PROJECT HIGHLIGHTS: Anticipated to be in the top one percent of U.S. buildings for energy performance On target to become the region’s most energy efficient air conditioned building One of the first projects in the region to combine the use of geothermal heating and cooling systems with structural piles New products, including indirect light fixtures and chilled sails, developed and manufactured specifically for this project to help achieve aggressive energy targets All storm water captured and filtered on site through rain gardens Nearly 99 percent of construction waste recycled or salvaged

DESIGN APPROACH At the heart of the Federal Center South Redevelopment is the concept of an integrated workplace connected to nature. Inspired by the oxbows present in the original course of the Duwamish waterway, the U-shaped design creates a dynamic, highly sustainable 21st century environment for the U.S. Army Corps of Engineers (USACE). To reflect the USACE’s focus as an agency, the building is oriented toward the water and establishes an excellent contrast to the masonry of the adjacent historic 1201 building. The exposed ‘diagrid’ structure and mechanical systems add to the industrial aesthetic and exemplify the engineering rigor, strength and stability of USACE’s mission of “Building Strong.”

Existing Industrial Context

Diagonal columns create a distinct exterior form, and the extensive use of glass defines its sleek and modern aesthetic. The atrium offers a central gathering space – fostering collaboration and creating a sense of community – while extensive daylighting and views provide a distinct connection to the outdoors. The building is divided into four quadrants, which are named after the four rivers that historically came together to form the Duwamish River. Offices take shape on the outside of the oxbow and surround the atrium within. In between this space, three levels combine open areas with landscaping, greenery and water features depicting the natural surrounding environment.

Campus Open Space

With sustainability at the forefront, the design integrates active and passive systems, materials and strategies in new ways. Its optimized form and building orientation will place this building within the top one percent of energy efficient buildings across the country – without sacrificing comfort, amenities or innovative design. Organized around the life of the tenant, the building creates an optimal and modern environment, with spaces reorganized to reflect a new era of sustainable workplaces. The design accelerates interaction and collaboration, while the footprint enables flexibility for infinite subdivisions of program and work groups now and well into the future.

SUSTAINABILITY ELEMENTS Certifications & Benchmarks Targeting LEED Gold certification Energy Star score of 100 30% below ASHRAE 2007 benchmarks Meets requirements set forth by the 2030 Challenge

Energy Anticipated to be in the top 1% of U.S. buildings for energy performance Estimated energy use index (EUI) of 24 (standard office buildings in the NW have an EUI of 106) Energy management software and devices will be installed to monitor energy use

Water Rain gardens treat and filter all storm water on-site, eliminating the expense of connecting to the City’s storm water system The rainwater reuse system will capture water from the roof and store it in a 25,000 gallon cistern to be used for toilets, irrigation, a rooftop cooling tower and water features in the atrium Maximum efficiency ‘Water Sense’ fixtures utilized throughout the building

Lighting Optimization of floor depth and façade design enables extensive daylighting Lighting design targeting a very low ambient power density of 0.68 W/SF Occupancy sensors and continuous dimming ambient controls used for daylight harvesting, maximizing connection to nature, and reducing electric lighting loads during daylight hours

Sunshades utilized on every elevation and tailored to respond to specific solar conditions Site lighting with pedestrian scale poles are combined with low level lighting to provide safe and even light levels while highlighting architectural and landscape features

Heating, Cooling & Ventilation Use of geothermal heating and cooling combined with structural piles that average 160 ft. deep (one of the first projects in the region to combine both systems) Thermal storage tanks with phase-change materials store cooling energy for future use Shading devices to optimize performance for heat gain Under floor air and radiant cooling Ventilation air for the building provided by five rooftop air handling units with heat recovery Heating provided at the perimeter zones using the raised floor plenum air distribution and hydronic radiators Cooling primarily provided using passive chilled beams with a portion supplied by the ventilation air through the raised floor plenum

Materials & Resources Reuse of 200,000 board feet of structural timbers and decking from the existing warehouse located on site Over 98.8% of construction waste recycled or salvaged Low-emitting materials used throughout the building Over 20% use of recycled content materials and 50% use of certified wood

roof drains

source stone features On-site drainage runoff will be treated within rain gardens and detention ponds. The runoff will be collected around the perimeter of the site and directed to the westernmost pond, mimicking natural site drainage patterns and leveraging low-impact development techniques.

Site Development & Remediation Project located on Superfund site Wetlands and shoreline restoration, converting large areas of hardscape to green space Four acres of greenery is returning to the site Current soils amended rather than importing new material

Green Job Training & Strengthening Local Economy On-site green job training to enhance skills by learning new technologies and BIM techniques As a GSA requirement, approximately 35% of the companies involved in the project are minority-owned or small businesses

A GSA DESIGN EXCELLENCE PROJECT The Federal Center South Redevelopment project is funded through the FY 2009 American Recovery and Reinvestment Act (ARRA) and is part of the U.S. General Services Administration’s (GSA) Design Excellence program. It is the pivotal undertaking for a campus-like site redevelopment that will provide for the future space requirements of the tenant and accommodate the 30-year expansion requirements for a number of other Federal Agencies.

Sellen Construction and ZGF Architects were awarded the contract based on their relevant experience and progressive integrated design approach, showcasing creative and effective design and construction strategies. The team was also selected for their ability to achieve the goals and aggressive energy targets set forth by GSA and the tenant, by implementing substantial measurement and verification plans to track energy consumption during operation.

Approach for the Federal Center South Redevelopment

GSA’s progressive sustainability requirements and highperformance benchmarks include the following:

In order to expedite the delivery to meet ARRA deadlines, a Design-Build (DB) procurement was utilized. The DB team was selected via a two phase process: a review of technical qualifications and past performance, followed by a concept design competition presenting an initial design concept. Competing shortlisted teams needed to demonstrate how they would achieve energy reduction goals as part of awarding the project. The team’s contract with GSA includes an incentive payment to be awarded once the building demonstrates achievement of the EUI energy performance goal.

Achieve a minimum of LEED Gold certification Attain an Energy Use Index (EUI) of 27.6 kBtu/sf/year Utilize 100% filtered outside air Meet an Energy Star Score of 97 Energy Performance must be 30% better than ASHRAE 90.1 2007 edition 35% of companies involved must be small businesses or minority-owned Pass a one-year performance evaluation to guarantee energy targets were met

Design Excellence Program Overview GSA manages architects and engineers to provide design for federal clients needing new workspace. To achieve top-quality design talent, GSA instituted the Design Excellence Program, which includes a streamlined two-step architect/engineer selection process and the use of private-sector peers to provide feedback to the architect/engineer of record. The Design Excellence Program operates through GSA’s Public Buildings Service (PBS). The PBS directs the federal government’s multibillion-dollar building program, which includes construction, renovation, alteration, and repair of federal office buildings, courthouses, and other facilities.

The west exterior plaza is an outdoor amenity for building occupants and an extension of the Commons that creates a strong inside-out/outside-in relationship between the building and campus.
