HVAC Guide to Demand Control Ventilation

A. Bhatia, B.E.

Concerns about rising energy costs, as well as growing interest in the LEED (Leadership in Energy and Environmental Design) rating system, has led to increased attention towards demand control ventilation (DCV). DCV is a ventilation control strategy that provides just the right amount of outside air the humans need, and no more. This accomplishes two things. First it saves energy by not heating or cooling unnecessary quantities of outside air. Secondly, it can provide assurance that sufficient outside air is being supplied for the number of occupants present.

This 4-hr course provides the framework necessary for integrating DCV into a HVAC system and includes background on ASHRAE ventilation standards. The course will take reader through the design process and calculations needed to understand, how to properly implement DCV strategy.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
