Midway Celebration for Clayton GPC

The brand new Clayton offices of Armstrong Teasdale, on the top floor of the soon- to-be-LEED-
certified Centene Plaza, was the setting for the Clayton EPA Green Power Community (GPC) Challenge Midway
Celebration held this past Friday, October 29th, from 4-6:00 pm.

Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building
certification system, providing third-party verification that a building or community was designed and built using
strategies aimed at improving performance across a range of environmental metrics.

GPCs are towns, villages, cities, counties, or Native American tribes in which the local government,
businesses, and residents collectively buy green power in amounts that meet or exceed the U.S. Environmental
Protection Agency’s Green Power Community purchase requirements.

Ameren Chairman, President and CEO, Thomas R. Voss and Clayton Mayor, Linda Goldstein recognized
the 29 Clayton businesses that have already committed to increasing their support of green power to help the city
achieve this prestigious and first- in -Missouri distinction. These businesses are supporting new green power in
Missouri by either purchasing Missouri-originated wind energy credits via the Pure Power program or committing
to installing on-site solar power at their place of business.

The Clayton businesses recognized included: The City of Clayton, The Clayton Chamber of
Commerce, The Clayton School District, Armstrong Teasdale, Araka, Bethesda Health Group, BARcelona Tapas,
Bruce Development, Centene, The Clayton United Methodist Church, Companion Bakery, Concordia Seminary,
De Mun Professional Cleaners, The DESCO Group, Forester Properties, Gladys Manion Realtors, Kaldi’s Coffee,
McAlister’s Deli, Microgrid Energy, Miso, Moneta Group, Portabella, Remy’s Kitchen and Wine Bar, The Sansone
Group, The Seven Gables Inn, The Sheraton Clayton, Straub’s, The Wine Merchant and Westrich Photography.

Since initiating the Challenge via the unanimous vote of the Clayton Board of Alderman, the city, in a
partnership with Ameren Missouri Pure Power and Microgrid Energy has launched a city-wide effort to increase
support of green power in Clayton by Earth Day, April 22, 2011. To date, these 29 businesses have increased the
demand for green power in Clayton by more than 350 Megawatt hours – a full 52% of the EPA required goal for
GPC status and the environmental equivalent of taking 48 gasoline powered cars off the road for a year.
