Mission

The RESNET SDC 300 Enclosures Sub-Committee is tasked with maintaining and improving RESNET’s visual inspection requirements.  These requirements are primarily described in Appendix A and Appendix B of ANSI/RESNET/ICC 301-2014 and 2019.

Projects

Projects working on for the 2022 edition of 301:

  • Inspection requirements related to framing factors
  • How to properly evaluate the presence of ‘advanced’ framing
  • Better guidance regarding duct insulation
  • Partnering with ASTM to develop an infrared (IR) insulation inspection standard
  • Adding inspection protocols and definitions that will be needed for use with the HVAC Grading Standard (under development now, BSR/RESNET/ACCA 310-20xx)
