National Deep Energy Retrofit Program
In 2012 General Services Administration (GSA) issued a notice of opportunity to the 16 energy service companies (ESCOs) associated with the Department of Energy’s energy savings performance contracting (ESPC) indefinite-delivery indefinite-quantity contract, including potential projects at 30 GSA-owned buildings covering a total area of 16.9 million square feet in 29 states and the U.S. Virgin Islands. GSA ultimately awarded ten ESPC task orders with a total value of $172 million distributed among seven ESCOs. The team sent a strong message that a greater level of energy savings was desired, leading to the incorporation of some typically under-used, but lucrative, energy conservation measures. The program also established a central Project Management Office to standardize the ESPC review and award process, allowing for a more consistent and higher level of expertise across the program. The team was able to achieve a significant reduction in project cycle time, awarding the ten task orders in an average of 15.9 months, compared to 20.9 months for typical projects. The projects also achieved an average energy savings of more than 38 percent, which is about double the average achieved by other recently awarded ESPC projects at 19 percent savings.energy, and has already led the way for similar systems at other VA facilities.

Over the past six years alone, the Tennessee Valley Authority has realized a cumulative utility cost reduction of $13.7 million saved through the implementation of energy and water conservation projects. As of FY 2013 the agency achieved a 24.4% reduction in energy intensity compared to FY 2003, a 21.7% reduction in potable water intensity compared to FY 2007, and a 13.9% reduction in target subject greenhouse gas emissions compared to FY 2008.
U.S. Air Force
Royal Air Force, Mildenhall, UK
Steve Perry’s efforts at Royal Air Force Mildenhall to develop the Air Force’s first installation-based “holistic energy plan” resulted in combined facility energy, aviation, and vehicle energy cost savings of $1.8 million in FY 2013. Mr. Perry incorporated a holistic strategy into the installation’s FY 2013 to 2014 Energy Action Month plans, which delivered more than 50 cross-functional activities in FY 2013 alone. More than 20,000 personnel and family members helped to save $500,000 through their participation. Further, the program empowered high energy consumers and the more than 400 onsite facility managers to take ownership of future utility reductions. Facility managers were provided tools to benchmark usage, trained to find low cost improvements, and incentivized with a new quarterly award program. Through progressive teamwork, and by tearing down cultural barriers, Mr. Perry moved the traditional civil engineering-centric approach to a wider audience, providing greater visibility to all energy and water commodities for aircraft, vehicles and facilities. His initiative was praised by the Deputy Assistant Secretary of the Air Force (Energy), and is now the benchmark for the U.S. Air Forces Europe Major Command.

Naval Air Station Oceana Energy Program
Virginia Beach, Virginia
During FY 2013, Naval Air Station Oceana energy program initiatives saved 18 billion Btu and 39 million gallons of water from the prior year. Naval Air Station Oceana’s energy program sought to incorporate strategies that would limit financial stress on an already tight budget. They focused on energy awareness, new technologies to improve existing systems, increasing equipment performance, and identifying sustainable building infrastructure solutions. The team implemented a variety of projects including retro commissioning, installation of ground source heat pumps, and lighting upgrades. Naval Air Station Oceana also created the concept of Distributed Energy Teams as a key component of its awareness program to encourage a natural, friendly competitive environment that will install energy conscious behaviors. The teams will infuse interesting, informative, and diversified activities into the program to maintain command involvement and interest, while also remaining self-administering and self-sustaining. As a result of these and other program efforts, as of FY 2013 Naval Air Station Oceana reduced its energy intensity by 52% and water intensity by 24% over their respective baselines.
Naval District Washington (NDW)
Naval Facilities Engineering Command Washington (NAVFAC Washington)
In 2013 the Naval District Washington built the foundation for a comprehensive energy program that reduced energy intensity by nearly 19% and water intensity by 13% from the respective baselines across the region’s six installations. The program focuses on five energy pillars: energy culture, energy information, energy efficiency, renewable energy/alternative fuels, and energy security. Initiatives implemented in FY 2013 included establishing five teams to enhance energy leadership across the region. The teams focus on optimizing retro-commissioning projects; identifying potential renewable energy opportunities; collecting and analyzing data on fuel consumption; installing advanced metering and deploying smart grids that enable technologies to monitor, control, and respond to building and utility management systems; and coordinating system monitoring, administration and dispatch of staff. The program created 50 megawatts of renewable energy opportunity and brought the total of advanced metering infrastructure to 99% installed with 37% actively connected. The Naval District Washington’s comprehensive program forms the basis of its energy policy and fundamentally empowers all employees to use energy resources efficiently all the time.

