The heating system is a twin boiler and circulation pump system providing a redundant system with one system in operation and the other system on standby. The building cooling is controlled by Variable Air Volume (VAV) boxes designed to supply a constant 60 F degree air to each Zone. The system was modernized and upgraded in 2011. The VAV boxes are supplied by two large roof top mounted packaged heat / cool units, manufactured locally by Engineered Air. This type of system provides excellent and flexible zoning for the space and allows for 100% fresh air intake keeping offices at the perfect temperature with excellent air quality.
