AI summary In 2014, the Econoler team evaluated five projects supported by EBC or EMIS components of Custom Retrofit. The evaluation aimed to recommend improvements in the methodology for documenting and calculating savings, as well as ENSC's approach to supporting and verifying these projects.
Documents The Documents tab contains the most detailed information about the 2014 Custom Retrofit projects; it typically includes scoping studies, feasibility studies, the project development agreement (PDA), M&V documentation and other pr...
AI summary The 2014 Custom Retrofit tracking system is considered adequate with signs of improvement, but recommendations include adding Nova Scotia Power rate codes, explaining diversity factors, and identifying M&V adjustments in the DSMDS report to enhance evaluation accuracy and data clarity.
Other Energy Efficiency Projects The remaining 2014 Custom projects were grouped into a second category simply named "Other Energy Efficiency Projects", and it included a variety of measures, such as HVAC upgrades, motor replacements, cont...
AI summary The 'Other Energy Efficiency Projects' category includes diverse energy conservation measures, such as HVAC upgrades and motor replacements. The weighted adjustment ratio was calculated based on a detailed review of project documentation and on-site verification of equipment installation and operation parameters.
6 IMPACT EVALUATION FOR EMIS AND EBC EMIS and EBC were two Custom Retrofit components newly introduced in 2014. This limited-scope impact evaluation was conducted on the basis of a technical review of these two sub-components' project docu...
AI summary This section discusses an impact evaluation of EMIS and EBC, two Custom Retrofit components introduced in 2014. The evaluation was based on a technical review of project documentation, with the goal of recommending improvements to the methodology for documenting and calculating savings, as well as ENSC's approach to supporting and verifying these projects.
6.1 EMIS Review A newly introduced Custom Retrofit sub-component, EMIS was first undertaken in 2013 as a pilot. The main goal of EMIS is to assist industrial clients in making real-time decisions about their process using energy consumptio...
AI summary The EMIS program, introduced in 2013, helps industrial clients make real-time energy decisions using metered system data. A review found that only two of four 2014 projects were generating savings, while others were still in implementation. The program manual and supporting documentation are well-defined, providing clear guidance for participants and consultants.
Suggestions for Improvement To improve the EMIS process and the accuracy of the tracked savings, ENSC should adopt the current version of the IPMVP released by the Efficiency Valuation Organization (EVO). Many of ENSC's staff members are c...
AI summary To improve the EMIS process and the accuracy of tracked savings, ENSC should adopt the current version of the IPMVP from EVO. This would help address weaknesses such as inadequate baseline data collection and incomplete documentation of adjustments. ENSC should also review M&V plans and verify tracked savings in quarterly reports.
6.2 Existing Building Commissioning Review As mentioned previously, EBC was one of the Custom Retrofit components newly introduced in 2014. The goal of this component is to achieve energy and peak demand savings through the appropriate and...
AI summary The Existing Building Commissioning (EBC) program, introduced in 2014, focuses on achieving energy and peak demand savings through low-cost and no-cost measures. An evaluator found that EBC is cost-effective, generating approximately 850 MWh in savings, though project documentation quality varied significantly.
