(#8426) Duct location to be considered for ductwork insulation.


Referring to the table provided under the ECBC 2007, the selection of ductwork insulation is considered based on the duct location.

In case, the supply & return duct are located above the false ceiling & the height between the false ceiling & true ceiling is 6 feet,which duct location (ventilated attic, unconditioned space, indirectly conditioned space, etc) from the table 5.2.4. needs to be considered for ductwork insulation?


The project team has to consider the duct under Unconditioned Space for documentation purposes.
