Sustainability Consulting

Tetra Tech's High Performance Buildings Group is building a resilient future through sustainable design. Our global team of building design experts provides solutions that improve the value, resiliency, and efficiency of our clients' projects and the growing cities in which we live and work.

We understand the inherent value of developing sustainable buildings and aim to optimize building efficiency and promote sustainability as an integral part of all our projects. The members of our High Performance Buildings Group are experts in the design of fully integrated systems that deliver efficient solutions with best-in-class outcomes—from reduced operating costs and improved health and well-being for occupants, to higher profit margins and market differentiation.

Throughout the project life cycle, from design through construction, our sustainability team offers guidance and technical expertise to realize our clients’ vision in a manner that fosters environmental stewardship and remains cost-effective. Our sustainable design experts provide clarity and guidance on effective integration of energy-efficient, low-carbon systems. Drawing inspiration from the Earth’s natural processes, we incorporate natural ventilation, daylight harvesting, radiant solutions for heating and cooling such as in-slab radiant flooring and active or passive chilled beams, on-site solar energy, and on-site geothermal energy. We are committed to the planning, design, construction, and operation of sustainable buildings, towns, and cities around the world. Our experts have worked on a significant portfolio of projects throughout Asia, Australia, Canada, Europe, New Zealand, and the United States.

Tetra Tech is a proud leader in sustainable design. Our staff includes professional engineers, LEED Accredited Professionals (APs), Certified Energy Managers (CEM), Building Energy Modeling Professionals (BEMP), WELL APs, and a growing roster of Living Building Ambassadors. We also are long-time, active members in the leading green building organizations in the United States—the U.S. Green Building Council, the WELL Building Institute, and International Living Future Institute—and are early adopters of the Green Building Council of Australia.

Our mechanical, electrical, and plumbing (MEP) engineers, energy analysts, sustainability consultants, lighting designers, and commissioning agents help our clients create healthy buildings for their customers. Tetra Tech’s sustainable design team has also guided hundreds of buildings toward LEED certification, WELL certification, and Green Star rating and is delivering a growing list of certified net zero energy and net zero water facilities. We also are ongoing sponsors of the International Living Future Institute and are adding a growing list of Living Building Challenge certified projects to our portfolio. Many of these buildings are firsts of their kind, including the first residential high-rise building in the United States to earn LEED Gold; the first LEED Platinum v4 office in East Asia, the first Living Certified Reuse project in the world; the first Net Zero Carbon educational facility in Australia; and Harvard University’s first LEED-certified building on the campus.
