HUNTERSVILLE, N.C. -- May 03, 2012

Lime Energy Co. (NASDAQ: LIME) announced today the completion of their LEED
Gold Design-Build-Exhibit Project at Table Rock Dam and Lake. The $10.4
million, Dewey Short Visitor Center encompasses 15,000 square feet with an
emphasis on energy efficiency, sustainability and educational exhibits. The
exhibits were developed to proactively engage the public in sustainability
experiences that encourage a broader appreciation of the features and
resources of the entire region. The new center is named in honor of
Congressman Dewey Short, who was instrumental in the approval of the Table
Rock Project – a 252 feet high, 6,243 feet long concrete dam which provides
flood control for 4,020 square miles of the White River watershed and a 52,300
surface area lake next to the popular tourist destination of Branson, MO.

Lime Energy was awarded the design-build task order by the US Army Engineering
and Support Center, Huntsville, AL, through their Facility Repair and
Renewable (FRR) Contract in May 2010. Through comprehensive master planning,
multi-disciplinary design and the resulting construction of the visitor
center, Lime Energy provided a whole-site solution that incorporated site
drainage and storm water quality management via bio-swale (rain gardens),
minimal site maintenance and zeriscaping (local natural landscaping).
Internally, the center utilizes ambient daylighting, energy efficient
lighting, recycled, non-toxic materials, water efficient fixtures, closed loop
geothermal (water to water) HVAC and enhanced systems commissioning that
ensures all building systems perform at an optimum level. “Lime Energy was
cognizant from the onset of the Army Corp’s desire to not only construct a
world class facility, but to incorporate truly sustainable, low maintenance
and energy efficient practices into the on-going operation of the center,”
said Deane Leidholt, Director of Operations. “To further contribute to the
LEED Gold Design parameters, the building’s energy efficiency is 35% below
current ASHRAE standards and 83% of our construction waste was recycled.”

In addition to the expected environmental and tourism impact, the two year
project also provided another local benefit to the Branson and Springfield
Communities. “The US Army Corps of Engineersand Lime Energy were determined to
source materials and labor locally,” said Jim Smith, Executive Vice President
of Lime Energy. “Over the course of the two year project, Lime Energy hired 40
local subcontractors whose 100+ workers put in 50,000 man hours of no-accident
work to complete the center. This is further testament to Dewey Short’s
reputation of a world class Visitor Center.”
