The publication of the 2012 International Energy Conservation Code® and ANSI/ASHRAE/IES Standard 90.1-2010 Energy Standard for Buildings Except Low-Rise Residential Buildings, in one book, is another positive step forward in the efforts of the International Code Council® (ICC®) and the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to increase the awareness about and application of energy-efficient buildings and to provide the latest and state of the art energy efficiency requirements in one place.
