The use of an exterior barrier will also be required. This requirement is being enacted to eliminate energy loss due to thermal bridging associated with framed walls using only cavity insulation. One of the mandates in this standard is the expanded use of continuous insulation in climate zones 3 through 8, approximately 90 percent of the U.S. Department of Energy (DOE) has mandated that by October 18, 2013, all states must adopt a commercial building energy code (IECC or IgCC) that meets or exceeds ASHRAE Standard 90.1-2010. However, when contractors use established technologies with documented performance and understand when and how to apply them, the results are often successful. Often, the contractor is challenged to bid and construct with materials and systems before they have been tested in terms of performance and ROI. Sustainable building is a growing trend but still represents a challenge to contractors with regard to measurable performance. Contractors should be aware of the building envelope technologies available to achieve goals of both aesthetics and performance. However, it also plays an important role in maximizing energy efficiency, climate control and indoor air quality. The exterior building envelope plays an obvious role in aesthetics. At some point, whether during construction or renovation, building owners rely on their architects and contractors to select materials that will help them achieve their goals and maximize ROI. Most commercial building owners want their buildings to have “curb appeal.” Some compete for tenants, others compete for customers and all want to satisfy and attract employees.
