State of Illinois Adopts Energy Rating Index Compliance Option to State Energy Code

Jan 7, 2016

On January 1, 2016 the State of Illinois joined the ranks of states that have adopted the 2015 International Energy Conservation Code (IECC).  Included with the adoption is the Energy Rating Index compliance option (R406).

The required Energy Rating Index scores in Illinois that must be met are:

Climate Zone 4                                   54 or lower

Climate Zone 5                                   55 or lower

The Energy Rating Index scores required in the state are contained in Section R406 of the 2015 IECC.

The new state energy code went into effect on January 1, 2016.
