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 informed

on the progress of these efforts:

¦	Provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
availability 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 ENERGY
STAR website), EPA may provide links where appropriate to the Partner website.

¦	Ensure the power management feature is enabled on all ENERGY STAR qualified displays and
computers 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 the
program requirements listed above. By doing so, EPA may be able to coordinate, communicate,
and/or promote Partner's activities, provide an EPA representative, or include news about the event in
the ENERGY STAR newsletter, on the ENERGY STAR website, etc. The plan may be as simple as
providing a list of 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 the
company's shipping operations. The SmartWay Transport Partnership works with freight carriers,
shippers, and other stakeholders in the goods movement industry to reduce fuel consumption,
