM) rules. 8 In all cases, PV is evaluated in CBECC-Res according to the California Flexible Installation (CFI) assumptions.

The Reach Codes Team used two options within the CBECC-Res software for sizing the PV system, described below.

The first option, “Standard Design PV”, was applied in the base case simulations and packages where the PV system size was not changed from the minimum system size required. For the PV packages, the second option was used with a scaling of 100 percent. The Reach Codes Team evaluated an all-electric single family and ADU home with a PV system sized to offset 100 and 90 percent of the total calculated electricity use. Sizing to 100 percent proved to be more cost-effective based on customer utility bills in most cases. As a result, the PV packages were sized to offset 100 percent of electricity use.
• Standard Design PV – the same PV capacity as is required for the Standard Design case9 • Specify PV System Scaling – a PV system sized to offset a specified percentage of the estimated electricity use of the Proposed Design case
One exception to the PV requirement is when the minimum PV system size required is less than 1.8 kWh. This exception applies to the ADU models in Climate Zones 1-9, 12, 14, and 16. For these cases no PV system is required by code and no PV system was modeled in the base case simulations.

Battery Energy Storage: A battery system was evaluated in CBECC-Res with control type set to “Advanced Demand Response Control” and with default efficiencies of 95% for both charging and discharging. The “Advanced Demand Response Control” option assumes the battery system will charge or discharge depending on the needs of the grid. To qualify for the Advanced Demand Response Control the battery system must meet the requirements outlined in the 2022 Reference Appendices JA13.3.3.2 (California Energy Commission, 2021b). 8 NEM rules apply to the IOU territories only.
9 The Standard Design PV system is sized to offset the electricity use of the building loads which are typically electric in a mixed fuel home, which includes all loads except space heating, water heating, clothes drying, and cooking.

Cost-Effectiveness Analysis: Single Family New Construction Prototypes, Measure Packages, and Costs

3.3.2 All-Electric
This analysis compared a code compliant mixed fuel prototype, which uses natural gas for three appliances (cooking, clothes drying and either space heating or water heating), with a code compliant all-electric prototype. In these cases, the relative costs between natural gas and electric appliances, differences between in-house electricity and natural gas infrastructure and the associated infrastructure costs for providing natural gas to the building were included.

To estimate costs the Reach Codes Team leveraged costs from the 2019 reach code cost-effectiveness studies for residential new construction (Statewide Reach Codes Team, 2019) and detached accessory dwelling units (Statewide Reach Codes Team, 2021b), 2022 RS Means, PG&E data, published utility schedules and rules, and online research.

Incremental costs for natural gas infrastructure to a single family building are presented in Table 6 through Table 11.

These costs are applied as cost savings for an all-electric home when compared to a mixed fuel home. This is the component with the highest degree of variability for all-electric homes. These costs are project dependent and may be significantly impacted by such factors as utility territory, site characteristics, distance to the nearest natural gas main and main location, joint trenching, whether work is conducted by the utility or a private contractor, and number of dwelling units per development. All gas utilities participating in this study were solicited for cost information. The CA IOU costs for single family homes presented are based primarily on cost data provided by PG&E.

Table 6 presents assumed gas main distribution line extension costs within gas CA IOU territory. Total distribution line extension costs are based on cost data provided by PG&E for new greenfield development. Total costs are reduced to account for deductions per the Utility Gas Main Extensions rules. 10 These rules categorize distribution line extensions as “refundable” costs, which are offset or subsidized by all other ratepayers. Refundable costs are first subsidized by appliance allowances, which are defined in Table 7. If there are additional costs in excess of the allowances, the developer has the option to either be refunded for the remaining amount over ten years or receive a 50 percent discount at time of application. The latter discount option is assumed in this analysis and is more commonly used by developers (California Public Utilities Commission, 2022). Two scenarios are presented in Table 6 since the appliance allowances differ by type of appliance. One is for the base case home with a prescriptive heat pump space heater which assumes a gas water heater, gas cooking, and gas clothes dryer (Climate Zones 3, 4, 13, and 14). The second is for the base case home with a prescriptive heat pump water heater which assumes a gas furnace, gas cooking, and gas clothes dryer. and a natural gas furnace for space heating (Climate Zones 1, 2, 5 through 12, 15, and 16).