Alternative Fuel Vehicle Management Program
North Las Vegas, Nevada
In FY 2013 the Nevada National Security Site’s fuel Lockout Program resulted in the increased use of renewable fuel by 35.3% and a decrease in the use of petroleum based fuels by 18.6% compared to FY 2012. Program results were improved in FY 2013 due to the installation of a second E85 infrastructure to enable the availability of renewable fuels (E85 and B20) at both of the site’s fueling locations. The E85 Lockout Program is a modification to the fuel management system that involved reprogramming the system to identify and prevent alternative fuel vehicles from getting non-renewable fuel from the site’s fueling stations. The reprogramming was accomplished by the Fleet, Fuel, and Equipment Service Renewable Fuel Program Team after the manufacturer of the system was unable to assist. The E85 Lockout Program was first instituted at the Nevada National Security Site in FY 2009 at the first service station, and then again in FY 2013 at the second service station. In total, implementation of the program at both service stations has increased consumption of renewable fuel by approximately 195% when compared to the FY 2005 baseline.

Visualizing Water Savings at Mountain Park Project
Bureau of Reclamation, Oklahoma-Texas Area Office
Oklahoma City, Oklahoma
In FY 2013, efforts of the Bureau of Reclamation’s Oklahoma–Texas Area Office to conserve water in the region resulted in savings of 1.14 billion gallons—a 37% reduction from the prior year. In 2009, the office designed and created a drought forecast model to verify and update Tom Steed Reservoir yields. On a monthly basis, the model simulates the lake volume and elevation based on historical inflow and predicted losses and releases from the reservoir. In light of growing concerns about reservoir depletion during ongoing extreme drought conditions, in FY 2013 Oklahoma–Texas Area Office management identified the opportunity to provide drought assistance to their operating partner, the Mountain Park Master Conservancy District. Use of the model resulted in increased understanding and awareness of the impacts of the ongoing drought, and led to the implementation of significant and often mandatory water conservation measures throughout the region. Along with the tremendous water savings, ancillary benefits included cost energy savings of about $40,000 from reduced pumping requirements, about $10,000 in operation and maintenance savings and avoided water treatment costs, and improved recreation and fish and wildlife conditions due to higher reservoir levels.

Kansas City Air Route Traffic Control Center
In FY 2013 Jeff Hernbloom partnered with the local utility to implement and manage a new initiative, the Cooling Tower Evaporation Credit Program, which resulted in more than $18,500 in savings in one year for the Kansas City Air Route Traffic Control Center. After investigating and discovering his facility was drastically overpaying for water treatment, Mr. Hernbloom convinced management to invest $1,500 for a one-time purchase of metering equipment to measure the precise amount of water being expelled from the cooling towers into the sewer discharge system. Previously, sewage charges were based on only the measured input water to the cooling towers. After subtracting the thousands of gallons of water—70% or more of the supply—that evaporate monthly as part of the cooling process, utility charges are now drastically reduced and more accurate data is provided to personnel to better monitor and tune the operating efficiency of the equipment. Additional benefits are realized from optimizing energy and chemical loads. Mr. Hernbloom has already started consulting with other facilities to implement the program throughout the Federal Aviation Administration, with savings of nearly $400,000 in water utility costs expected annually across 25 Air Traffic Control Centers.

