This is a Best of the Forum session. States and local governments are actively developing policy approaches aimed at driving towards zero energy and/or zero carbon new buildings and deep emission reductions for existing buildings. Across jurisdictions, successful strategies involve a combination of voluntary programs, policy tools, and codes. Presenters from New York State, Metro Boston and Denver will provide a snapshot of approaches that are being taken in their jurisdictions across North America to achieve energy and carbon goals by leveraging voluntary programs, mandatory and stretch codes, and other local government tools to drive change.
