A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

In 2013, the University of Guelph launched the Green Gryphon Initiative. The Green Gryphon Initiative continues today, and includes energy retrofit projects in addition to behavioral change initiatives.


A brief description of energy use standards and controls employed by the institution:
---

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

The University employees are a variety of energy-efficient lighting strategies including day light harvesting photo sensors, automated controls and occupancy sensors.


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

The City of Guelph depends on an aquifer to supply the community with potable drinking water. As a result, geothermal systems are restricted in 97% of the City. The University is located within a Wellhead Protection Zone and as such, cannot construct closed or open loop geothermal systems. However, Air Source Heat Pumps are used in buildings that are not connected to the District Energy System.


A brief description of co-generation employed by the institution:

Co-generation is currently not employed by the institution.


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

The Green Gryphon Initiative is a $26.2 million energy conservation retrofit program. This include stack heat recovery technology, LED lighting retrofits, and a Thermal Energy Storage System.
