Performance for Special Distinction
In order to receive additional recognition and/or support from EPA for its efforts within the Partnership, the
ENERGY STAR Partner may consider the following voluntary measures, and should keep EPA informedon the progress of these efforts:
Provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increaseavailability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR and
its message.

Consider energy efficiency improvements in company facilities and pursue benchmarking buildings
through the ENERGY STAR Buildings program.



Purchase ENERGY STAR qualified products. Revise the company purchasing or procurement
specifications to include ENERGY STAR. Provide procurement officials’ contact information to EPA
for periodic updates and coordination. Circulate general ENERGY STAR qualified product information
to employees for use when purchasing products for their homes.



Feature the ENERGY STAR mark(s) on Partner website and other promotional materials. If
information concerning ENERGY STAR is provided on the Partner website as specified by the
ENERGY STAR Web Linking Policy (available in the Partner Resources section of the ENERGYSTAR website), EPA may provide links where appropriate to the Partner website.

Ensure the power management feature is enabled on all ENERGY STAR qualified displays andcomputers in use in company facilities, particularly upon installation and after service is performed.

Provide general information about the ENERGY STAR program to employees whose jobs are
relevant to the development, marketing, sales, and service of current ENERGY STAR qualified
products.

Provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond theprogram requirements listed above. By doing so, EPA may be able to coordinate, and communicate
Partner’s activities, provide an EPA representative, or include news about the event in the ENERGYSTAR newsletter, on the ENERGY STAR website, etc. The plan may be as simple as providing a listof planned activities or milestones of which Partner would like EPA to be aware. For example,
activities may include: (1) increasing the availability of ENERGY STAR qualified products by
converting the entire product line within two years to meet ENERGY STAR guidelines; (2)demonstrating the economic and environmental benefits of energy efficiency through special in-store
displays twice a year; (3) providing information to users (via the website and user’s manual) about
energy-saving features and operating characteristics of ENERGY STAR qualified products; and (4)building awareness of the ENERGY STAR Partnership and brand identity by collaborating with EPA
on one print advertorial and one live press event.

Join EPA's SmartWay Transport Partnership to improve the environmental performance of thecompany's shipping operations. The SmartWay Transport Partnership works with freight carriers,
shippers, and other stakeholders in the goods movement industry to reduce fuel consumption,
greenhouse gases, and air pollution. For more information on SmartWay, visit
www.epa.gov/smartway.

Join EPA’s Green Power Partnership. EPA's Green Power Partnership encourages organizations to
buy green power as a way to reduce the environmental impacts associated with traditional fossil fuelbased electricity use. The partnership includes a diverse set of organizations including Fortune 500
companies, small and medium businesses, government institutions as well as a growing number ofcolleges and universities. For more information on Green Power, visit www.epa.gov/greenpower.

7 CONSIDERATIONS FOR FUTURE REVISIONS
7.1

Displays Larger Than 61” in Diagonal Screen Size

7.1.1

EPA understands that interactive displays greater than 60" in diagonal screen size are currently
available in the market and are namely used for commercial and educational purposes. EPA isinterested in better understanding the power consumption associated with these products whentested according to the Displays Test Method and will work with stakeholders prior to, and during,
the next specification revision development process to access the information. DOE may also
explore testing of these products. EPA is interested in exploring expanding the scope of products
to those greater than 61" in diagonal screen size in the next specification revision.

7.2

Touch Screen Functionality

7.2.1

EPA is committed to continuing to develop performance levels for displays that account for new
features and functionality, and anticipates that displays with touch screen functionality, which areincluded in the scope of this specification, will become more prevalent in the market, especiallyamong signage displays. Going forward, EPA and DOE will explore with stakeholders whether
touch screen functionality impacts On Mode power consumption to determine to what extent thenext specification development process should address touch screen functionality.
