Total site energy consumption per unit of EUI-adjusted floor area per degree day, performance year:
7.07 Btu / GSF / Degree-Day (°F)

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 16,050,000 Kilowatt-hours 54,762.60 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 63,454.78 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
118,217.38 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
813,272.85 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period Jan. 1, 2010 Dec. 31, 2010

A brief description of when and why the energy consumption baseline was adopted:
The baseline is 2010, which followed substantial energy retro-fits and energy conservation measures at TRU. As well, 2010 was used as the baseline in the TRU 2018 STARS report submission so, in order to be consistent, it should be used for this report.

Source energy

Source-site ratio for imported electricity:
2

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.07 MMBtu per square foot 0.09 MMBtu per square foot
Baseline year 0.15 MMBtu per square foot 0.21 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
55.95

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
TRU Staff/Faculty Sustainability Ambassador Program

The Sustainability Office piloted the Sustainability Ambassadors program in the 2015/2016 school year, and then rolled out the actual program the next year. Based on the success of the program, new departments were added. The program had to be paused due to Covid-19, and restarted during the 2021-2022 school year.

The program is focused on increasing participation in, and support for, sustainability practices and behaviours. The program is coordinated through the TRU Sustainability Office, which organizes quarterly meetings and offers training and on-going support. Employees from every department are encouraged to join the program. A delegate from a campus office/department steps forward to be the Sustainability Champion and identifies challenges within their work setting. They then provide solutions for improving the sustainability of their work environment. These ambassadors are integral in changing the way people view everyday situations through a sustainability lens, and help to communicate the initiatives being promoted. Participation is during paid work time and involves 4 hours/month.

As part of the program, the Sustainability Office developed four toolkits to help ambassadors in their sustainability efforts: Energy Conservation, Zero Waste, Sustainable Printing, and Paper Saving/Go Digital. Future toolkits, such as transportation and food/dining, will also be developed. The Energy Conservation toolkit guides users in simple conservation steps such as turning out unused lights, unplugging unused appliances, and installing timers to save on electricity. The Zero Waste toolkit explains how to properly use the roughly 20 waste streams on campus in order to try and keep as much out of the landfill as possible. The last two toolkits (Sustainable Printing and Paper Saving/Go Digital) suggest ways to reduce paper use, printing as efficiently as possible, and using a variety of digital ‘tips and tricks’ to avoid using any paper.

A brief description of energy use standards and controls employed by the institution:
ANSI/ASHRAE standard 55 Thermal Environmental Conditions for Human Occupancy and WorksafeBC's Occupational Health and Safety(OHS) regulation are two main standards employed at TRU regarding building temperature. Heating and air conditioning for buildings at TRU are controlled by a Direct Digital Control (DDC) system. All DDC systems are programmed to operate according to these two standards. Control strategies are constantly reviewed and recommissioned to adopt building changes and current control technology regarding energy conservation by using time scheduling, set-points control, outdoor temperature
monitoring, and dual max RCx etc.).

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All campus areas were retro-fitted to LED lighting technology, which now includes all exterior (high shop bays, sidewalk, parking and street lights)

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A geothermal heat pump system is used to provide heating/cooling at the House of Learning building. TRU also employed solar thermal systems at three buildings (OM, CAC, CATC) to pre-heat domestic hot water.

A brief description of co-generation employed by the institution:
n/a

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Based on the recommendations from campus wide energy audit and studies via various energy conservation programs provided by local utility providers, BC Hydro and FortisBC.
