E – 1792 HVAC – Demand Control Ventilation
$100.00
Courses Included
The ventilation rate inside a building is directly dependent on the number of occupants in the space. If we had the ability to economically count each person as they enter and exit the space, then we could provide exactly enough ventilation air to meet the needs of the quantity of people in the space. But in most buildings occupancy is not tracked in real-time and therefore finding the right balance in ventilating your building is a challenge.
Most HVAC engineers and designers design ventilation system on the maximum anticipated building occupancy. This results in a waste of energy and money, due to over-ventilation during lean periods. Demand Control Ventilation (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.
