What is the average HERS Index score for newly built homes?

The average HERS Index score for newly built homes typically falls within the range of 60 to 70. The HERS Index measures a home's energy efficiency, with a lower score indicating greater energy efficiency relative to a reference home, which has a HERS score of 100. Newly constructed homes that are designed with energy-efficient features, such as improved insulation, energy-efficient appliances, and advanced HVAC systems, often achieve scores in this range due to stricter building codes and a growing emphasis on sustainable building practices.

This average score reflects advancements in energy efficiency technologies and practices that have become more common in new construction, allowing these homes to perform significantly better than older homes, which often fall into higher score ranges.
