Now there are cities that have taken the lead on green building with 15 benchmarking or disclosure laws which require owners to report their buildings’ annual energy usage to the local government. In addition, some have adopted more building laws which require that new buildings achieve higher energy efficiency than is set in base code.
Benchmarking and disclosure laws appear to have the most impact as they are require owners report their annual energy usage. This expert point out that it is still in early stages but the mere existence of these laws and the fact owners must report is leading to change.
One way owners have achieved this change is big data:
Most of the early advances have come from use of “big data.” New companies have sprung up to provide real-time, energy-use data—often at 15-minute intervals—to building owners to help them better understand daily patterns of energy use, identify anomalies when and where they occur, and optimize operational improvements.
