The Enervee Score helps you to find the most energy efficient brands by translating product performance and energy use into a universal 0 to 100 score broken down into four energy usage levels: not good (0 to 50), good (51 to 75), very good (76 to 90) and ideal (91 to 100). The higher the Enervee Score, the more energy efficient and therefore less energy a product uses for its size/capacity/performance.
The Enervee Score is dynamic, meaning that it is updated daily for all brands based on the range of brands and models currently available on the Power Smart Shop site and seamlessly integrated with the product listing to enable sorting or filtering on energy efficiency, cost, and other features.
Calculating the Enervee Score
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 that are available and currently listed on the Power Smart Shop site. The following information is used to calculate the Enervee Score for each product category:
• 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
• Video Game Consoles: performance (CPU speed, memory and hard drive capacity) and kWh/yr
• Air Conditioners: BTUs of cooling power per watt
• Monitors: screen size (diagonal in) and kWh/yr
Enervee follows industry standards on performance and energy efficiency ratings from the US Department of Energy. For categories that are not regulated by the DOE, such as video game consoles, Enervee has collaborated with key stakeholders to develop appropriate energy efficiency rating methodologies.
