14.2.1 Installation Rates Installation rates represent the proportion of products recorded in the tracking sheet that remain installed in participants' homes. No data collection aimed at updating installation rates for measures of the EPI...
AI summary Installation rates for energy efficiency measures are discussed, with data from 2021 being used due to a lack of 2023 data collection. A 100% installation rate was assumed for smart thermostats in a pilot program, while a maximum of one-third was assumed for window film kits due to self-installation complexity.
As part of the 2019 evaluation, the Evaluator conducted on-site visits (n = 28) to establish an overview of the types of lamps used in homes and verify that replaced A-type lamps were properly tracked. The on-site visit results indicated t...
AI summary The Evaluator conducted on-site visits in 2019 to assess lamp replacements and found discrepancies in tracked savings. An adjustment ratio of 96% was applied to correct these discrepancies. In 2023, EOne introduced new product categories to track more LED lamps, but no new data collection was done to update the adjustment ratio.
Table 52: 2023 EPI Participant Free-ridership Levels Average Free-ridership Level Margin of Error Low-income Participants All Products 0% N/A Non-low-income Participants LED Lighting 25% 3.6% Low-flow Showerheads 10% 3.0% Other Products 0%...
AI summary Table 52 presents the 2023 free-ridership levels for EPI participants, showing that non-low-income participants had 25% free-ridership for LED lighting and 10% for low-flow showerheads, while low-income and other product categories had 0% free-ridership. Section 14.3.2 discusses participant spillover.
For EPI, participant spillover occurs when participants purchase and install additional energy efficient products due to the influence of having participated in the program component without receiving any additional support from an EOne pr...
AI summary The document discusses participant spillover in the EPI program, where participants install additional energy-efficient products without additional support. No new data was collected in 2023, so the 2021 spillover level was used for the 2023 evaluation.
3.2.2 Interactive Effects Interactive effects occur when the implementation of energy efficiency measures has an impact on the energy consumption of other elements such as heating and cooling; this is considered in the gross savings standa...
AI summary This section discusses interactive effects in energy efficiency measures, focusing on lighting projects under the BER program. Adjustments based on the BER CIRx Screening Tool were applied, and observations from site visits were used to ensure accurate interactive effects factors were used.
D9E. The availability of a list of contractors through the Efficiency Preferred Partners 2023 2021 Sample Size 19 41 MEAN 4.9 5.0 Mean excludes responses of 'Don't know' and 'Refused'.
AI summary The document presents a comparison of survey responses from 2021 and 2023 regarding the availability of a list of contractors through the Efficiency Preferred Partners. The mean scores for both years are very similar, with 5.0 in 2021 and 4.9 in 2023, excluding responses of 'Don't know' and 'Refused'.
D16E. The availability of a list of contractors through the Efficiency Preferred Partners 2023 2021 Sample Size 20 8 MEAN 4.8 4.0 Mean excludes responses of 'Don't know' and 'Refused'
AI summary This section discusses the availability of a list of contractors through the Efficiency Preferred Partners, with data showing a mean score of 4.8 in 2023 and 4.0 in 2021, excluding responses of 'Don't know' and 'Refused'.

AI summary Table 38 presents the EPI Faucet Aerator Installation Rate, showing an 85% installation rate for regular installations with a 6.8% margin of error, and an 18% installation rate for mail-out installations, with data sourced from evaluations and a Direct Mail pilot by the IESO.
Smart power bars rebated under EPI are classified as Tier 2, while those rebated under Instant Savings are classified as Tier 1. Tier 1 smart power bars have a master outlet that switches off other outlets when the master device is turned...
AI summary The text discusses the classification and energy savings associated with Tier 1 and Tier 2 smart power bars under the Efficient Product Installation (EPI) and Instant Savings programs. It references studies and technical manuals to support the unitary savings values for these devices.
