This was dramatically demonstrated in 2000 at Seattle–Tacoma International Airport (Sea–Tac) when natural gas prices increased 8,000% and the annual energy bill climbed from $5 million dollars to more than $17 million in one year (CAP 2004)

Survey results varied depending on the size of the airport and type of system, with an overall greater percentage of respondents indicating some type of boiler replacement to improve efficiency. Cost/Payback/Savings: Airports surveyed reported that boiler-related energy efficiency improvements provided a 0- to 5-year payback and could be achieved for a range of costs -- from low to high.

Plate and frame heat exchangers installed at Seattle Tacoma International Airport (Sea–Tac) in 2004 were notable because of their projected savings of more than $1,000 per day and installation by engineering staff in "the equivalent of a weekend." Payback based on projections was less than one year (CAP 2004)

The investigators experience with more than 30 years of aviation architecture tells us that at most airports data and communications rooms continue to increase in size and cooling demand owing to more advanced building automation and communications. Survey respondents noted limited energy efficiency efforts applied to this type of system; however, as with other cooling components, older systems will benefit from greater efficiency when upgraded.

Cost/Payback/Savings: Survey respondents indicated a payback of 0 to 5 years and low implementation cost. Controls and Sensors Estimates of 15% to 45% reductions in yearly energy savings can be found when lighting controls are properly "specified, installed, commissioned and operated" (Benya et al.

Cost/Payback/Savings: Literature noted that less than 1-year payback can be expected through energy savings and reduced staff monitoring; however, some respondents noted payback of 5 to 10 years and low to medium cost. ELECTRICAL LOADS In addition to lighting, visual displays and conveyance systems are prominent consumers of energy within airport terminals.

BAS can be utilized for flight information display system and baggage displays. Display Retrofit $⎟ - Retrofit of CRT and other outdated visual displays used for flight information display system, baggage, parking, and advertising with energy efficient display technology has been done at a majority of surveyed airports.
