The steady growth of the company caused it to expand far beyond the adequacies of Dr. Bugbee's garage and, in 2007, the employees moved to the new, state-of-the-art facility shown in the adjacent photo. This 480 m2 (5,100 ft2) building has passive solar windows, and an open internal architecture to provide natural lighting to all work stations. The building has radiant floor heat and is “super-insulated” to reduce energy costs, and increase comfort. The roof has an R-value of 80, the walls are R-40, and the low-E thermopane glass has an R of 3.4. The building is monitored and controlled with a Campbell Scientific CR3000 datalogger coupled to 64 multiplexer input channels and 32 output control channels. Internal and external temperature, humidity, CO2, O2, air velocity, and solar radiation are graphed on large displays on the wall. The company logo on the roof is visible from commercial aircraft flying at 8,000 meters. Visitors are always welcome to stop by for a tour. We are proud of where we work.
