Opaque Envelope Basis of Designs

Developed to be IBC 2015, IECC 2015 and NFPA 285 Compliant (where indicated) for Climate Zones 5 & 6

The following opaque envelope wall Basis of Design (BOD) packages have been developed to assist owners, architects and contractors in the selection, specification and detailing of exterior wall assemblies that are code compliant, and based on building science fundamentals.  Assemblies in the wall BODs strive for the concept of the Perfect Wall and are recommended to meet the requirements of the IBC 2015, IECC 2015 (Climate Zones 5 & 6), NFPA 285 acceptance criteria when applicable, and LEED v4 Fundamental Commissioning requirements for exterior wall assemblies.  Dew point analysis are based on ASHRAE 99.6% winter outdoor design conditions for the greater Boston area and best practice indoor design conditions for typical uses.  Appropriate use and application of the assemblies illustrated in these BODs will vary based on performance considerations and environmental conditions unique to each project and, therefore, do not represent the final opinion or recommendation of PACE Representatives or represented manufacturers.  Contact PACE Representatives to develop a custom wall BOD package to meet your project specific performance requirements and design conditions.

*NFPA 285 compliance for assemblies is demonstrated using one or more manufacturer's third-party NFPA 285 engineering evaluation(s) per IBC Section 104.11 Alternative Materials, Designs and Methods of Construction and Equipment.
