Dr. Ralph T. Muehleisen is the Principal Building Scientist, the Building Energy Decision and Technology Research (BEDTR) Group leader, and the Urban Science and Engineering Program lead for Argonne’s Energy Systems division. At Argonne, Dr. Muehleisen leads research to increase the energy efficiency and resiliency of the built environment while improving the quality of life and return on investment for citizens. His projects include urban science and engineering, stochastic building energy modeling, reduced order building energy modeling, risk analysis of building energy retrofits, Bayesian Calibration methods for building energy models, agent based models for understanding adoption of retrofit technologies, smart building/smart grid integration, and the development of new energy efficient and diagnostic technologies buildings. Dr. Muehleisen is the author of over 180publications and presentations, and is a frequent invited speaker in the areas of urban science and engineering, building energy modeling, architectural acoustics and noise control.
She is a member of the Building Envelope Systems Research Group at Oak Ridge National Laboratory (ORNL) with her current research includes evaluating the performance of easy-to-install air barrier technologies, examining the feasibility of new air leak detectors for building enclosures, assessing the cost-effectiveness of various techniques to retrofit commercial building envelopes, and exploring the potential use of advanced manufacturing in building envelopes. In 2015, she was selected among researchers who were collaborating under the U.S.-China Clean Energy Research Center for Building Energy Efficiency (CERC BEE) to brief Secretary of Energy Ernest Moniz on advancements in air sealing technologies. As a continuation of this work, she is leading a project under the second phase of CERC BEE aiming to improve the energy performance of architectural insulated concrete precast panels using latest developments in advanced composites, 3D printing, and material science. With the support from the National Science Foundation, she received a doctorate in civil engineering from the University of Texas-Austin for her work on human exposure to hazardous air pollutants in homes. She is a registered professional engineer (inactive) and a Leadership in Energy and Environmental Design (LEED) Accredited Professional.
