Vermont Air National Guard Security Forces Building

Cx Associates provided design, construction and occupancy phase commissioning services to VTANG’s new LEED Gold Certified Security Forces Building. We commissioned mechanical and electrical systems, including ground source heat pumps and solar PV. Our commissioning engineers found several issues during construction phase, such as sensors installed too high and poorly programmed controls sequences. We estimate that the resolution of these issues saved the facility $7,000/yr. in energy and maintenance costs.

Vermont Air National Guard Fire-Crash-Rescue

Cx Associates provided lead commissioning services for a LEED Gold certified renovation and expansion of VTANG’s Fire-Crash-Rescue facility in South Burlington, VT. Our commissioning work with this high-performance building included mechanical and electrical systems, air and water source heat pumps, a geoexchange wellfield, and a 27.63kW PV array on the roof of the station. We developed and coordinated a Measurement and Verification Plan in compliance with LEED-NC 2.2 credit EA C5 to monitor all energy consuming systems through a DDC Base Meter Monitoring System (BMMS).

Middlebury College – President’s House (LEED Platinum)

Cx Associates provided commissioning for the renovation of the historic building that is used as Middlebury College’s president’s residence. The building has been recognized for its energy efficiency, winning Efficiency Vermont’s top award for a major renovation of a commercial building. As a result of our early involvement in the project, we were able to identify an opportunity for the engineer to modify sequences and piping to ensure the heating boiler was not damaged by missing logic. Our follow up on the issue resolved a lack of communication that could have resulted in a voided boiler warranty.
