Johnson Controls developed the LEAN energy analysis technology over the past eight years and has used the tool to analyze retrofit opportunities in over 700 buildings. Berkeley Lab is working with Johnson Controls to automate and improve the LEAN energy analysis tool and create an open-source version of the tool for public use.
