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.
![Page 18: Multi-city Working Group Webinar January 24, 2017 · 2019-12-11 · Multi-city Working Group Webinar January 24, 2017 1 RICAPS technical assistance is available through the San Mateo](https://reader035.vdocuments.us/reader035/viewer/2022081702/5f7b63ccd47c7903ee2165a6/html5/thumbnails/18.jpg)
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
![Page 19: Multi-city Working Group Webinar January 24, 2017 · 2019-12-11 · Multi-city Working Group Webinar January 24, 2017 1 RICAPS technical assistance is available through the San Mateo](https://reader035.vdocuments.us/reader035/viewer/2022081702/5f7b63ccd47c7903ee2165a6/html5/thumbnails/19.jpg)
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
![Page 20: Multi-city Working Group Webinar January 24, 2017 · 2019-12-11 · Multi-city Working Group Webinar January 24, 2017 1 RICAPS technical assistance is available through the San Mateo](https://reader035.vdocuments.us/reader035/viewer/2022081702/5f7b63ccd47c7903ee2165a6/html5/thumbnails/20.jpg)
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)

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
