Code Adoption & Change Process

Process Type: Regulatory

Code Change Process: The New Hampshire Building Code Review Board has the authority to change the standards within the code. The procedure consists of public hearings held by the Review Board followed by public adoption or rejection of proposed amendments. The NH General Court must concur with any amendments adopted by the Board within two years or the code reverts to the prior version. The IECC 2006 was adopted by the General Court in SB 81 and enshrined in RSA 155-A:1(IV). See Chapter 155-A of the New Hampshire Building Code.

The New Hampshire Public Utilities Commission administers the code by developing the code review process, approving applications, providing technical assistance and coordinating training.

State Code History: The original energy code for New Hampshire was enacted in response to PL-94-163. This enabling legislation was RSA 155:D, which applied to both residential and commercial buildings and was based on ASHRAE/IES Standard 90-75 and the National Conference of States on Building Codes and Standards "Code for Energy Conservation in New Building Construction" dated December 1977. RSA 155:C, which related to energy conservation in state-owned buildings, was later repealed. The residential standards and administrative sections of RSA 155:D were revised in 1986. The standards for commercial buildings were revised in 1993 to reflect the EPAct requirement for compliance with ASHRAE/IESNA 90.1-1989. In 1998, MEC95 standards were adopted. The Building Code Review Board and the General Court adopted the IECC 2000 in 2002.

Currently, New Hampshire has adopted the 2006 IECC Zone 6 as its residential and commercial energy codes.
