The Fonds’ head office building located in Montréal sources its energy from electricity, natural gas, fuel oil and propane. Renewable energy represented 92% of total energy consumption, an exceptional proportion.
Total energy consumption went up 4% in 2012-2013 (24,106 GJ) compared to 2011-2012 (23,177 GJ), partly due to colder temperatures during the 2012-2013 winter, which increased natural gas consumption for the following year.
As the 2011-2012 financial year was unusual in terms of low energy consumption, it is preferable to compare our results with the 2010-2011 financial year. The table above shows that natural gas and electricity consumed in 2012-2013 decreased 37% and 7%, respectively, compared to 2010-2011. This resulted in a reduction in total measured energy consumption of 9%, and 8% when changes in temperatures are taken into account (adjusted consumption).
Another way to assess the energy performance of a building is to measure its average energy intensity, calculated as kilowatt hour per square foot per year (ekWh/ft2/yr), which can also be used to compare the performance of various buildings. The graph above shows that the energy intensity of the Fonds’ head office is lower than that of buildings with the highest level of BOMA certification, which demonstrates that the Fonds’ head office building is very efficient.
- Measured energy consumption represents the amount of energy actually consumed in the head office building, i.e. energy billed by suppliers.
- Adjusted energy consumption takes into account changes in temperatures from one year to the next. It corresponds to the energy that would have been consumed if the temperature had been equal to the average temperature from 1971 to 2000, which is the benchmark used to adjust annual energy consumption. Temperature differences between years are therefore eliminated since consumption is based on the same temperature benchmark, making it possible to determine whether our energy efficiency has improved.
