Energy Code Compliance in Indiana & Kentucky

We provide energy code compliance verification services by doing HERS Ratings for new residential buildings in Indiana and Kentucky. As of April 5, 2012 all new construction residential buildings must comply with the new energy code in Indiana, which is based upon the 2009 IECC.  Kentucky also adopted this new energy code in October of 2012.

There are three methods, or "paths", available that builders can choose to use to pass the new code requirements.  

These three paths include:

  1. Prescriptive Path
  2. Total UA Alternative Path
  3. Performance Path (HERS Rater)

Most builders will find that the "Performance Path" will be the most cost-effective to choose, especially in Climate Zone 5.

More on the 2012 Indiana & Kentucky Energy Code

The 2012 Code is based on the 2009 IECC (International Energy Conservation Code), which requires blower door testing and duct-blaster testing, when choosing the "performance path" compliance method.

New homes built in Indiana also have two climate zones as defined in the 2009 IECC.  The new energy code requirements differ slightly depending on the climate zone the home is built in, either Zone 4 or Zone 5.

The main difference with the new code requirements in each Climate Zone is the amount of insulation needed in above grade walls.  

Prescriptively, Climate Zone 5 requires a minimum R18 or higher wall assembly, versus R13 for Climate Zone 4.  However, some homes may not need the R18+ insulation if the Performance Path is chosen for code compliance. 

This must be verified by using energy-modeling software, such as Rem/Rate, Rem/Design, or EnergyGauge, by an independent third-party.  Only a trained building-science professional, such as a HERS Rater, can perform this task.

When a builder chooses the "Performance Path" to comply with the new code, a HERS Rater is involved and projected energy modeling is done based on the building plans and specs, and the software will state whether or not the plan will pass the new code requirements. 

Different "build scenarios" can be run in the software to easily determine the most cost-effective ways for new homes to comply.
