Baltimore Not Just for Orioles and Ravens -- Hilton Hotel to Bring as Many Birds as Conventioneers

BALTIMORE, MD, Dec 11 (MARKET WIRE) --
The Hilton Baltimore Convention Center Hotel is still about 8 months away from
opening, but the hotel has already set several records for Baltimore's
building industry -- largest number of rooms offered by any hotel in the
city, the largest grand ballroom in Baltimore. Now the Hilton Baltimore
Convention Center Hotel will also boast the city's largest living green roof of
32,000 sq. ft. (slightly larger than the Baltimore Raven's football field)
spanning atop the hotel's East and West buildings.

Construction of the green roofs began in early November and the green roof
on
the East building is now complete, including 60,000 one-inch plugs of six
different species of plants.

Green roof systems are known for benefits such as reducing storm water
runoff,
reducing the amount of blacktop roofs in the city thus reducing the heat
island effect, and reducing HVAC cooling loads thus lowering utility bills.
Green
roofs can also extend those roofs' waterproofing membrane life, help to improve
air & water quality of the surrounding area, and create natural habitats for
birds and other wildlife. Extensive living roofs, such as those on the Baltimore
Hilton Hotel, are 6 inches in depth or less, non-irrigated, designed to be
light-weight and resilient, as well as meet the specific engineering and
performance goals previously mentioned.

As the contractor, Hensel Phelps will ensure that the process for installing
the green roofs on each building is executed properly and keeps within the
designated schedule for the development of the new hotel.

"It's no secret that Hensel Phelps embraces the concepts of sustainable
andgreen building. We are working with an array of expert companies to build the
largest green roof in Baltimore as part of the construction of the Baltimore
Hilton Hotel project," said Stan Carlat, Operations Manager with Hensel
Phelps' Mid-Atlantic District Office.

Several other firms are playing key roles in the construction of the hotel's
green roof. Roofers Ralph J. Meyer Co. of Pittsburgh, PA and local firm Ridge
Roofing of Baltimore, MD will ensure that the hotel maintains a water-tight
roofing system. Furbish Company of Baltimore, MD, which specializes in
sustainable building systems such as green roofs (or living roofs), will handle
the installation of the green roof system. The leading supplier of plants and
plant expertise for extensive green roof systems, Emory Knoll Farms of Street,
MD,
is providing the six different species of plants for the green roofs on the
Baltimore Hilton Hotel.

The installation of the green roof on the West building of the Hilton
Baltimore
Convention Center Hotel is expected to begin after the first of the year.

Previously, the largest green roof in Baltimore City was the living roof
of30,000 sq. ft. planted with atop the Montgomery Park office building in
theneighborhood of Carroll Park.
