To assist Energy Plus users
with modeling wall assemblies with Insulated Vinyl Siding, the attached idf
file contains material properties for light and medium/dark Insulated Vinyl
Siding at nominal R-value increments of 2.0, 2.5, and 3.0. Also included
are several dozen wood frame and steel frame composite wall constructions that
use insulated vinyl siding on the exterior layer. The constructions are
configured to be in compliance with the calculation methodologies outlined in
ASHRAE 90.1-2010 Normative Appendix A3, for metal and wood framed walls.
This file was developed by Newport Ventures with input from the Vinyl Siding
Institute and was vetted with Energy Plus support staff prior to its release.â??
Insulated Vinyl Siding is vinyl
siding with rigid foam insulation that is factory-laminated directly to the vinyl. In energy codes and energy efficiency programs, Insulated Vinyl Siding is
recognized as a form of â??continuous insulation,â?? which is insulation installed on
the exterior of the building that helps reduce energy loss through framing or
other building material. Within the
International Energy Conservation Code and ASHRAE
90.1, Insulated Vinyl Siding qualifies among the materials that can be used as continuous insulation to help
achieve the required whole wall U-factors
for buildings across all climate zones. Learn more about how Insulated Vinyl Siding
can meet the requirements of energy codes at http://www.vinylsiding.org/aboutsiding/insulated/energycode/index.asp.
