ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to prepare design and
construction bid documents for the Parking Garage Lighting project at Seattle-Tacoma
International Airport. This authorization  is for $1,243,000 of a total estimated project cost of
$6,235,700. 
SYNOPSIS 
This project is an energy conservation project that will retrofit all the lights on normal power
circuits, on all eight floors in the parking garage. By utilizing new LED lighting technology,
energy consumption can be reduced by over 60% while still providing the same lighting levels.
In addition, this project will install additional lighting on the first floor and in the fourth floor 
plaza area to increase light levels and provide a better customer experience. This project was
included in the 2014  2018 capital budget and plan of finance. 
BACKGROUND 
Lighting technology in the parking garage is over 15 years old. New LED technology enables
lighting levels to remain the same while decreasing energy consumption. In 2013, we reduced
energy consumption by 60% by retrofitting fixtures on the emergency circuits. This project will
retrofit the remaining fixtures in the garage to realize the same energy savings for lights on
normal power circuits.

Budget Status and Source of Funds 
This project (C800581) was included in the 2014- 2018 capital budget and plan of finance with a
budget of $5.0 million.  Upon completion of the notebook, the cost to accomplish the lighting
replacement increased by approximately $1,235,700. The budget increased as a result of several
factors. First, new scope totaling $334,000 was added to the project to improve light levels on
the 4th Floor Plaza area. Second, the original cost estimate did not account for the need to
increase light levels on the 1st floor that are necessary to bring that floor up to current building
code requirements or the need to replace rather than retrofit the existing 1st floor light fixtures.
The additional work on the 1st floor accounts for the remaining $901,700. In addition, scope was
added to increase the number of lighting fixtures on the first and fourth floors to achieve the
same standard of illumination on the other floors. This will add approximately $704,000 to the
cost. The cost increase will be transferred from the Non-Aeronautical allowance CIP, C800405,
resulting in no net change to the Airport capital budget.
The funding sources will include the Airport Development Fund and future revenue bonds. The
Port anticipates issuing revenue bonds in late 2014 or early 2015 to fund multiple projects.
Financial Analysis and Summary 
CIP Category             Renewal and Enhancement 
Project Type              Renewal and replacement and customer service 
Risk adjusted discount rate     7% 
Key risk factors             Low risk 
Project cost for analysis        $5,532,000 (cost excluding additional light fixtures) 
Business Unit (BU)          Landside 
Effect on business performance  When all floors are completed, it is anticipated that annual
energy savings will exceed annual depreciation resulting
in an increase in NOI. 
IRR/NPV             NPV = $1.2 million, Modified IRR = 11% 
CPE Impact             None 
The financial analysis is based on the scope and cost of retrofitting lighting fixtures to achieve
energy savings (excludes scope and cost for added light fixtures) and assumes a total of $750,000
in incentives and grants are received (see below). Energy savings have been calculat ed using the
Tier II rate from Bonneville Power Administration. At the margin, this is the rate that will be in
effect in future years if energy savings are not realized.
Lifecycle Cost and Savings 
This project qualifies for $250,000 in Bonneville Power Administration (BPA) conservation
incentives and has been awarded a $500,000 grant from Washington State Department of
Commerce (DOC). The DOC grant award is assured as long as the project has started
construction by June 2015.

It's anticipated that the yearly ongoing O&M costs for the parking garage lighting will decrease
beginning in years 2016 2018 as the garage lighting is replaced (phased in) utilizing LED lights.
Year 2019 should have only minimal (incidental) O&M costs related to garage lighting. 
Beginning in 2020, if the Port chooses not to replace the LED retrofit fixtures with a new
technology it is anticipated that the Aviation Maintenance department will be experiencing repair
and replacement costs ranging from $250K -$466K per year to replace the LED lamps and repair
or replace fixtures over a period of approximately nine years. 
STRATEGIES AND OBJECTIVES 
This project aligns with the Port's objective to be the greenest, and most energy efficient port in
North America by meeting all increased energy needs through conservation and renewable
sources. 
TRIPLE BOTTOM LINE 
Economic Development 
The project supports economic development by investing in an upgraded parking garage to serve
the public need at the Airport and it helps the environment by reducing energy consumption at
the Airport. 
Environmental Responsibility 
This project will provide the opportunity to apply environmental sustainability principles
primarily through the use of energy-efficient light fixtures. These will reduce the energy use by
an estimated 60% while providing more than four times the lamp operating life compared to
what is currently installed. 
Community Benefits 
This project aligns with the Port's objective to minimize the Airport's environmental impacts
and reduce energy demand through conservation while operating a world-class international
airport by ensuring safe, secure, and sustainable operations. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Do nothing. Do not implement this project.  This is not the recommended
alternative because energy will be wasted and the Port may not meet its goal of supplying all
new load growth with conservation. 
Alternative 2)  Implementing this project with the best available technology will help the Port
reduce energy consumption and supports our Century Agenda goals. This is the recommended
alternative.
