Project Update

The project remains on track with key planning and coordination efforts across the Technical Advisory Committee (TAC), recruitment, and instrumentation activities. The TAC was finalized and convened, with member feedback integrated into critical deliverables such as the Performance Metrics Summary and the Knowledge Transfer Plan, both submitted in November 2025. Concurrently, the team completed a comprehensive Site Recruitment Plan and developed participant outreach materials to support the enrollment of 100 single-family homes, while coordinating with Community Action Ventura to assume an active recruitment role. Additionally, the Metrics, Instrumentation, and Monitoring Plan was refined based on TAC input, equipment testing and procurement advanced, and preparations are underway for sensor installation and contractor training slated for early 2026.

The Issue

Many households lack clear, accessible information about the full range of benefits associated with home electrification, particularly the non-energy impacts such as improved indoor air quality, comfort, and safety. This information gap contributes to hesitation and resistance, especially when residents are concerned that switching from natural gas to electric appliances could increase their monthly utility bills. The risk of higher costs is more pronounced for low-income households living in homes with poor insulation or high heating and cooling demands. As a result, existing incentive programs that focus primarily on equipment replacement may unintentionally create financial strain if they do not address overall home efficiency. A more comprehensive understanding of both the benefits and cost implications of electrification is needed to support informed decision-making and equitable program design.

Project Innovation

This project advances innovation by integrating real-world home electrification demonstrations with indoor air quality monitoring to better quantify non-energy benefits such as health, comfort, and safety. Rather than focusing solely on equipment replacement, the project uses a data-driven pre-screening process to identify homes where electrification can deliver net bill savings based on historical usage and existing equipment performance. The approach further innovates by pairing electrification upgrades with targeted energy efficiency improvements to optimize both cost outcomes and emissions reductions. Indoor air quality data will be analyzed to estimate potential health benefits, expanding the evidence base for residential electrification.

Project Goals

Create standard metrics to measure non-energy impacts (air quality, comfort, safety) of home energy upgrades.

Measure improvements on a diverse, statistically significant home sample in Ventura, SLO, and Santa Barbara Counties.

Analyze equity impacts by housing, income, and proximity to OTC plants to determine measure-specific outcomes.

Determine best practices for maximizing bill savings and non-energy benefits for disadvantaged and low-income households

Project Benefits

This project delivers multiple direct benefits to ratepayers by reducing household energy costs while improving health, comfort, and safety. Participants are expected to see lower utility expenses through decreased or eliminated natural gas use and the installation of high-efficiency electric appliances. Home electrification is also anticipated to improve indoor air quality, which is closely linked to better health and overall household comfort. Safety benefits include reduced risks associated with gas leaks, and the use of flammable fuels in the home. Additional protections will result from professional installation practices and adherence to high-quality retrofit standards. By documenting these non-energy benefits, the project strengthens the case for cost-effective electrification programs that provide long-term value for homeowners.

Affordability

This project lowers household utility costs by testing high-efficiency electric retrofits, including consolidated and staged approaches to minimize expenses, especially for low-income residents. By evaluating appliance performance and building upgrades, the research identifies cost-effective electrification pathways, avoiding bill increases and helping reduce long-term energy costs for California ratepayers through improved deployment strategies.

Environmental Sustainability

By replacing natural gas appliances with electric technologies and measuring indoor environmental conditions before and after retrofits, the project will generate data on potential reductions in combustion-related pollutants and improvements in indoor air quality. Results will help inform programs and policies that protect public health and improve indoor environmental quality, particularly for low-income and disadvantaged communities.

Safety

This project evaluates the safety benefits of replacing natural gas appliances with electric technology in existing homes, aimed at reducing combustion hazards, gas leaks, and fire risks. It will identify best practices for safe installation and integrated retrofits, providing guidance to homeowners, contractors, and program administrators to support safe, effective building electrification.
