Stormwater Management

The best stormwater management systems mimic nature, integrate with the building and site design, and help reduce the damaging effects of urbanization. Directing runoff to natural drainage systems like green roofs, rain gardens, infiltration beds, landscaped planters, and bioswales reduces flow and provides time for the runoff to be naturally cleansed before entering ecosystems. Implementing natural drainage practices also helps restore groundwater supplies, improve water quality, increase local biodiversity, and stabilize microclimates.

The GreenHouse Apartments development integrates creative stormwater systems into the building and site to manage runoff while blending with the project aesthetics.

The comprehensive stormwater management system at Cherry Crest Elementary uses the site's natural landscape features as bioretention areas to mediate stormwater without installing costly detention tanks.

To support Amazon's vision of creating a truly green headquarters campus, stormwater management techniques took the shape of outdoor art pieces, terraced rain gardens, and large landscaped planters that reflect and celebrate the company's commitment to sustainability.

By taking advantage of an existing wetland on the school campus, stormwater management at Riverview Elementary not only rehydrates the site but teaches students environmental stewardship by promoting a strong relationship to the natural environment.

Water Management

Municipal potable water supply systems consume significant amounts of energy. We work with clients to determine the feasibility of implementing sustainable water strategies involving rain water harvesting to achieve environmental benefits, reduce water usage, and provide net energy savings.

The rain water harvesting system at The Bertschi Center includes a green roof and large cisterns that collect rain water that is re-used for irrigation and toilets.

Designed for net-zero water use, Valley View Middle School boasts a 100,000 gallon rainwater collection system that features a folded "butterfly" canopy that helps direct rain water into a large cistern that serves as a focal point at the school's entrance.

Water efficiency upgrades and the incorporation of a 10,000 gallon water collection system at the EMP Administration Building has resulted in a 75% decrease in water usage.

Building Form and Adaptable Structures

We understand the critical importance structure plays in achieving project goals. We seek to strike a balance between the desire to limit material consumption through economical design with other factors such as occupant comfort, daylighting requirements, natural ventilation goals, enhanced thermal envelope concerns, and adaptability through multiple generations of use. We have significant experience with the design of complex integrated façade systems often necessary to achieve optimal energy performance.

All the major programming and services for the University of Washington's HUB open onto the building's three-story atrium allowing for maximized daylighting while providing ample openings for natural ventilation, reducing energy use for lighting and mechanical systems.

Arched glulam roof beams from the original school were salvaged and used as columns for the new Machias Elementary, supporting the District's sustainable goals by limiting new building materials.

The complex cladding on Western Washington University's Academic Instruction Center is comprised of multiple systems in order to maximize daylighting while limiting the building's direct heat gain.

The adaptive-reuse of the 1915 Terry Avenue Building at the heart of Amazon's South Lake Union Campus reinvented the historic unreinforced masonry building into a new energy-efficient home for three Tom Douglas restaurants.

The use of FSC-certified heavy timber at the Tulalip Administration Building not only honors the tribe's rich heritage but also significantly reduced the carbon footprint of the building.

Spreading the Word About CLT

From supply to design to construction, we realize the sustainable, aesthetic, and modular benefits of this innovative material. In addition to engaging with associations, our firm has actively contributed to ongoing research and presented our findings nationally. We’re working with a confidential national developer to use CLT on an industrial scale across a wide variety of building types.

We recently wrote about CLT – its standout international projects, its momentum in Seattle, and its wow factors – in The Red Line here:

A 96,000-square-foot hub of interdisciplinary research and education in renewable materials, sustainable design, water quality and atmospheric research.

Collaborated with LMN to use cross-laminated timber panels throughout the building’s prominent public areas, lowering the carbon footprint and expressing engineered lumber materials, which WSU has helped develop for decades.

Exposed on the interior, the library’s CLT roof provides openings to maximize daylighting and is offset by glulam beams coated with a high-grade lamination.

The custom truss comprised of a glulam top core and a steel “V’ web transfers loads to the sloped columns on the perimeter, creating a spacious interior.
