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:

Timers are used within the building automation system (BAS) to regulate temperatures on the Waterloo campus. During off hours (11:00 PM to 6:00 AM and on weekends), building set points can be modified to reduce energy consumption. The BAS system actively monitors the space to allow for override temperature settings should the need arise. These temporary set point modifications will also allow for the throttling back of exhaust/supply air fans as required.

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

Applications for LED lighting include exterior lighting (wallpack replacements) and some indoor (meeting room/office) spaces. There are plans in place to re-evaluate the gymnasium spaces in Athletic Complex and Stadium buildings within the next few years.

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

Laurier's Brantford campus is equipped with comprehensive lighting control systems (Lutron). Passive Infrared and ultrasonic sensors are currently in use for these applications.

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:

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

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

Laurier is equipped with utility sub-meters for electricity, natural gas, and water which are installed in all buildings on the Waterloo, Kitchener and Brantford campuses. Laurier's Energy dashboard virtually displays real-time data of energy consumption for every building and tracks usage patterns and building performance. It centralizes all information into one central location- the building dashboard webpage.

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

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:
