PNNL

Stephanie Johnson, a mechanical engineer at the Pacific Northwest National Laboratory (PNNL), has been recognized with an Industrial Assessment Center (IAC) Distinguished Alumni Award.

The award is given by the U.S. Department of Energy Advanced Manufacturing Office to honor past and present IAC students who have made a significant impact through their work in energy efficiency. It also recognizes outstanding accomplishments in promoting practices and principles of energy engineering.

The IAC provides no-cost energy assessments to small- and medium-sized manufacturers to help them improve productivity and competitiveness, reduce waste, and save energy. There are 31 IAC teams located at 31 universities across the nation.

Johnson was nominated by John Gardner, her undergraduate mentor and assistant IAC director of the Boise State University team.

She has conducted energy audits of more than 100 commercial and government buildings that have spurred recommendations resulting in significant energy savings. Since beginning her energy-efficiency career, she has evaluated more than 6 million square feet for energy- and water-efficiency improvements within government facilities. These efforts have generated an estimated energy savings greater than $1.5 million (58,000 metric million British thermal units) in energy savings and more than $35,000 (5,200 kilo gallons) in water savings.

Johnson joined PNNL in 2013 as part of the Buildings and Connected Systems team. She has made significant contributions to several energy-efficiency projects, including building energy-efficiency modeling for the U.S. Army Reserve, energy consumption reduction in buildings through optimization of advanced control strategies, and development of enterprise building control systems.
