As part of the latest version of the United States Green Building Council's LEED green-building rating system, buildings seeking certification will now have to submit operational data on a recurring basis as a precondition to certification, USGBC announced.
"Today there is all too often a disconnect, or performance gap, between the energy modeling done during the design phase and what actually happens during daily operation after the building is constructed," said Scot Horst, senior vice president of LEED, U.S. Green Building Council. "We're convinced that ongoing monitoring and reporting of data is the single best way to drive higher building performance because it will bring to light external issues such as occupant behavior or unanticipated building usage patterns, all key factors that influence performance."
Projects can comply with the performance requirement in one of three ways:
The building is recertified on a two-year cycle using LEED for Existing Buildings: Operations & Maintenance.
The building provides energy and water usage data on an on-going basis annually.
The building owner signs a release that authorizes USGBC to access the building's energy and water usage data directly from the building's utility provider.
The requirement creates a data stream on LEED-certified building performance that can be used by owners and operators to optimize their building performance and promote the establishment of energy efficiency goals over the life of the building, according to USGBC.
