Building Reach Codes Advancing safer healthier and more

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

Purpose • Support Cities in meeting climate goals o Encourage safer, healthier all-electric buildings within the building code o Install EV charging during building construction commensurate with local needs 2

Guiding Principles 1. Provide cost-effective pathways for both All-Electric and Dual-Fuel (electric + gas) construction 2. Establish the highest possible requirements that are still costeffective for Dual-Fuel construction. 3. Recommendations must comply within CEC energy code guidelines 3

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). 4

I. Reach Code Introductory Slides • What are Reach Codes • Benefits • Model Code Summary • Partners for project • Timeline 5

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: 1. Building electrification – reduced use of natural gas (methane) and associated emissions 2. Electric vehicle (EV) charging – increased EV readiness 6

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 7

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 • • • Provides “plug and play” access to vehicle charging Single family: Level 2 (dryer outlet power) and Level 1 (standard 110 v 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 Electric Vehicle Readiness PCE will provide funding support for affordable housing to address EV measures 8

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. 18

2019 State Code Basics (Title 24 Chapter 6)

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

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 allelectric building design. A higher EDR score would indicate a less efficient building. 27

APPENDIX 64

Outline 1. Background & context 2. Goals 3. Where we go from here 65

Background & Context 1. New Building codes are issued every three years 2. Cities can amend the code (“reach code”) to meet local conditions 3. New Code goes into effect January 1, 2020 66

Building Codes Reach Code (amend some sections within these two parts only) Energy CALGreen Part 6 Part 11 All 11 sections must be adopted this year by Council 2019 67

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 68

Outline 1. Background & context 2. Goals 3. Where we go from here 69

Goals for the new Code 1. 2. 3. 4. Encourage Healthier, Safer buildings Increase number of low/no pollution vehicles Pathway toward CA emission goals Fiscal responsibility 70

Healthier, Safer Buildings 1. 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 RAMP 1 2. 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 71 1 Regional Asthma Management and Prevention

Support low/no pollution vehicles 1. Santa Clara County has the highest EV adoption rate in the state 2. Code includes average minimum EV charging levels Conclusion: include a higher level of EV charging infrastructure already desired by our customers 72

Pathway toward Goals 1. Major goals for CA 1. Electricity – via SVCE 2. Natural Gas 3. Transportation Fuels 2050 Goal - 2050 73

Fiscal Responsibility 1. 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 2. Installing EV charging later as a retrofit cost 2 x-5 x more than during new construction 3. 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. 74
