B-4 Sustainable Airport Construction Practices Appendix B. (Continued). LEED® Research Team Co nsiderations Sustainable Practice LEED ® LEED® Credit Ex ample(s) Economic Env ironmental Operational Social Source (see reference below ) Pre-Construction Policies, Contracts, and Specifications Sustainabilit y Goals Establish a goal for the minimum percentage of local/regional materials and products that are manufactured regionally wi thin a radius of 500 miles. Identify the va lue of local/regional materials so that they can be comp ared wi th of the total va lue of the materials in the task/project. (Manufacturing refers to the fin al assembl y of compo nents into the building product that is furnished and installed by the tradesmen). LEED® MR Credit 5 ORD Regional building materials are more cost effectiv e for projects due to reduced transportation costs. Consider early on in the design process, if possible, sin ce research may be required to determine w hat products can be sourced locally and r ealistically be ex pected to be purchased for the proje ct. Reduces the env ironmental impacts resulting from transportation. It is also importan t to discu ss the source of raw mate rials used to manufacture building products.

May damage buildi ng parts, requiring the purchase of new materials and additional labor costs. Can reduce materials/components that are sent to the landfill and the env ironmental impacts of producing new construction products and materials. Moisture from the air, and some vo latile gases, can condense on cooler sur faces. May damage parts of the building (e.g., mov ing concrete floor slabs, causing carpet and vi ny l flooring to buckle, cracking w indo ws , wa rping w ood doors wa rped, etc.) May reduce delay s associated wi th the ordering/ transportation of ne w materials. Keeping materials pristine may reduce the dur ation of construction projects, minimizing temporar y noise and traffic impacts on the local communi ty . 13

TRB’s Airport Cooperative Research Program (ACRP) Report 42: Sustainable Airport Construction Practices explores a set of best practices, methods, procedures, and materials that if implemented during construction may have a sustainable, positive economic, operational, environmental, or social effect.

The report includes the collection of sustainable airport construction practices in a searchable, filterable spreadsheet format on a CD-ROM, which is packaged with the report.

The CD-ROM included as part of ACRP Report 42 is also available for download from TRB’s website as an ISO image. Links to the ISO image and instructions for burning a CD-ROM from an ISO image are provided below.
