Unico Sustainability has successfully completed the City of Seattle’s Deep Green Pilot Program for Stone34, a Unico-owned and managed- building in the Fremont neighborhood of Seattle, surpassing the Deep Green Pilot Program’s (DGPP) rigorous sustainability benchmarks to become one of Seattle’s most energy and water-efficient buildings.
“Congratulations to all who helped make the Stone34 project a success within Seattle’s Deep Green Pilot program,” said Seattle Mayor Ed Murray in a September press release. “Through strong partnerships between environmental advocates, developers, and policy makers, we are encouraging innovative commercial development strategies that reduce environmental impacts, test new technologies, and serve as a model for more sustainable development in Seattle and across the country.”
Brett Phillips, Director of Sustainability, noted the exciting potential that the success of the project brings to Seattle and the real estate industry. ”We’re honored to work with the City of Seattle and our valued partners to pioneer a new policy that will unleash greater investment in environmentally responsible and financially prudent development.”
“The incredible sustainability achievements and success at Stone34 represent a milestone for the built environment and provide a detailed blueprint for future commercial developments to replicate,” added Brett.
Now known as the Living Building Pilot Program (LBPP), the Deep Green Pilot Program was developed using components of the Living Building Challenge which is administered by the International Living Future Institute (ILFI) and whom the City of Seattle uses as a third-party verifying body. Under the program, Stone34 was afforded additional building height in return for committing to meet the program’s green building requirements. Relative to average comparable commercial buildings, Stone34 was required to curb energy and water usage by 75 percent, and reuse 50 percent of captured storm water as well as achieve 12 out of 20 of the imperatives outlined in ILFI’s Living Building Challenge.
Unico was responsible for managing the DGPP performance effort for Stone34; key partners included anchor tenant Brooks Running, whose early and continued commitment to the project was been integral to its success; developer and builder Skanksa USA who partnered with LMN Architects to create the building’s unique sustainability features; and McKinstry, the project’s design-build mechanical and plumbing partner.
At the culmination of the 12-month performance period, Stone34 exceeded the energy, water, and stormwater-reuse requirements outlined in the program. Energy use for the building was 15.4% better than the DGPP requirements and water use was an astounding 27% better than required. These successes would not have been possible without the efforts of anchor tenant Brooks Running, who encouraged employees to compost, shorten showers with the help of smart timers, and manually adjust window treatments to maintain a comfortable building temperature, among other behaviors.
“When we moved Brooks’ global headquarters to Seattle, our goal was to find a building that connected us to the heart of the running community, inspired our employees and reaffirmed our dedication to the environment,” said Jim Weber, CEO, Brooks Running Company. “Stone34 isn’t just another address, it’s a thought-leading example of how businesses can live and thrive in deep-green buildings in the heart of a city.” Don’t miss the the video Brooks produced that takes a look at the project from start to finish.
Additional partners who contributed to the success of the project include landowners Fremont Dock Company; DCI Engineers as the project’s structural engineers; Swift Company as the landscape architect; WSP Flack & Kurtz, which provided mechanical/plumbing design during development; KPFF Consulting Engineers which handled the civil engineering; and Cochran which performed the electrical work. The other retail tenant at Stone34 is MiiR, whose flagship store features craft beer, coffee and retail that goes to support the development of water and transportation in less developed areas of the world.
Sustainability elements and achievements at Stone34 include:
- Stone34 is a dual-certified LEED building earning Platinum certification for Core & Shell on the design and construction as well as Platinum certification for Operations & Maintenance;
- ENERGY STAR score of 100;
- During construction, 97 percent of construction materials were diverted from landfill;
- A reader board in the Brooks Running’s “Beastro Café” tracks the building’s energy and water usage in real-time; an art fixture entitled “Fissure” located in the building’s lobby responds to the building’s energy usage “blooming” when power use is low and “wilting” when it’s high;
- A state-of-the-art mechanical system integrates chilled beams, air and water heat recovery systems, and a thermal storage tank, and a highly insulated thermal envelope;
- The site was restored with more than 7,000 square feet of native vegetation and urban agriculture including lavender, oregano, rosemary, strawberries, hops and thyme;
- A 65,000 gallon rainwater cistern collects and reuses stormwater for irrigation, flushing toilets, and feeding the cooling tower;
- Locally-designed sculptural bike racks with enough space for 30 bikes, 12 electric vehicle charging stations, stretching bars, drinking fountains, and shower facilities support alternative transportation and cater to tenants who run, bike or drive electric vehicles to work.
