What is an energy efficiency rating?

An energy efficiency rating is a measurement that assesses how effectively a property converts energy into useful forms such as heating, lighting, and other applications. This score typically considers factors like insulation quality, heating and cooling systems, and overall energy consumption patterns to determine how efficiently a building uses energy resources.

Having a high energy efficiency rating indicates that a property performs well in utilizing energy, potentially leading to lower utility costs and a smaller environmental footprint. This rating serves as valuable information for both property owners and tenants, as it provides insights into expected energy consumption and costs associated with the property.

Other options do not correctly capture the essence of an energy efficiency rating. For example, a score indicating how expensive utility costs are focuses only on the cost rather than the effectiveness of energy usage. Similarly, a rating about a property's history would be irrelevant to energy efficiency, and a rating based on the age of appliances does not provide a comprehensive view of the property's overall energy performance.
