Topic:"Home Energy Assessment" in M12249

- E1 provided its 2025 forecast in its 2024 Annual Progress Report, filed on March 31, 2025, and noted that energy savings and demand savings are forecast to be lower in 2025, as compared to 2024 results. E1 provided the following observat...

AI summary E1's 2025 forecast projects lower energy and demand savings compared to 2024, citing reduced participation in programs like Instant Savings and Home Energy Assessment, program closures (Appliance Retirement, Green Heat), and the Canada Greener Homes Grant's closure. Declines are attributed to baseline changes, rebate reductions, and participant preferences for higher-incentive programs.

AI summary The Home Energy Assessment (HEA) program offers rebates for energy efficiency retrofits and equipment. It uses 'test-in/test-out' audits and blower door testing to measure performance. A 2024 marketing campaign focused on promoting heat pumps for electricity-saving homes, though the program also serves non-electric homes since 2018. The 2024 evaluation included surveys, audit reviews, energy savings calculations, and AMI data analysis.

AI summary Green Heat, part of Efficiency Nova Scotia's program, offers incentives for renewable heating systems. Installations dropped 21% in 2024 due to participants shifting to the Home Energy Assessment (HEA) and Canada Greener Homes Grant (CGH) programs for higher federal incentives. The program includes heat pumps, biomass, solar, and demand reduction measures, with on-bill financing by Nova Scotia Power.

AI summary E1 notes that updates to residential energy efficiency programs, including Affordable Multi-Family Housing and Home Energy Assessment, have reduced TRC results for 2026. The removal of Appliance Retirement and Green Heat programs, which had higher TRC results in prior plans, further contributed to this reduction. Some measures show reduced energy savings or increased costs.

AI summary The analysis evaluates energy efficiency program components under the 2026 DSM Extension, noting that Home Energy Assessment fails TRC due to lower savings and higher costs, while BNI Efficient Product Rebates has the highest TRC and PAC. Other components, like Mi'kmaw Home Energy Efficiency Project, pass TRC. TRC and PAC differences stem from cost inclusion and program design factors.

AI summary The document evaluates the effectiveness of three programs (Green Heat, Efficient Products Installation, and Home Energy Assessment) by analyzing participation rate differences between treatment and control groups. The evaluation found minimal differences (0.1% and 0.4%), but the text questions whether these small increases (33%, 25%, 50%) are considered practically important.

2026 DSM PROGRAMMING CHANGES On the residential side, E1 ended appliance retirement on January 8, 2025, as delivery costs were rising, savings were declining as units being retired were newer and more efficient already. In addition, starti...

AI summary E1 ended appliance retirement in 2025 due to rising costs and declining savings, replaced seasonal campaigns with year-round rebates, and added electrician-installed measures for 'Eco Shift' demand response. 'Green Heat' was retired due to lower participation from federal grants, while HEA introduced virtual audits and expanded eligibility. BNI programs saw small business measure expansions and commercial battery additions to demand response.

Anticipated Results E1 anticipates lower energy savings and lower demand savings in 2025 and 2026 compared to those achieved in 2023 and 2024, despite the notable increase in the budget. It attributes this to the following factors: - E1 ha...

AI summary E1 anticipates lower energy and demand savings in 2025-2026 despite increased budgets, citing expired LED rebates, exhausted Canada Greener Homes Grant funding, and lower demand response adoption. 2025 targets 128.7 GWh at $62M, while 2026 targets 116 GWh at $63.75M, with rising unit costs ($0.49/kWh in 2026 vs. $0.39/kWh in 2023). Residential and BNI energy savings contributions shift from 35%/65% to 51%/49%.

AI summary The 2026 DSM Extension Application evaluates program components based on TRC and PAC. Key findings include Home Energy Assessment failing TRC due to lower savings and higher costs, BNI Efficient Product Rebates having the highest TRC/PAC, and BNI sector showing higher TRC than residential. Differences in TRC/PAC calculations for energy efficiency vs. direct installation measures are noted.
