What is an ERI Score?

The Energy Rating Index (ERI) score is designed to quantify a home's overall energy performance. It provides a numerical value that reflects how energy-efficient a home is compared to a baseline. A lower ERI score indicates a more energy-efficient home, while a higher score reveals higher energy consumption. This score encompasses various factors, including insulation levels, lighting, and the efficiency of appliances, which all come together to form a comprehensive picture of a home’s energy use.

This approach allows prospective home buyers, builders, and energy raters to assess and compare the energy efficiency of different homes. It aids in promoting energy-efficient building practices and renovations by providing a clear, standardized measure of energy performance, which can influence consumer decisions and policy regulations. Thus, option B accurately captures the essence and purpose of the ERI score in the context of home energy ratings.