The costs less the deductions were applied under the On-Bill cost-effectiveness methodology. The total costs before the deductions were applied under the TDV cost-effectiveness methodology to better reflect the full cost of gas main extensions since the deductions are subsidized by ratepayers and recovered via revenue from customers. This follows the analysis approach in the 2019 reach code study (Statewide Reach Codes Team, 2019) and was based on input received from the Energy Commission and agreement from the Reach Codes technical advisory team that the approach is appropriate. TDV cost savings impacts extend beyond the customer and account for societal impacts of energy use. Accounting for the full cost of the infrastructure upgrades was determined to be justified when evaluating under the TDV methodology.

The CPUC issued a Proposed Decision in August 2022 that recommends eliminating the subsidies effective July 1, 2023. At the time of publishing this report there had been no ruling on this decision and therefore this analysis assumes the existing rules will remain in place through the 2022 code cycle. A sensitivity analysis of how the results would change if the Proposed Decision were adopted is included in the results of this report. 10 PG&E Rule 15: https://www.pge.com/tariffs/assets/pdf/tariffbook/GAS_RULES_15.pdf.

Table 12 presents incremental costs for natural gas infrastructure for the detached ADU. These costs are directly from the 2019 detached ADU reach code report (Statewide Reach Codes Team, 2021b) and were obtained from interviews and RS Means. For the ADU scenario it’s assumed that natural gas already exists on the lot and is being extended to the location of the ADU typically at the back of the lot. There are incremental cost savings for an all-electric ADU from not extending the natural gas service; however, there is also a small incremental cost for upgrading the electric service to accommodate the additional electrical load. The Reach Codes Team found that a new detached ADU would require that the building owner upgrade the service connection to the lot in both the mixed-fuel ADU design and the all-electric design. The most common size for this upgrade is to upsize the existing panel to 225A, which would not represent an incremental cost from the mixed-fuel project to the all-electric project. Feeder wiring to the ADU and the ADU subpanel will need to be slightly upgraded for the all-electric design. 11 CPAU Schedule G-5 effective 09-01-2019: https://www.cityofpaloalto.org/files/assets/public/utilities/utilitiesengineering/general-specifications/gas-service-connection-fees.pdf

Equipment lifetimes applied in this analysis for the water heating and space conditioning measures are summarized in Table 13. The lifetime for the heat pump, furnace, and air conditioner are based on the Database for Energy Efficient Resources (DEER) (California Public Utilities Commission, 2021b). In DEER, heat pump and air conditioner measures are assigned an effective useful lifetime (EUL) of 15 years and a furnace an EUL of 20 years. The heating and cooling system components are typically replaced at the same time when one reaches the end of its life and the other is near it. Therefore, it is assumed that both the furnace and air conditioner are replaced at the same time at year 17.5, halfway between 15 and 20 years. For HVAC system costing, air-conditioning is included in all cases in both the base case and proposed models. Present value replacement costs are included in the total lifetime incremental costs.

Air Conditioner 17.5

Appliance incremental costs are shown in Table 14 and Table 15. Replacement costs are applied to HVAC and DHW equipment over the 30-year evaluation period. Costs were estimated to reflect costs to the building owner. All costs are provided as present value in 2023 (2023 PV$). Costs due to variations in furnace, air conditioner, and heat pump capacity by climate zone were not accounted for.

The Reach Codes Team determined that the typical first installed cost for electric appliances is similar to that for natural gas appliances. Cost differences include equipment cost and installation, costs for natural gas piping from the meter to the appliance, and costs for electrical wiring to service the appliances.

Space Heater: Typical HVAC incremental costs were based on material costs from the AC Wholesalers website and labor costs from 2022 RS Means. In most cases the Reach Codes Team found that the material costs were slightly higher for the heat pump, but the labor costs were slightly higher for the gas furnace/AC installation. Costs were calculated for capacities ranging from a 2-ton to a 5-ton and the incremental costs used in this study were based on a weighted average of the expected nominal capacities from CBECC-Res autosizing results for the 2,100 square foot prototype. Incremental replacement costs for the heat pump are based on a 17.5-year lifetime for the gas furnace and air conditioner and a 15-year lifetime for the heat pump. Residual value of the gas furnace/AC at the end of the 30-year analysis period was accounted for to represent the remaining life of the equipment.

