An American architecture professor at a university in the Middle East is developing an energy-saving way to make bricks using bacteria known for its ability to solidify sand. Ginger Krieg Dosier, assistant professor of architecture at the American University of Sharjah in the United Arab Emirates, has developed a method that involves filling a form with alternating layers of sand and a solution containing urea, calcium chloride and the non-pathogenic Sporosarcina pasteurii (or Bacillus pasteurii). Within a few days, a chain of chemical reactions yields a mineral growth that seeps between the grains of sand and “biocements” them together into
In the three years leading up to the current recession, gross billings at U.S. architecture firms increased nearly $16 billion from 2005 and totaled $44.3 billion in 2008. That equates to 54 percent growth over three years with annual growth of about 16 percent. These findings come from the American Institute of Architects (AIA) “Business of Architecture: AIA Survey Report on Firm Characteristics,” which is conducted every three years to examine issues related to the business practices of AIA member-owned architecture firms. Top 10 sectors served by architects in 2008 Healthcare: 18.2% Office space: 11.3% Education (K-12): 9.0% Education (college/university):
