The following is a spreadsheet that compares the energy code requirements of the of the 2005 State Building Code (2009 IECC) to the energy code requirements of the 2016 Connecticut State Building Code (2012 IECC).  The 2012 IECC has two compliance paths for commercial buildings, the requirements in the 2012 IECC or the requirements of Standard 90.1-2010.  The requirements for both are shown on the spreadsheet.

The following is a link to a suggested format for showing compliance with the 2009 IECC on the construction documents.  Since compliance for commercial projects must be with the 2009 IECC in its entirety or Standard 90.1-2007 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.
Standard 90.1-2001, -2004, -2007 Requirements

Standard 90.1-2004, -2007, -2010 Requirements
