Air Handling Unit Replacement

Dutchess County applied for and was awarded a Federal Energy Efficiency Community Block Grant that was partly used to perform a comprehensive facility audit for each of the county’s 23 buildings. Erdman Anthony provided audit services for 11 of the 23 buildings and worked with a team of engineering and architectural consultants to write a report that the county now uses for master planning and budget projections. The remainder of the grant was used for a capital energy-improvement project.

Erdman Anthony assisted the county in developing a scope of work that would address its immediate operations and maintenance needs, maximize its energy savings, and spend its allotted grant funding effectively without the need for additional funding from local taxpayers.

The scope designed for bid documents included several add-alternates for the air and hydronic systems, including air handling unit replacements, rebalancing of perimeter radiation systems, automating chilled water and heating hot water operations, and reconfiguring ductwork and building management system upgrades. The final construction scope was to replace each floor multizone air handling unit with three single zone units and to provide a building management system front-end that controls the new equipment and optimizes performance to save as much energy as possible.

Much of the construction was performed on weekends and evenings, so the building remained occupied without disruption to the county employees.

Erdman Anthony provided construction administration services and provided construction management duties so that the county could execute the multiple prime contracts (mechanical, electrical, and asbestos abatement) without the additional cost of a general contractor or construction manager.
