Powers was called to address poor air distribution at one of Pratt & Whitney's manufacturing facilities. We found a solution that would help redistribute the air and also maximize the comfort and efficiency of the HVAC system.
This project was a design build solution by Powers that transformed a poorly operating HVAC system into an efficient system that also increased the occupant comfort level. The DX AHU was leaking and inefficient. The VAV boxes were poorly zoned and not controlling properly due to outdated pneumatics and lack of volume control.
An old air cooled chiller had run its course in the Choctaw Building occupied by the Clinton School for Public Service and needed to be replaced. Meanwhile, 10-year-old inefficient Trane chillers were costing their neighbor next door, the William J. Clinton Presidential Library, a ton of money. Together they needed a solution that could provide chilled water for both facilities more efficiently as well as a better Building Automation and Controls System that could operate the chiller plant along with the entire facility.
The Villa Maria Retirement Home had an aging two pipe fan coil system that was failing and needed to upgrade the plant and provide new chilled water and hot water riser throughout the facility. An Engineer called Powers looking for an affordable solution to the retirement home's problems.
The E.L. Bolton State Office Building in Mississippi was in the middle of construction on their first floor when it seemed they had missed something. As part of the project they were replacing some ductwork and upgrading the controls on the air handler units. When the spaces were not maintaining temperature, they asked us to look at the problem.
Due to rising energy costs, HVAC systems must perform more efficiently. With 25-year-old inefficient chillers and progressively higher costs to maintain the chillers, it became apparent to the management of the Simmons Tower that it was time to replace them.
