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.*  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. And 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 it makes more sense to spend money on a safer, longer lasting, and more energy efficient structure than to spend that same money on utility bills.
