The U.S. Department of Energy recognized Lawrence Berkeley National Laboratory in the area of advanced technologies and practices for research on high-efficiency furnace blowers. The project team consisted of Iain Walker, Darryl Dickerhoff and Jim Lutz of the Environmental Energy Technologies Division.  Their work is credited with leading to the incorporation of energy-efficient blowers in U.S. energy efficiency programs and building codes, and the creation of a Canadian standard for rating air system blowers.
