Sunrise Home Achieves High Performance Specs

In 2013 the Sunrise spec home was completed. When tested, the home scored a HERS rating of 55, the lowest level that the Duke Energy Progress program recognizes. Additional testing showed that the duct leakage measured zero leakage, versus 4% allowable under the testing program. The blower door test allowed up to 4 air changes per hour; the tested results for the house showed only 2.7 air changes per hour, a full 30% better performance than necessary.
