This approach means that compliance software maynot be as critical in handling building energy performance. Purpose is to simplify and clarify code compliance withIECC, Model Energy Code and several state codes Offers both trade-off and prescriptive approaches todemonstrate compliance Residential code compliance and rating software developedspecifically for Home Energy Rating System providers75 For more information, please see http://www.ibec.or.jp/CASBEE/english/index.htm.85