Public Buildings Service, Office of Facilities Management and Services Programs, Energy Division
As landlord for the civilian federal government, GSA’s Public Buildings Service is able to initiate programs with the potential to generate considerable energy savings. This includes three related initiatives—advanced metering, Rapid Building Energy Assessments, and the Energy Usage and Analysis System—that resulted in energy intensity reductions of 9.3% and savings of $27.3 million in FY 2013 as compared to FY 2011. The program’s advanced metering initiative has far exceeded legislated requirements, with the number of buildings currently metered or slated for meter installation accounting for about 91% of energy consumed by all GSA facilities. Rapid Building Energy Assessments is a virtual modeling approach that facilitates large scale building energy performance analysis, reducing the need for costly onsite audits. After a successful pilot on 25 buildings, the program is now moving forward with 200 more. Finally, the program upgraded its Energy Usage and Analysis System, responsible for tracking utility use and cost data in all GSA-managed buildings nationwide, for easier viewing of the latest data by individual building, service center, or region. The combined use of these tools provides a focused effort to collect, analyze, and manage the right data, which has led to more informed energy decision-making across GSA’s building portfolio.

Conversion for Advanced Power and Thermal Research Lab, Building 23
Wright-Patterson Air Force Base, Ohio
In FY 2013 a team of architects and engineers from Wright-Patterson’s 88 Air Base Wing Civil Engineering Division successfully salvaged and renovated an underused, historic 53,000 square foot hangar built in 1934, increasing usable laboratory space by 60% while reducing water use by 45% and energy use by about 30%. The new energy efficient building allowed the Air Force Research Laboratory’s Power Control Division, formerly located in multiple locations, to consolidate. An improved thermal envelope with spray foam insulation, stringent HVAC requirements, high-efficiency glazing, reduced exterior lighting, and occupancy sensors are projected to reduce energy use by 9.8 billion Btu and energy costs by more than $141,000 per year. Water savings are estimated at 62,000 gallons per year. The building design surpassed the required Leadership in Energy & Environmental Design Silver criteria to achieve Wright-Patterson’s first Gold Certification. Further, the renovation/consolidation project allowed for the demolition of building 450, reducing Wright-Patterson’s footprint by 148,300 square feet and saving an additional 8.7 billion Btu annually.

Joint Base Elmendorf Richardson Energy Team
Landfill Gas Waste-to-Energy Initiative
Joint Base Elmendorf, Richardson, Alaska
In FY 2013, Joint Base Elmendorf Richardson’s newly constructed landfill gas waste-to-energy plant generated 44,000 megawatt-hours of renewable energy, saving the Air Force almost $1.8 million in energy costs. For many years the Anchorage Municipal Solid Waste Landfill, located adjacent to Joint Base Elmendorf Richardson in Anchorage, Alaska, collected and burned landfill gas. To increase the installation’s renewable energy use and improve energy security, the team partnered with the Municipality of Anchorage and Doyon Utilities to convert the landfill gas into usable energy for the base. This is first landfill gas-to-energy facility constructed in Alaska, and includes an electric power generation plant, a landfill gas processing module and pipeline, an electric tie to the base’s D-Street substation, and a natural gas pipeline. The partner utility operates and maintains the plant through a utility energy services contract with the base. The anticipated lifecycle renewable energy production is approximately 3,000,000 megawatt-hours over 46 years, for $70 million in savings. Operation of the facility resulted in a reduction of 7,800 tons of greenhouse gas emissions in FY 2013. With additional generators due to come online in 2016, the facility will avoid nearly 14,000 tons of greenhouse gases per year.

