Questions

Background: Electrification Study

Electrification is a general term that means designing or converting a building to use only electricity instead of gas for various end uses, including space heating/cooling, lighting, cooking, water heating, and process loads.

In Palo Alto, the largest GHG emission impact from buildings is from space heating/cooling, and water heating.

18

Background: Electrification Study

1. Palo Alto has a carbon-neutral electric utility

2. City Council directive to explore fuel-switching from natural gas to electricity to meet Sustainability and Climate Action plan

3. Development Services tasked with exploring building level electrification specifically for heat-pump technology for space heating/cooling and water heating

4. Electrification Task Force (ETF) formed to provide stakeholder input on feasibility study

19

Scope: Electrification Study

1. Explore potential mandates for use of heat-pump space heaters and heat-pump water heaters

2. Cost-effectiveness of fuel-switching in new construction and retrofit scenarios

3. Feasibility given current technology

4. Analysis of building code impacts

5. Operations & maintenance requirements

20

Results: Electrification Study

1. Overall heat-pump space heating and heat-pump water heating is not currently cost-effectiveness in most new and retrofit scenarios

2. Cost-effectiveness analysis assumptions could change in the future given sensitivity to specific variables (i.e. utilities rate structures, installation costs)

22

Next Steps: Electrification Study

1. Develop incentive programs for heat pump space heating and heat-pump water heating systems

2. Develop systems and processes to remove the barriers for project applicants to install heat pump technology.

3. Reevaluate the analysis within five years to assess if the variables have changes

System Capabilities

1. Identify households with assets ready for transition (NRT) –Furnace, water heater, Auto, Roof (solar)

2. Pre-assessment of viable options and best configurations

3. Customize value proposition to each household’s assets and consumer behavior

4. Facilitate the acquisition/implementation process & financing

5. Coordinate product/service delivery

6. Maintain/manage QA/QC

• Projected vs actual measures performance

• Contractor performance

• Ongoing user behavior

7. Evaluate grid-scale hourly dynamics-both demand and generation

Barry Hooper, Green Built Environment Senior Coordinator

Next Steps for Addressing CPUC Data Privacy Issues

Proposal/petition to CPUC (Barry Hooper)

Path for implementing data access for GHG inventories / climate actin planning

Would not require new legislation

Document will be circulated to local governments

CARB to review proposal in March 2017

Google Doc summarizing data issues (Brian Reyes)

Summarizes data issue from jurisdictions in California

San Francisco, Berkeley, Emeryville, Oakland, San Mateo County, etc.
