Living Building Challenge (Materials Petal)
Strategy & Services: The Natural Resources Defense Council’s (NRDC) San Francisco office pursued both LEED v4 Gold Certification and Living Building Challenge (LBC) Materials Petal Certification. The space, which embraces the NRDC’s mission of creating a sustainable and healthy environment, takes up two floors of 111 Sutter Street, a 25-story historic high rise in San Francisco’s Financial District. It is one of the first tenant improvement projects to take on the immense challenge of pursuing both ratings systems. Becoming the first LEED certified tenant improvement project in the city over a decade ago, the NRDC was up for the challenge under the freshly released LEED v4 and rigorous LBC rating systems. Primarily providing LEED v4 consulting and project management services, stok brought extensive experience in healthy, sustainable materials to help the project team succinctly achieve demanding materials requirements from both rating systems.
Design Details: Leading the aggressive pursuit of nearly every LEED v4 materials credit, stok’s mastery of healthy and sustainable materials allowed us to create a streamlined approach for LEED v4 and LBC material vetting. This helped the rest of the project team when reaching out to manufacturers, making the process succinct and cohesive. The materials strategy prioritized reuse, followed by a focus on Red List-free and Declare labeled products to ensure a healthy indoor environment for occupants. Beyond healthy materials, the office strives to create a better space for occupants with operable windows throughout, optimizing natural ventilation and light.

Outcome: The project achieved LEED Gold and the Living Building Challenge Materials Petals, fully aligning with the NRDC’s pursuit of sustainable, healthy environments. With its emphasis on reuse, the project reduced waste, harmful pollutants, and cost, while contributing to both the local economy and ecology through a comprehensive materials strategy.
