Observations from a Panel at the ACC/AAAE Design and Construction Conference in Denver

by Stephen Barrett

I had the pleasure of participating in a panel on how airports apply unique engineering techniques to take advantage of available resources. I started off the panel discussion by presenting information on ACRP 02-56, Developing the Airport Business Case for Renewable Energy where I described how the research will produce a ranking system which quantifies the economic, self-sustainability, and environmental benefits of renewable energy projects. These benefits include stabilizing long-term electricity costs, investing in a modernized electricity generation and distribution network to ensure reliability and resiliency, and advancing environmental initiatives to open up permitting for future development. Traci Holton, Manager of Design at the Metropolitan Nashville Airport Authority, followed up with a discussion of a variety of examples from Nashville Airport (BNA) including solar planning (which I am helping them with – thanks for the kudos Traci), to asphalt and rock reuse, to converting mulch produced through vegetation management activities into improving site stabilization and minimizing runoff. Traci also described their Geothermal Project which will utilize the constant water temperature from a large on-site quarry for heating and cooling resulting in savings to the airport from avoided natural gas use and potable water previously purchased for boiler make-up and on-site irrigation. The project is currently out-to-bid with a design-build format and requiring a minimum payback period. The last speaker was Dale Stubbs, Associate Vice President for AECOM in Atlanta, who talked about Atlanta Hartsfield-Jackson’s (ATL) Green Acres Recycling Facility that is presently under development. The unique facility will be built, owned and operated by a third party contractor on 39-acres of airport property where all the airport’s waste will be delivered, sorted and managed including the use of compost for growing food that will be sold back to concessionaires. Each of these projects shows how airports can be leaders in developing innovative approaches to areas such as energy consumption and waste management that can produce a financial benefit through the efficient use of available resources.
