Evaluating Systems to Improve Energy Efficiency and Resiliency for the Department of Defense

GTI initiatives aim to help the Department of Defense (DOD) reduce their need for facility energy, while also enhancing onsite energy reliability and resilience by developing and deploying advanced cost-effective and efficient energy solutions for buildings, onsite generation, and resilience.

 

GTI is evaluating a comprehensive slate of emerging technologies at Illinois Army National Guard facilities and the U.S. Army Engineer Research and Development Center (ERDC) in Mississippi for their ability to cost-effectively reduce energy use and improve energy resilience.

These multi-phase RD&D projects are evaluating technologies using higher efficiency cycles, improved controls, energy recovery, and other enhancements for their ability to cost-effectively reduce energy use and improve energy resilience. The equipment includes combined heat and power or distributed power generation, hybrid non-condensing/condensing boilers, destratification fans, and similar hardware.

Demonstrating Natural Gas and Electric Heat Pump Systems in a Cold Climate

VRF Site Equipment 285x364

A side-by-side assessment of a gas engine heat pump (GHP) and electric cold climate heat pump for heating/cooling compared to an existing conventional HVAC system has been completed at Naval Station Great Lakes.

Variable refrigerant flow (VRF) heat pump systems provide space conditioning for multi-zone commercial buildings. The demonstration included a measured field performance evaluation as well as enhancement of Energy Plus models for both gas and electric variable refrigerant flow (VRF) heat pump systems which provide space conditioning for multi-zone commercial buildings. Both VRF systems demonstrated improved comfort along with energy savings, reduced peak electric demand, and lower lifecycle costs compared to the baseline system.

Both VRF systems reduced primary energy use by about 57% and lowered full-fuel-cycle GHG emissions by over 50% compared to the baseline.

Energy and Water Efficiency Improvements for Dishrooms in Military Dining Facilities

Orig DishMachine 425x283

At the U.S. Army Garrison Presidio in Monterey, California, three dishroom technologies—waste water heat recovery, an advanced ventilation system, and a low water usage warewasher—were integrated to demonstrate and quantify energy and water savings.

The demonstration of this high-efficiency commercial food service dish machine produced noteworthy results including 51% gas savings, 41% electricity savings, and 81% water savings.

A Best Practices Guide and webinar were developed to assist energy managers, consultants, and commercial foodservice contractors at DOD locations in understanding the benefits of these dishroom technologies.
