A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls employed by the institution:
Annually, FMP does a systems switchover from heating to cooling taking into account two important constraints:
(1) three consecutive days of 25 degrees Celsius outside temperature, and
(2) weather projections for the next 14 days.
The weather projections are very important because if we were to start the cooling systems and subsequently have water freeze in the cooling towers and pipes, this could inflict major damage to the mechanical parts of the systems, delaying cooling for the season while systems are repaired – and we do not want to do that.
The switchover process usually starts mid May. However, we continue to monitor temperatures and weather forecasts and will respond as appropriate.
The changeover to cooling is performed on the basis of priorities established to
(1) provide comfort to students living in University Housing,
(2) maintain required temperatures to protect equipment and research in progress, and
(3) serve the greatest number of individuals and activities.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Currently, a small portion of the lighting across campus has been converted to LED. It is our mission to convert all lighting, eventually, to LED lighting. This is being done through gradual retrofits and upgrades campus-wide.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution:
Cogeneration system to be in-service Jan 1st 2018.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
As identified in the energy master plan, buildings are upgraded and retrofits are implemented on average of one building per year. Recommissioning efforts are ongoing for building on an as-needed basis
