New rating system resets the bar for green building performance.
LEED 2009, the
long-awaited update to the internationally recognized LEED green building
certification program, passed member ballot Nov. 14. It will be introduced next
year as “the next major evolution of the existing LEED rating systems for
commercial buildings,” according to the U.S. Green Building Council.
2009 includes a series of major technical advancements focused on improving
energy efficiency, reducing carbon emissions, and addressing other
environmental and human health outcomes.
2009 will also incorporate highly anticipatedregional credits― extra points that have been identified as priorities within a project’s given
environmental zone. LEED has also undergone a scientifically grounded re-weighting
of credits, changing allocation of points among LEED credits to reflect climate
change and energy efficiency as urgent priorities.
new updates incorporate eight years’ worth of market and user feedback in the
form of precedent-setting Credit Interpretation Rulings, which will ensure
clarity for project teams,” USGBC announced. The organization hopes to “reset
the bar” for the certification of high-performance green buildings.
2009 will also take into account new technical advancements through a new “pilot
process” for individual credits that will allow major new technical
developments to be flexibly trialed, evaluated and incorporated into LEED.
first public comment period for LEED 2009 opened in May 2008, followed by a
second in late August. USGBC received nearly 7,000 comments from members and
stakeholders at the conclusion of the second public comment period Sept. 2. The
final step in the consensus development process for LEED 2009 was to be
balloted for a pass/fail vote among USGBC’s 18,000 member organizations. LEED
2009 successfully passed member ballot Nov. 14.
