Chicago-based
Exelon Corp. recently announced that the U.S. Green Building Council
has awarded Exelon’s headquarters with the Leadership in Energy
and Environmental Design (LEED®) Platinum Commercial Interiors (CI)
certification.Exelon’s new green headquarters is the largest office
space in the U.S. to be LEED-CI certified at the platinum level.
“We
are very proud of this accomplishment," said John W. Rowe, Exelon’s
chairman, president and CEO.“This is the largest office space
in the US to be certified under the LEED process at platinum status
– the highest environmental rating awarded by the U.S. Green Building
Council.We are also pleased to help Mayor Daley, Commissioner Johnston,
and the City of Chicago meet their environmental goals through our compliance
with The Chicago Standard for sustainable buildings.”
Exelon is
addressing climate change by improving its own operations.In 2005, Exelon
established a voluntary goal to reduce greenhouse gas emissions by 8
percent from 2001 levels by the end of 2008, and this goal will be partially
realized through the redesign of its company headquarters.
“I
applaud Exelon on the platinum LEED certification for their headquarters,
and we hope that others in the private sector will follow their lead
in sustainable building practices,” said Sadhu Johnston, Commissioner
of Chicago’s Department of Environment.“ Chicago is proud
to be home to three platinum LEED certified buildings or office spaces
with the first being the Chicago Center for Green Technology.The City
of Chicago is committed to constructing all new city owned facilities
to LEED standard.”
Exelon consolidated
its downtown Chicago locations and one suburban location to increase
productivity and reduce long-term occupancy costs. To do so, Exelon
chose to renovate existing space to LEED standards rather than building
new. The project involved the design and construction of more than 220,000
square feet of office space on ten floors in an existing landmark building
in downtown Chicago .
In its new
green headquarters, Exelon has reduced electricity consumption by more
than 43 percent and water consumption by 30 percent as compared to its
previous space and has created a healthy and more productive work environment
for its employees.From workstations, offices and conference rooms, all
employees have outside views so they can benefit from natural light.In
addition, air quality was improved through the use of low-emitting materials,
paints, carpeting, furniture and finishes, and the installation of high-density
air filters.
Exelon purchased
more than 60 percent of the project and construction materials from
manufacturers located within 500 miles to reduce emissions associated
with transportation
.Three-quarters
of construction waste was recycled or salvaged, and almost one-third
of furniture and other materials were reused to reduce waste.Exelon
is also buying Renewable Energy Certificates to offset 100 percent of
electricity usage for the office space from regional, Green-e certified
wind power. The office at Chase Tower, 10 S. Dearborn, is near public
transportation, and offers bicycle racks and showers for employees who
want to ride their bikes to work to further reduce emissions.
“Energy
efficiency and sustainability have become two of the most important
factors in building design.I’m optimistic that Exelon’s
leadership in building green will inspire other similar projects,”
said Donna V. Robertson, dean of the Illinois Institute of Technology’s
College of Architecture.
“Exelon
has demonstrated an unwavering commitment to the environment by striving
and obtaining platinum, the highest level of LEED certification,”
said Rick Fedrizzi, president, CEO and founding chair of the US Green
Building Council. “Buildings are responsible for 39 percent of
CO2 emissions in the U.S. , which directly impacts global climate change
– however LEED buildings consume half the energy of conventional
buildings. Companies like Exelon recognize the full environmental impact
of their decisions and will serve as an example for other organizations
to follow.”
The LEED
Green Building Rating System is a voluntary, consensus-based national
standard for developing high-performance, sustainable buildings. The
rating system was designed by leading experts in the construction industry
to promote buildings that are economically profitable, environmentally
friendly, healthy and productive places to work. Platinum-CI certification
of Exelon’s headquarters was based on ratings in six categories:
sustainability of the site; water efficiency; energy and atmosphere;
materials and resources; indoor environmental quality; and innovation
and design process.
“The
complexity and size of this project necessitated a great deal of upfront
planning and a truly integrated approach with all of the team members
participating in the process.Exelon’s vision and environmental
commitment, as well as their ability to assemble a strong project team,
were key to achieving LEED-CI Platinum certification,” said Helen
J. Kessler, FAIA, LEED A.P., of HJKessler Associates, Exelon’s
LEED consultant on the project.
