Johnson Controls Inc. is working to calibrate more than 525 heating and cooling sensors throughout MHCC classrooms and offices.

According to Dick Byers, facilities manager, the college is ahead of schedule for 13 separate facilities improvement measures.

“I would say we’re 67 percent complete,” said Byers.
Byers is predicting a March 2010 completion for the sensor calibration, which coincides with bringing the new air conditioning system online. “We’re hoping to have (the sensor calibration) completed by next March,” said Byers.

Currently, the cooling tower has been replaced, and the old air conditioning chillers are in the process of being demolished to make way for the new ones.
“The cooling tower has been replaced — that happened last weekend — and the demolition of the chillers is underway,” said Byers.

For the months of July, August and September, MHCC saved $16,000 more than anticipated.

Originally, the guaranteed energy savings from the JCI projects was set at $48,000 but MHCC has actually saved $64,000, Byers said.

According to Larry Holden, site superintendant for JCI’s MHCC projects, once the new wireless thermostats come online MHCC will have the “largest wireless fully integrated heating and air conditioning system in the U.S.”
