At the top level of this energy-efficient building, an adhered air barrier provides the primary weather protection for a metal panel cladding system, to be installed.
Energy codes mandating more efficient use of buildings—and, by extension, of building enclosures—are already being adopted by many states as a logical step in the reduction of energy consumption. On a national scale, the impetus to improve building energy performance
is manifest in the latest and most far-reaching model energy code from the International Code Council, the 2015 International Energy Conservation Code (IECC). Compared with energy standards of just a few years earlier, the 2015 IECC sets a high benchmark for energy performance.
After reading this article, you should be able to:
+ BALANCE energy use goals with practical considerations, such as constructability, performance, and product availability.
+ APPLY principles of thermodynamics and energy transfer to the appropriate design of energy-efficient building enclosures.
+ DETERMINE energy code compliance by demonstrating thermal efficiency through calculations or energy modeling.
+ ACCOUNT for sites of thermal bridging by incorporating high-efficiency detailing that addresses sources of energy loss and insulates against heat transfer.
