Enervee® Score

Enervee Score® improves how we choose for our homes.

Easy to understand

The Enervee Score translates product performance and energy usage into a clear 0-100 score.

Energy-smart choices

People choose more efficient products (12% more efficient TVs in one study) when the Enervee Score is present.

Long-term benefits

Super-efficient purchases unlock long-term energy savings across the lifetime of the product.

It all starts with a number

Delivering energy-smart choices

Calculated daily for all models across more than 20 product categories, the Enervee Score makes energy efficiency visible. For the first time, the market for efficiency is active; consumers can finally choose to make the most energy-smart decisions.

Calculating Enervee Score®

The higher the Enervee Score, the more efficient that product is, relative to all other relevant products in its category. Normalized across categories, the Enervee Score enables consumers to instantly see and understand the model-specific energy performances for any possible purchase. The Enervee Score is also reviewed and refreshed daily - for every product category. This means all product launches are shown within 24 hours, and no decision is ever made on old data.

The Enervee Score provides market transparency when it comes to product energy usage. And from September 2018, we’ve updated the methodology to calculate the Enervee Score to make it even easier - and clearer - for consumers to choose the most efficient models. Using the full range of the 0-100 scale, the Enervee Score maps every product with their specific score. All but the best 10% of products score between 0 and 90 on the Enervee Score scale, with specific bands for easy recognition: Low (0-50), Average (50-75) and Good (75-90). For the top 10% of products in each category, we reserve the Enervee Score range of 90-100. Top-performing products score 90-100 (IDEAL), making it easier still to pick the ideal products and appliances for your home. For products that are not better than 90% of the competition, improvements in Enervee Score are directly proportional to improvements in efficiency. In 2020, we updated the mathematics of the Score vs. efficiency calculation to make it represent a robust statistical average of Score vs. product rank for all products in the market.

Enervee follows the appropriate and accepted standards on performance and energy efficiency ratings in each territory where used. For categories that are not yet regulated by standards (e.g. video game consoles), Enervee collaborates with stakeholders to develop and agree on its own energy efficiency rating methodologies.
