Enervee Score®

Making energy efficiency 

Product cards

It all starts with a number.

The Enervee Score® changes how we make purchases for our homes, delivering consistently more energy-smart choices. It does this by translating product performance and energy usage into a clear 0-100 score.

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.

The Enervee Score® improves how we choose for our homes.

The Enervee Score® effect is seen consistently across product categories, consumer types and buying conditions.

When using IDEAL Marketplace, in-market shoppers' choices are typically both more efficient and better priced than the market average, often outperforming even those products with rebates attached.

People choose more efficient products (here, 12% more efficient TVs) when the Enervee Score® is present.

One-time behavior change. 
Long-term benefits.

By affecting one-time buying decisions, the Enervee Score® unlocks long-term energy savings across the lifetime of the purchase, thanks to it being super-efficient in the first place.

Calculating the Enervee Score®

The higher the Enervee Score®, the more efficient that product is, relative to other relevant products in its category. Normalized across categories, the Enervee Score® enables consumers to instantly see the true energy performances of their possible purchases. The Enervee Score® is also updated daily for all products across every category on the IDEAL Marketplace, meaning any product launches are shown within 24 hours.

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