62 dBa," says Crawford. "With the addition of the sound baffles, that number dropped to 51 dBa with all the fume hoods operating at full capacity." Suspended from the ceiling in each lab room, noise control baffles further diminish the already-improved sound level. "The noise problem was the starting point for the entire project," says Faircloth. "Our educators and students can now speak using a normal voice." A total noise reduction of 21 dBa made the sound reduction goal of the project a home run. Giving Energy Loss the Runaround Another interesting facet of the systems design is the reworking of the existing hydronic heating system to form a runaround loop between the air handler preheat coil and the air terminal reheat coils. "Air handlers 1 and 2 serve the second floor and air handler 4 serves the fi rst floor," says Hanning. "In the summer, the runaround loop transfers heat from the outside air to the preheat coil, and a Taco inline pump circulates warm water to the reheat coils." Additional savings are achieved by reducing the outside air temperature entering the cooling coils. The run-around loop is connected to the hydronic system through a control valve. The control system monitors space conditions and opens the control valve to increase the loop water temperature as needed. "All we're doing is reclaiming some energy from unused parts," explains Hanning. A Win-Win Situation The M&V report conducted in early 2012 showed an energy savings of $192,000 per year, at current electric and natural gas rates. However, that number isn't indicative of all the savings the project can generate. Because the data period didn't include weather conditions over a hot, humid Savannah summer, it's estimated that an additional $45,000 savings is likely. That would bring the total to $237,000, or a 36 percent reduction in energy cost for the building, 11 percent reduction campus-wide. "In 2001, the emphasis was on labora- tory safety, not energy efficiency," says Faircloth. "I think it's safe to say that both are of the utmost importance now."
