Optimizing how fans work functionally in mechanical applications can reduce energy use and save energy dollars for end users. Assuming the design engineer selected the proper fan and proper installation in well designed system what can a facility manager do to save energy dollars and increase performance by looking at the fan systems in their building(s)?
