A brief description of when and why the energy consumption baseline was adopted:

Energy consumption data are available since 2002, but the baseline used is the average of 3 fiscal years (2012-15). The reason is simply that the baseline and the performance year (2019-20) are 5 years apart, allowing us to evaluate if we are consistently improving over time.


Source-site ratio for imported electricity:
2

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0 MMBtu / GSM 0 MMBtu / GSM
Baseline year 0 MMBtu / GSM 0 MMBtu / GSM

Percentage reduction in total source energy consumption per unit of floor area from baseline:
73.82

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

During the last 3 years, HEC infrastructure management team has been educating building operators to the importance of considering operational impacts on energy consumption. By involving operation staff, ranging from site technicians to the janitor, to the importance of monitoring and improving our energy performance, HEC is ensuring that its staff shows the right example to the entire community.
In 2020, HEC Montréal participated in the Défi Energy en Immobilier (a regional competition between hundreds of commercial and institutional buildings to reduce their energy consumption), and CSC Building was recognized as the building that improved the most of its energy consumption as a result of the team effort to reduce energy consumption through controls and renovations.


A brief description of energy use standards and controls employed by the institution:

The two main buildings are operated using a BAS (building automation systems), which ensure optimal air quality is maintained while taking into consideration the energetic impact of HVAC. By monitoring and fine-tuning the BAS, we are able to reduce to the limit the use of our gas boilers (for heating and humidification) by maximizing the reclaim capacity of our chillers. CO2 monitors are also precious tools to ensure the right amount of air is used to keep the atmosphere optimal in public spaces as well as classrooms.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Gradual re-lamping are in progress; most halogen have been converted to CFL, outdoor lighting as well. The next conversion steps will concern specialized lighting, CFL and T-12. The use of LED is now the standard for all renovated spaces.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

A retro-commissioning project was completed during the last five years for the Decelles building, and such project is in the plan for the CSC buildings. A major project was completed in 2016 to replace the cooling tower at CSC building with newer, energy efficient cooling towers.
In 2021, a boiler replacement project will be launched at de Decelles building. Rather than simply replacing the existing natural gas boiler with newer one, the system design will be modified to add an electric boiler that will be used off-peak to heat the building while respecting its electric capacity. Electricity in Montréal is 100% renewal (hydro or wind), and carbon neutral, thus it is preferred over natural gas for heating equipment.
