All LEED Projects to Provide Actual Performance Data

With the April 27, 2009, release of the LEED 2009 family of rating systems, the U.S. Green Building Council (USGBC) introduced a new element to its LEED package: minimum project requirements (MPRs). They vary slightly by rating system, but in general they aim to exclude structures from LEED that are too small, unoccupied, or mobile. They require a reasonable site definition, and compliance with environmental laws. Most significantly, they require owners of all certified projects to provide energy- and water-use data to USGBC for five years from the time of occupancy.
