EPS Green Building Credits

EPS foam insulation is a cost effective and extremely versatile building material that can be used in a variety of applications to achieve increased energy savings.

There are several green building programs in North America. A majority of the green building programs recognized in the U.S. and Canada have similar criteria for evaluating environmental attributes with two major considerations: material selection and long-term building performance.

EPS can contribute to achieving green building ratings in the following categories.

Energy & Atmosphere

EPS insulation facilitates compliance with ASHRAE 90.1-1999.

• EPS can be manufactured in a variety of densities and thicknesses to meet environmental design criteria to deliver a range of R-value specifications.

• EPS has always been CFC and HCFC free.

• EPS is the only rigid foam insulation that provides long-term thermal resistance that does not need to be adjusted for age.

• EPS building systems reduce air leakage for increased thermal efficiency.

Materials & Resources

• Recycled content EPS that meets ASTM C578 minimum performance properties can be specified for rigid foam insulation.

• Recycled content polystyrene can be specified when procuring plastic lumber, interior trim, lightweight concrete, asphalt aggregate and other building products.

• With hundreds of plant locations in North America, EPS is manufactured locally, minimizing its distribution radius. Because it is lightweight EPS reduces transportation costs and energy.

Indoor Environmental Quality (IEQ)

EPS is not known to adversely affect indoor air quality.

• EPS mold resistance tests favorably in accordance with ASTM C1338.

• EPS building systems can prevent noise transmission, resulting in quieter buildings.

• EPS insulation helps maintain a consistent air temperature.

Sustainable Sites

EPS insulation reduces impacts on the microclimate.

• EPS geofoam maintains ecological integrity and reduces erosions through soil stabilization.

• EPS frost protected shallow foundations (FPSF’s) minimize excavation below the frost line and are ideal for sites with high groundwater table.