Surfing Aircraft Vortices for Energy ($AVE)
Scott Air Force Base, Illinois/Wright-Patterson Air Force Base, Ohio
In July 2013, two C-17 aircraft successfully demonstrated the Surfing Aircraft Vortices for Energy ($AVE) concept on an operational mission, achieving a direct savings of $7,500 in fuel costs. The $AVE concept uses formation flight principles derived from flocks of migrating birds, with trail aircraft harvesting energy from the upward velocity (or upwash) of the formation leader. In 2007, the Defense Advanced Research Projects Agency initiated a study with Boeing to investigate what would be required to apply $AVE to the C-17, the largest consumer of aviation fuel in the U.S. military. Boeing predicted optimum formation positions and developed software, enabling $AVE operations with existing C-17 hardware. Following software installation, the successful demonstration resulted in the trail aircraft reducing fuel use by 10,800 pounds. Air Mobility Command then commissioned $AVE as an advanced technology demonstration; Air Force Research Laboratory identified potential $AVE candidate missions and found more than $10 million could be saved each year in the C-17 fleet alone with minor alterations to mission parameters. By applying the $AVE concept fleet-wide across the Air Force, possible fuel savings are estimated at greater than $50 million annually.

Graywater Tank and Distribution System
Hurlburt Field, Florida
In FY 2013 Hurlburt Field Air Force Base modified its water reuse system to improve capacity, resulting in savings of 13 million gallons of water in only four months—a 9% reduction from the previous year. The $4.9 million project added more than 40,000 linear feet of piping and a 500,000 gallon storage tank to the existing distribution system, increasing the amount of water available for reuse. Previously the system reuse capacity was limited to only 10,000 gallons per day, with 98% of the wastewater treatment plant effluent being discharged to permitted wetlands after being treated and de-chlorinated. The new system maximizes reuse of wastewater treatment effluent, decreasing the stress on local drinking water supplies, promoting the recharge of the groundwater within the local aquifers, and reducing the possibility of saltwater intrusion within the area. Hurlburt now uses the treated reuse water for irrigation, aircraft and vehicle washracks, fire training, and cooling towers. In addition, the base can provide up to 200,000 gallons per day of excess water to the local community for reuse. Overall the program has reduced Hurlburt Field’s water intensity by almost 20% from the 2007 baseline.

Davis-Monthan Air Force Base Energy Program
Davis-Monthan Air Force Base, Arizona
Davis-Monthan Air Force Base’s Energy Team worked with local utilities, military construction design teams, other Air Force agencies, and the Department of Energy to implement projects and programs that saved 11.6 billion Btu and $235,000 in FY 2013 from the prior year. Central plant base cooling projects included installation of energy efficient chillers in a new central plant with a chilled water distribution loop and a plate and frame heat exchanger to cool both new and older facilities. The team also completed a four-phase project that upgraded all large facility boilers base-wide. A second base-wide project changed out 675 high-pressure sodium lighting fixtures to T-5HO fluorescent lights. The installation of 580 light-emitting diode taxiway lights will result in a one-year payback and significant maintenance savings. Retro-commissioning was completed on more than 200,000 square feet during FY 2013, including two high security facilities. All newly constructed buildings on the base are designed to Leadership in Energy and Environmental Design Silver standards or better. The team works with the local utility to receive the maximum return of rebate surcharges, with more than $50,000 received to date and a forecasted total of more than $160,000 through 2015.
Fort Meade Synchronous Reserve Program with American Water, Viridity Energy and Sain Engineering Associates, Inc.
Fort Meade, Maryland
In FY 2013 the U.S. Army Fort Meade worked with American Water, Viridity Energy, and Sain Engineering Associates to implement a project to respond to electric grid frequency fluctuations for the Fort’s water filtration plant, saving about 2.3 billion Btu and $75,000 in utility rebates annually. This was the first successful program at a large water filtration plant to use a new Source Control and Data Acquisition or SCADA system to optimally cycle the pump motors during grid frequency events without affecting water operations. Meter pulse data kits and cable runs to the SCADA were installed, allowing the team to check high horsepower water pump motors and associated electric meters in the field to retrieve real time interval data needed for demand response participation. When the system operator is contacted by the utility, some or all of the pumps can be cycled off as needed. System operators prepare for such events by choosing optimal times for pumping during off peak periods, with large water tanks pumped full overnight in preparation for daytime demand. This project improves security, reducing the chances of a brownout while also reducing peak load and demand charges. The team is now working to expand the program to the wastewater side of operations for further savings.
Naval Air Weapons Station China Lake
Navy's Largest Power Purchase Agreement Solar Plant
China Lake, California
In FY 2013, Naval Air Station Weapons Station China Lake completed construction of a 13.78 megawatt solar photovoltaic (PV) system—the largest solar plant in the Navy and the first installed on a Department of Defense installation—using a 20-year solar power purchase agreement. The new PV plant produces 30,000 megawatt-hours annually, providing 30% of Naval Air Weapons Station China Lake's annual energy consumption. Under the power purchase agreement, the site will purchase $80 to 100 million worth of energy at the negotiated price during the next 20 years, avoiding about $13 million in energy costs over the contract period. To make this project possible, extraordinary effort went into market research, technical analysis, industry partnership, preparation of complicated acquisition documentation, and navigation of complicated regulations and incentives. During 18 months of discussions, the team successfully negotiated the terms and conditions that satisfied both government and private financing requirements. Use of the power purchase agreement as a financing model has been growing within the Navy, and with the knowledge gained from this project, the agency plans to further streamline the approval process to pave the way for additional new agreements.

