A brief description of when and why the energy consumption baseline was adopted:
2010 was the first year for which Douglas has consistent and reliable energy data, and is the baseline the College has adopted for all of our energy reporting.

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 energy use standards and controls employed by the institution:
Douglas College has implemented daylight and motion sensors in many areas of the campus, in order to reduce energy usage associated with lighting. This includes in several recent Parkade lighting upgrades, where by the LED fixtures that were installed use less than half the power of the previous fixtures, and the lights dim to 20% after 20 minutes of inactivity, and then shut off after 20 minutes later if no motion is detected.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Douglas has made a substantial push to replacing lighting with LED lighting, including:
- Installation of LED lights c/w motion detectors in all stairwells. The new lights use 50% of the power and are set to dim to 20% when not in use.
- Installation of 60 LED lights in the Bookstore. The new lights use 50% of the power and are now tied into our lighting control
system.
- Retrofitting all hallway fixtures to LED and replaced 1,000 32-watt fluorescent tubes with 9.5-watt LED tubes. New drivers were installed and all the lenses were cleaned, eliminating the need for maintenance for another 40,000 hours.
At the Coquitlam campus:
- Installation of LED lighting in the parkade that uses less than half the power of previous lighting. Lights over the parking spots dim to 30% if no motion is detected then shut off after 20 minutes.
- Installation of LED lighting in most stairwells c/w motion detectors for dimming to 20%.
- Replacement of 40 2-tube fluorescent lights with 20-watt flat panel LED fixtures c/w motion detectors, which use less than half the power and have a life expectancy of four times longer.
- Retrofit of all high boiler room lights to LED.
- Retrofit of all exterior metal halide or HPS pole fixtures to LED, including in the surface parking lot. The new LED bulbs use one third
of the power compared to the existing bulbs and last at least twice as long, reducing servicing costs.
