A sustainability showcase

As a showcase for environmental stewardship, 35 Stone embraces the Seattle Living Building Pilot Program, pursuing the Place, Beauty, and Materials petals of the Living Building Challenge and ambitiously reducing energy and water use.

PNW to the core

The building leverages the strength of a Dowel Laminated Timber (DLT) floor system with a glulam structural frame that reduces the building’s carbon footprint compared to steel and concrete construction. The warmth of the Douglas Fir interior provides a visual reminder of the building’s connection to nature and honors the region’s historic timber industry.

Biophilic benefits

Beyond the extensive timber interior, numerous operable windows, balconies and outdoor terraces promote access to daylight and fresh air. Visual access to the surrounding landscape and neighborhood serve as a connection to the natural world – proven to boost occupant health, mood, cognitive function and overall performance, ultimately benefiting office tenant employees.

Interactive education

Educational signage describes landscape elements and features relating to the Living Building Challenge while interpretive ‘benchmarks’ in the entry courtyard express the building’s performance. An interactive dashboard in the lobby displays real-time metrics focused on water and energy usage, and carbon goals.

Rainwater harvesting

Rainwater – a precious resource in the Pacific NW – is captured in a 250,000-gallon cistern, filtered and reused for toilet flushing and on site irrigation.

A home for bees & bikes

At the entrance to the building, a honeycomb-like timber canopy welcomes employees and visitors. It foreshadows a feature they’ll discover on site: a ‘periscope’ that provides a peek into the honeybee apiary on the roof of the building.

Just a block from the Burke-Gilman trail, 35 Stone’s emphasis on bike amenities was a priority from day one; the building houses a large bicycle lounge and locker room to entice people to engage in a two-wheeled commute to work.

35 Stone sets a precedent for what a healthy, sustainable PNW office building can be.

Sustainability

Building upon the success of nearby DATA 1 and Watershed commercial office buildings, 35 Stone is participating in the Seattle Living Building Pilot Program (LBPP) for height and area incentives and expedited permitting. The building is pursuing the Materials, Place, and Beauty Petals of the Living Building Challenge and incorporates extensive rainwater catchment strategies and energy efficiency measures to meet the robust LBPP requirements.
