Full Details on the Greening of the Sears Tower
While just about every Chicago news organization carried the news yesterday of the plan to make the Sears Tower more environmentally responsible, most of the coverage consisted of painfully short blurbs with few real details.
So here’s the complete press release, unfiltered, for you to digest on your own:
Sears Tower Unveils Sustainable Plan to Transform Tallest Building in Western Hemisphere
Project will significantly reduce energy use and CO2 emissions, spur economic development
CHICAGO, June 24 /PRNewswire/ — Sears Tower today announced plans for the most significant sustainable modernization projects of an existing building ever undertaken. The project will result in unparalleled energy savings and reduced CO2 emissions to the tallest building in the Western Hemisphere, reducing the base building electricity use by up to 80 percent, which includes a combination of energy savings and co-generation. The energy savings equal 68 million kilowatt hours annually or 150,000 barrels of oil every year. The sustainability plans also drive economic development in the West Loop, creating more than 3,600 jobs, and are part of a broader initiative to transform the global icon.
“Sears Tower, an iconic structure that defines the city’s skyline, will undergo a groundbreaking transformation that creates economic growth with positive impact on our environment, leaving a lasting legacy for future generations,” said John Huston of American Landmark Properties, representing the partnership that owns Sears Tower. “As the stewards of this icon, we take seriously our responsibility to make it relevant and successful, and the changes made and benefits realized through the bold sustainable initiatives at the tower serve as an example that a sustainable future is more than a concept, it is within our reach.”
The building, which already meets Leadership in Energy and Environmental Design (LEED) criteria, will undertake sustainability initiatives above and beyond those used by the United Stated Green Building Council to rate a green building. Modernization strategies, designed by Chicago-based Adrian Smith + Gordon Gill Architecture (AS+GG), include:
-- Efficiency improvements to the building's exterior envelope and
windows. The tower has 16,000 single-pane windows. Sustainability
plans for the building call for a window replacement and glazing
program. Strategies to achieve a thermal break of the curtain wall are
also being investigated. These upgrades would achieve savings of up to
50 percent of heating energy.
-- Mechanical systems upgrades in the form of new gas boilers that
utilize fuel cell technologies, which generate electricity, heating
and cooling at as much as 90 percent efficiency. Mechanical upgrades
also will include new high-efficiency chillers and upgrades to the
-- The tower's 104 high speed elevators and 15 escalators that will be
modernized with the latest technology to achieve 40 percent reduction
in their energy consumption.
-- Water savings that will be realized with conservation initiatives
through upgrades to restroom fixtures, condensation recovery systems
and water efficient landscaping, which will reduce water usage by 40
percent and save 24 million gallons of water each year.
-- Lighting that will be upgraded through advanced lighting control
systems and daylight harvesting, an advanced lighting control system
that automatically dims lights in tenant spaces based on the amount of
sunlight entering through the windows. Combined, these upgrades will
save up to 40 percent of lighting energy consumption.
-- Renewable energy like wind and solar, and technologies like green
roofs that will be tested. Wind turbines will be tested to take
advantage of the tower's height and unique set-back roof areas. Solar
hot-water panels will help heat water for the building. Green roofs
that can sustain high- altitude conditions, and that will be among the
tallest in the world, will be tested to reduce storm water runoff,
improve insulation, help mitigate the urban heat island effect, and
provide pleasant vistas for tenants overlooking the areas.
“Buildings are the world’s largest contributor to carbon emissions, and therefore the biggest opportunity to address climate change is to retrofit existing structures,” said Adrian Smith, partner, AS+GG. “Our goal in the Sears Tower greening project is to create a holistic approach that integrates high-performance building technologies and design strategies for maximum energy efficiency. In the process, we hope to set a benchmark for how high-rise buildings throughout the world can limit their impact on the environment.”
“Sustainable architecture in new buildings is important but not enough to address the climate and energy crises facing our world,” added Gordon Gill, partner, AS+GG. “We have to apply what we’ve learned to our existing stock of commercial buildings–especially iconic structures such as Sears Tower, which we hope will inspire similar initiatives around the globe. These will serve as great examples for building owners and managers and can reposition existing building stock to be as competitive as most new buildings or even better.”
As an important part of the modernization program, Sears Tower’s plazas and retail spaces will also undergo changes. A new park at Wacker Drive and Adams Street will be an inviting public space with landscaping and seating. The Adams Street granite wall will be replaced with an interactive digital display, glass storefronts, and trees, which will be planted to form a landscaped terrace that will add a natural filter for carbon dioxide.
In addition to the most significant energy efficiency renovations ever undertaken on an existing building, another aspect of the transformation is a proposed new, privately funded hotel for the site at Jackson Boulevard and Wacker Drive. The hotel will be designed for a LEED Gold rating, and will become one of the most sustainable hotels in Chicago. The hotel will fill a critical need in the West Loop and provide a much welcomed facility for existing building tenants.
The reduction in energy use and CO2 emissions realized through the sustainability and modernization plans for the tower also brings economic opportunities by creating more than 3,600 jobs. Extending its impact beyond the site itself, the project will feature a dynamic Sustainable Technology Learning Center that is designed to help building visitors and Chicago tourists learn about ways to save energy and money, as Sears Tower serves as a laboratory that demonstrates to the office building industry how a sustainability program can be accomplished.
“The plans for the building bring new activity to the West Loop, and make it even more attractive to current and future tenants who are looking for more sustainable office solutions,” said Robert A. Wislow, chairman and CEO of U.S. Equities Asset Management, the management and leasing agent for the tower. “Today, tenants want the buildings they inhabit to be environmentally friendly and more healthy for their employees. They demand sustainable workplaces. They are doing this because it is the right thing to do, has a positive effect on the environment, helps make their employees more productive and is becoming more and more important to their employees.”
The cost of construction for the Sears Tower project is estimated at $350 million. A number of private and public financing and funding options are being explored. The majority of the energy savings will be realized in approximately five years and work will start immediately.
“The Illinois Environmental Council supports private and public investments in projects that spur job creation and economic development here in Illinois, while helping to meet the challenge of global climate change,” said Charles Jackson, IEC executive director. “The Sears Tower energy sustainability and environmental education project presents a tremendous opportunity for inspiring building owners and the public to aspire to the highest standards of energy-efficiency.”
Sears Tower’s commitment to energy efficiency is well established. Since 1989, the building has reduced its annual electricity consumption by 34 percent. Since 1984, its energy efficiency improvements have resulted in a reduction of 51 million pounds of carbon emissions annually, or the equivalent of removing more than 4,400 cars from the road each year.
