SUBJECT:  Environment and Sustainability in Capital Projects 
EXECUTIVE SUMMARY 
The Port of Seattle prioritizes high standards of environmental sustainability, serving the
welfare and the interests of our community. Every capital project the Port undertakes reflects
our environmental values. Some projects have environmental benefit as their main purpose,
such as remediating legacy contamination, restoring or creating habitat, conserving energy or
reducing greenhouse gas emissions.  Even for projects principally driven by commercial or
customer service objectives, we seek in every case to minimize adverse environmental impacts
and to advance goals such as conserving energy, minimizing construction waste, conserving
water and minimizing adverse impacts. Advancing our environmental objectives in all our work
reflects the ethos of the Pacific Northwest and the values of our community.  This briefing
highlights three example projects: Pier 69 Solar Panels, International Arrivals Facility (IAF) and
North Satellite Renovation (NSAT). 
EXAMPLE PROJECTS 
Pier 69 Solar Panels is an example of a project undertaken to convert energy supply to a
renewable source.  The IAF and NSAT are major projects with multiple environmental and
sustainability features which the Port is documenting by pursuing Leadership in Energy and
Environmental Design (LEED) certification. 
Pier 69 Solar Panels 
The solar array was installed on the roof of Port headquarters, a three-story 191,000 square
foot-structure that was built in 1931.  The sloped metal clad roof exposes directly to the south
making Pier 69 the ideal location to install the solar array.
The Project received grant funds from the State Department of Commerce offsetting half the
construction costs.  The Monocrystalline PV panels were constructed in Washington  and
installed by local Puget Sound Solar, support the local and Green Tech economy in the state.
The system is designed to generate approximately 127,000 kWh annually resulting in an offset

of greenhouse gas emissions by 1.8MtCO2 annually and operational savings of approximately
$10,000 in energy costs per year. 

International Arrivals Facility 
The IAF replaces overcrowded and outdated international arrivals space in the basement of the
South Satellite with a world-class facility capable of processing 2,600 passengers per peak hour
and a Minimum Connect Time (MCT) of 75 minutes. The project is pursuing LEED V4 Silver
certification. Features of the IAF project include: 
(1) Design maximizes daylight to interiors while controlling glare 
(2) Ground location of mechanical equipment enables  sloped roof shape to improve
daylighting and views 
(3) Enhanced indoor air quality strategies 
(4) Energy savings with LED lighting, roofing material 
(5) Low-flow plumbing fixtures and outdoor water use reduction 
(6) Construction waste management and recycling 
(7) Enhanced commissioning procedures. 
North Satellite Renovation 
The North Sea-Tac Airport Renovation (NorthSTAR) Program is a collaborative effort of the Port
and Alaska Airlines (AS) to improve traveler experience and customer service.  The North
Satellite (NSAT) Modernization project is the largest segment of the NorthSTAR Program,
expanding of the North Satellite from 12 to 20 contact gates, modernizing the existing North
Satellite facility, and expanding the baggage system to accommodate the satellite expansion. 
Like IAF, North Satellite Renovation is pursuing LEED Silver certification.   Environmental
features of the project include: 
(1) Water conservation through rainwater capture and low-flow toilet fixtures 
(2) Energy savings 17% below code through 
a.  LED lighting 
b.  Daylight optimization 
c.   Insulation and glass 
d.  Electric motor efficiency 
(3) 95% of construction waste diverted from landfills.
