Activities funded
- Conduct an existing-building commissioning (recommissioning) investigation to identify energy-saving opportunities and develop a commissioning plan.
- Implement operational and maintenance improvements identified through commissioning (e.g., scheduling and set point optimization, occupant behaviour measures, air and water balancing).
- Carry out minor equipment repairs or replacements required to support the commissioning improvements.
- Complete a one-year persistence phase to monitor performance and maintain the improvements with support/training from a commissioning provider.
Eligibility
Who is eligible?
- Owners, operators, or managers of commercial buildings
- Owners, operators, or managers of institutional buildings
- Commissioning providers in Ontario (to sign up as providers under the program)
Who is not eligible
- Industrial and manufacturing facilities seeking incentives for energy used by industrial/manufacturing processes (this energy use is excluded from the program’s consumption threshold).
- Organizations that have undertaken a building commissioning exercise within the last two years.
- Organizations participating in a building accreditation system that requires EBCx as a pre-requisite.
- Organizations that do not own, operate, or manage a commercial or institutional building (i.e., do not have a qualifying building type for this program).
- Organizations with facilities not connected to (or behind the meter of) an electricity customer connected to the IESO-controlled grid or a distribution system.
Eligible expenses
- Fees paid to an accredited commissioning provider to investigate the facility, prepare the investigation report, and draft the commissioning plan (up to 75% of these investigation costs).
- Costs to implement energy-efficiency operational and maintenance improvements identified in the commissioning plan (covered through pay-for-performance incentives based on verified electricity savings).
- Costs for commissioning-provider training to maintain and monitor systems for one year (covered through pay-for-performance incentives based on persisting, verified electricity savings).
Eligible geographic areas
- Ontario (commercial and institutional buildings connected to, or behind the meter of, an electricity customer connected to the IESO-controlled grid or a distribution system).
Additional information
- Incentives are tied to three phases (Investigation, Implementation, Persistence) and are only available to participants who complete each phase.
- Building commissioning is performed by an accredited/authorized commissioning provider who identifies energy conservation measures and supports implementation.
- The program includes training to help participants maintain and monitor building systems and integrate ongoing commissioning into standard management practices.
- Energy savings are calculated and verified after a 12-month period for the Persistence phase.
