One of the first actions by Mayor Michael Nutter upon his election in 2008 was to create the Mayor's Office of Sustainability. This body spearheaded the development of Greenworks Philadelphia, an ambitious plan to improve the city’s energy, environment, equity, economy, and engagement with the goal of becoming the greenest city in America by 2015. In light of these plans, advocacy groups like the Coalition for an Energy Efficient Philadelphia and the Energy Efficient Buildings Hub began working with the city on benchmarking requirements. On May 17, 2012, Philadelphia City Councilwoman Blondell Reynolds Brown introduced Bill No. 120428, mandating that all large commercial buildings in Philadelphia benchmark and disclose their energy and water use. The ordinance was adopted as § 9-3402 of the Philadelphia Code. In March of 2015 the Philidelphia City Council voted unanimously to amend § 9-3402 to include multifamily buildings over 50,000 square feet.
