Dr. Amy Allen is a mechanical engineering researcher at the National Renewable Energy Laboratory in Golden, Colorado. Her work focuses on advanced district thermal energy systems and applied heat pump and heat recovery systems, as well as de-risking of such systems through laboratory experimentation. Amy’s research interests also include development of flexible modeling and analysis tools for district thermal energy systems. Amy is especially interested in addressing challenges to adoption of advanced district energy systems in older existing buildings. Prior to joining NREL, Amy worked as an engineer at kW Engineering in Oakland, California, where she performed energy audits and retro-commissioning studies for utility programs. Amy received her doctorate in architectural engineering from the University of Colorado Boulder, where her research focused on network topology optimization for advanced district thermal energy systems. Amy is a licensed mechanical engineer.
