ICF conducted the study on behalf of the North American Insulation Manufacturers Association (NAIMA) and the Polyisocyanurate Insulation Manufacturers Association (PIMA). Simulating the annual energy consumption of single-family homes, ICF tested homes configured with one of four wall insulation scenarios using a combination of common insulation materials that either met or exceeded the proposed code requirements. This data was then compared with homes designed with insulation that falls short of the 2004 IECC.
"The ICF study conclusively demonstrates the value of the 2004 IECC," said Charles Cottrell, vice president, technical services for NAIMA. "The updated codes are a necessary step towards energy conservation since so many homes and buildings are built to the minimum code requirements. The increased levels of insulation represent sound building practice."
