| Total | 283,625.55 MMBtu | 238,393.32 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |

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 | 380,382.37 Gross square meters | 243,163 Gross square meters |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:

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):
The Energy Challenge is a student competition run by the First Year Leadership Program Sustainability Council. In the spring of each academic year Laurier's residences compete to conserve energy over the course of one week. Energy consumption is typically reduced by 5-10% during this week as a result of the competition. The competition is incented through a prize for the winning residence that lowers its energy consumption by the largest percentage. Students can track their energy usage through Laurier's Real-time Energy Dashboard.
Laurier's Real-time Energy Dashboard: The Dashboard provides real-time energy use data, including renewable energy generation, for buildings on Laurier Waterloo and Brantford campuses. Along with illustrating our campus' energy use and carbon footprint, it also provides Green Features initiatives going on around campus, energy conservation tips, sustainability links, an interactive discussion board, and a click to commit section dedicated to the Laurier community. The Dashboard is also used to track buildings in the annual Residence Energy Challenge (described above).
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Timers are used within the building automation system (BAS) to regulate temperatures on the Waterloo campus. During off hours (11:00 PM to 6:00 AM and on weekends), building set points can be modified to reduce energy consumption. The BAS system actively monitors the space to allow for override temperature settings should the need arise. These temporary set point modifications will also allow for the throttling back of exhaust/supply air fans as required.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
As part of our Laurier Energy Efficiency Program (LEEP) Phase 1 & 2, we retrofitted all older inefficient building lighting to LED type. The replacement of more than 20,000 light fixtures will be completed in 35 buildings at both Waterloo and Brantford campuses by December 2018. Exterior lighting was also completely retrofitted not only saving energy, but improving nighttime walkway and parking lot visibility and security. The lighting audit included a feasibility assessment for lighting controls and in many classroom and office locations occupancy sensing was installed. Daylight harvesting was also installed in a number of locations where large amounts of natural light were available.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Solar walls were installed in 2016/17 on two buildings (the Library and Bricker Residence) on the Waterloo campus as part of the LEEP project. They provide a means to use the energy from the sun to preheat a portion of the ventilation air used at the Library and Bricker Residence during the shoulder season and winter months. A dark coloured perforated metal cladding to the external wall of the buildings, which provides a source of renewable energy to supplement the building’s heating systems.
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):
Also included in the LEEP Phase 1 & 2 projects were significant re-commissioning efforts. These efforts were primarily focused on using existing Building Automation System (BAS) controls to reduce operational schedules as well as audits to test and verify temperature sensing equipment, air dampers, control valves, etc. RCx audits were completed in 28 buildings. In some cases controls were added to turn off HVAC equipment based on occupancy and building schedules.
In 2018, a number of rooftop and air handling units are being replaced with high efficiency models across the Brantford, Kitchener, and Waterloo campuses which will result in both natural gas and electricity savings. This work also includes building envelope improvements such roof and window replacements. This project was undertaken as part of the Greenhouse Gas Campus Retrofits Program, funded by Ontario’s Cap and Trade program.
