C403.11.1 Duct and Plenum Insulation and Sealing (Mandatory)

2020 Energy Conservation Code of NYS > 4 [CE] Commercial Energy Efficiency > C403 Building Mechanical Systems > C403.11 Construction of HVAC System Elements (Mandatory) > C403.11.1 Duct and Plenum Insulation and Sealing (Mandatory)
JUMP TO FULL CODE CHAPTER

Supply and return air ducts and plenums shall be insulated with not less than R-6 insulation where located in unconditioned spaces and where located outside the building with not less than R-8 insulation in Climate Zones 1 through 4 and not less than R-12 insulation in Climate Zones 5 through 8. Where located within a building envelope assembly, the duct or plenum shall be separated from the building exterior or unconditioned or exempt spaces by not less than R-8 insulation in Climate Zones 1 through 4 and not less than R-12 insulation in Climate Zones 5 through 8.

Exceptions:

  1. Where located within equipment.
  2. Where the design temperature difference between the interior and exterior of the duct or plenum is not greater than 15°F (8°C).

Ducts, air handlers and filter boxes shall be sealed. Joints and seams shall comply with Section 603.9 of the Mechanical Code of New York State.
