Guidelines for using the ENERGY STAR® Most Efficient mark

2016 Most Efficient

PDF version

The ENERGY STAR Most Efficient mark is an extension of the ENERGY STAR brand. It is designed to identify and promote the most efficient and innovative of ENERGY STAR certified products.

This document lays out the rules for using the Most Efficient mark correctly. It must be used as a supplement to the more comprehensive Guidelines for the application and reproduction of the ENERGY STAR® name and symbol in Canada.

Using the ENERGY STAR Most Efficient mark

1. As a visual identifier

The mark may be used as a visual identifier on product literature, point-of-purchase (PoP) displays, websites and other information or marketing materiel. Utilities and energy efficiency programs can also use the mark as a visual identifier to encourage consumers to look for the most energy-efficient products.

Correct use

  • Highlight a product that has been recognized as ENERGY STAR Most Efficient.
  • The mark may be resized, but the proportions must be maintained. For legibility in print, the ENERGY STAR symbol block within the mark is not to be reproduced smaller in width than 1.0 cm.
  • A clear space of 1/3 the height of the mark should surround the mark at all times. No other graphic elements, such as text or images, can appear in this area. This spacing is mandatory since the mark may appear within materials using complex imagery, such as other marks, graphic devices and text.
  • The mark should always appear in ENERGY STAR blue (100% cyan), whether on the Web or in print materials.

Incorrect use:

  • Do not use the mark or name in association with products that have not been recognized as ENERGY STAR Most Efficient, including products with applications pending.
  • Do not use the mark or name on products or product packaging.
  • Do not use the mark or name to denote ENERGY STAR partnership or endorsement.
  • Do not alter the lock up (relation of symbol to text) of the mark.
  • Do not rotate the mark.
  • Do not separate any of the mark’s elements.
  • Do not violate the clear space of the mark.
  • Do not display the mark in any colour other than ENERGY STAR blue (100% cyan).
  • Do not use the mark and/or name on non-product specific promotional materials, stationery (e.g., letterhead, business cards), buildings, homes or vehicles. 

2. In Text

When writing about products that are designated ENERGY STAR Most Efficient, please use the following language:

“Recognized as the Most Efficient of ENERGY STAR [YEAR]”.

This language can be used to highlight ENERGY STAR Most Efficient designated products on the Web and in print materials.

Example – preferred text on a retailer website
