Green building has taken a firm hold on architects and their clients, according to a new survey of architects conducted by the American Institute of Architects (AIA) and Autodesk, Inc.
The 2007 Green Index survey finds that 70% of architects say client demand is the leading driver of green building. The primary reason is that a large number of owners and developers (64%) want the reduced costs required by greener buildings. Architects are responding by significantly increasing the use of sustainable elements such as high-efficiency HVAC systems and recycled building materials, and by using software to model energy usage.
Just five years ago, less than half of architects were using sustainable design practices in their projects, according to the survey. Ninety percent of architects expect to incorporate some sustainable elements by 2012, the survey found.
Architects have embraced sustainable design in a variety of ways, according to the survey. Eighty-eight percent of respondents have received training or continuing education focused on green building, for example. The industry has also seen a 25% increase in the number of architects utilizing high-efficiency HVAC systems in their projects over the past five years. Other areas of growth include the use of highly-reflective roofing materials (+18% since 2002), and the adoption of energy modeling and baseline analysis (+17% in the same period).
The Green Index was conducted online in October 2007 among 347 practicing architects in the United States. The architects were questioned on their use of 14 green design practices--based on the USGBC’s LEED standards—currently, five years ago and what they expect five years from now.
