Building Reach Codes Advancing safer, healthier and more affordable buildings Reach Code Basics Building Model Codes EV Model Codes City Actions GHG Emissions Savings

Purpose Support Cities in meeting climate goals Encourage safer, healthier all-electric buildings within the building code Install EV charging during building construction commensurate with local needs

Guiding Principles Provide cost-effective pathways for both All-Electric and Dual-Fuel (electric + gas) construction Establish the highest possible requirements that are still cost- effective for Dual-Fuel construction. Recommendations must comply within CEC energy code guidelines

Revision History DATE BY EDITS Aug 1 B.H. Version 1 Aug 28 R.R. Corrected EV reference in summary (MUD EV Ready for all units not “spaces”), added subtitle sections and reordered building slides for clarity, added infographic and UC study cost info, slide 6: clarified language, slide 20: added “2019” to column, slide 33: removed confusing reference to “EV Capable being more extensive”, other minor fmt. Sept 3 R.R. Replaced infographic slide 15 for corrected construction savings (DNV GL correction).

I. Reach Code Introductory Slides What are Reach Codes Benefits Model Code Summary Partners for project Timeline

What are Reach Codes? Local enhancements to state code Adopted with current building code cycle Current PCE initiative aimed at improved economic and energy performance Addresses: Building electrification – reduced use of natural gas (methane) and associated emissions Electric vehicle (EV) charging – increased EV readiness

Benefits of Reach Codes Major economic value for residents now and prevents expensive future retrofits Safer and healthier homes – no combustion Enables greater EV adoption Fiscal prudence – more cost effective to address at new construction Advance climate goals  Reduced fueling costs for residents By 2025 approximately 45,000 EVs in SM Co EV savings over gas car $1,200+/year Reduced capital expenses 25,000 new housing units EV Reach Code <$1.5k/unit at new construction $7k/unit for retrofit

Model Code Summary Code Element Approach Building Electrification Provides 2 tracks for developers: All-Electric or Mixed-Fuel All-Electric (preferred) is less expensive, delivers more benefit Mixed-Fuel allows natural gas but has higher efficiency requirements Details vary by building segment Electric Vehicle Readiness Provides “plug and play” access to vehicle charging Single family: Level 2 (dryer outlet power) and Level 1 (standard 110v outlet) Multi-unit dwellings: one “EV Ready” space per unit* Office: 10% Level 2, 10% Level 1, and 30% EV Capable Other Commercial: 6% Level 2 installed and 5% Level 1 installed PCE will provide funding support for affordable housing to address EV measures

Guiding Principles for Reach Codes Preserve a low cost compliance option to minimize impact on construction costs Encourage development of healthier, safer, lower emission buildings Reflect the values of our community Leaders in EV, solar and battery adoption rates nationwide TRC

Key Terms All-Electric - buildings using electricity for space and water heating systems Mixed Fuel – buildings using natural gas for space and water heating systems Compliance Margin – how much more energy efficient than code minimum can be done in a cost effective manner, typically expressed as a percentage (e.g. 5% compliance margin) Performance Pathway – exceed code by a certain compliance margin using CEC-approved modeling software (e.g. 5%) Prescriptive Pathway – exceed code by including a list of specific cost-effective measures (e.g. drain heat recovery or batteries), see appendix for examples. Climate Zone – San Mateo county is located within Climate Zone 3. Santa Clara county is mostly Climate Zone 4, with a small portion in Climate Zone 3. TRC

2019 State Code Basics (Title 24 Chapter 6)

What’s already included in the 2019 Code Residential Non-Res Performance Compliance Margin Energy Design Rating (EDR) Percentage Solar Photovoltaics (PV) Installation Sized to offset annual kWh consumption of mixed-fuel n/a Electric-ready 120V/20A for future electric water heater installation Prewiring of all homes for future electric heat water heater Solar PV sized to cover the electric loads associated with a mixed-fuel home Use of Energy Design Rating (EDR) for all residential energy models A minimum quantity, level, and readiness of EV charging infrastructure for residential, multi-family, and non-residential building types. TRC

What is EDR? In California codes have shifted from what was being called zero net energy to the Energy Design Rating, or “EDR”. EDR allows for a range of energy performance, rather than simply targeting zero, as in Zero Net Energy. The EDR measurement is the sum of an efficiency score and an overall score. The efficiency score is based on measures such as insulation, windows, and envelope efficiency. The overall score factors in things like onsite renewable energy and fuel sources. A building with a score of zero (or less) has maximized energy efficiency and most likely added on-site renewable generation such as rooftop solar. An EDR of Zero is equal to Zero Net Energy or Zero Energy. Zero or less is most easily achieved by an all- electric building design. A higher EDR score would indicate a less efficient building.

Outline Background & context Goals Where we go from here

Background & Context New Building codes are issued every three years Cities can amend the code (“reach code”) to meet local conditions New Code goes into effect January 1, 2020

(amend some sections within these two parts only) Building Codes All 11 sections must be adopted this year by Council Reach Code (amend some sections within these two parts only) Energy Part 6 CALGreen Part 11 2019 2019 TRC 2019

Wave of Local Action Across CA 50+ cities pursuing reach codes On July 16, Berkeley banned gas in new construction PG&E publicly supported the Berkeley gas ban

Outline Background & context Goals Where we go from here

Goals for the new Code Encourage Healthier, Safer buildings Increase number of low/no pollution vehicles Pathway toward CA emission goals Fiscal responsibility

Healthier, Safer Buildings Asthma “Remove or reduce indoor exposures by promoting the use of building materials, consumer products, and appliances that emit little or no air pollutants.” - Asthma and Indoor Air Quality in the Home by RAMP1 General Safety “Carbon monoxide, or ‘CO,’ is an odorless, colorless gas that can kill. CO is found in fumes resulting from burning fossil fuels.” - Fire Safety Topics by National Fire Safety Council 1 Regional Asthma Management and Prevention

Support low/no pollution vehicles Santa Clara County has the highest EV adoption rate in the state Code includes average minimum EV charging levels Conclusion: include a higher level of EV charging infrastructure already desired by our customers

Pathway toward Goals Major goals for CA Electricity – via SVCE 2050 Goal - 2050 Major goals for CA Electricity – via SVCE Natural Gas Transportation Fuels

Fiscal Responsibility If the future has less/no natural gas, any new gas service today creates a problem for tomorrow Adding pollution while goals require reductions Adding natural gas infrastructure while shrinking customer base Installing EV charging later as a retrofit cost 2x-5x more than during new construction All-electric homes cost less to build (no gas service/piping, 1 less appliance). If that savings is invested in solar (for example), all-electric homes cost same or less to operate.