Camp Lemonnier Energy Generation Reconfiguration Savings
Camp Lemonnier, Djibouti
In FY 2013, the energy team at Camp Lemonnier, Djibouti implemented an air conditioning improvement project that saves 61 billion Btu and $2 million annually. The Camp is located in one of the hottest inhabited places in the world, with temperatures of between 77 to 111 degrees Fahrenheit year-round and humid, salty, dusty air. In this harsh environment it is difficult to keep equipment operating at maximum efficiency. The site generates all its own power from diesel generators, and the team recognized that generating power more efficiently would make a significant, immediate impact on energy efficiency. They developed a project to reconfigure Lemonnier’s energy production by eliminating the least efficient generators, consolidating loads, connecting the two power plants to remove the need for excess reserves and improve capacity, and operating only the most efficient generators when loads permitted. Additionally, 900 air conditioning units were replaced with higher efficiency units. Together these projects resulted in a 9% energy consumption reduction from the prior year, with a project payback of only 1.5 to 2 years.

U.S. Geological Survey Great Lakes Science Center
Wet Laboratory Upgrade
Ann Arbor, Michigan
The U.S. Geological Survey’s Great Lakes Science Center completed a major wet lab upgrade in FY 2013 that will save $9,000 in annual storm water discharge costs and decrease water use by about 52.6 million gallons per year. The upgrade replaced a once-through well water system with a re-circulating city water system, dramatically increasing capacity and efficiency and eliminating the constant flow of well water. Prior to the upgrade, the wet lab was becoming increasingly difficult to operate due to plugged water lines and failure of equipment already at or near the end of its useful life. The design team and scientists worked together on a cost effective, holistic approach, developing a plan that combined several projects on the maintenance and construction backlog and replaced the entire process water system, including peripheral components. The re-circulating system also reduces chiller operation, and the change to city water and use of polyvinyl chloride plastic piping dramatically improves water flow, which in turn reduces pumping energy. These improvements will save about 1.2 billion Btu of energy per year.

