Unformatted text preview: It was noted during field observation that the reduction occurred primarily due to the
introduction of an audit system, but that the reduction was unable to be maintained beyond two
weeks. During times of peak observed efficiency, the reduction in total process energy using the
approach was 26% compared to control, and the reduction in electricity waste was 43%. However, it
is hypothesized that a more likely sustainable level of improvement from feedback is probably around
10-15%, as noted in residential studies in the literature, though more data is needed to prove that
result beyond what was collected in this study. Additional analysis showed that potential continuous
improvement approaches including optimization or automation could further reduce energy usage of
the ovens by 15%.
Finally, the best practice of right-sizing equipment was analyzed in the context of select systems
at the IADC as well as through existing literature. While specific estimates on savings do not generally exist for process equipment, a literature review indicates that installing newer, smaller
motors can reduce overall electricity use of motors in industrial support systems by 11% nationwide.
