AI summary This section discusses the Unitary Savings Review process, where the Evaluator validated and updated savings data based on previous evaluations, technical references, and product specifications. It outlines methodologies used for different program components, including Efficient Product Installation and Instant Savings.
ompleted, the time required to complete the work, the energy-efficient products installed, and the information provided by the installer, also received strong satisfaction ratings. EPI Energy Savings To calculate EPI’s gross energy savings...
AI summary The evaluation of EPI's energy savings found high installation rates across most product categories, except for smart power controllers, which had a low installation rate. Despite efforts to improve this, the rate remained low. Net energy savings were calculated using an NTGR, which varied by participant group.
has continued reviewing projects in 2017, as per Recommendation 2016 HEA-R3, to ensure the overall quality of the simulations and that all the data needed to model the homes is collected and recorded. 1.3 Participation History A total of 9...
AI summary In 2017, 931 participants took part in the Home Energy Assessment (HEA) program, with participation levels similar to the previous year but lower than in earlier years due to the discontinuation of provincial funding in 2015. Despite lower participation, average savings per participant increased significantly to 8.922 MWh, partly due to incentives for space-heating equipment and a higher percentage of participants installing such appliances.
t for the EPI 2017 evaluation. Figure 19 below shows the various data collection activities carried out for the evaluation. Figure 19: Methodological Model The Evaluator first reviewed the program component documentation and then held a me...
AI summary The evaluation of the Efficient Product Installation (EPI) program in 2017 involved a review of program documentation, a meeting with the program manager, and data collection activities aimed at achieving a 10% margin of error at a 90% confidence level. The methodology focused on ensuring precision in measurement, though it did not account for non-sampling errors.
oliday lights. Based on the evaluation results in the 2015 LED Holiday Light Exchange Report, ENS established the savings of each set of LED lights at 29.4 kWh in its tracking system. Revised Savings To update the unitary savings values us...
AI summary The report discusses the revised unitary savings value for LED holiday lights, changing from 29.4 kWh to 43.6 kWh, based on updated data from 2017. It also outlines assumptions about the number of sets replaced by participants and suggests validation methods for 2018 savings.

AI summary The document discusses the Effective Useful Life (EUL) values for energy efficiency measures under the Efficient Product Installation (EPI) program component, as reviewed by the Evaluator during the 2017 evaluation of the Existing Residential Program by Efficiency Nova Scotia (ENS).
33 7 0 E12 40 5 40 35 7 2 Chandelier Finally, LED nightlights and LED holiday lights are not affected by the Canadian or American legislation since they are not defined as general-service lamps (they generate less than 310 lumens). For LED...
AI summary The text discusses the exclusion of LED nightlights and holiday lights from certain energy efficiency legislation due to their lumens output. It also provides data on energy savings from EPI installations in 2017, including gross energy and peak demand savings, and explains the line loss factor used in calculations.

AI summary The text discusses measures to improve the quality of evaluation results, such as requiring final energy simulations, enhanced building commissioning, and full energy simulation reviews to ensure accurate model inputs for future calibration billing analysis.
2015 Evaluation Improve the internal review procedure for savings calculations of both BER BER-R1 Complete ENS agrees with this recommendation. ENS modified the participant Complete Mail-in and Instant Rebates. In 2015, the Evaluator appli...
AI summary In 2015, the Evaluator identified significant data entry errors and inconsistencies in the BER Mail-in and Instant Rebates programs, leading to large adjustments in savings calculations. ENS implemented new procedures to address these issues, including updated baseline wattages and ballast factors. Additional quality control steps are recommended to ensure accurate savings calculations.
Improve the application forms and the internal review procedure to ensure the accuracy of savings calculations SBES-R4 Complete ENS agrees with this recommendation and developed new participant Complete for DIY projects. The Evaluator foun...
AI summary The document highlights issues with the accuracy of savings calculations in energy efficiency programs, noting that variables used in the algorithm often do not reflect actual conditions. It recommends improving application forms and internal review procedures, as well as ensuring that SBEAs are qualified to conduct audits at industrial facilities.
