The recently completed KONE Centre – featuring 125,000 square feet of
office, restaurant and retail space – is a showcase for sustainability
along the Mississippi River in Moline, Ill. The eight-story structure’s
sustainable design includes 1,365 solar panels, light-harvesting
technology, locally sourced recycled and renewable construction
materials, and a host of energy-efficient building components. In
addition, the shape of the building follows the solar axis and takes
advantage of natural daylight.
A spectacular addition to the city’s riverfront when it officially
opened in August, the multi-use facility was constructed with
high-performance concrete containing Lafarge North America products:
True Lite Lightweight Aggregate and a blended cement that included
Class C fly ash and NewCem slag cement. These products,
which are considered post-industrial recycled materials, made essential
contributions to meeting the sustainable construction goals of the KONE
Centre, which is expected to earn a LEED Gold rating from the U.S. Green Building Council.
The use of supplementary cementitious materials, such as fly ash and
slag cement, as a partial replacement for portland cement can help
designers and builders recycle industrial by-products, achieve higher
performance from concrete mixtures, and earn points toward LEED
certification of their projects. These blended cements have many
properties that contribute to sustainable design - they produce stronger,
longer-lasting concrete, reduce the consumption of nonrenewable raw
materials, consume less energy, and turn by-products from other
industries into resources that would otherwise be disposed of in
landfills. Fly ash is derived from burning coal in electric utility
plants, and slag cement is produced from granulated blast furnace slag, a
by-product of the iron-making process.
Lafarge True Lite Lightweight Aggregate is also a recycled by-product
of the iron production process. About 35 percent lighter than
most natural aggregates, this expanded slag product conforms to the U.S.
and Canadian governments’ environmentally preferable purchasing
programs and qualifies for points under many LEED credit categories. It
offers excellent fire resistance, thermal insulating, and sound
absorption capabilities and can help reduce heating and air-conditioning
costs due to the capillary nature of the aggregate.

South Carolina School Uses Sustainable Design
Hanson Brick is working with Jumper Carter Sease Architects, P.A., CJMW Architecture and Lexington County School District One to create the new River Bluff High School. The school will be located near the intersection of highway 378 and I-20 on Corley Mill Road in Lexington, S.C., and is housed on a site previously owned by Guignard Brick Works. The project’s use of recycled job site materials, conceptualized by CJMW Architecture and JCS Architects, supports Lexington County School District One’s vision of a sustainable 21st Century school and provides a place for students to learn and grow.
“This project helps us build a school, while focusing on our community and keeping the environment in mind,” says Mary Beth Hill, chief communications officer for Lexington County School District One. “The use of recycled materials is cost efficient and allows us to be good stewards of our taxpayers’ dollars.”
The jobsite existed previously as an old shale pit, occupied by Guignard Brick Works. When in operation, Guignard Brick Works was the oldest continuously operating brick company in the United States. Hanson Brick was selected to provide the brick needed to complete the project, due to their ability to manufacture new bricks from existing jobsite materials at a low cost, as well as for their expertise within the industry and the overall economic benefits. Additionally, Hanson’s Columbia Brick facility is located about 12 miles from the jobsite, which also minimized transportation costs.
“Perhaps the most exciting aspect of my initial idea for using the site’s own earth to create bricks for the facility is that Hanson’s enthusiasm for the concept spawned other resource-conserving measures such as ice storage for the cooling system and the use of natural light in lieu of reliance on electrical lighting,” says Michael Kohn, principal at CJMW Architecture.
To date, Hanson has manufactured about 600,000 utility-sized “River Bluff Blend” bricks, a product design used exclusively for this project. While the majority of materials used consisted of shale from the project site, kaolin from nearby areas was required in regional manufacturing as well in order to meet the standards of the American Society for Testing and Materials.
“This project is part of our ongoing commitment to make the best use of our resources,” says Charlie Ward, senior VP and general manager of Hanson Brick. “Our ability to reuse existing site materials is not only a benefit for our customers, but for our community as well. This was truly a team effort, and credit should be shared with JCS Architects; CJMW Architecture; Southern Management Group; The Exum Co.; Mid State Masonry Contractors; and China Construction.”
River Bluff High School is currently on schedule to open during the summer of 2013.
