The Department of Defense’s Environmental Security Technology Certification Program (ESTCP) has announced 22 new projects to demonstrate emerging energy and water technologies on military installations through its Installation Energy Test Bed initiative. This initiative plays a key role in testing, evaluating, and scaling up innovative new energy technologies to improve the department’s energy security and reduce its facility energy costs. A list of the selected projects may be found below.
The Department has 300,000 buildings on its installations and spends nearly $4 billion a year on the energy needed to operate them. Demonstrations generate the cost and performance data needed to validate promising technologies, allowing them to be fielded and commercialized more rapidly. These technologies will enable DoD’s installations to operate using less energy, and they will improve energy security by allowing installations to maintain critical activities even if the commercial electric grid is disrupted.
The 22 projects were competitively selected from the 468 proposals submitted by private firms, universities, and federal organizations. The fiscal 2013 awards cover six areas: smart secure integrated installation energy management; cost effective on-site distributed generation; advanced component technologies to improve building energy efficiency; advanced building energy management and control; tools and processes for decision-making associated with energy use and management; and advanced water management and controls for DoD buildings.

This innovative design can be retrofitted into existing servers and data centers with a potential payback of less than one year. At scale and if proven feasible through the Test Bed demonstration, RackCDU could potentially save DoD $200M per year in energy costs.
Belkin International, Inc.: Real-Time Itemized Electricity Consumption Intelligence for DoD Bases
: Camp Pendleton, CA; MCAS Miramar, CA
: Belkin’s electricity itemization technology uses a sensor installed at a building’s circuit breaker or meter panel. The sensor detects real-time current changes as well as broadband noise created by devices as they switch on or off or otherwise change state. The power characteristics and noise from each type of device have a unique signature that results from the device’s electrical circuit design. The Belkin sensor captures this signature and uses machine-learning algorithms to analyze it and identify each use of each device and the amount of energy consumed. The system can create reports, such as a consumption report similar to a credit card or telephone bill, and/or make data available to other systems for analysis or control.

Terrajoule Corporation: Demonstration of the Zero Emission Distributed Generation and Storage System
: San Luis Obispo, CA
: Terrajoule technology eliminates the fundamental barrier to the broad adoption of clean solar power as a distributed energy system: the cost of storing energy where it is generated so that the system is not vulnerable to the disruption of the electrical grid. This project will demonstrate the Terrajoule Distributed Generation and Storage (DGS) system - a cost competitive (<$0.09/kWh), zero emission alternative to traditional distributed generation systems. The DGS utilizes curved mirrors to collect sunlight for steam production which is used to make power, and is stored in the compact form of superheated water so that power can be generated later, even when the sun is not shining, providing 24 hour power.

Brookhaven National Laboratory: Demonstration of a High-Efficiency Evaporative Cooler for Improved Energy Efficiency in DoD Data Centers
: Port Hueneme, CA
: This project involves installation of a state-of-the-art indirect evaporative cooler called the Oasis Polymer Fluid Cooler (Oasis PFC) system at a DoD data center. The system is unique in that it can operate in both wet and dry modes, as ambient conditions permit, to maximize annual energy and water savings. The innovative design of this system minimizes the utilization of water as compared to conventional evaporative cooling devices. The use of a polymer – rather than metal – heat exchanger minimizes issues with fouling and water contamination, which simplifies water treatment and minimizes maintenance. The Oasis PFC is expected to reduce data center energy costs by 50%.
Lawrence Berkeley National Laboratory: Immersion Cooling of Electronics in DoD Installations
: Naval Research Laboratory, Washington DC
: Open bath immersion cooling efficiently cools the highest heat density electronics in data centers without the need for compressor based cooling systems. In two‐phase immersion cooling, live electronics are immersed in a dielectric liquid that changes phase on the heat generating components thereby cooling them. The vapor generated is condensed within the system through a condensing unit and the heat is transferred outside to a dry cooler through a water loop. The condensed dielectric fluid passively flows back to the immersion tank to repeat the cycle. Because this system operates well using high temperature coolant, dry coolers can be used for heat rejection to the atmosphere thereby eliminating water use anywhere in the world. This very simple system has the potential to provide the most efficient cooling for energy intensive electronics with reduced capital cost and reduced operating expense.

U.S. Army ERDC-CERL: High Efficiency Dehumidification System
: Fort Bragg, NC; West Point, NY; Tinker AFB, OK
: The High Efficiency Dehumidification System (HEDS) being demonstrated uses the low quality heat generated during cooling and dehumidification processes to provide required reheat energy which lowers the relative humidity of the air being supplied to the occupied spaces. This process reduces the potential for biological growth to occur and it reduces the cooling load on the chiller plant, thus eliminating the need for supplemental reheat and substantially reducing heating plant energy consumption.
U.S. Army ERDC-CERL: ROOFER Energy Performance Assessment and Courses of Action Analyses
: Fort Riley, KS; McConnell AFB, KS; Jacksonville NAS, FL
: ROOFER is a decision-support tool that provides a systematic, automated approach to managing large inventories of building roofs. It is, by regulation, the roof asset management system required to be used by Army installations; and the other services are actively pursuing integration of ROOFER into their business process. However, ROOFER does not currently include consideration of energy performance and impact of energy technologies within its analyses. This project will provide that capability. Having access to the ROOFER database of inventory and inspection information provides an excellent opportunity for facility managers to assess roof energy performance and evaluate energy related and sustainability technologies.
