The Enervee Score® is calculated based on how much more or less energy a product uses compared to all others of the same size/capacity/performance. Below are key attributes used for calculating the Enervee Score for each product category:
- Televisions: screen size (diagonal in) and kWh/yr
- Refrigerators: capacity (ft3) and kWh/yr
- Freezers: capacity (ft3) and kWh/yr
- Projectors: lumens of brightness and kWh/yr
- Clothes Washers: cubic feet of volume per kWh per cycle
- Dishwashers: cycles per kWh
- Clothes Dryers: pounds of clothes per kWh
- Tablets: performance (screen size & pixels, processing power and battery life) and kWh/yr
- Air Conditioners: BTUs of cooling power per watt
- Monitors: screen size (diagonal in) and kWh/yr
- Light Bulbs: lumens of brightness and watts
Enervee follows industry standards on performance and energy efficiency ratings from the Department of Energy. For categories that are not regulated by the DOE, such as tablets, Enervee has collaborated with key stakeholders to develop our own energy efficiency rating methodologies.
