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:

Building temperatures are controlled centrally through a building automation system. Temperatures are kept between 21 and 23 degrees.


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

LED's are used in exterior signage, exit lights, track lighting and elevators.


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

In the Robbins Health Learning Centre, occupancy sensors shut off lights and reduce air flow in offices, classrooms and labs when these areas are not in use. At City Centre Campus, occupancy sensors in classrooms and labs shut off lights when the areas are not in use.


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

N/A


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

N/A


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

N/A


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

MacEwan University has completed numerous retrofits, including energy efficient lighting retrofits at all sites, replacement of pool systems with energy efficient units, including heat recovery, and installation of variable frequency drives on air handlers and pumps.


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

All key building systems (lighting, HVAC) are monitored through a Delta Controls building management system. Energy consumption can also be monitored through this system on a building-by-building basis.


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

N/A


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

A new centrally-controlled irrigation system, complete with weather station and rain sensors was installed. Naturalized landscape design was used in the development of the landscaped areas along 109 street and in front of Building 5.


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

The majority of vending machines have been upgraded. Of the approximately 70 cold beverage vending machines across the university's campuses, over 90% are HFC free and run on 9 to 12 amps. This represents a 20% reduction in energy consumption.
