2015 International Energy Conservation Code to include Energy Rating Index Compliance Option
Last week, the International Code Council (ICC) voted to incorporate an optional Energy Rating Index compliance path into the International Energy Conservation Code (IECC). As a result, a new voluntary performance compliance path for the 2015 version of the IECC the “Energy Rating Index” has been established. Those currently using the RESNET HERS Rating Index can use the score to comply with the 2015 code since it is deemed compatible. The adopted new performance path also requires that a builder must meet the mandatory envelope requirements of the 2009 IECC. The IECC rating scores are below.
Regions 1 and 2 52
Region 3 51
Region 4 54
Region 5 55
Region 6 54
Region 7 and 8 53
It is believed that homes that comply with this new path will be higher performing hence having lower utility bills while at the same time provides more flexibility to builders in meeting the code. Icynene recommends having a HERS Rater assess your designs and homes to build green and more energy efficient homes.
