According to the project architect, ICFs were specified on this project quite simply for stewardship reasons including reducing materials, labor and energy usage. Using ARXX ICFs for the building envelope helped reduce the size of HVAC equipment required. This move was also encouraged by a recent law in North Carolina which requires all state-funded building designs over 20,000 sq ft. to undergo Life Cycle Cost Analysis. The purpose of the law is to ensure that such buildings exceed ASHRAE 90.1 2004 energy efficiency standards by 20% for buildings constructed through calendar year 2010, and 30% through calendar year 2015. When completed, this project will also be LEED Silver certified.