Cost-Effectiveness Analysis: Single Family New Construction Prototypes, Measure Packages, and Costs
20 localenergycodes.com California Energy Codes & Standards | A statewide utility program 2022-09-12 Water Heater: Various cost sources were reviewed and the Reach Codes Team determined that installed first costs for a garage installed tankless gas water heater and HPWH are very similar and no incremental cost was applied for the equipment and installation (see below for details on costs for gas piping and electrical wiring). This accounts for slightly higher equipment costs for the HPWH but lower installation labor due to the elimination of the combustion gas venting.

Incremental replacement costs account for a 15-year HPWH lifetime and a 20-year lifetime for the gas tankless water heater. Residual value of the gas tankless at the end of the 30-year analysis period was accounted for to represent the remaining life of the equipment. For the ADU analysis the water heater is evaluated within the conditioned space with the supply air ducted from the outside. An HVAC contractor provided a cost estimate for supply air ducting through the wall in an ADU where the water heater is in an interior room adjacent to an exterior wall. The estimated total cost for this was $652.

A high efficiency HPWH that meets the Northwest Energy Efficiency Alliance (NEEA) 12 Tier 3 rating was also evaluated. HPWHs certified to meet NEEA Tier 3 or Tier 4 are the dominant product on the market today. According to NEEA all major HPWH manufacturers are represented in NEEA’s qualified product list 13 and there are only 11 listed products certified as Tier 1 or Tier 2. 14 While the Reach Codes Team evaluated a HPWH that just meets the federal minimum efficiency standards of close to 2.0 UEF to satisfy federal preemption requirements, the Reach Codes Team is not aware of any 2.0 UEF products that are available. The Reach Codes Team was unable to find any of the Tier 1 or Tier2 HPWHs for sale online and was unable to find any products for sale online that were not NEEA Tier 3 or Tier 4 certified. As a result, no incremental cost is assumed for a NEEA Tier 3 product versus a federal minimum efficiency product.

Clothes Dryer and Range: After review of various sources, the Reach Codes Team concluded that the cost difference between gas and electric resistance equipment for clothes dryers and stoves is negligible and that the lifetimes of the two technologies are also similar.

Electric Service Upgrade: The 2022 Title 24 Code requires electric readiness for gas appliances; as a result, the incremental costs to provide electrical service for electric appliances are minimal. The incremental costs accounted for in this study are calculated as the cost to install 220V service for the electric appliances less the cost for the electric ready requirements and for installing 110V service for the comparable gas appliance. Incremental costs are applied for the space heater, water heater, and cooking range. Based on builder surveys, it’s assumed that in a typical mixed fuel home both electric and gas service are provided to the dryer location and therefore no incremental costs for the dryer were applied. Costs assume 50A service for the range and 30A service for the space heater and water heater. Costs are assumed to be the same for the single family and ADU analyses.

In-House Natural Gas Infrastructure (from meter to appliances): Installation cost to run a natural gas line from the meter to the appliance location was estimated at $580 per appliance. These costs were based on material costs from Home Depot and labor costs from 2022 RS Means. The material costs were about 1/3 higher in RS Means than Home Depot, so the Reach Codes Team used the lower costs from Home Depot. The Reach Codes Team conducted a pipe sizing analysis for the two single family and one ADU prototype homes to estimate the length and diameter of gas piping required assuming the home included a gas furnace, gas tankless water heater, gas range, and gas dryer. Total estimated costs were very similar for each of the three prototypes and an average cost per appliance of $580 was determined. Costs are assumed to be the same for the single family and ADU analyses. 12 Based on operational challenges experienced in the past, NEEA established rating test criteria to ensure newly installed HPWHs perform adequately, especially in colder climates. The NEEA rating requires products comply with ENERGY STAR and includes requirements regarding noise and prioritizing heat pump use over supplemental electric resistance heating.

3.4 Measure Packages
The Reach Codes Team evaluated three packages for mixed fuel homes and five packages for all-electric homes for each prototype and climate zone, as described below.

1. All-Electric Code Minimum: This package meets all the prescriptive requirements of the 2022 Title 24 Code. In some instances, the prescriptive minimum package did not comply with code and efficiency measures were added to meet minimum compliance requirements. The added efficiency measures can be found in Table 45 and Table 46.

