In the three years prior to the current recession, the number of architectural firms doing green design projects nearly doubled, as did the number of firms using Building Information Modeling (BIM) software, the American Institute of Architects has reported.
Billings at U.S. architectural firms topped $44.3 billion in 2008, according to the AIA Business of Architecture survey. AIA conducts the survey every three years.
U.S. architectural billings increased nearly $16 billion from 2005 to 2008, representing an annual growth rate of some 16% and some 54% growth for the three-year period.
Fifty percent of architectural firms reported using green design practices in the most recent survey, up from 31% in 2005. Nearly two-thirds of construction projects started in 2008 had sustainable design features.
Other highlights of the report include:
The share of firms using BIM software rose from 34% in 2005 to 69% in 2008.
New construction accounts for nearly two-thirds of all design projects, AIA members reported.
Traditional design-bid-build delivery method is the most widely used by architecture firms.
International projects accounted for some 7% of billings in 2008, totaling more than $3 billion in revenue.
The current survey reports the results of a scientifically selected sample of 2,700 architectural firms and was conducted early this year.
