|Grid-purchased electricity||15574.85 MMBtu||16641.30 MMBtu|
|Electricity from on-site renewables||0 MMBtu||0 MMBtu|
|District steam/hot water (sourced from offsite)||0 MMBtu||0 MMBtu|
|Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass)||17842.21 MMBtu||27998.10 MMBtu|
|Total||33417.06 MMBtu||44639.40 MMBtu|
Start and end dates of the performance year and baseline year (or 3-year periods):
|Start Date||End Date|
|Performance Year||Jan. 1, 2018||Dec. 31, 2018|
|Baseline Year||Jan. 1, 2008||Dec. 31, 2008|
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
Gross floor area of building space:
|Performance Year||Baseline Year|
|Gross floor area of building space||46749 Gross Square Metres||42510.80 Gross Square Metres|

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
Addressing energy consumption is an important part of Sustainable Selkirk's outreach and educational efforts. Selkirk has held annual Sweater Day events since 2017, where building temperatures are turned down and students and staff are asked to wear a sweater to show their support of energy conservation. In 2018, the Castlegar campus saved 8.2 GJ of energy during the one day. These events have been successfully and showing the campus community that small changes can have big impacts.
During the 2018/2019 heating season, Selkirk participated in The BC Cool Campus Challenge, a province-wide energy conservation initiative that challenged post-secondary institutions to reduce natural gas use and encourage their respective campus communities to take an energy conservation pledge. Colleges made temperature setbacks in their buildings where feasible, and students and staff were asked to reduce their energy use by committing to four simple actions:
• turn down the heat by 1 to 3 degrees Celsius,
• layer up and wear a sweater,
• take shorter showers, and
• wash clothes in cold water.
Selkirk College participated in the Challenge in a friendly competition against five other institutions across British Columbia and was pronounced the winner, with the most pledges collected in proportion to our campus community population. Selkirk earned bragging rights and the title of The Coolest Campus in BC.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
In addition to space temperature guidelines, Selkirk continues to optimize its Building Control Systems to continually realize low cost energy savings. Some of the strategies employed as part of our continuous improvement plan include occupancy scheduling, demand-controlled ventilation, heat recovery, and pump and fan volume controlling.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Selkirk continues to make lighting improvements institution-wide. Almost all exterior HID lighting has now been replaced with modern, energy efficient and low life-cycle cost LED technologies. Indoor areas are also continually seeing the same improvements. In addition, when improvements are made, the latest technologies are employed whenever feasible, in order to increase energy savings. These technologies include occupied space scheduling, daylight harvesting, task tuning, as well as occupancy and vacancy sensing. Two recent projects of note that are utilizing all of the above technologies are realizing 70%+ energy savings.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Geothermal heating and cooling are employed at the MIR Centre for Peace at the Castlegar campus and at the Tenth Street Student Housing building in Nelson.
The Castlegar campus student housing building also utilizes 49 solar collectors on the roof to collect solar energy and efficiently convert it to heat the domestic hot water consumed onsite.
The Castlegar campus's central heating plant incorporates a highly efficient geo-exchange system that uses the existing chilled water loop as the source, extracting heat from areas such as the kitchen, that requires year-round cooling, and then transfers the heat into the central heating loop via water source heat pumps.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
Selkirk continues to educate the staff members about the college's energy reduction goals and about alternatives to high energy consuming appliances. Staff are strongly encouraged to use communal staff kitchens rather than have small appliances in their own personal offices.
In 2018, Energy Conservation Procedures were appended to Selkirk's Environmental Sustainability Policy.
During winter 2019, the Selkirk IT department deployed new Ricoh printers at all locations. These devices are highly energy efficient and features will allow us to more effectively manage both energy and paper use.

Additional documentation to support the submission:
The gross floor area reported in this credit is for the 2018 performance year. Selkirk's floor area has increased since then, so IC 2 shows a higher figure.
