Red Bank Club improves energy efficiency

By Airman 1st Class Jared Trimarchi | Joint Base Charleston Public Affairs | May 22, 2012

JOINT BASE CHARLESTON S.C. -- The Joint Base Charleston Red Bank Club is in the process of replacing its Heating, Ventilation and Air Conditioning system. The project began April 1, 2012 and is set to be completed by June 27.

The Red Bank Club will be closed, due to the construction of the new system, June 17 through 27.

The older HVAC system, which has been operational since 1969, is being replaced as part of an energy conservation project.

"The HVAC system at the Red Bank Club is in poor condition and in need of replacing to generate energy savings and reduce the cost of running the old system," said Jeff Morgan, Joint Base Charleston Energy Manager. "The HVAC system was in need of continual repairs and wasn't producing the needed amount of air and water to keep the Red Bank Club cool during the summer months and warm during the winter."

Annual savings of more than $184,000 is expected from the new system and a savings of 8,368 million British Thermal Units a year. The base participates in an average of nine energy saving projects a year to reduce the amount of energy used per year by three percent.

"In 1969 energy efficiency was not a top priority like it is today," Morgan said. "The project will pay for itself in less than six years and help lower the emissions let out by the older HVAC system, reducing the base's carbon footprint."

The new system will consist of replacing a boiler, a chiller, two rooftop air conditioning units, a plate heat exchanger and controls for each unit.

"The new chiller will run on an environmentally friendly refrigerant," Morgan said. "The chiller uses a hybridized system, which uses the hot water absorbed from the heat of the building to feed the boiler, which reduces the consumption of natural gas.

"The new electronic controls for the HVAC system enable us to save energy by shutting down when the Club is unoccupied. The older system ran 24 hours a day, seven days a week and the energy wasted from running the system constantly is being omitted."

Gloria Markovci, JB Charleston project manager, said, "Energy savings aside, the new HVAC system will be in place for the summer to maintain a cool and comfortable environment. The older system could not carry the load and people were complaining of the heat. Maintenance cost of keeping the old system running will be [eliminated] by the new system."

The HVAC project is the first of many planned for 2012 at JB Charleston. The Naval Consolidated Brig is next in line to receive a new HVAC system.

"Out of the three percent of energy saving requested a year, two percent comes from investment grade projects such as the new HVAC system and the remaining one percent is generated through the base populace, their awareness, education, cultural change and acceptance of energy policies at Joint Base Charleston," Morgan said.
