Greek Philosophers, Radial Tires and HVAC Game Changers. Say What?

Posted by Robert Chiste on Aug 11, 2017 9:41:07 AM

Somewhere around 500 BC the Greek philosopher Heraclitus, who is known for his doctrine of change being central to the universe, made a profound statement that is still often quoted: “The only thing that is constant is change.”

As business leaders, we are all too familiar with this adage because we deal with change every day, and our ability to anticipate and manage change often underpins the continued survival of the organizations that we lead.

Change takes place along a spectrum ranging from evolutionary to revolutionary.  Evolutionary change is often imperceptible until one steps back and views the change or transformation over a long period of time. Evolutionary change could be viewed as “change on the edges” – changes needed just to remain competitive.

Revolutionary change on the other hand can be disruptive to an entire industry and almost instantly result in winning and losing participants in that industry.

Staggered Starts for RTUs Save Money

Posted by Robert Palmer on May 25, 2017 8:30:00 AM

In commercial and industrial facilities, rooftop units (RTUs) are usually turned off or greatly curtailed during unoccupied periods, for example, overnight and/or on weekends. Unfortunately, too little attention is given to the schedule RTUs are programmed for restart. If the desired setpoint is reached too early, energy is wasted, while reaching it too late adversely affects occupant comfort. Optimizing RTU start times means programming each RTU so as to reach its desired space temperature setpoint at the intended time. However, many facility managers fail to appreciate the energy and cost savings benefits of optimizing their HVAC startup schedule and simply program RTU start times to ensure they start early enough to guarantee the setpoints are reached before start of business.
