In the bustling world of construction, energy rating systems are the silent orchestrators driving the shift towards sustainable building practices. To delve deeper into this critical aspect of the industry, I had the pleasure of interviewing Lisa Thomson, a seasoned sustainability consultant at GreenBuild Solutions. Lisa shared her insights on two of the most influential energy rating systems: BREEAM and LEED. Our conversation shed light on their impact, differences, and the role they play in fostering higher standards in sustainable building practices.

The Role of BREEAM in Encouraging Sustainable Practices
“One of the first things that comes to mind when discussing building energy rating systems is BREEAM,” Lisa began, her enthusiasm for the topic evident. Originating in the UK, BREEAM (Building Research Establishment Environmental Assessment Method) is a pioneering force in the realm of sustainable construction. Since its inception, it has set the benchmark for assessing the environmental performance of buildings.
“BREEAM ratings range from Pass to Outstanding, and each level represents a commitment to higher standards in sustainable building practices,” Lisa explained. “Achieving an Outstanding rating is no small feat. It requires meticulous planning, innovative design, and a holistic approach to sustainability.”
Lisa elaborated on the various categories BREEAM assesses, including energy, health, materials, and pollution. “It’s not just about energy efficiency. BREEAM looks at the entire lifecycle of a building, from the materials used in construction to the health and well-being of its occupants. This comprehensive approach ensures that buildings are not only energy-efficient but also conducive to a healthier environment.”
LEED: A Global Standard for Sustainable Building
As the conversation shifted to LEED (Leadership in Energy and Environmental Design), Lisa highlighted its global recognition and widespread adoption. Developed by the U.S. Green Building Council, LEED has become synonymous with green building certification worldwide.
“LEED evaluates buildings based on criteria such as water efficiency, energy use, materials, and indoor environmental quality,” Lisa said. “The certification levels—Certified, Silver, Gold, and Platinum—provide a clear framework for measuring a building’s sustainability.”
Lisa pointed out that LEED’s strength lies in its adaptability. “One of the reasons LEED is so effective is its ability to be customised to different types of projects and climates. Whether it’s a high-rise office building in New York or a residential complex in Dubai, LEED provides a consistent standard for sustainable practices.”
The Synergy Between BREEAM and LEED
While BREEAM and LEED have their unique strengths, Lisa emphasised the synergy between the two systems. “Both BREEAM and LEED aim to promote sustainability, but they do so in slightly different ways. BREEAM’s strength lies in its holistic approach and detailed assessment criteria, while LEED’s adaptability and global recognition make it a powerful tool for promoting green building practices worldwide.”
Lisa noted that many developers and property owners opt to pursue both BREEAM and LEED certifications. “By combining the strengths of both systems, they can achieve a higher standard of sustainability and gain recognition in both local and global markets.”
Benefits of Energy Rating Systems
Our conversation naturally drifted towards the benefits of these energy rating systems. Lisa was quick to highlight the enhanced marketability that high energy ratings bring. “Buildings with high energy ratings are more attractive to buyers and tenants. They promise lower energy bills and a reduced environmental footprint, which are significant selling points.”
She also touched on regulatory compliance. “Meeting the standards set by BREEAM and LEED ensures compliance with local and national regulations. This not only avoids potential legal issues but also positions the building as a leader in sustainable practices.”
Improved building performance was another key benefit Lisa highlighted. “Regular assessments and certifications drive continuous improvements in building design, construction, and operation. This leads to better overall performance and a more sustainable built environment.”
Conclusion
As our conversation drew to a close, Lisa reiterated the importance of building energy rating systems in promoting energy efficiency and sustainability. “BREEAM and LEED are essential tools for developers and property owners. By adhering to these standards, they can enhance the value, performance, and environmental impact of their buildings, contributing to a greener and more sustainable future.”
Reflecting on my discussion with Lisa, it became clear that building energy rating systems like BREEAM and LEED are not just certifications—they are catalysts for change. They encourage innovation, drive continuous improvement, and ultimately, help create a more sustainable built environment for future generations.
