62The Military Engineer l May-June l 2010 I n 2006, the staff of the Naval Facilities Engineering Command (NAVFAC) Engineering Service Center (ESC) decided to examine the applicability and cost-effectiveness of the U.S. Green Building Councils (USGBC) Leadership in Energy and Environmental Design for Existing Buildings (LEED-EB) rating system. As part of a leadership develop- ment initiative, Joe Connett, Director of the ESC Facilities Systems Division, drafted a proposal to implement sus- tainable strategies to Building 1100 at Naval Base Ventura County, Calif., the ESC headquarters facility. Navy leader- ship agreed, and ESC was challenged to apply the LEED-EB rating system and prove Conetts proposal. Shortly after the Facilities Systems Division took on the challenge, the U.S. Navy issued an Engineering & Construc- tion Bulletin requiring that all projects be registered with USGBC and LEED submittal documentation certi?ed by USGBC to meet the LEED Silver rating. Many federal agencies, including the U.S. Army and U.S. Air Force, have sim- ilar requirements. Almost exclusively, projects have utilized the LEED for New Construction (LEED-NC) rating system in meeting these requirements. Over the past few years, LEED-NC has become common practice for new and major renovations of Department of Defense and service facilities. Re- cent presidential executive orders and congressional oversight have placed an emphasis on reducing the energy usage of each service. Executive Order 13423—Strengthening Federal Envi- ronmental, Energy, and Transportation Management, issued in 2007, requires that 15 percent of buildings, measured by square footage, meet de?ned sus- tainable guidelines. In meeting this goal, updating existing buildings as new construction will not be suf?cient. Executive Order 13514—Federal Leadership In Environmental, Energy, and Economic Performance, issued in October 2009, requires agencies to meet greenhouse gas reduction targets, once again placing a large importance on services existing buildings. To meet these mandates, many federal agencies have begun considering LEED-EB certi- ?cation, and in doing so have encoun- tered challenges inherent in applying LEED-EB using the same approach as LEED-NC. Defining LEED-EB The LEED-EB rating system is de- signed to focus speci?cally on the op- erations and maintenance of existing buildings. The end state of the certi?- cation process is reduced energy and water usage, reduced waste, increased sustainable product usage, ef?ciently- managed building operations, im- proved indoor air quality and increased low-impact material usage. The ben- e?ts of a LEED-EB certi?cation include lower utility bills, lower lifecycle costs, more productive employees, increased By Luke J.
