VGLZ 232027: Repair HVAC Bldg 560

The 127 Wing (WG) requires energy efficient and adequate Heating,
Ventilation, and Air Conditioning (HVAC) equipment and controls to support habitable spaces requiring proper
environmental controls for Building 560 (B560), Radar Approach Control Center and Air Traffic Control
Tower, to conduct aircraft operations. The period of performance is 365 calendar days after receipt of Notice to
Proceed. contain R22 refrigerant, which is difficult to maintain, and the preventative maintenance material
costs are high. The boilers and pumps in Building 560 are approximately 22 years old and approaching the end
of life. The hot water circulation pumps, associated with the boilers, and valves are also in poor condition. A
HVAC system assessment was conducted in 2022 and was provided a 46 average component index in
BUILDER with less than 1 year of remaining service life. This project takes necessary steps to comply with
provisions of the mandates and is a follow-on to the Energy Conservation Opportunity (ECO) implementation
as recommended by the latest energy audit. Replacement of older HVAC equipment and DDC with newer
energy efficient units will help meet the mandates for energy conservation. All units being replaced currently
contain refrigerant R-22 which has been mandated to be removed and replaced with units using R-410A, as
applicable, in accordance with sustainability and environmental policies. Any R 22 refrigerant will be captured
and reclaimed at the installation.
