Frequently efforts to improve efficiency focus on the individual equipment involved and how it's operated. The ultimate efficiency of a given piece of equipment is substantially a matter of original design and cannot be significantly changed. As energy professionals, what we do have control over is the equipment that is operated for a given system load condition. This discussion focuses not on HOW to operate equipment but WHAT equipment to operate. The best way to understand this concept is to use an analogy that everyone can relate to. In this case we will use automotive fuel economy in the form... Continue reading

A common problem with industrial facilities is a negative air balance. As processes are added or expanded, the amount of exhaust is increased, frequently without additional fresh-air supply. Over time, the facility becomes increasingly negative pulling outside air into the building through every gap and available opening. In winter months, this air infiltration around the perimeter of the building causes comfort issues for workers and drives supplemental heat requirements. If, for the sake of this discussion, we ignore the fact that uncomfortable workers are a problem - the energy issue that can be created is the nature of the supplemental... Continue reading

The Hierarchy of Energy Conservation represent a path to improved energy management and a way to evaluate the quality of the final selection. The Hierarchy of Elimination, Reduction, Substitution, Controls, Procedures, and Awareness forms a descending order of energy conservation value as well as a progression of inquiry to provide consistently better outcomes.

Increasingly, studies are showing that conservation and more efficient technologies provide the least-cost energy alternative on a dollar per kW or BTU basis. It's simply less expensive to modify our practices to use less energy than to develop new ways to feed inefficient practices. This is the main focus of my professional activity and the driving purpose of this Blog. Continue reading
