Energy and Air Barriers – Navigating the New Codes

Join us as we review the theory and historical progression of air tightness requirements and understand the metrics that provide the baseline for levels of air tightness.
Over the past decade, energy codes have brought a number of changes with respect to improving the performance of the building envelope both in design and construction. Most notable is the increasing importance placed on air‐leakage through the enclosure and how this often unknown value affects many of the energy efficiency metrics that define the performance of the building. Currently, there are multiple codes and standards requiring varying levels of air tightness as well as varying levels and methods of verification. As the requirements and performance implications become better understood, common design and construction practices will experience shifts toward better performance as was experienced in the early years of the USACE requirements on which the private sector codes are based.
