This course addresses new code requirements for the 2012 IECC, the IgCC, and ASHRAE 189.1 for continuous insulation, maximum fenestration area, and the use of air and moisture barriers. Designers and specifiers are advised how to boost insulation, control air leaks, reduce solar heat gain, and keep moisture out of the building envelope, through greater attention to the specifications for exterior insulation for both new construction and reconstruction projects.
After reading this article, you should be able to:
+ DESCRIBE the new requirements for enclosure features such as continuous insulation (CI) and air barriers in the 2010 and 2012 codes and their impact on environmental performance.
+ LIST the benefits and drawbacks of commonly used cladding systems, especially with regard to indoor air quality and mold.
+ describe performance issues of cladding and exerior insulation systems.
+ explain several key areas of detailing and specification for successful wall performance as related to sustainable design and construction.
