EPRI is a very large facility located in Charlotte NC. The design of this system called for three large VAV systems and 10 constant volume systems. With LEED in mind the mechanical systems used many types of controls scenarios from static pressure reset, supply air temperature reset, differential enthalpy economizers and much much more. the controls system selected for this project was Carrier CCN. Carrier was selected for a seamless connection into the customers existing i-Vu plus system. in the course of 10 short months the Carrier system including 50 VAV controllers 3 DX VAV rooftop units, 10 constant volume units, exhaust fans, domestic hot water controls, temperature and humidity monitoring systems where installed and integrated by CSG into the customers existing i-Vu system. When completed custom graphics for equipment and floor plans where loaded matching the style used in the existing building.
