90.25 Btu / GSM / Degree-Day (°C)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	64,364,116 Kilowatt-hours	219,610.36 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	686,083.98 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

905,694.34 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

713,309.28 Gross square meters

Baseline period

Baseline year	1.27 MMBtu per square meter	1.58 MMBtu per square meter

Metric used in scoring for Part 2

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

15.62

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

1) York University is working to bring back the 'Res Race to Zero' challenge, an annual competition in which residences across campus face off to determine who can minimize their energy consumption the most over the month of March. Res Race to Zero was paused due to operational constraints and the impacts of the pandemic but efforts are being made to resume this initiative. Our Sustainability Innovation fund plans to allocate approximately $40,000 to this intiative in 2023.
2) York University's Sustainability website provides the York community with a list sustainability pledges, which are suggestions for small changes that individuals can make in their everyday lives. These include Energy pledges, such as turning off unneeded lights and using efficient settings.

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

---

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

York University has undertaken a variety of energy management programs over the past 10 years, including the implementation of energy efficient lighting technologies. So far, 23,230 lights have been converted to LED.

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:

The whole concept behind co-generation at York is to increase our resource efficiency and lower operating costs. The recovered heat from the cogeneration plant has many uses. In York’s case, for every 1 kilowatt of electricity which is produced, approximately 1.6 kilowatts of heat is generated. York’s co-generation plant has two gas turbines. Each turbine turns a generator that produces around 5,000 Kilowatts of electricity at 13.8 kilovolts. The plant produces approximately 60% of Keele Campus’ electricity requirements. The remaining 40% is purchased.

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

York plans to have energy meters installed in all campus buildings by July 2023, allowing for data collection and evaluation. The real-time data about energy use on campus will be available on a public platform. This information will also assist in identifying major energy users, allowing a tactical response to reducing our need for utilities.
