Fact Sheets

The following fact sheets have been developed to support commercial provisions of the Idaho Energy Code. 


Additional Efficiency Options of the 2012 IECC Fact Sheet

Section C406, Additional Efficiency Package Options, is a new provision in the 2012 IECC that requires a project to comply with one of three options:

  • More efficient HVAC equipment
  • More efficient lighting systems
  • Addition of a renewable energy system

The provision is intended to give commercial building designers and owners flexibility when achieving additional energy efficiency.

Daylighting Requirements of the 2012 IECC

The 2012 IECC includes provisions for commercial buildings to employ daylighting in project design and construction. Daylighting is the controlled admission of natural light into a building to reduce the use of electric lighting and save energy. Daylighting is achieved through the use of windows, skylights, and other fenestration, and by utilizing daylighting controls. Daylighting controls reduce electric lighting by dimming or turning off lights in response to sunlight coming in through windows and skylights.


NFRC Certification for Site-Built Commercial Fenestration

The 2012 IECC specifies maximum permitted U-factors, solar heat gain coefficients, visible transmittance, and air leakage for fenestration. The requirements apply to all fenestration assemblies, including windows, doors, skylights, and curtain walls. To verify that the fenestration meets the requirements of the IECC and is NFRC-certified, a National Fenestration Rating Council (NFRC) label must be affixed to the assembly.
