Custom - › Compared to 2023, Custom participation decreased in 2024. While Retrofit and Building Optimization participation levels decreased, New Construction participation significantly increased in 2024. - › Following the project reviews...
AI summary Custom program participation decreased in 2024, with Retrofit and Building Optimization participation declining while New Construction increased. The Evaluator adjusted energy and peak demand savings estimates, noting reduced free-ridership (15% for Retrofit, 28% for New Construction) and no spillover. Evaluated savings were 8% and 5% higher than E1's tracked figures.
Building Optimization (BOpt) - Technical and financial support to help organizations conduct an investigation study with the objective of improving building operational efficiency. - Technical and financial support for the implementation o...
AI summary Building Optimization (BOpt) provides technical and financial support for investigations and low-cost energy efficiency measures in eligible facilities. Eligibility requires facilities to have a building automation system, annual consumption of 350,000 kWh or more, and not have been commissioned in the past two years.
Building Optimization A total of three Building Optimization projects reported savings in 2024: two single-year projects and one project that claimed partial savings since it began in 2024 but was not completed. One of the completed projec...
AI summary Three Building Optimization projects reported 2024 savings, with energy savings per project up 53% despite fewer projects. Total savings increased by 219% and 48% for energy and peak demand, respectively, due to a partial savings claim from an uncompleted project.
2 Custom Evaluation Approach The 2024 Custom evaluation comprised a comprehensive impact evaluation for Retrofit, Building Optimization, and New Construction. For Building Optimization, given its smaller contribution to Custom savings, NTG...
AI summary The 2024 Custom evaluation assessed Retrofit, Building Optimization, and New Construction programs, focusing on energy savings, GHG reductions, and participation analysis. NTGR 2021 data was applied for Building Optimization due to 2024 project inactivity. Objectives included calculating savings, analyzing sub-sector/region participation, and reviewing logic models.
6 Building Optimization Impact Evaluation The objectives of the 2024 Building Optimization impact evaluation were to determine gross and net electrical energy and peak demand savings, annually avoided GHG emissions, as well as EUL values a...
AI summary The 2024 Building Optimization Impact Evaluation assesses energy and peak demand savings, GHG emissions reduction, and EUL values. It categorizes savings into partial, single-year, and multiyear projects, with two single-year projects claiming final savings in 2024.
6.2 Gross Savings Gross savings correspond to changes in energy consumption resulting from actions taken by Building Optimization participants regardless of why they participated. This subsection describes the review methodology used for a...
AI summary Gross savings in Building Optimization projects are calculated based on energy consumption changes, using data from participants and E1, supplemented by engineering assumptions. The Evaluator applied best measurement and verification practices for commercial and industrial energy efficiency projects.
6.2.4 Evaluated Gross Savings [Table](#page-18-0) 24 below presents the overall evaluated gross savings for Building Optimization, which were obtained by applying project-specific adjustments to energy and peak demand savings as a result o...
AI summary The section discusses the evaluation of gross savings for Building Optimization projects, including adjustments for energy and peak demand savings based on project reviews. Line loss factors from the 2014 Cost of Service Study Progress Update were used to calculate savings at the generator level for each project.
APPENDIX V Retrofit and Building Optimization Project Review Protocols
AI summary Appendix V outlines protocols for reviewing retrofit and building optimization projects, likely part of Nova Scotia's regulatory framework for energy efficiency and building standards. It focuses on evaluation criteria and processes for such initiatives.
This appendix summarizes all the recommendations made by the Evaluator as part of the Custom evaluation. Section Recommendations Executive Summary 2024 New Construction Recommendation #1: Review the demand savings script used for projects...
AI summary The appendix outlines recommendations for improving energy efficiency programs in Nova Scotia, including enhancing modelling accuracy, increasing M&V requirements, recruiting energy modellers, aligning with NECB 2020, and updating program guidelines to address barriers and improve participation.
