Seattle’s Living Building Pilot Program (LBPP), 3rd building overall to pursue the program. Others are The Bullitt Center and Stone 34.

Watershed, a proposed commercial office building in Seattle’s Fremont neighborhood, will be the only building to pursue the 2014 version of Seattle’s Living Building Pilot Program (LBPP). 
The vigorous water scrubbing strategies of the two sites qualify each for Salmon-Safe Certification. 
Salmon-Safe works to keep our urban and agricultural watersheds clean enough for native salmon to spawn and thrive.

The project includes a 7-story, approximately 61,000 SF office building with approximately 5,000 SF of retail at grade. Two frontages include vibrant pedestrian environments as well as treatment of stormwater from the historic Aurora Bridge. Located at the corner of Troll Avenue N and N 34th Street it will link the core of Fremont with new developments on Stone Way. Watershed was recently recommended to proceed to Master Use Permit by Seattle’s Northeast Design Review Board. Construction is targeted to begin in November 2017.

Watershed is pursuing Petal Recognition from the International Living Future Institute (ILFI) focusing on the Materials Petal, in addition to supplemental energy reduction, potable water reduction, and stormwater reuse targets required by the City of Seattle to participate in the LBPP. Healthier materials in a simple palette will be specified, favoring products and materials that are LBC red-list compliant, have an ILFI Declare Label listing product ingredients, and are locally sourced.

While the Materials Petal is the primary hurdle for LBPP participation, the approach to stormwater management is a large part of the project story. Two pedestrian frontages along the street edge will include landscaping to treat over 300,000 gallons of runoff from the Aurora Bridge and Troll Avenue, diverting it into a series of stormwater retention and biofiltration swales before it is collected into a dedicated storm drain with an outfall to Lake Union. Additionally, the building will collect and reuse more than 200,000 gallons of roof water annually.

Watershed is an extension of the right of way improvements on Troll Avenue that were begun by nearby Data 1 Office Building. COU LLC,  is developing both projects. The vigorous water scrubbing strategies of the two sites qualify each for Salmon-Safe Certification.

After seven years of the Seattle Living Building Pilot program, Watershed will be only the third project to pursue the program. The two other buildings to pursue and qualify for the program were The Bullitt Center and Stone 34.

The Bullitt Center, a six-story, 50,000 square foot office building in Seattle that aspires to be the world's greenest commercial building, opens its doors to the public today on Earth Day. This $30 million "living laboratory," designed by Miller Hull Partnership, distinguishes itself from other sustainable projects with its composting toilets, the exclusion of 350 common toxic chemicals - including PVC, lead, mercury, phthalates, BPA and formaldehyde - along with a strict energy and water budget that aims for self-sufficiency under the Living Building Challenge. The environmentally-conscious Bullitt Foundationhopes that the new center will demonstrate that carbon-neutral office space can be "commercially viable and aesthetically stunning," a series of systems that can be easily copied elsewhere without being overly demanding in upkeep.



Stone 34

Empowering both developer and tenants to reduce energy and water consumption.


Stone34 is the pioneering project in Seattle’s Deep Green Pilot Program, a platform to encourage the use and acceptance of deeper, sustainable development strategies. While Stone34 earned early accolades as one of the most efficient commercial office buildings in the country, Brooks chose Stone34 for its new world headquarters because they wanted to change their office behavior, and possibly influence other companies in the process.

At conception, Stone34 was designed to reduce water and energy by more than 75% of other comparable buildings, and capture and use at least 50% of stormwater on site. For Stone34 to meet the Deep Green requirements, Brooks had to be on board for monitoring energy and water use. To help, Stone34 provides monitoring tools for tenants to measure energy consumption.

Additionally, Stone34 provides an advanced “thermal envelope” to allow holding in heat in winter and cool air in summer, as well as technical elements like hydronic heating and chilled beams to keep the interior comfortable for tenants and visitors. Click the image below to explore the details.
