How Maintenance Affects Energy Performance

Equipment does not lose efficiency all at once; it drifts downward gradually as it fouls, wears and falls out of adjustment. Understanding these mechanisms is what shows why maintenance is an energy measure, not just a reliability one, and why deferring it is usually a false economy. This lesson covers how equipment loses efficiency, the cumulative effect, maintenance as efficiency recovery, and the hidden cost of deferral, echoing the commissioning drift the commissioning course describes.