In FY 2013 the U.S. Fish and Wildlife Service completed a high performance Leadership in Energy and Environmental Design Silver-rated, 11,759 square foot Headquarters and Visitor Center at the Upper Mississippi River National Wildlife and Fish Refuge. A 74.86-ton ground source heat pump, three solar hot water collectors, and a 35.88 kilowatt grid-tied solar PV array generate 313 million Btu of renewable energy that will save at least $4,700 annually. Energy efficiency strategies throughout the all-electric building include: passive solar energy architecture; thermal mass; superinsulation; a cool roof; abundant daylighting; low-e glazed operable windows; energy-efficient fluorescent and light-emitting diode lighting; and occupancy sensors and timers. Approximately 46% of the total building materials—gypsum board, acoustical ceiling tiles, carpet, ceramic tile, restroom partitions, and the steel roof—were manufactured using recycled materials. Low flow water fixtures conserve almost 30,000 gallons of potable water annually, along with a 3,000 gallon rainwater harvesting and containment system that provides water for flushing toilets and urinals. Located in scenic Brice Prairie at the gateway to the Refuge, the attractive facility teaches more than 30,000 visitors a year about the benefits of sustainability.

Wichita U.S. Courthouse Energy Savings and Systems Retuning Project
GSA Region 6 achieved a 20% energy intensity reduction at the U.S. Courthouse in Wichita, Kansas in FY 2013 from the prior year. Several high-impact energy-saving changes were completed at the 80 year old facility through a 2010 American Recovery and Reinvestment Act project, including an advanced metering installation and upgrades to air handlers, boilers, chillers and building controls, but the GSA Region 6 team pressed for further energy savings. The team initiated a targeted Energy Efficiency Expert Evaluation, or E4, retuning project; implemented building staff-initiated energy management practices; and engaged contractors and tenants. The retuning project included a process through which specific no- and low-cost adjustments to building systems were identified and executed. Together the projects have an expected payback of two years, and resulted in more than $21,000 in energy cost savings compared to FY 2012. These achievements were possible due to partnerships with the Pacific Northwest National Laboratory, operation and maintenance and janitorial contractors, and the courthouse tenants, as well as the planning and persistence of the Wichita Courthouse building manager, the hard work of the operations and maintenance staff, and the dedication of the GSA Region 6 energy team.

Hart-Dole-Inouye Federal Center Water Saving Projects
Battle Creek, Michigan
In FY 2013, GSA’s Hart-Dole-Inouye Federal Center saved about 10 million gallons of water—a greater than 50% reduction— by implementing $36,000 in conservation projects. First the team repurposed existing building infrastructure to send rainwater through drains on two roofs to an abandoned 125,000 gallon cistern. Once treated and filtered, water from the cistern is used for both cooling tower make-up water and manual irrigation. The team also installed a weather station that sends data to the building automation system controlling irrigation. Sophisticated programming logic was added to the building automation system based on the data provided from the weather station, thus allowing the calculated evapotranspiration rate to determine whether or not to irrigate instead of a simple time clock. Further, a survey of the irrigation lines resulted in the closure of several lines found to be unnecessary to serve the Federal Center’s current irrigation needs. It is estimated that together the projects saved about $45,000 in costs in the first year of operation, resulting in a payback of less than one year.
Thomas E. Creek VA Medical Center
Integrating Solar Power with Thermal Storage
In 2013 the Amarillo Veterans Affairs (VA) Health Care System constructed a 2.28 megawatt PV covered parking project at the Thomas E. Creek VA Medical Center that provides about 30% of the center’s electricity to save $245,000 annually. Keeping vehicles cooler during summer and protecting them from rain, snow, and hail, the innovative PV system is the first in the VA used in conjunction with an ice thermal storage system, which was designed to shift the medical center’s air conditioning load from day to night. Integrating the PV with thermal storage load shifting further reduces daytime energy needs. When PV and thermal storage are functioning at their peak, some electricity is even sent back to the grid, which pays for electricity that VA uses at other times. This synergy of solar PV and thermal storage has distinguished the medical center as VA’s leader in minimizing daytime electricity demand. It has helped set the standard for integrating different types of sustainable
