A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Fume hood operation awareness program in labs.
A recommissioning program is underway for twenty-six campus buildings to update heating, ventilation, and air conditioning equipment and control systems.
A brief description of energy use standards and controls employed by the institution:
The university follows its own Energy and Water Conservation Policy as seen here:
https://policies.usask.ca/policies/health-safety-and-environment/energy-and-water-conservation.php
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The majority of university lights have been retrofitted with LED bulbs/ballasts. Those remaining are considered part of our ongoing renovation and recommissioning efforts.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Several of our buildings on campus feature passive solar water heating.
A brief description of co-generation employed by the institution:
No co-generation is currently used by the university, though potential for its use is part of an in-progress decarbonization study.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
A recommissioning program is underway for twenty-six campus buildings to update heating, ventilation, and air conditioning equipment and control systems.
