A brief description of when and why the energy consumption baseline was adopted:
Historically this number has been used for our STARS reporting. It is also the baseline of the Copenhagen Accord and we have been measuring our progress again that since our office opened in 2006.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0 MMBtu per square meter | 0 MMBtu per square meter |
| Baseline year | 0 MMBtu per square meter | 0 MMBtu per square meter |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Most of the interventions performed by the University are hidden and do not require the active participation of most building users (energy retrofits of HVAC equipment). However, there are a few programs that the University capitalizes on to reduce energy consumption during select times.
-Demand Response Events - The University sends messages to all staff ahead of a Demand Response event to warn them about any disturbances and to encourage them to help out by not activating energy intensive equipment.
- Holidays and vacations - The University send messages to staff ahead of holidays encouraging them to power down to save on energy.
- Reports - The University regularly reports on its energy performance to staff and students through the website, meeting presentations, and the website.
A brief description of energy use standards and controls employed by the institution:
Each building is monitored for all its utilities. Building systems are relayed to a central monitoring system which operates in conjunction with the campus class schedule, temperature set points, and CO2 monitoring. The information is used to make adjustments for the appropriate occupancy depending on heating or cooling season.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The University has been opportunistically added LEDs for appropriate applications on campus. Currently, the university has invested in a strategy to do a bulk switch out of fluorescent T8 and T5 bulbs for LED tubes. The complete campus retrofit should be completed by the end of 2017.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The University of Ottawa does not have a comprehensive strategy to utilize passive solar heating or geothermal systems. Decisions are made on a case by case basis. The University does use trees, green roofs, and other landscaping elements to reduce cooling and heating requirements, but these too are not part of a formal strategy.
A brief description of co-generation employed by the institution:
The university no longer uses a combined heat and power system on campus.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The Univerisity has a program in place to re-engineer inefficient systems and replace energy-consuming equipment, formally names the EcoProsperity program. The program has been in place for almost a decade and targets at least one major project a year.
The University also has a green procurement policy which encourages the purchase of energy efficient equipment.
