• 100% outside air unit with an energy recovery heat wheel

In 2008, Williams Notaro completed an evaluation for Real Estate Capital Partners to determine if replacing the old HVAC central plant system would result in higher energy efficiency and cost savings in their utility bills. The challenge of this study was determining how to replace a central plant and phase the replacement to maintain building operation. While the evaluation was completed, we determined that the project should be divided into two phases. Phase 1 included the installation of the 100% outside air handling unit to provide code required ventilation and exhaust to the entire building, replacement of the existing cooling tower, installment of redundant cooling towers, and the installation of a condenser water filtration system. This work was successfully completed in 2010.

Phase 2 of the project is currently in the design process and will involve installing condenser and chilled water pumps with variable frequency drives, a high efficiency chiller, a new chilled water coil, retrofitting the existing variable pitch vane-axial fans with variable frequency drives, and enhancing the control system to provide more efficient operation. The construction of this phase will begin in the fourth quarter of 2011 and should be completed around April of 2012.
