When I sat down with Rebecca Mitchell, a seasoned sustainability consultant with over a decade of experience in green building certifications, I anticipated a detailed and jargon-heavy discussion. However, what unfolded was a captivating and enlightening conversation that demystified the complexities of green building certification systems. Rebecca’s insights into the Green Building Certification System Review, particularly the 2024 findings, offered a comprehensive view of the ever-evolving landscape of sustainable construction.

“Green building certifications are more than just a badge of honour; they are a testament to a building’s commitment to sustainability and efficiency,” Rebecca began. Her passion for the subject was palpable, and it quickly became clear why she had been chosen to contribute to the recent GSA review.
The Energy Independence and Security Act of 2007 (EISA) mandates that the General Services Administration (GSA) evaluate green building certification systems and report their findings to the Secretary of Energy. This requirement ensures that the federal government adopts the most effective and comprehensive systems for certifying high-performance green buildings.
“The 2024 review was particularly significant,” Rebecca noted. “It involved a deep dive into six primary certification systems: BOMA Best, BREEAM, Green Globes, LEED, Living Building Challenge, and WELL. Each system has its strengths and intricacies, and our task was to analyse how well they align with federal green building performance requirements.”
Rebecca explained that the review process was thorough and collaborative, incorporating input from various stakeholders, including federal agencies, the public, and private sectors. “This inclusive approach is essential,” she said, “because it ensures that the recommendations are not only robust but also practical and adaptable to real-world applications.”
One of the key aspects of the review was assessing how each certification system encourages a comprehensive and environmentally sound approach to building certification. “We looked at several factors,” Rebecca elaborated. “Energy efficiency, water conservation, indoor environmental quality, and material use were all critical components. The goal was to identify systems that support the federal government’s sustainability objectives while also being adaptable to different agencies’ unique needs.”
As Rebecca recounted the findings, it was clear that each certification system had its merits. “BOMA Best, for instance, is excellent for existing buildings and focuses heavily on operational efficiency. BREEAM, with its long history and international recognition, offers a broad perspective on sustainability. Green Globes provides a flexible approach suitable for various building types, and LEED remains one of the most widely recognised and comprehensive systems globally.”
She continued, “The Living Building Challenge is perhaps the most ambitious, aiming for buildings to be regenerative and self-sufficient. Meanwhile, WELL focuses on enhancing human health and well-being within buildings, which is becoming increasingly important in the post-pandemic world.”
One of the most intriguing parts of our conversation was Rebecca’s discussion on the evolving nature of these certification systems. “Green building standards are not static,” she emphasised. “They evolve to incorporate new research, technologies, and best practices. The GSA’s recommendation to stay involved with these systems as they evolve is crucial. It ensures that federal buildings remain at the forefront of sustainability.”
Rebecca also highlighted the importance of stakeholder input in shaping the final recommendations. “The GSA has opened the floor for comments on their draft recommendations until August 29, 2024. This feedback loop is vital as it allows for a diverse range of perspectives and experiences to inform the final decisions.”
As our conversation drew to a close, Rebecca reflected on the broader implications of the review. “The certification systems we recommend today will shape the future of federal buildings for years to come. It’s a responsibility we take very seriously because these buildings serve as benchmarks for sustainability in the wider market. They demonstrate what’s possible and inspire others to strive for higher standards.”
Walking away from our meeting, I couldn’t help but feel a renewed sense of optimism about the future of sustainable building. The dedication and expertise of professionals like Rebecca Mitchell are driving the industry forward, ensuring that our built environment not only meets but exceeds the highest standards of environmental performance.
For those interested in diving deeper into the findings and contributing their perspectives, the GSA’s invitation for comments remains open. It’s an opportunity for all stakeholders to play a part in shaping a more sustainable future.
