Under the proposal, buildings in excess of 50,000 square feet -- which represent less than 1 percent of the city's buildings but 22 percent of buildings total energy consumption -- would be required to disclose energy consumption data and information about building size, use and occupancy levels into a software program like TurboTax administered by the U.S. EPA. The "benchmarking" tool, called Energy Star Portfolio Manager, would then compare the energy efficiency of comparable buildings. It is hoped that the scores will motivate business owners to improve through upgrades.
