A third LEED Gold certification for the 1250 René-Lévesque Boulevard building

September 22, 2025

EXP’s energy transition experts recently supported BentallGreenOak through the LEED v4.1 O+M Gold recertification process for 1250 René-Lévesque Boulevard, a landmark commercial office tower in the heart of downtown Montreal. EXP’s team developed and implemented a tailored, results-driven action plan that addressed the building’s specific needs. This strategy successfully demonstrated the building’s strong energy performance and commitment to best industry practices, earning recognition from the Canada Green Building Council (CAGBC).

LEED O+M certification recognizes excellence and ongoing improvement in building operations and maintenance. It evaluates key performance areas that all contribute to occupant well-being, such as water and energy consumption, waste management, access to active and low-emission transportation options, and indoor environmental quality, including air quality and thermal comfort.

Key factors behind the recertification:

  • Enhanced indoor environmental quality: Ongoing maintenance and operational strategies ensure high indoor air quality and optimal occupant comfort.
  • Promotion of sustainable mobility: Spaces support and encourage sustainable transportation options.
  • Responsible waste management: Strategies focus on waste reduction at the source and diversion from landfills.
  • Efficient resource use: Measures implemented to reduce water and energy consumption and greenhouse gas emissions.

“This recertification reflects BentallGreenOak’s and their tenants’ shared commitment to reducing environmental impact. It also highlights the project’s operations and maintenance excellence and strong collaboration with EXP,” said Manuelle Croft, Project Manager – Energy Transition. “We’re proud to have helped our client reach their sustainability goals through this process.”
