SECOND QUARTER 2006
18 From Waste to Success: Saving district energy in Nashville
Harvey W. Gershman, President, Gershman, Brickner & Bratton Inc.
After nearly 30 years of service, downtown Nashville’s once-innovative waste-to-energy steam
and chilled-water plant was increasingly unreliable and costly to operate. In 2000, Mayor Bill
Purcell ordered a study of alternatives for the facility. It ultimately led to a unique public-private
partnership and creation of a self-sufficient new district energy system. A tour of the system will
be available to 2006 annual conference attendees.
5 Where the Rubber Meets the Road: Scrap tires viable fuel
Kelly M. Dodson, Marketing Manager, Akron Thermal
To cut its natural gas use, Akron Thermal’s district energy plant introduced recycled waste wood as
a fuel. But maintaining a consistent waste wood supply was a challenge. Scrap tires proved to be
the ideal fuel supplement. Now in its second heating season burning ‘tire-derived fuel,’ the system
has achieved dramatic fuel savings.

9 District Energy in Southampton: U.K. best practice in
Simon M. Woodward, Chief Executive, Utilicom Ltd.
Southampton, United Kingdom, may be an unlikely place for a district energy system. But after
a government research program drilled a geothermal well there, then abandoned it, city officials
sought private-sector help to develop the resource into what is now the largest commercially
developed district energy system in the country.
14 WebLink – Designing for the Future: UNC’s new infrastructure
Thomas Parker, PE, Carter & Burgess; Ray DuBose, PE, University of North Carolina at Chapel Hill
The University of North Carolina (UNC) at Chapel Hill will add 6 million sq ft of building space over
the next decade. When state higher education funding became available, UNC responded by
developing an infrastructure master plan to support campus growth. Plans include a new central
steam plant. Full article online at www.districtenergy.org/weblink.htm.

Energy System’s new plant, this is a view of
downtown Nashville, the system’s service
area. As evidenced by the cranes, the downtown area is healthy and growing. According

five years, Nashville is going to be a place
which is hard to envision today.” Copyright
