Buildings are big energy consumers. Inefficient buildings can be a significant drain on the grid, which can trigger electrical brownouts and blackouts during peak usage times.
In 2013, Chicago became the ninth U.S. city to pass an ordinance requiring large buildings to track their energy use. Chicago’s City Council approved the proposal from Mayor Rahm Emanuel to create the Chicago Energy Benchmarking program, which establishes requirements for all commercial, residential and municipal buildings larger than 50,000 square feet to monitor and publicly report their energy use.
