Ancient Roman seawater concrete could teach us how to cut carbon emissions
In a quest to make concrete more durable and sustainable, an international team of geologists and engineers has found inspiration in the ancient Romans, whose massive concrete structures have withstood the elements for more than 2,000 years. The discovery could help improve the durability of modern concrete, which within 50 years often shows signs of… »

Green architecture – UC Davis Student Community Center
The University of California recently set a minimum requirement that all new buildings meet standards equivalent to LEED Silver certification. New buildings are also required to be at least 20 percent more energy efficient than California code requirements. But the Davis campus has set their bar even higher – new buildings on the campus should… »
