Isotherm Engineering undertook an extensive retro-commissioning project for Toronto Metropolitan University (formerly Ryerson University), targeting three key buildings as part of the Greenhouse Gas Campus Retrofits Program (GGCRP). The project encompassed the Victoria Building, the Engineering Building, and the Mattamy Athletic Centre (MAC), focusing on mechanical systems, building automation systems (BAS), lighting, and other energy-related equipment to achieve significant emission reduction targets. The initiative was structured into four phases: feasibility study, preparation of tender and pricing documents, implementation of retrofits, and close-out & verification. Isotherm’s design and engineering teams developed all necessary engineering, design, and tender documents. At the same time, the implementation phase was carried out by contractors procured through Ryerson’s procurement department, all under the guidance and supervision of Isotherm’s commissioning teams.
The project’s outcomes were meticulously documented in the Master List of Findings (MLOF), which categorized findings into deficiencies, operation & maintenance issues, and energy conservation measures (ECMs). These measures were quantified in terms of estimated annual electric and natural gas savings and total energy savings in ekWh and as a percentage of baseline energy use for each building. Notably, the project exceeded its emission reduction targets, with the Victoria Building implementing 8 ECMs and achieving 10% energy savings, the Engineering Building implementing 19 ECMs for 9% savings, and the MAC implementing 16 ECMs, resulting in a substantial 21% energy savings. These achievements underscored Isotherm’s capacity to effectively manage and execute complex commissioning projects that significantly enhance energy efficiency and sustainability in an academic setting.
