ICF effect

2 page PDF

“ The synergy of higher R-value, virtually no air infiltration and the added thermal mass in ICF assemblies result in performance that simply can’t be duplicated with traditional framed assemblies. ”

The “ICF Effect” on HVAC Design

2 page PDF

“ Walls built with ICFs can significantly reduce heating and cooling loads and affect HVAC equipment sizing. With ICF houses, the traditional HVAC sizing rule of thumb doesn’t work well, because it is based on assumptions of standard heating loads per square foot. ICFs fall outside of the norm. ”

Energy Use ICF wall compared to wood stud walls

49 page PDF

“ A typical 2,450 square-foot single-family house design was modeled for energy consumption in twenty-five cities (25 ASHRAE zones) across the US and Canada. Due to the thermal mass of the concrete walls, houses with concrete walls had lower heating and cooling costs than houses with frame walls, ... ”
