Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 85,086 MMBtu 85,086 MMBtu
Electricity from on-site renewables 3,506 MMBtu 3,506 MMBtu
District steam/hot water (sourced from offsite) 21,898 MMBtu 21,898 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 1,026 MMBtu 1,026 MMBtu
Total 111,516 MMBtu 111,516 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, 2016 April 30, 2017

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):

The baseline year is the same year for all the credits. We selected the fiscal year for which there was the most data available and which was the most reliable.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2,441,481 Gross Square Feet 2,441,481 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.05 MMBtu / GSF 0.05 MMBtu / GSF
Source energy 0.08 MMBtu / GSF 0.08 MMBtu / GSF

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 3,931 Degree-Days (°F)
Cooling degree days 497 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 173,977 Square Feet
Healthcare space 76 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,812,719 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
8.95 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:

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):

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

The use of motion detectors connected to the building control system is a guideline in new buildings and redevelopment projects. Control sequences reduce heating setpoints and raise air conditioning setpoints during unoccupied periods, so as to not heat or cool down unoccupied rooms. Motion detectors also serve to change control sequences as well as the closing of lights and projectors in classrooms during unoccupied periods. The use of variable speed drives is used to reduce the speed of fans and pumps to reduce flows when the demand for cooled water and air resources is decreasing due to vacancy.

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

LED technology is mandatory in new construction and redevelopment projects. This practice is also applied when we have to change lighting fixtures and lighting that is constantly on, for example exit lighting, emergency lighting in general, traffic signs, etc.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The objective of ÉTS is to optimize the use of resources including energy, this is why recovery systems have been installed in most ventilation systems and mixed water loops. This type of system allows the energy consumed to be reused seasonally. Geothermal wells have been installed to store energy in student residences. A CO2 heat pump is used to take the energy stored in geothermal wells to heat domestic water used by residents and for ventilation systems.

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):

ÉTS always advocates innovation. The Real Estate Asset Services advocates innovation and new energy strategies by using new technologies in all areas of the building, and by replacing all energy-intensive appliances, at the end of their useful or obsolete life, with efficient and less energy-intensive ones. To detect the obsolescence or inefficiency of a device, rigorous analysis are carried out to calculate performance coefficients or performance indicators.

Additional documentation to support the submission:

Geothermal wells are installed in Residence 3, and these wells serve Residences 3 and 4. These two buildings have a consumption rate of 0.33 GJ/m², a very low rate for buildings of this type, thanks to the use of geothermal energy and energy recovery in the systems.
