Claire McKenna

Claire is a former Senior Associate at Rocky Mountain Institute, where she researches the techno-economic case for building electrification in the US. By developing tools to advance knowledge and fostering collaborations across industry, municipalities and utilities, Claire supports RMI’s goal to eliminate the use of fossil fuels in buildings by 2045.


Prior to joining RMI, Claire led the sustainable building design practice at WSP in Boston. In that role, she worked with architects and developers to deliver high performance buildings that meet government and corporate mandates for climate action and resiliency. Her team incorporated planning and modeling for all-electric buildings, passive design strategies, and alternative energy strategies into projects across the country.

Claire began her career as an electrical engineer in the US solar photovoltaics industry and is a technical expert in strategic distributed energy resource (DER) planning and design.
