Knox County Ceremony to Launch $16.2 Million in Infrastructure Improvements

-- High Performance Upgrades Will Reduce Energy Costs by 36 Percent --

Knoxville, Tenn., Aug. 18, 2009 — Even with autumn just around the corner, it seems that
nearly everything in Knox County is going green. Knox County administrators are undertaking
$16.2 million in improvements to address aging infrastructure and high energy and operating
costs. The county will combine anticipated energy and operational savings with $2.1 million in
U.S. Dept. of Energy Tennessee Block Grant Funds to fund the improvements.

When completed, the improvements will reduce the county’s energy costs an estimated
36 percent by upgrading and enhancing infrastructure in 40 facilities, 24 parks and 37 traffic
intersections. The improvements are also expected to add county jobs, create one of the
nation’s largest solar farms and significantly reduce the county’s environmental impact while
providing a more productive and comfortable environment for county employees and residents
who use county services.

Over the 15-year life of the program as it was approved by the Knox County commission, the
county will save an estimated $29 million, more than covering the program’s $27 million cost.
This total cost includes: $16.2 million in infrastructure upgrades, $7.5 million in maintenance and
repair services and allotments for debt service and measurement and verification services. The
resulting project requires no new tax dollars.

Ceremony and Reception Will Launch Improvements
A ceremony and reception will be held to formally launch the infrastructure improvements on
Monday, Aug. 24, at 11 a.m. at Lawson McGhee Library, 500 West Church Ave., Knoxville,
Tenn.

“These improvements will generate benefits throughout the county for taxpayers, county
employees, jobs seekers, the environment and the economy,” said Mayor Mike Ragsdale. “Knox
County’s reputation as an environmental steward will be stronger than ever.”
By implementing this project, Knox County government leaders also anticipate that they will
maintain and/or create 176 sustainable county jobs based on the latest United States
Department of Energy job creation calculations.

The improvements will have a significant positive environmental impact, equivalent to removing
2,329 passenger vehicles from Knox County roads, according to the Environmental Protection
Agency (EPA) greenhouse gas equivalence calculator.

Improvements Address County Goals
Before selecting energy conservation measures, Knox County government leaders conducted a
comprehensive energy and utility analysis of county facilities. Using these detailed results of
energy and utility consumption, they modeled various energy conservation measures to
calculate the best potential solutions.

The selected improvements address the business objectives identified at the outset by Knox
County administrators:

• Eliminate up-front capital costs
• Update aging infrastructure
• Reduce operating costs
• Reduce the county’s environmental impact
• Incorporate alternative energy solutions
• Create local jobs
• Protect the county’s investment

The project is anticipated to be funded by a block grant and by a performance contract, which is
a package of products and services customized to building requirements to deliver significant
energy and operating cost reductions.

One of the most significant planned improvements is a solar farm which will be completed later
this year. As one of the nation’s largest solar thermal hot water installations, the solar farm will
feature 300 solar collectors with 13,978 gallons of hot water produced and stored each day.
The improvements also incorporate agreements for maintenance and repair services for many
of the county’s facilities, turning them into long-term fixed costs. The maintenance and repair
services will protect the county’s assets and assist the county with efficient long-term operation
and with EPA regulatory compliance for refrigerant management and disposal.

Customized Solutions Incorporated Throughout County
A variety of customized solutions were selected to address the county’s needs. Improvements
to county facilities will include upgrading lighting systems in nearly all buildings for greater
efficiency. Water conserving system upgrades are also planned for more than a quarter of the
county’s buildings. Nearly all of the buildings will receive upgraded controls or building
automation systems for greater efficiency, centralized control and remote access.

High efficiency heating, ventilation and air conditioning systems will also be installed to replace
aging and/or outdated systems in approximately a quarter of the buildings. Administrators have
also selected low maintenance, highly efficient LED (light emitting diode) traffic signals for 37
county intersections.
