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

A brief description of any building temperature standards employed by the institution:

Winter 22 Deg. C occupied spaces / 18 Deg. C for unoccupied spaces; Summer 21 Deg. C occupied spaces/ 24 Deg. C for unoccupied spaces


A brief description of any light emitting diode (LED) lighting employed by the institution:

LED options are being considered to replace Metal Halide and High Pressure Sodium Lamps for possible large scale project for parking facilities. As well, LEDs will replace T8 fluorescent lamps for possible large scale project. There are trials in offices, parking garages and high ceiling areas. All new buildings are designed with LED lighting.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Occupancy sensors are installed in various zones across campus. Also, time scheduling has been implemented through the Campus Building Management System.


A brief description of any passive solar heating employed by the institution:
---

A brief description of any ground-source heat pumps employed by the institution:
---

A brief description of any cogeneration technologies employed by the institution:

The concept behind co-generation at York is to increase resource efficiency and lower operating costs. Co-generation uses a single fuel source, natural gas, to produce electricity and heat. Co-generation is more efficient, less expensive and more environmentally responsible than purchasing electricity and heat separately, because it makes use of the “waste” heat that would normally be expelled in the process. 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 approximately 5,000 Kilowatts of electricity at 13.8 kilovolts. The plant produces approximately 60% of the Keele campus’ electricity requirements


A brief description of any building recommissioning or retrofit program employed by the institution:

As per the Energy Conservation and Demand Management plan, the University is committed retrofitting and upgrading windows, HVAC, old appliances and many other systems which create excess energy consumption.


A brief description of any energy metering and management systems employed by the institution:

As per the Energy Conservation and Demand Management plan, the university is going to upgrade the Building Automation System (BAS) Demand Response (DR) for peak shaving.


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

Many HVAC systems, water chilling systems, and other appliances are being upgraded to higher energy efficiency models.


A brief description of any energy-efficient landscape design initiatives employed by the institution:
---

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
---

A brief description of other energy conservation and efficiency initiatives employed by the institution:
