The new energy codes become effective. The residential code is based on the 2012 IECC with Nevada amendments. The commercial code is based on the 2012 IECC with Nevada amendments with ASHRAE Standard 90.1-2010 as an acceptable compliance path through Chapter 5 of the 2012 IECC. Local jurisdictions may not adopt less efficient energy codes

The Nevada State Energy Office (NSOE) adopts the 2012 IECC.

NSOE adopts final regulations (LCB File No. R024-11). These regulations will become effective July 1, 2012.

The 2009 IECC with amendments becomes effective in the city of Las Vegas.

The Nevada Renewable Energy and Energy Efficiency Authority (REEEA) hosts a workshop to accept written and oral public comments on the state’s rulemaking process to adopt the 2009 IECC as required under NRS 701.220. Three regulation hearings are scheduled for the summer around the state.

The Las Vegas City Council adopts the SNBO amendments to the 2009 IECC.

The Nevada Renewable Energy and Energy Efficiency Authority (REEEA) holds stakeholder meetings on January 11th in Reno and January 12th in Las Vegas to provide building jurisdiction, building professional and interested parties an opportunity to work with REEEA to develop the process for meeting 90% compliance with the 2009 IECC by 2017.

REEEA opens a rulemaking to adopt, amend, or repeal regulations to update the state energy code to the 2009 IECC. The Nevada Energy Commissioner must conduct at least three hearings on proposed regulations in different locations in the state and give 30 days notice for each hearing.

The Southern Nevada Building Officials approve the 2009 Amendments for Southern Nevada for use within its eight member jurisdictions, including Las Vegas and the surrounding areas.

Governor Jim Gibbons signs into law legislation (SB 73 and SB 358) that revises the process of updating the state’s building energy codes by establishing the standards adopted by the NSOE as the minimum standards for building energy efficiency and conservation. The law requires local governments to adopt the codes set by the Office of Energy and to enforce them (they are also allowed to adopt more stringent standards provided they give notice to the Office of Energy). The law mandates the adoption of the most recent version of the IECC and requires the adoption of the most recent updated version of the IECC every three years. The Office of Energy must still hold public hearings in three different locations in the state after giving 30 days’ notice of such hearings before adopting any new standards.

The 2003 IECC becomes mandatory for all jurisdictions that did not have an energy code in effect by the beginning of 2005, when Nevada Chapter 701 was passed. REScheck and COMcheck can be used to show compliance for the envelope and mechanical only.

The Nevada Office of Community Services is dissolved.

Nevada adopts the “Regulations for the Conservation of Energy in New Building Construction”, formulated based on the 1986 MEC with minor state amendments. This code is applicable only in areas where the local jurisdiction has not previously adopted an energy code. This remains the basis for the statewide energy code.

The legislature gives the Nevada Office of Community Services authority to formulate new statewide standards for energy conservation in new buildings.

The Nevada Department of Energy is disbanded. Between 1983 and 1986, the state does not support or enforce the energy code.

Nevada’s first energy code, “Energy Conservation Standards for New Building Construction,” is adopted. This code, based on ASHRAE Standard 90-75, was written by the state and formulated by the Nevada Department of Energy. All cities and counties are required to enforce the energy code requirements.
