The governor signs House Bill 316, adopting the 2015 IECC for commercial and residential construction.

Utah Governor Gary Herbert issues the Utah Energy Efficiency and Conservation Plan. The plan includes 26 recommendations that highlight the existing energy efficiency and conservation efforts of both the state and utilities operating in it, including regulated investor owned utilities, municipal utilities, and rural electric cooperatives. The report includes guiding principles, a section with definitions and a basic overview of energy efficiency and conservation, as well as a section which details current consumption levels and characterizes energy efficiency as a resource. The plan also highlights the links between energy efficiency, water conservation, pollution reduction and air quality in Utah. SWEEP and its partner Utah Clean Energy participated in the development of the plan.
|February 29, 2012||
House Bill 262, which would have updated the residential code to the 2009 IECC, is tabled by the House Political Subdivisions Committee, indefinitely postponing action during the general session. This bill is eventually defeated in the House.
Several Utah media sources pick up pieces on building energy efficiency and the movement to update the state’s residential building energy code to the 2009 IECC:
|February 3, 2011||
The Utah House declines to amend a construction codes bill (HB 203) to adopt the 2009 IECC for residential dwellings. The Utah Senate Business and Labor Committee also chooses not to amend the bill. The panel does, however, resolve to study the issue more closely during the upcoming interim legislative session from April to October.
|October 20, 2010||
The Utah Senate Business and Labor Interim Committee chooses not to follow the recommendations of the Utah Uniform Building Code Commission to adopt a modified version of the 2009 IECC for new homes and major residential renovations, keeping Utah’s energy conservation code for one- and two-family dwellings at the 2006 IECC.
The committee considered five proposed amendments to add to a bill to be introduced in the next legislative session that would amend the state construction code. The committee chose to add the first two items not related to energy, but declined to add the three related to energy. Besides adopting the 2009 IECC, the other amendments respectively related to log homes and would have allowed conventional homes to use the performance path to show compliance by demonstrating 12% energy savings beyond the 2006 IECC, in addition to meeting all of the mandatory requirements of the 2009 IECC. The intended effective date would have been January 1, 2012.
Estimates of homeowner utility savings from the 2009 IECC range from $175 to almost $250 per year.
|September 8, 2010||
The Utah Uniform Building Code Commission holds a public comment hearing and votes unanimously to recommend the adoption of a modified version of the 2009 IECC for new homes and major residential renovations. The proposed Utah code would allow homes using the performance path to show compliance by demonstrating 12% energy savings beyond the 2006 IECC.
|July 1, 2010||
After the passage of the State Construction Code Adoption Act, the Utah Legislature updated the Utah State Construction Code to reference the 2009 ICC codes series, including the 2009 IECC. The residential provisions of the Utah State Construction Code are based on the 2009 IRC with Utah amendments, but the energy efficiency section (Chapter 11) of the 2009 IRC is replaced with Chapter 11 of the 2006 IRC and Chapter 4 of the 2006 IECC.
House Bill 394, amending provisions relating to the Uniform Building Code Commission, is introduced. It eventually fails in the House.
|January 1, 2007||
Updates to the Utah Uniform Building Standard Act, passed on January 1, 2006, go into effect. These updates make the 2006 IECC mandatory for all residential and commercial buildings.
|May 1, 2006||
House Bill 80, concerning energy savings in state buildings, goes into effect.

A bill is passed that provides for the adoption of an energy conservation code for state buildings, suggested voluntary compliance by the state’s political subdivisions, and recommended voluntary compliance by the state’s building industry.
The Utah Uniform Building Standards Act is passed.
