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.
| kWh | MMBtu | |
| Imported electricity | 60,395,206.93 Kilowatt-hours | 206,068.45 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 | 52,541 MMBtu |
| Imported steam, hot water, and/or chilled water | 138,270 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
An energy team was formally established in 2014, and as such this is when TMU (formerly Ryerson) started to monitor its energy footprint and progress.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The TMU website promotes the individual shift to energy reduction on our website by sharing energy reduction lifestyle tips on the Simple Sustainability Tips tab. The Sustainability Office Team conducts guest lectures for sustainability-related courses every term, where the Energy Engineer shares our initiatives to improve energy efficiency on campus. TMU hosts campus-wide Earth Day and Earth Hour events every year including running a social media campaign sharing tips on energy reduction and engaging students, faculty and staff to participate in a campus-wide clean-up. Each year, new students are engaged by the Sustainability Team during orientation to learn how they can pitch in to help TMU reduce energy consumption and carbon emissions. Other events related to energy and carbon reduction include Healthy Commute Week where students are encouraged to use sustainable modes of transportation, and Waste Reduction Week. Other seasonal campaigns include 12 days of Sustainable Christmas. In addition to the events and initiatives stated above, TMU has created an inclusive committee to create TMU's Sustainability Action Plan, for which a key priority is energy management.
A brief description of energy use standards and controls employed by the institution:
TMU has published a Sustainable Building Guidelines document in 2021 that priorities to: Significantly reduce energy use and GHG emissions from the construction and operation of its facilities to achieve Ryerson’s goal of being carbon neutral by 2050. ● Reduce stormwater runoff and potable water consumption while improving the quality of stormwater draining to local waterbodies. ● Use sustainable materials, minimize construction and operational waste and divert it from going to landfill sites. ● Protect and enhance ecological functions, integrate landscapes and decrease building-related bird collisions and mortalities. They identify a minimum level of design and process requirements and recommendations for all new construction, renovation projects, and other projects (as applicable) while providing enough flexibility for individual project teams to meet project goals. All new buildings must receive LEED Silver certification at a minimum with a specific focus on energy efficiency. Sub-meters were installed in all buildings across TMU's campus in order to more accurately measure the energy and water consumption at the building level. This information has helped to enable effective decision-making when it comes to developing energy conservation initiatives and targets, as well as identifying unusual energy consumption of individual buildings more quickly. Occupancy sensors have also been installed in approximately 60% of buildings on campus.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Energy efficient lighting strategies: Multiple LED retrofit projects have been conducted to date. Projects continue to expand and roll out to additional buildings
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Given the average age of the majority of buildings on the TMU campus is around 25 years, it can be expected that the operational use and performance of a building from an energy standpoint diminishes over time, leading to reduced energy efficiency which can impact building occupants. Over 5 buildings were retro-commissioned since 2019. Applications are underway to get incentives to retro-commission an additional 2 buildings The process of retro-commissioning existing buildings is a multistage process, involving: - In-depth analysis of a building’s actual energy use and performance - Making adjustments to the building’s automation control system - If needed, implementing equipment upgrades These investments and upgrades improve building energy performance, increase energy efficiency and improve standards for building occupants for years to come. In 2020 onwards, the department will complete the retro-commissioning of the Student Learning Centre (SLC) and the central chiller plant which is used to cool 14 buildings on campus. All new construction and renovation projects are subject to review from the Sustainability Team, which ensures that the design makes use of energy efficient appliances whenever such options are available.

Data source(s) and notes about the submission:
Additionally, all new buildings moving forward have to be designed such that Total Cost of Ownership, including maintenance and energy costs, are taken into account.
