The prerequisites are met and the credits are earned by achieving improvements in energy efficiency beyond what is required by code. The higher the level of energy efficiency achieved, the more points are earned. Performance is determined based on energy simulation and, in Homes, by performance testing (including blower door testing and EPA Thermal Bypass Inspection). Spray Polyurethane Foam can contribute to projects’ achievement of high levels of energy efficiency using assessment methods, because of the R-value per inch and the air sealing performance characteristics of foam.
