Laboratories Best Practices: Energy Recovery for Ventilation Air in Laboratories

Steven G. Liescheidt, P.E., CCS, CCPR

Energy recovery can substantially reduce the mechanical heating and cooling requirements associated with conditioning ventilation air in most laboratories. Laboratories typically require 100% outside air at high ventilation rates, between 6 and 15 air changes per hour, primarily for safety reasons. The heating and cooling energy needed to condition this air, as well as the fan energy needed to move it, is 5 to 10 times greater than the amount of energy used in most offices for those purposes. Heating and cooling systems can be downsized when energy recovery is used, because energy recovery systems reduce peak heating and cooling requirements.

This course is based on the document Laboratories For The 21st Century: Best Practices Energy Recover For Ventilation Air In Laboratories, DOE/GO-102003-1774 October 2003.

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