Washington, D.C., May 8,
2008 — The American Institute of Architects (AIA) has released a study
of three green building rating systems (Green Globes, SBTool 07,
and LEED NC 2.2) and assess their effectiveness in supporting the
goals of the AIA sustainability position statement. In late 2007,
the initial results were shared with the three groups whose systems
were reviewed. After receiving feedback, the study was modified and
further refined into the final report.
The purpose of this exercise is to offer analysis to both industry
and the public as an opportunity to learn how three unique,
creative and evolving green building rating systems resonate in
various dimensions with the goals of the AIA position statement on
sustainability and our goal to achieve carbon neutrality in
buildings by 2030.

“This study is not a report card or ranking of the various
standards,” said AIA Executive Vice President/CEO Christine
McEntee. “The intent is to offer design and construction
professionals an in depth review of the three systems with
particular emphasis on areas for improvement in relation to more
rigorous energy conservations requirements.”

Sustainability”
“We reviewed these particular systems because they are the
most broadly used in the U.S. market and they take a comprehensive
approach to evaluating an entire building,” added AIA
President Marshall Purnell, FAIA. “With new sustainability
continuing education requirements in 2009 for AIA membership the
results of this study can help better inform our members and the
profession on green rating systems as they relate to our carbon
reduction goals.”
Key findings:
Green Building Initiative’s Green
Globes:
The system offers a broad based evaluation of projects in both the
design process and based on environmental criteria. When used to
certify a project, more stringent and specific requirements in the
areas of energy reduction and operational performance are needed,
as these are the two areas that most influence carbon
production.
U.S. Green Building Council’s LEED NC 2.2
system:
This is good example of a rating system which provides a
measurement of environmental achievement. Continued developments in
life cycle assessment, requirements for renewable energy or carbon
reduction targets for certified projects will continue to make this
system an effective resource for architects.
International Initiative for a Sustainable Built
Environment’s SBTool 07:
SBTool 07 is a toolkit for designing a rating system. If used as a
rating system providing certification, SBTool 07 would be stronger
if there was an increase in the number of “required”
items vs. those that are simply “encouraged” and required
project documentation. Specific requirements in the areas of energy
reduction and operational performance would supply any rating
system approach that comes out of SBTool 07 with performance-based
requirements necessary for reaching carbon reduction goals.
About The American Institute of
Architects
For over 150 years, members of the American Institute of Architects
have worked with each other and their communities to create more
valuable, healthy, secure, and sustainable buildings and
cityscapes. By using sustainable design practices, materials, and
techniques, AIA architects are uniquely poised to provide the
leadership and guidance needed to provide solutions to address
climate change. AIA architects walk the walk on sustainable design.
