You can use the pictures to help jog your memory while planning and they can serve as a record of the opportunity in your reports. 5. Don’t send a boy to do an engineer’s work. The assessment is your one opportunity to “find” the improvements. Make sure those conducting the survey are not just data gatherers. Assign plant engineers or top maintenance personnel to perform this function and use the time in the field to allow your engineers or technicians to use their imagination to come up with good ideas. Every survey our company performs ends with definite energy and cost savings solutions to recommend. Finally, it’s important to emphasize how important it is to track and monitor energy consumption and cost before and during an Energy Conservation Program.

The old adage is especially apt here - How can you manage something you don’t measure? However, good data collection and interpretation are more important than just tracking success. Energy data can also be the key to finding, correcting, and optimizing energy systems. The more data and the more frequent the reporting the better. For example, many manufacturing plants are charged electric demand as well as usage. Spikes in demand at certain times of the day can dramatically increase the customer’s monthly charge. Collecting and reviewing electric meter interval data on a regular basis can reveal anomalies that could be adding considerable cost to the customer’s energy budget. Reviewing and interpreting this data can be both very useful and cost effective in tracking an Energy Conservation Program.
