Energy rating scale

The energy rating scale is a way to show how energy-efficient a home, appliance, or building is, typically on a letter or number scale. For homes, for example, a higher rating (like A or 5 stars) indicates better energy efficiency, meaning lower energy use and costs. Conversely, a lower rating (like G or 1 star) suggests the property consumes more energy, often resulting in higher bills and a larger environmental impact. This scale helps consumers compare options quickly and encourages improvements in energy performance for cost savings and sustainability.
