Leadership in Energy Design... and Performance?
Seems as if green building is not only here to stay, it is the one bright light in the otherwise dark or dim construction industry. Nonetheless, there is growing criticism--and response---about perceived deficiencies with the current LEED rating systems.
We have reported robust predictions for green building in previous blogs. Green building now accounts for nearly one third of new construction in the U.S., up from 2 percent in 2005, according to McGraw Hill Construction. Currently, LEED certification comes after construction of the particular structure, with no relationship to that structure's operational performance in terms of energy efficiency or carbon footprint. Green building certification does not ensure lifelong energy efficient performance, something critics believe should be accounted for in a green building rating system.
USGBC responded to this criticism by launching its Building Performance Initiative last summer. After a series of area summit meetings with local, state and federal government representatives, USGBC chapters, developers, architects, engineers, builders, and other construction professionals, USGBC has created the Building Performance Partnership (BPP). BPP is collecting water and energy use data from LEED certifed buildings, which are required to be reported under LEED's 2009 rating systems. Recently, current LEED certified building owners were invited to participate in BPP.
USGBC assures its users that reports will not be used to decertify existing certifications. In a recent press release, USGBC states BPP "will result in the population of a comprehensive green building performance database and enable standardization of reporting metrics and analytics to establish new building performance benchmarks." Currently, more than 120 projects are participating in BPP, and USGBC says these projects will receive a basic performance report in time for its Greenbuild 2010 conference in November this year.
Critics don't think this goes far enough, and think the federal government should lead the charge to establish building performance requirements. Phil Bernstein, vice president of Autodesk, Inc., a San Rafel, Calif., engineering and design software company, suggests "The USBGC should make it so that the LEED Platinum plaque pops off the wall if the building fails to perform."
Expect continuing developments and requirements in the green building performance arena, from USGBC and other rating agencies, along with the federal, state and local governments. In the meantime, I am pleased to report that our Seattle office building recently achieved a LEED Silver rating under LEED's existing buildings program... more to report later!
