Buildings Seeking LEED to Provide Performance
June 26, 2009
As part of LEED v3, the latest version of the U.S. Green Building
Council's program for green building design, construction, operations
and maintenance, buildings seeking LEED certification will begin
submitting operational performance data on a recurring basis as
a precondition to certification. USGBC will be able to use the performance
information collected to inform future versions of LEED.
"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
- 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
- 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.
"USGBC is proactively investigating cost effective ways for
every LEED building to become metered as a way to capture this data,"
said Brendan Owens, USGBC's vice president of LEED technical development.
"However, we know that there are building types that may have
a central plant, a military base or a university campus, for instance,
where it would be cost prohibitive to install meters on every single
building," said Owens. In this circumstance, the MPR would
