Integrative design case studies: pump systems

Based on discussions with engineer Eng Lock Lee, a well–engineered redesign of many pumping systems will yield 80–90% savings. In these examples, many of these savings came from piping enhancements, the use of variable speed drives, digital sensors, the removal of oversized equipment, and high-efficiency equipment.

 

Energy efficiency in piping design

There are simple but important opportunities to save energy through improved piping design. For instance, pipes are often laid out at right angles rather than in a geometry that minimizes friction and cost.

 

Energy inefficiency in a conventional data center

Starting the savings downstream at a typical data center can achieve leverage of 10- or even 100-fold in saved fuel back at the power plant.
