State Codes
With What Code Must
My Window Comply?
Two
web sites exist that will direct commercial and residential users
to the proper energy code for your location. First, click
on the Alliance to Save Energy's Building Code Assistance Project
web page:
Once there, click
on the United States map. Once that page is open, select
your state from the drop down menu in the middle of that page.
Read under the heading "Current State Codes" to determine
the proper code.
Next,
click on the Responsible Energy Code Allicances Web site.
Once
there, click on the image with a map under the heading, Interested
in determining the IECC® provisions as they would apply to
your state? Now choose the proper IECC year that the BCAP
web site indicated from the proper dropdown. An embedded
PDF will open showing a state map and a list of various U-factors
and SHGC. Find your county. It will be listed in a
table on that state's PDF image. The county will correspond
to a zone. Match the zone to the proper columns on the U-factor
and SHGC table. This is the required code level!
Exceptions
Some
states do now reference IECC codes. If your state does,
not list the code on the BCAP web page, read towards the bottom
of the web page under web links. These links will take you
to the state's code. Unfortunately, RECA nor any other authority
has extracted out the necessary codes for windows and walls.
You will have to read the code. Please call NFRC to ask
specific questions on your states codes.
