Building Optimization In 2018, six projects were completed through Building Optimization service. The 2018 evaluation included a review of three of those projects for which both a project file review and an on-site visit was conducted. Sim...
AI summary In 2018, six Building Optimization projects were completed, with three reviewed through on-site visits and project file reviews. Participant satisfaction was high, but energy savings were reduced by 39% and peak demand savings by 22% due to engineering errors. The net electrical energy savings were 1.184 GWh, avoiding 725 tonnes of CO2 eq in annual GHG emissions.
1.1 Description Custom provides large BNI participants with technical assistance, financial incentives and project financing to help reduce their electricity consumption and demand. Custom includes three different services, broken down as...
AI summary Custom offers three services—Retrofit, New Construction, and Building Optimization—to help large BNI participants reduce electricity consumption. Retrofit supports feasibility studies and improvements at facilities consuming over 350,000 kWh annually. New Construction provides incentives for energy-efficient new buildings or renovations. Building Optimization focuses on optimizing building systems for energy savings. In 2018, these services aimed to generate 25.8 GWh of energy savings and 4.5 MW of peak demand savings.
ENS started implementing recommendation 2017 Custom-R2 by developing a quality assurance (QA) procedure to ensure that key variables are consistently reviewed in the energy models and by contracting an experienced energy modeller to review...
AI summary ENS has been implementing several recommendations to improve the Building Optimization program. This includes developing a QA procedure, updating program documents, and creating requirements for service providers. These changes aim to ensure consistent reviews and clearer eligibility criteria for participants.
Building Optimization A total of six Building Optimization projects reported savings in 2018 and all of them were completed in the same year. As depicted in Figure 6 below, after undergoing a decreasing savings trend for the past three yea...
AI summary In 2018, six Building Optimization projects reported energy savings, with an increase in savings per project due to a multi-building project that grouped ten buildings. The program was temporarily halted in 2016 for restructuring and branding changes, which had a modest impact on participation.
7 BUILDING OPTIMIZATION MARKET EVALUATION As part of the Building Optimization on-site visits, three participants answered questions regarding their satisfaction with the service, any barriers they encountered, and improvement suggestions....
AI summary Participants in the Building Optimization program expressed high satisfaction with the service, citing streamlined processes and energy savings. No significant barriers were reported, and the only suggestion for improvement was accelerating the payment process.
8 BUILDING OPTIMIZATION IMPACT EVALUATION The objective of the 2018 Building Optimization impact evaluation was to establish the gross and net electrical energy and peak demand savings. Building Optimization claims three types of savings:...
AI summary The 2018 Building Optimization impact evaluation aimed to assess electrical energy and peak demand savings. The evaluation found no partial savings, six completed projects with final savings, and no final savings from multi-year projects.
8.1 Gross Savings Gross savings correspond to changes in energy consumption resulting from actions taken by Building Optimization participants regardless of why they participated.10 This section describes the review methodology used for al...
AI summary Gross savings are defined as changes in energy consumption from Building Optimization participant actions, regardless of participation reasons. The section outlines the review methodology and adjustments for Building Optimization projects.
8.1.1 Project Review Findings Three projects were included in the review sample from the six custom building optimization projects completed in 2018. Downward adjustments were made to the energy and demand savings of all three projects. Th...
AI summary Three building optimization projects reviewed in 2018 had their energy and demand savings adjusted downward due to incorrect engineering equations, not due to unimplemented measures. Adjustments led to a 39% reduction in savings for the three projects and a 30% reduction overall for Building Optimization.
8.1.2 Interactive Effects Since interactive effects vary significantly from one Building Optimization project to another, they are taken into account in the project engineering calculations used to establish initial gross savings. No other...
AI summary Interactive effects in Building Optimization projects are considered in engineering calculations for initial gross savings, but no additional adjustments were made to the gross savings of the three reviewed projects.
APPENDIX III CUSTOM: BUILDING OPTIMIZATION ON-SITE VISIT PROTOCOL This appendix describes the protocol used as part of the Building Optimization on-site visits.
AI summary This appendix outlines the protocol for conducting on-site visits as part of the Building Optimization program, ensuring standardized procedures for assessments and evaluations.