2. Efficiency Only: This package uses only efficiency measures that don’t trigger federal preemption issues including envelope and water heating or duct distribution efficiency measures.

3. Efficiency + NEEA (Preempted): This package was evaluated for the all-electric homes only and shows an alternative design that applies water heating equipment that is more efficient than federal standards meeting the NEEA Tier 3 rating. The Reach Codes Team considers this more reflective of how builders meet above code requirements in practice.

4. Efficiency + PV: Using the Efficiency Package as a starting point, PV capacity was added to offset most of the estimated electricity use.

5. Efficiency + PV + Battery: Using the Efficiency & PV Package as a starting point, a battery system was added.

For mixed-fuel homes the package of efficiency measures differed from the Efficiency Package in some climate zones to arrive at a cost effective solution.

4.1 2022 Metrics and Compliance
The Reach Codes Team evaluated the compliance impacts of a prescriptive all-electric home as well as a traditional mixed fuel home with four gas appliances (space heating, water heating, cooking, clothes drying). Compliance is relative to the 2022 prescriptive base case home with three gas appliances. The impacts for the single family home and the ADU are presented in Figure 1 and Figure 2, respectively. The all-electric single family home prototype is code compliant with both EDR1 (source energy) and efficiency EDR2 (TDV energy) in all climate zones except Climate Zones 15 and 16. In addition to this climate zone, the all-electric ADU is also not compliant in Climate Zones 4 through 10 and 13 through 15. The four gas appliance single family home is presented in Figure 3. This case is not code compliant in any climate zone.

This analysis illustrates a couple of interesting points. One is that the new 2022 compliance metrics are important drivers encouraging electrification. The compliance penalties assessed the four gas appliance home scenarios are significant and will require deep efficiency measures to overcome. Another is that the 2022 Title 24 Code’s new source energy metric combined with the heat pump baseline encourage all-electric construction, providing a compliance benefit, at least in larger homes, that allows for some amount of prescriptively required building efficiency to be traded off and still comply when using the performance method.

4.2 All-Electric Code Minimum Results
Table 16 shows results for the single family all-electric code minimum case compared to the 2022 baseline. This package reflects the prescriptive minimum requirements except in Climate Zones 15 and 16, where efficiency measures were added to meet minimum code compliance. Utility cost savings are negative, indicating an increase in utility costs for the all-electric building, in all cases except in CPAU and SMUD territories. In all cases the incremental cost is negative, which reflects a cost savings for the all-electric building due to eliminating the gas infrastructure costs. The package is cost effective based on TDV in all cases; however, it’s only cost-effective On-Bill in Climate Zones 4 in CPAU territory, 6, 8, 9, 12 in SMUD territory, and 15.

Table 17 shows the all-electric code minimum case results for the ADU. This package reflects the prescriptive minimum requirements except in Climate Zones 4 through 10 and 13 through 16, where efficiency measures were added to meet minimum code compliance. The conclusions related to cost-effectiveness are similar for the ADU as for the single family analysis.

A summary of measures included in each package is provided in Appendix 7.3 Summary of Measures by Package. The efficiency measures added to the allelectric package to meet minimum code requirements are described in Table 45 and Table 46.

4.3 All-Electric Plus Efficiency, PV, and Battery Results Table 18 and Table 19 compare cost-effectiveness results for the all-electric packages for the single family and ADU prototypes, respectively. In all cases the packages are cost effective based on TDV. On-Bill cost effectiveness generally improves with the addition of efficiency measures, improves significantly with an upsized PV system, and then declines again once batteries are added.

4.4 Mixed Fuel Results
Table 20 and Table 21 show results for the Mixed Fuel Efficiency + PV + Battery package compared to the 2022 baseline for Single Family and ADU, respectively. This package is cost-effective based on TDV everywhere for the single family prototype. It’s TDV cost-effective in most cases for the ADU with the exception of Climate Zones 1 and 10. The package is cost-effective On-Bill for the single family home only in Climate Zone 1. For the ADU the package is costeffective On-Bill in Climate Zones 1, 2, 5, 7, 9, 12 in PG&E territory, 14, and 16. For the climate zones where there is no PV requirement in the base package, the addition of a new PV system substantially reduced utility costs and the high cost-effectiveness of the PV measure helped to offset the high cost of the battery system.
