The New Mexico Construction Industries Licensing Act of 1978 established requirements for all building trades contractors to be licensed and certified to ensure that compliance with the state codes is, to the maximum extent possible, uniform in application, procedure, and enforcement. This Act has been updated periodically since 1978. The state energy code contains statewide mandatory minimum requirements that local jurisdictions must adopt and enforce.
In 2004, New Mexico passed a bill establishing a tax credit for green homes. In order to qualify, homes had to achieve a HERS rating of 60, which means that it will have to be 40 percent more energy efficient than a reference home built according to code. Additionally, a qualified home had to achieve either a LEED for Homes Silver certification or a Build Green NM Gold certification. The tax credit amount depended on the home's energy performance and sustainability rating.
The Construction Industries Division adopted the 2003 International Energy Conservation Code (IECC) with an effective date of July 1, 2004.
On January 1, 2008, the 2006 NMECC, based on the 2006 IECC with New Mexico amendments, went into effect with a six-month grace period to use either the new code or previous state code. Commercial buildings were exempt and subject to ASHRAE 90.1-2004.
Most Recent Update: On June 10, 2011, the Construction Industries Commission repealed the original version 2009 New Mexico Energy Conservation Code (NMECC) and other construction codes the Commission adopted in 2010 after months of work by the Construction Industries Division (CID) to develop them:
- CIC had originally adopted a 2009 NMECC version containing strengthening amendments to the 2009 IECC that achieved greater energy savings, roughly 20% beyond the 2006 IECC.
- In early 2011, the NMECC was subject to administrative rollback attempts and an ultimately successful advocate legal challenge. The state spent several months conducting activities to implement the advanced code beginning July 1, 2011, including training in 14 cities and providing free codebooks through PNNL and ICC.
- On April 22, 2011, the Commission gave initial approval to proposed changes to the NMECC that would revert the code back to the base 2009 IECC code. CID held public comment hearings around the state on June 2 and gave final approval to the code rollback on June 10, 2011.
- The previous version of the NMECC – based on the 2006 IECC – went back in effect for nearly six month until the revised version set at the 2009 IECC baseline took effect in January 2012.
- On July 11, 2011, SWEEP and other parties filed an appeal asking the New Mexico Court of Appeals to reverse the Commission’s June 10 decision to repeal the advanced 2009 NMECC and other construction codes.
