Energy efficiency is the core feature of insulating concrete form construction because so many owner/occupant benefits stem from it. Actual studies show that homes built with ICF exterior walls require an estimated
44% less energy to heat and
32% less energy to cool than comparable wood frame houses. ICF homes are more than 6 times more energy efficient than concrete block homes.

However, homes and structures built with the proper complement of windows, doors, HVAC systems, and methods, generally accomplish at least a
50% savings in heating and cooling. In some cases, depending on the area and climate, homeowners experience as much as an 80% decrease in energy use and costs.
At a time when energy costs are soaring, many building owners are deciding to spend money on a safer, longer lasting, and more energy efficient structure than to spend that same money on utility bills.
