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 90.1-2004.
-
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.
