Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 69,700 MMBtu | 77,501 MMBtu |
| Electricity from on-site renewables | 0 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 19,350 MMBtu | 30,045 MMBtu |
| Total | 89,050 MMBtu | 107,546 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | May 1, 2016 | April 30, 2017 |
| Baseline Year | May 1, 2011 | April 30, 2012 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
Energy consumption data are available since 2002, but the baseline used is the fiscal year 2011-12. The reason is simply that the baseline and the performance year (2016-17) are 5 years apart. We use the 5 years timeframe to evaluate building performance improvement and set reduction targets in other evaluation process (BOMA BEST energy reduction target).
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 106,315 Gross square meters | 104,215 Gross square meters |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.08 MMBtu per square meter | 0.10 MMBtu per square meter |
| Source energy | 0.14 MMBtu per square meter | 0.17 MMBtu per square meter |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 3,874 Degree-Days (°C) |
| Cooling degree days | 397 Degree-Days (°C) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 0 Square meters |
| Healthcare space | 0 Square meters |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
During the last 5 years, HEC infrastructure management team have been educating building operator to the importance of considering operational impacts on energy consumption. By involving operation staff, ranging from site technicians to janitor, to the importance of monitoring and improving our energy performance, HEC is insuring that its staff shows the right example to the entire community.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The two main building are operated using a BAS (building automation system), 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 classroom. HVAC system are in function from 6 am in the morning, before .
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 construction project.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
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.
