This spring, the American Institute of Architects unveiled the latest updates to its core set of documents, and the addition that has the AEC industry buzzing is the Sustainable Projects Exhibit (E204–2017). Every 10 years, the AIA updates its documents to reflect changes to the industry and set new standards for negotiations between architects, contractors, clients and consultants across the country. For this round, seasoned architects like Tracy Lea, principal at Eskew+Dumez+Ripple in New Orleans, helped AIA address changes in sustainable design. The result is a flexible, effective and deceptively simple Exhibit that can be attached to standard contracts, specifying the roles and expectations for all parties working toward a greener building.
