Description
The 2015 IECC contains many important changes including:
Overall energy conservation levels of the 2012 IECC are maintained while at the same time an alternative path for residential energy compliance which provides greater flexibility which is likely to lower construction costs has been added. It is called the Energy Rating Index Compliance Alternative. (Section R406; RE188-13)
Two new chapters for existing buildings which are undergoing repairs, alterations or changes of occupancy have been added for both residential and commercial buildings. (Chapters C5 and R5; CE4-13)
