Building and energy codes are developed and updated in a very open, transparent, and inclusive process following a three-year cycle. Other standards and programs are recognized by the codes, particularly the IECC, as alternative ways to show code compliance. Updates specific to the 2021 I-Codes address issues related to WRBs in walls that may hold water, such as stucco. The design and specification of glazed entry systems require attention to detail of all of the components to understand the total performance and code compliance. Architects who recognize the interrelatedness of the code development process and day-to-day design and construction work will achieve better understanding of effective building performance and code-compliant strategies.

Peter J. Arsenault, FAIA, NCARB, LEED AP, is a nationally known architect, consultant, continuing education presenter, and prolific author advancing building performance through better design.,
