York Catholic District School Board is the most energy efficient school board in Ontario, from among the 45 school boards analyzed for our project with Toronto and Region Conservation Authority. Take a look at their estimated savings potential and other Top Ten board profiles at Sustainable Schools. These are the school boards with energy use intensity closest to the target (based on good performance standards from the Sustainable Schools database), that is, with the lowest energy savings potential.
Our estimates show that collectively, the 45 boards could reduce their total energy use by 30%. This includes 15% in electricity savings potential, amounting to 197,485 MWh per year, and natural gas savings potential of 40.6%, or 103.7 million m3 annually. Realization of this potential could generate over $41 million per year in utility cost savings, and would lower provincial greenhouse gas emissions by more than 40 thousand tonnes of CO2e per year.
Here is our white paper detailing the methodology behind this analysis.
