For the second year in a row, 5 is spotlighting one of our most innovative and iconic clients, Empire State Realty Trust. Earlier this month, ESRT announced their groundbreaking Empire Building Playbook: An Owner’s Guide to Low Carbon Retrofits. This publication, co-supported by NYSERDA and the Clinton Global Initiative, will help existing commercial buildings implement step-by-step carbon reduction processes with proven methodologies. 5 is proud to be among the core project team that helped ESRT with this game-changing playbook.
