AI summary In 2014, Instant Savings achieved 9.360 GWh in net electricity savings and 1.479 MW in net peak demand savings. However, evaluated savings were 38% and 31% lower than tracked values, respectively. Adjustments to baseline wattage for LED lamps and changes in free-ridership levels contributed to the discrepancies.
Green Heat The evaluation of Green Heat demonstrated that in 2014, the program had a total of 235 participants and generated net energy savings of 1.472 GWh and net peak demand savings of 0.594 MW. The net energy savings calculated through...
AI summary The Green Heat program in 2014 had 235 participants and achieved net energy savings of 1.472 GWh and peak demand savings of 0.594 MW. However, these figures are lower than those in the tracking report due to factors like a lower NTGR, reduced unitary savings for geothermal heat pumps, and adjustments for heat pumps used as primary heating systems.
Residential Direct Install Residential Direct Install had a total of 13,945 participants in 2014, and achieved net energy and peak demand savings of 24.552 GWh and 5.721 MW respectively. In addition to the regular Residential Direct Instal...
AI summary The Residential Direct Install program achieved significant energy and peak demand savings in 2014, with additional savings from a CBSM Pilot. Evaluated savings were slightly lower than tracked values due to adjustments in unitary savings, installation rates, and free-ridership levels, which were offset by increased internal spillover effects.
LED Holiday Light Exchange In 2014, a total of 117 events were held for LED Holiday Light Exchange. The evaluation demonstrated net energy savings of 0.192 GWh and net peak demand savings of 0.414 MW resulting from the distribution of 6,34...
AI summary The LED Holiday Light Exchange in 2014 resulted in energy and peak demand savings, but the evaluated savings were lower than those tracked by ENSC due to revised assumptions on unitary savings and the inclusion of an interactive effect factor. These changes reduced the estimated net demand savings by 66%.
Home Energy Report Since its inception in 2013, a total of 93,119 participants have taken part in the paper-based component of Home Energy Report, and 10,669 participants have taken part in the web-based component. In terms of net energy s...
AI summary The Home Energy Report program, since 2013, has engaged over 100,000 participants through paper-based and web-based components, achieving significant energy savings in 2014. The paper-based component achieved 25.336 GWh of net energy savings, while the web-based component achieved 0.100 GWh. Net savings were calculated using a control group comparison for the paper-based component and self-declared data for the web-based component.
Business Energy Rebates The impact evaluation has shown that in 2014, the number of participants in BER Mail-in increased slightly compared to previous years (198 regular participants and 122 promotional rebate participants), while the sav...
AI summary The evaluation of Business Energy Rebates (BER) in 2014 showed that mail-in rebates generated 11.073 GWh of net energy savings, while instant rebates generated 13.537 GWh, a decrease from the previous year due to lower LED downlight sales. Variations between evaluated and tracked savings were influenced by adjustments in calculation methods and changes in product sales.
Custom Retrofit In 2014, the Custom Retrofit component had a total of 100 projects implemented, which was lower than the previous years. Custom Retrofit generated net energy savings of 20.292 GWh and net peak demand savings of 1.599 MW in...
AI summary In 2014, the Custom Retrofit program had 100 projects, achieving 20.292 GWh in net energy savings and 1.599 MW in peak demand savings. EBC and EMIS contributed additional energy savings but no peak demand savings. Evaluated savings were lower than tracked savings due to changes in NTGR and adjustments to gross savings.
Custom New Construction This program component saw a total of 13 projects implemented in 2014, which resulted in net energy savings of 6.656 GWh and 2.517 MW in net peak demand savings at the generator. The gross energy and peak demand sav...
AI summary The Custom New Construction program had 13 projects in 2014, achieving 6.656 GWh in energy savings and 2.517 MW in peak demand savings. The Econoler team found discrepancies between their evaluation and ENSC's tracked savings, mainly due to adjustments for a LEED project and the inclusion of a diversity factor in ENSC's calculations.
Business Energy Solutions For 2014, Business Energy Solutions had a total of 761 participants. In addition, 51 participants implemented Rental Properties and Condos Service Common Area measures in 105 separate buildings, and 42 participant...
AI summary In 2014, Business Energy Solutions had 854 participants, achieving net energy savings of 13.175 GWh and peak demand savings of 2.570 MW. Savings were evaluated for lighting, non-lighting, LED Blitz pilot, and Rental Properties and Condos Service common space measures. Differences between tracked and evaluated results were due to adjustments in parameters such as NTGR, ballast factor, heat pump operating hours, and LED lamp unitary savings.
Codes and Standards For Codes and Standards, the evaluation has estimated the impact in terms of energy and peak demand savings to be achieved by introducing new regulations into the Nova Scotia market for the products targeted by federal...
AI summary The evaluation of Codes and Standards in Nova Scotia estimates energy and peak demand savings from new regulations, including increased stringency on minimum energy performance standards (MEPS). The Evaluator modified its methodology by interviewing Natural Resources Canada and industry associations to obtain reliable market size data, leading to an estimated savings of 31.433 GWh and 5.164 MW.
2.4 Evolution of Program Component Performance In 2014, ENSC's program component portfolio achieved a total of 151.888 GWh in net energy savings and 27.077 MW in net peak demand savings at the generator. These figures represent a slight de...
