What does the acronym HERS stand for in building performance?

HERS stands for Home Energy Rating System, which is a widely recognized method for measuring a home's energy efficiency. It provides a standardized way to assess the energy performance of residential properties. The HERS index is an important tool used by energy auditors and rating agencies to evaluate how well a home performs compared to a reference home built to the 2006 International Energy Conservation Code (IECC).

The HERS rating helps homeowners identify ways to improve energy efficiency, leading to potential cost savings on energy bills and a reduction in greenhouse gas emissions. A lower HERS score indicates a more energy-efficient home, whereas a higher score suggests higher energy consumption. This system is significant in the context of building performance as it promotes energy-conscious decisions in home design, renovation, and purchasing.

Other options do not accurately reflect established terminology related to home energy performance. For example, Heating Efficiency Rating Standards may suggest a specific focus on heating systems rather than overall home energy use, which is limited in scope compared to HERS. Similarly, Home Environmental Research Studies and Home Energy Resource Solutions do not capture the same focused assessment framework that HERS provides for evaluating residential energy efficiency in a standardized way.
