Commercial

The International Energy Conservation Code 2009 (IECC 2009) became effective in New Hampshire April 1, 2010. See  http://www.nh.gov/safety/boardsandcommissions/bldgcode/nhstatebldgcode.html
Note: Town of Durham ordinance #2011-02 requires compliance with Climate Zone 6 provisions.
An application form (EC-1) for residences and commercial structures under 4000 square feet is available for download on the code Residential Energy Code Application (EC-1 Form) page.
If you wish to use the software approach to prove compliance of commercial structures with the code you should download the latest version of COMcheck Software. Click here to download COMcheck. Click on Code on the toolbar and set to 2009 IECC.

Then set the State to New Hampshire and City to the municipality where the project is planned.  For construction planned in Durham, set the City to “Concord”.

NOTE: The code divides the State of New Hampshire into two climate zones so there will be differences in requirements between the four southern counties and all others.


The Public Utilities Commission does not issue commercial energy code permits for structures of 4,000 sq. ft. or larger.  Small commercial structures under 4,000 sq. ft. may use the residential energy code Residential Energy Code Application (EC-1 Form)  to demonstrate envelope compliance.
