A proof of concept pilot was conducted at the South Service Centre owned and operated by EPCOR. Located in Edmonton, Canada, EPCOR are a utility company that manages water, wastewater, electricity and natural gas distribution systems in Alberta, British Columbia and Ontario as well as the states of Arizona, New Mexico and Texas.

The pilot was run with support from BGIS; a leading global real estate and facilities management company.
EndoTherm was installed into the service centre in August 2019.

EndoTherm pilots follow guidance from the International Protocol for the Measurement & Verification of Performance (IPMVP) Option C which considers the total natural gas consumption on site given the rarity and inconsistency of sub-metering within natural gas using equipment.

Historical Data between September 2016 and July 2019 was normalized using Heating Degree Days (HDD) data from Edmonton Municipal Airport (CXEC) at a baseload of 65°F.

The baseload (above) showed that consumption had improved in the 12 months prior to EndoTherm being installed especially during a period of Sep 2018 to December 2018. A shorter baseline is therefore preferred for the pilot comparison.

The gas consumption between August 2019 and July 2020 was compared with the pre-install baseline.

For each month, a predicted consumption was calculated by inputting the known HDD (X) value for that time period into the trendline equation from the baseline. The equation was: Y = 1.1092x + 101.04

The values in summer are not reflective of the trendline. HVAC space heating is also expected to be marginal during the summer, so summer consumption was removed. Thus consumption between October 2019 and April 2020 (7 months) is the basis of the analysis.
