The following is a link to a suggested format for showing compliance with the 2012 IECC on the construction documents.  Since compliance for commercial projects must be with the 2012 IECC in its entirety or Standard 90.1-2010 in its entirety, there are four spreadsheets shown on the AIA Connecticut web page.

For those interested in how the requirements of Standard 90.1 have changed, the following spreadsheets show the progression of the requirements.
