State Energy Savings Performance
Contracting Process: 
1.Outline scope of work to audit 
2.Enter agreement with State ** 
3.Contract with ESCO ** 
4.ESCO performs energy audit and provide
guaranteed costs and savings 
5.Contract with ESCO to design and construct
viable measures ** 
6.Measurement and verification 
** Commission Approval Required

Commission Schedule  Stage 3 
March 2014: Request for Energy Audit funding 
Analyze and develop conservation measures
including, costs, savings and preliminary designs 
December 2014: Request for Design and
Construction funding 
Design and construct those conservation measures
that meet the minimum performance criteria

Project  Stage 3 
Anticipated Improvements 
Replace constant volume with variable volume
air handling terminal boxes 
Chilled water system pumping optimization 



Existing Equipment

Project  Stage 3 
Anticipated Improvements 
Occupancy adjustments for controlling building
ventilation 
Air curtains to reduce air flow in/out of main
terminal

Project  Stage 3 
Project Budget 
March, 2014 Authorization Request $ 349,440 
Total Estimated Project Cost $3,500,000 
ESCO Projects are Low Risk 
The performance of each Energy Conservation Measure
(ECM) is independently evaluated 
ECMs must guarantee a 10% ROI or the Port has no
obligation to proceed or pay associated fees
Port of Seattle Financial Risk 
$25,700 Termination Fee 
ESCO Design Fees $0 - $199,440 
Port Project Management Costs $150,000 
Project costs and savings will be included in
terminal costs paid by airlines
