JKP Energy Inspections provides support services for residential home builders in navigating Energy Code Compliance (IECC) including:
Support services include:
As soon as you have city approved plans (including mechanical) call us and we will let you know what to do!!
We prefer to have you call BEFORE you start construction.
Arizona does not have a statewide code year. Instead, each city picks the year that they comply with. They can also add amendments.
City of Phoenix - 2018 IECC
City of Scottsdale - 2015 IECC
For other details, visit each city website.
Chapter 4 Residential Energy Effiency of the IECC code explains everything you need to know!
Per section R401.2 of the IECC code:
Projects shall comply with one of the following:
1. Sections R401 through R404 - Prescriptive Path
2. Section R405 and the provisions of Sections R401 through R404 labeled "Mandatory." - Performance Path
3. An energy rating index (ERI) approach in Section R406.
Establishes criteria for compliance using simulated energy performance analysis. Such analysis shall include heating, cooling and service water heating energy only. The "Mandatory" sections must also be followed.
Per Section R405.3:
Compliance based on simulated energy performance requires that a proposed residence (proposed design) be shown to have an annual energy cost that is less than or equal to the annual energy cost of the standard reference design. Energy prices shall be taken from a source approved by the code official, such as the Department of Energy, Energy Information Administration's State Energy Price and Expenditure Report. Code officials shall be permitted to require time-of-use pricing in energy cost calculations.
Exception: The energy use based on source energy expressed in Btu or Btu per square foot of conditioned floor area shall be permitted to be substituted for the energy cost. The source energy multiplier for electricity shall be 3.16. The source energy multiplier for fuels other than electricity shall be 1.1.
Only if you are following the Prescriptive Path. If you are using the Performance Path, other energy efficiency specs can be used as trade-outs.
If you follow the Performance Path and have us complete an Energy Simulation on your project, you will receive an IECC Certificate from our software that shows compliance. For Examples, see below:
