The performance of EndoTherm was piloted by Rochester Regional Hospital at two sites. TCC, a long-term ward and Cottages, a senior living residential care facility.

Initially the measurement and verification (M&V) plan was to compare pre-installation baseline consumption with post-installation data normalised with Heating Degree Days (HDD from Greater Rochester Regional Hospital – baseload temperature of 65°F). However, the COVID-19 outbreak (and subsequently observed increases in consumption) in March 2020 meant this methodology was revised to include three sites where EndoTherm was not installed as comparison. These included Edna Tina (Long Term Care), Island Cottages (Clinic) and DeMay (Living Centre) buildings.

For each site, a historical baseline was calculated using monthly consumption taken between June 2018 and January 2020. Some sites included sporadic estimated bills which were removed from consideration. A trendline, calculated from the historic consumption can be used to predict consumption based on each HDD value in the post-analysis period. This takes guidance from IPMVP (Option C). The ‘predicted consumption’ for each month can be compared with the actual recorded consumption to identify a change in efficiency of the system during that month. Analysis took place over a 5-month period between February 2020 – June 2020.
