Design that respects and restores our environment.

Sustainability

We know sustainability means different things to different people. Whether it’s energy efficiency that matters most to our clients, or healthy indoor air and nontoxic materials— we’ve got all of it covered. Sustainable design is built into our practice.

One of the things we’re most proud of is that, for decades, we’ve led the AEC industry toward exceptional environmental performance. And this leadership has caused a sea change in the way places and spaces are designed and constructed all around the world. Our goal? To keep lighting the way forward.

Living Design

We envision designing a world that creates healthier, thriving ecosystems for all. Our research-backed Living Design framework combines sustainability with other vital elements of a holistically high-performing environment.

High-Performance Buildings

Our SPEED platform is a state-of-the-art digital tool that helps design teams maximize a project’s energy efficiency in a fraction of the time. Created in partnership with the U.S. Department of Energy, SPEED allows for considerable upfront and long-term savings for our clients, not to mention exceptional environmental performance.

Carbon Leadership

We helped develop the industry’s most comprehensive free tool for embodied carbon measurement in the built environment. The Embodied Carbon in Construction Calculator, or EC3, makes selecting low-carbon materials simpler than ever. By quantifying the carbon impacts of our material selections and supply chain decisions, EC3 helps us radically optimize building performance.

Mass Timber

Our rapidly growing portfolio of timber environments is paving the way for a new generation of sustainable architecture and design. Engineered wood is the new frontier of healthy living, working, and learning.

Carbon-Neutral Business Operations

We’ve always led by example, and our own business operations are a good case study. Over a decade ago, we pledged to reduce our greenhouse gas (GHG) emissions in a meaningful, measurable way. By scaling back our business air travel, achieving a minimum of LEED Gold certification for all of our design studios, reducing our use of paper products, and investing in Green-e Certified Renewable Energy Credits (RECs) and carbon offsets, we achieved firmwide carbon neutrality in 2007.

Transparency

We understand that human and planetary health are inextricably linked, and that buildings can have a major impact on both. That’s why we ignited an industry movement in 2008 toward healthy building materials with our Precautionary List and, later, our Transparency portal.

Material Health

Almost two decades of leadership in advocating for the transformation of building products led to our industryleading role within the mindful MATERIALS Collaborative. The mindful MATERIALS Library is a free digital platform that allows design teams and industry professionals to search for products that meet third-party, health-based certifications, declarations, and validations.
