Re: Kagan Residence
Dear Bryan & Adam,
This document is intended to show compliance of the remodel of the Kagan Residence at Units 3A & 3B
of 520 E Hyman Ave, Aspen, CO with the 2015 International Energy Conservation Code (2015 IECC). We
propose to use a prescriptive approach per sections R402.1-R402.3 and R403.2.1 of the 2015 IECC.
Project
The project at 520 E Hyman Ave is a remodel of the existing penthouse apartment with a floor area of
2,915 sf. For heat load calculations, please refer to the Appendix. The heat load calculations are
performed using the Carrier Hourly Analysis Program and provides a more detailed and accurate load
than Manual J.
Building Envelope
The following table lists the mandatory minimum insulation and fenestration requirements for the project
climate zone (7). All new assemblies will meet the following requirements.

Notes: 1) Fenestration SHGC requirements do not apply in climate zone (7)
2) First value is cavity insulation, second value is continuous insulation
3) Or insulation sufficient to fill the framing cavity, R-19 minimum
4) R-15 continuous insulation on the interior or exterior, or R-19 cavity insulation on the interior
of the basement wall. Can be satisfied with R-13 cavity plus R-5 continuous
5) 4 ft deep and R-15 edge insulation for heated slabs
Sincerely,
Alex Timberlake
