 BPI has corrected the example shown under the
Distribution Efficiency Look-up Table on page 7 of the
Technical Standards for Heating. The previous
example listed 91% as the last reference number. The number
should read 94%.
Example: If you have a
system with more than 90% inside the conditioned space
(ie. in a heated basement) and the system is sealed
with mastic and the portion of the duct system that is
not in the heated space has an R-value of R-4, the
distribution efficiency of the system is 94%. To

and click on the BPI Standards link or click here. | |
