Instead of choosing an existing building to move into or even vacant land on which to build, DST Output chose to renovate an abandoned railroad roundhouse.
Rooftop units have come a long way in recent years. They now contain more sophisticated controls, improved serviceability features, and unique ways to address indoor air quality (IAQ) issues. But even the best-made rooftop can’t keep soldiering on if routine maintenance is not performed regularly.
Rooftop units toil away during the day under hot conditions; consequently, their energy efficiency, as compared with chiller systems for building cooling, is generally much lower. One manufacturer, Calmac Corp., has created the Roofberg® system, which permits conventional rooftop units to be converted to a central chiller system with ice storage.
Is it really possible to implement Ken Blanchard’s Gung Ho! techniques? And if so, how difficult is it? Those are some of the questions that were answered by employees (or coworkers, as they like to be called) of Secco Inc.

Thinking about your own imminent demise (read: death) is never a subject we like to dwell on. However, if you own a business, it’s necessary to start thinking about it while you’re still sound in mind and body. That would be today for those who have not yet made the necessary provisions.
Two products are being introduced to provide users with increased motor performance, as well as greater flexibility and functionality. Rockwell Automation has released its Allen-Bradley smart motor controllers, the SMC-3™ and SMC-Delta™.
According to some studies, the addition of vfd’s to an existing system can result in a reduction in energy consumption of 30% to 60%. For this reason, vfd’s are becoming quite popular. Since the technology has become much more stable over the last few years and costs are coming down, it’s a good time to look at vfd’s.
Most of the time it’s not a question of whether or not to replace a motor. By the time a contractor is called to the scene, the motor has already failed or is in its death throes. Replacement is usually a viable solution, because repairing a motor can be fairly expensive.
