Energy Recovery for Laboratories

The guide is part of a series on energy recovery best practices for laboratories. It was produced by Laboratories for the 21st Century (Labs 21), a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. Geared toward architects, Group14 Engineers, and facility managers, these guides provide information about technologies and practices to use in designing, constructing, and operating safe, sustainable, high-performance laboratories.

  • Laboratories typically require 100% outside air at ventilation rates between six and 15 air changes per hour.
  • Energy recovery can substantially reduce heating, cooling and humidification loads associated with conditioning ventilation air in 24/7 buildings.
  • Energy recovery also provides additional capacity for heating and cooling.


Installing energy recovery systems can substantially reduce the cost and use of energy in laboratories. Selecting an appropriate energy recovery technology, properly designing the system, meeting the applicable codes, and commissioning the system are all important. When an energy recovery system is designed, installed, and operated correctly, it will provide significant energy and environmental benefits.
