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 was adopted by the Energy Management Committee in pursuit of the ISO 50001 Management System (standard requirement) which was implemented in 2016.

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):

When onboarding, HR provides new employees with a short list of simple, sustainable practices when working at MacEwan. One of the items outlined is a reminder to turn of computers and monitors at the end of the day. Through the peer-to-peer program Green Spaces (formerly Green Impact), participitating teams (from labs and offices) are encouraged to an energy-conscious behavior and to establish energy-saving solutions within their workspaces and teams.

In concurrence with promotions for the Earth Hour Race, the Office of Sustainability promoted the "One Hour, No Power: Campus Challenge", which is an annual competition hosted by the University of Alberta that invites Alberta post-secondary institutions to educate about saving power and collect pledges from their students, staff, and faculty to participate in Earth Hour. During the Earth Hour Race (see engagement credits) itself, several challenges aim to educate participants about alternative energy sources, (building) energy efficiency aspects and the results of an overall too high energy consumption from conventional sources.

Photocopy room tips: Until May 2018, the Office of Sustainability put up large magnetic white boards in each of the three photocopy rooms at the University Service Centre. This is where most MacEwan staff members have their offices. The photocopy room tips covered a wide spectrum of sustainable life practices, energy-efficient behaviour was one of them.

Tenant sub-metering - With the construction of new buildings, tenant space (i.e. food services) is sub-metered separately. This allows us to determine how much energy that tenant is using and work to reduce their energy consumption while maintaining their brand standards.

Visible Energy Efficiency Projects - Installation of a solar array facing 104th Ave. Due to the visibility of this location, as well as on-campus news stories, staff, faculty and students have been involved in the solar conversation with some data being used in one of the classes.


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

Building temperatures are controlled centrally through a building automation system. Temperatures are kept between 21 and 23 degrees.
Buildings have minimum, maximum, night setback temperature control standards, HVAC automation schedules, lighting automation schedules, light harvesting, occupancy sensors for rooms controlled though the various BMS automation systems.


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

Systematically retrofitting sections of the buildings to LED lighting. Started 2014 and are continuing sections every year applying ISO 500001 strategies and targets.


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

Installed small solar project at Robbins Health Learning Centre 2017 and now working towards the feasibility and implementation of large projects throughout the campus.


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

N/A


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):

Implementing through our procurement department , project requirements, RFP processes, new construction, purchasing energy efficient equipment.
MacEwan University has completed numerous retrofits, including the replacement of pool systems with energy efficient units, including heat recovery, and installation of variable frequency drives on air handlers and pumps.
