Energy Ratings – Important Details Consumers Should Know About Energy Efficiency
Energy ratings for appliances have been changing over the last few years and you may notice this when you shop for an energy star appliance, blender, oven, food processor, flat-pack coffee maker, washer/dryer, or dishwasher. When you first shop for an energy star appliance, you’ll see that there are several top categories and then F and O which are very close in price. At first glance, all appliances look the same, but beneath the surface, they are all different. How appliances are rated will depend on their energy usage and the way the energy usage is measured. Appliances are usually rated in kilowatts (kW), cubic feet per minute (CPM), or electricity used, and in Fahrenheit.
One category of appliance
What has changed a lot over the past couple of years is the refrigerator and under-door freezer. In the past, an under-door freezer was rated based on its capacity in terms of the number of food items it could hold. Now, the energy ratings take into account how many food items the refrigerator can hold and how cold the food needs to be before it needs to be thawed. Under-door freezers now rank lower than the top-rated refrigerators because they don’t keep as much cold as the others do, even though some of them are small and compact.
Another big change is in the rating system for appliances.
Once the energy consumption is measured, the label goes to an annual energy consumption rating. The labels also specify the manufacturer of the equipment. Some manufacturers, such as Amana, are committed to improving their energy ratings. They work with the energy efficiency programs of utilities and government agencies to reduce energy consumption in their products.
Other companies, such as GE, rely on their ranking system.
The GE energy ratings are based on three factors: the physical size of the equipment, its performance, and its environmental performance. This system rates green energy-efficient appliances as low, medium, or high energy efficiency. The GE system assigns a score that ranges from zero to nine for each category.
The Energy Star labeling system is a little more complicated.
It divides the major appliances into two categories. The first category is for major appliances, such as stoves, dishwashers, refrigerators, and washing machines; and the second category is for less important appliances, such as wall heaters and microwave ovens.
To get energy efficiency ratings for your home
visit Energy Star. The Department of Energy (DOE) provides support and information for energy star ratings and rating systems. You can also visit the DoE website to learn more about Energy Star rating systems. In addition, Energy Star ratings are often referenced in real estates marketing materials, such as brochures and advertisements. Some real estate agents use these ratings as a tool to help homeowners select appliances.
