Water Efficiency Management Guide for Mechanical Systems

COURSE NO: M02-055
Water Efficiency Management Guide for Mechanical Systems
Course Highlights

This online engineering PDH course presents guidelines on how to reduce mechanical system water use in residential buildings. Mechanical systems are frequently utilized to provide heating and cooling for residential properties. They typically fall into two categories: centralized and decentralized systems.


Centralized mechanical systems provide heating and cooling from a central location, such as a mechanical room or utility penthouse. These systems are more common in mid- and high-rise multifamily properties and can include cooling towers, boilers, and steam systems, each of which uses water as the heat transfer medium. As a result, the use of water for building heating and cooling can be significant and using sound management practices is a good opportunity for water savings.


Decentralized mechanical systems treat each unit of a multifamily property as its own space, as if each unit were a stand-alone single-family residence. These systems do not typically use process water, so they are not the focus of this water efficiency management guide.


This 2 PDH online course is intended for mechanical, environmental and civil engineers, as well as other technical personnel who are interested in learning more about reducing water use in mechanical systems.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the basics principles behind single-pass cooling, cooling towers and boiler/steam systems
  • Understanding mechanical system water use
  • Familiarizing with the maintenance and best management practices
  • Knowing the mechanical systems retrofit and replacement options 
  • Familiarizing with the water savings calculations and assumptions
