The performance of EndoTherm has been piloted in six locations within five schools which form part of the Burnaby School District. This pilot has been funded by the FORTIS BC: Innovation Demonstration Program to validate the claims of energy conservation measures (ECMs).
Monthly data was provided by Burnaby School District for all schools dating back to September 2016. Taking guidance from the International Protocol of the Measurement and Verification of Performance (IPMVP) a regression graph was constructed using this data; normalized with Heating Degree Days from a weather station (Brentwood-Parkcrest) in the Burnaby area. Summer consumption has been removed from all schools as operational parameters are different and many schools turn off their space heating over the summer period.
The trendline was used to compare against consumption recorded after EndoTherm was installed in August 2018. A cumulative sum (CUSUM) of each month determined the success of the project over the case study period.
