SUBJECT:   Special Order of Business - Seattle City Light (SCL) Incentive Check
Presentation to Port of Seattle for the Consolidated Rental Car Facility 
SYNOPSIS: 
Mr. Jorge Carrasco, Superintendent of Seattle City Light (SCL), will attend this meeting
to present the Port with an incentive check in the amount of $408,275 for an overall
energy savings exceeding 2,150,541 kilowatt-hours (kWh) per year at the Rental Car
Facility (RCF) as part of SCL's Energy Smart Service Program, which pays up to 70% of
costs for retrofits and new equipment purchases that save energy. The rebate is based on
the project's first-year kWh savings. In addition to the energy savings, the annual
operational savings realized through participation in the program are estimated to be
$135,484, and the RCF's greenhouse gas emissions are reduced by an estimated 1,290
tons/year.
The Port, rental car companies, and SCL began collaborating in 2006 during the design of
the RCF, as an associated effort to the RCF being designated the Airport's sustainable
asset management demonstration project and seeking certification in Leadership in
Environmental and Energy Design (LEED), to incorporate energy-efficient features into
the facility identified below. The project has now joined a select group of sustainable and
state-of-the-art projects locally that manifest efficient electrical design practices to meet
specified  energy  saving  standards  and  reduce  the  negative  impact  of  buildings' 
consuming electrical energy on the environment. The amount of $408,275 will offset
Customer Facility Charge (CFC) funding, reducing the CFC's used for the project. Port,
rental car company representatives, and SCL staff will also be present to be recognized
for their significant effort in obtaining this incentive payment. 
BACKGROUND: 
The RCF project was designated the Aviation Division's sustainable asset management
demonstration project in 2005 during the preliminary engineering phase. During design,
the project established a goal to implement a 'total cost of ownership' decision-making
framework that would positively impact construction and operation of the facility. The
project used lifecycle cost analyses as evaluation criteria for major equipment and
systems, eco-charrettes, and guiding principles of 'right sizing' the facility as strategic

measures. A LEED checklist was used as a guideline during the preliminary and final
designs. In addition to operations and maintenance, the team also considered any impacts
to rental car operations. 
After the 60% design submittal, the decision was made to seek a 'Certified' rating under
the LEED New Construction 2.2 system. Associated with the decision to pursue LEED,
Port staff investigated and approached SCL about the potential of the RCF qualifying for
the Energy Smart Service Program.  The Port and SCL entered into a formal agreement
on May 11, 2010. The RCF opened on May 17, 2012.
The Port provided specific design calculations and equipment performance information to
SCL. In addition, the Port provided construction cost information for five key energy
efficient systems and components to SCL via the contractor as part of SCL's program
verification process. As a program requirement, SCL was required to fully evaluate and
inspect the completed facility approximately six months after opening to determine if the
Port had met its obligations under the agreement and for SCL to determine the actual
energy usage and resultant savings. The overall energy usage has well exceeded the
expected energy savings, resulting in a 2,150,541 kWh/year saving and an estimated
$135,484 in operational savings per year.  Additionally, the RCF energy-saving features
reduce greenhouse gas emissions by an estimated 1,290 tons per year. 
Features implemented that contribute to energy savings include: 
Reduction in floor plate mechanical ventilation by using natural ventilation
strategies and CO2 sensor-controlled ventilation systems on the floor plates 
Right sized building space to reduce continuous mechanical heating/cooling by
approximately 33% 
Energy efficient heating/cooling equipment including variable speed drives on the
air handlers, and air cooled chillers 
Energy efficient substation transformer and distribution transformers 
High efficiency lighting with automated occupancy sensor controls throughout
facility 
Day lighting strategies in the customer service building and operational floor
plates 
Painting floor plate ceilings white to reduce the number of light fixtures installed 
SCL's Energy Smart Services Program focuses on business customers on their medium,
large or high-demand rate schedules. The program pays up to 70% of costs for retrofits
and new equipment purchases that save energy. The rebate amount is based on a project's
first year kWh savings. This program is the most cost effective way to meet the City's
future electricity needs. Incentivizing customers avoids the expense of building new
electric generating facilities or buying electricity on the open market. Currently, the Port
is City Light's eleventh largest consumer of electric energy within its territory.
