The Military Engineer l No. 66563 retention and reduced maintenance costs. The LEED family of rating systems, including LEED-EB, award points based on ?ve categories: Sustainable Sites; Water Ef?ciency; Energy and At- mosphere; Materials and Resources; and Indoor Air Quality. However, there are distinct differences in LEED-EB that require a very different approach and implementation. The major difference between LEED-EB and other LEED rating systems is that the process is based on building performance. LEED-NC in many ways certi?es a buildings future potential. Many of the credits are awarded based solely on design documents. A good ex- ample is energy performance. Credits are awarded based on a computerized energy model. There is no requirement for a building to perform; the certi?ca- tion instead relies on a professionals assessment. Conversely, LEED-EB requires a building to measure its actual perfor- mance. Facilities must obtain a mini- mum ENERGY STAR rating of 69, which is often one of the rating systems most signi?cant challenges. The ENERGY STAR building rating system measures the energy use of a facility and bench- marks it against a national database of similar building types. Developed by the Environmental Protection Agency, it is a tool for facility managers to assess single and multiple buildings. LEED-EB integrates the ENERGY STAR program into its credits by requiring facilities to track a minimum of 12 months of util- ity data to obtain an ENERGY STAR rating. As such, a building must per- form at a level for a full year in order to obtain a number. This often forces LEED-EB projects to have longer du- rations because upgrades need to be in place throughout the performance measurement period. Stakeholder Involvement For the Navy, Building 1100 was an ideal candidate for a LEED-EB pilot project. The building had been built re- cently with energy ef?ciency in mind. The building also housed energy-con- scious NAVFAC staff who helped ensure that the building operated ef?ciently. Additionally, the buildings outstanding ENERGY STAR score of 95 made costly energy upgrades unnecessary. Another difference is that LEED-EB looks at the way a building is operated and maintained through its policies and procedures. For instance, credits are awarded for policies that include a green cleaning program, sustainable management of the facilitys exterior hardscape and whether durable goods within a building are sustainably pur- chased. Each of these differences presents challenges for facility engineers more familiar with LEED-NC projects. How- ever, one of the largest hurdles of imple- menting LEED-EB projects on a wider scale is the involvement of numerous stakeholders. LEED certi?cation for a new construction project ?ts well into traditional A/E/C contracts. In many ways, agencies have looked to their architect-engineers and contractors to ensure a project obtains a LEED certi- ?cation (at times even contractually). This works because A/E/C projects of- ten are major renovations (de?ned by USGBC as more than half of the ?oor area or replacement of the HVAC sys- tem) and thus fall under LEED-NC. Unlike LEED-NC, a LEED-EB project under most conditions cannot be ac- complished through an outside consul- tant. It requires the direct consent and involvement of agency stakeholders. These stakeholders include the tenant agencies and units, building operations staff, janitorial staff and base engineer- ing, to name a few. The LEED-EB pro- cess can use consultant expertise to help guide certi?cation, develop sustainable polices, conduct commissioning, waste stream audits and ensure the project stays on track. However, the implemen- tation and much of the documentation needs to be done within the agency. Learning New Tricks Testing strategies for implementing LEED-EB was one of the Navys big- gest goals. An integrated project team was developed to collaborate on the Building 1100 project. The team identi- ?ed and capitalized on opportunities to make the buildings processes more ef- ?cient. For example, to encourage lower fuel consumption of the buildings oc- cupants, reserved parking spaces were established for carpools and alterna- tively-fueled vehicles. Within the build- ing, urinals and toilets were replaced with more water-ef?cient models. Ulti- mately, 47 of 85 possible LEED-EB credit points were sought. According to Nathan Finch, Project Manager for Building 1100, the most signi?cant challenge was documen- tation. For example, all buildings use some form of pest management; how- ever, obtaining a LEED-EB credit for a sustainable pest management program requires a written formal policy. While good practice, these polices can be a challenge to draft the ?rst time. Also, with many facilities, pest management programs are handled through various contracts, which can add to the chal- lenge for implementation. The Building 1100 project was com- pleted without any of the team having experience on another LEED-EB project. This learning curve and unfamiliarity proved the value of a pilot project to test Sustainability When Building 1100 at Naval Base Ventura County obtained LEED-EB certi?cation, the U.S. Navy became the ?rst DOD entity to complete what could become a familiar process for the uniformed services and other federal agencies.
