BAI Project 7010
Dear Brendan:
Pursuant the round 2 City of Aspen Building Department comments on the subject project, following are
responses to the items within our purview.
Page A501 (Zone 4 item#4):
We have re-run the REScheck to account for the R-47 cavity insulation. The revised run has
accounted for the tapered insulation noted on the architectural details by adding an R-15 continuous
layer within the calculation. The revised REScheck calculation has been attached to the email with
this letter.
Page M101 (Zone 4 item#6):
The balanced system requirement has been accounted for by the addition of a heat recovery
ventilator to the design. The HRV, associated ductwork, and specifications has been shown on
Drawings M102, M103 and M105. The full updated mechanical plan package has been attached to
the email with this letter.
If you or the reviewer's have further questions or comments regarding any of the above information, please
don't hesitate to call or email.
Sincerely,
BU GG - F A SOCIATES INC.
