Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 4,877,278 Kilowatt-hours 16,641.27 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 0 Kilowatt-hours 0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 44,639.42 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
61,280.70 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Addressing energy consumption is an important part of Sustainable Selkirk's outreach and educational efforts. Members of our campus community are encouraged to dress for the season to avoid the need to raise building temperatures. Students in housing are educated on energy conservation practices, including turning down the heat, washing clothes in cold water, having shorter showers, and putting on a sweater.

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

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The Castlegar Campus as two solar installations that generate electricity for these buildings.

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:

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
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. We continue to create more communal lunchroom spaces for both students and staff when space becomes available.
