Saving Energy is the world's top priority. The building sector accounts for 50% of America's energy use, in the heating and cooling of the building. ICF walls can make a difference to the thermal envelope due to the combined effect of the continuous R-Value, the airtight construction and thermal mass mitigation. Read more about the The ICF Effect
ICFs are made from Expanded Polystyrene(EPS), which was developed as a use for a waste-stream product in the development of oil. In other words, it was originally considered post-industrial recycled material. The styrene resins are transported to the local molding plant, where they are expanded to 28 times their size with the use of only air and moisture. And to top this off, EPS R-value does not diminish over time, saving many barrels of oil and tons of coal with the greatly reduced heating and cooling requirements. Now that's an effective use of material.
LEED Points to ICF
ICF construction can significnatly contribute to USGBC LEED Energy Optimization credits… the toughest points with the greatest savings in life cycle costs.the US Green Building Council Leadership in Energy and Environmental Design (LEED) Green Building Rating System. LEED promotes a whole-building approach with performance criteria in five areas: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality."ICF Points to LEED."
