A recognized framework for sustainably improving your buildings’ performance
Sustainable building certifications assess a building’s ability to reduce its environmental impact ,while providing a healthy, high-performing, and comfortable indoor environment for its occupants. They are based on recognized frameworks that measure various aspects of the building, such as energy performance, water management, indoor air quality, materials used and operating practices.
For existing buildings, they are also a valuable tool for propertys managers’ operational optimization. They encourage more responsible resource management and the optimization of existing systems to extend the building’s lifespan, while reducing its environmental footprint. The goal is, therefore, to ensure more efficient and sustainable building operation, without necessarily resorting to major transformations.
Implementing certification for an existing building requires collaboration among owners, property managers, technical operators and occupants. Together, they must implement management practices and continuous improvement to achieve the objectives set by the chosen framework. Through this structured approach, certifications help make existing buildings more resilient, meaning better adapted to current and future environmental requirements.
Reduced environmental impact
By measuring and optimizing energy and water consumption as well as resource management practices, certifications help significantly reduce buildings’ environmental footprint and promote more responsible operating practices.
Improved comfort and health
Certification frameworks encourage improvements of indoor air quality, lighting, thermal and acoustic comfort, thereby contributing to the well-being and productivity of occupants.
Long-term savings
Thanks to more efficient systems and resources management, certified buildings can reduce their operating costs, particularly for energy, water, maintenance and upkeep.
Enhanced real estate value
Market-recognized certifications strengthen a building’s environmental credibility, improve its attractiveness to tenants, investors and insurers, while helping to increase its long-term value.
Structured support, from diagnosis to certification
The success of a sustainable building certification process relies on a structured approach aimed at evaluating building performance, implementing targeted improvements and ensuring compliance with the requirements of recognized frameworks such as LEED, BOMA BEST, BCZ, or WELL.
Choosing the framework
Each certification has specific criteria for environmental performance and operation. The initial analysis helps choose the most relevant certification based on the issues of all stakeholders.
Initial building performance diagnosis
An initial diagnosis assesses the building’s current performance against certification requirements. This step helps identify priority improvements and establish a clear action plan.
Team mobilization
Involving managers, technical teams and occupants promotes the adoption of good sustainable development practices and contributes to the success of the initiative.
Optimization of practices and systems
Improvement measures can be implemented to meet the framework’s criteria, including optimizing energy systems, managing resources and enhancing occupant comfort.
Support for the certification process
Preparing documentation and coordinating with the certifying body are key steps to ensure compliance with requirements and facilitate obtaining certification.
Performance monitoring
Regular monitoring of performance indicators helps maintain the results obtained and ensure the sustainability of the certification. Existing building certifications require regular recertification of properties, which demonstrates to all stakeholders that sustainability practices remain optimized at all times.
