1 Darren Hanway Energy Efficiency Program Operations Manager
Zero Net Energy: The Future of Energy & Development Darren Hanway Energy Efficiency Program Operations Manager

2 ZNE GOALS California is leading the way in 2020 2025 2030
All residential new construction Retrofit 50% of existing state-owned buildings All commercial new construction Retrofit 50% of existing commercial buildings Source: California Energy Commission, 2013 Integrated Energy Policy Report 2

3 PERFORMANCE How to achieve ZNE 3 Highly energy-efficient technologies
Optimized building operations Renewable generation Integrated design 3

4 Natural Gas and ZNE 4

5 PREFERRED CHOICE Natural gas is the 95% 95% 91% 92% 83% 82% Cooking
Space heating Heating water Drying clothes Fireplaces Outlets for grill or patio heater Sources: Vision 2014 Study, conducted by Meyers Research for Building Industry Association and SoCal Gas 5

6 ABC Green Home 3.0 The residential ZNE pathway: BALANCED EE MEASURES
2017 ZNE DEMONSTRATION PROJECT BALANCED approach to ZNE using Natural Gas appliances minimizes solar PV to 3.7 kW system EE MEASURES Condensing Tankless Water Heating, Condensing Zoned HVAC, 2 PSI

7 PLAYA VISTA A vision of what’s possible: 75 kW 62 kW
LEED PLATINUM NEAR ZNE PROJECT Natural and passive ventilation 75 kW Combined Heat & Power (CHP) system supplements pool heating 62 kW Solar PV System 7

8 SoCalGas Energy Efficiency Programs
Residential California Advance Home Program Whole House Retrofit Program Home Audits Appliance Rebates No-Cost Direct Install Nonresidential Savings By Design Energy Advisor Calculated Energy Efficiency Incentives Deemed Equipment Rebates Public UC/CSU Partnership Community College Partnership Prop 39 Pilot CA State Partnership Program

9 RENEWABLE Natural gas REMOVE GHGs WHAT’S POSSIBLE
POWER 2-3 million homes WHAT’S POSSIBLE REPLACE 75% of all diesel used by CA vehicles When used for transportation, Biogas from food and green waste can actually REMOVE GHGs from the atmosphere Convert waste from dairies, farms and landfills into biogas using anaerobic digestion extract the methane put in the pipeline for future use SOURCE: Bioenergy Association of California, CARB May 2014 Look-Up Table30

10 POWER-TO-GAS Long-Term Energy Storage
carbon captured from factories and plants excess renewable energy water electrolysis which splits the molecule hydrogen & carbon combine through methanation methane can be stored in the pipeline for future use hydrogen can also be stored directly in the pipeline
