In 2019, Cx Associates assisted VTARNG with an energy assessment of three facilities: Regional Training Institute, the Jericho Readiness Center, and the Green Mountain Armory. This work utilized Efficiency Vermont’s Retrocommissioning (RCx) program. Using ASHRAE Level I Energy Audits, we assessed the energy consumption, water consumption, and mechanical and electrical system infrastructure to identify low-cost operating and controls measures for inclusion in VTARNG’s developing Installation Energy and Water Plans (IEWP). We recommended a list of infrastructure investments and capital improvements vital to meeting the IEWP mission goals regarding effective operation, mitigation of risks, lowering operating costs, and reducing energy and water consumption. For example, the measures identified for the Jericho Readiness Center would save VTARNG approximately 45,713 kW/yr.
