Highlights
Resource Stewardship in Use: on-site infiltration best choice for stormwater management
Financial Stewardship: stormwater infrastructure savings
Aesthetics: attractive detail on roadways and clarity for pedestrian areas
George Bialecki Jr. takes green building seriously. As developer of age 55+ communities, environmentally responsible design saves his projects money and sells his energy-saving units more quickly. For example, PICP (permeable interlocking concrete pavers) saved thousands of dollars by eliminating conventional storm-water drainage at Autumn Trails, an independent living community with 32 homes located in Moline, IL, as shown in Fig. 1. The savings was so great that it made PICP cost-competitive with conventional asphalt and concrete pavements.
Highlights
Resource Stewardship in Use: mix and structural design reduced total material use
Resource Stewardship in Supply Chain: reclaimed waste in mix
Financial Stewardship: long service life, more parking on same area due to longer spans
Aesthetics: longer spans allow more open feel and better visibility
The Midfield Terminal at the new Indianapolis International Airport opened in 2008, and includes a massive 7000-car parking garage. Each of the five parking levels is approximately 500,000 ft2 (46,500 m2). The two-way post-tensioned concrete design for the garage maximized the benefit from the chosen HPC mixture.
Highlights
Resource Stewardship in Use: thermal mass and radiant heating
Aesthetics: precast used to repeat brick and block façade style on campus
Awards and certifications
LEED Silver
Highlights
Resource Stewardship in Use: thermal performance, durability

Highlights:
Safety and Stability: pervious paving reduces icy surfaces making safer walking and driving conditions
Financial Stewardship: designed reduced maintenance
Aesthetics: helps retain ecological integrity of nearby creek
Awards and certifications
PCA Sustainable Leadership Award (to the city of Leawood, KS, for the I’Lan Parking Lot)
Structure specifics
Highlights:
Resource Stewardship in Use: extensive stormwater features – green roof and cistern
Resource Stewardship in Supply Chain: slag cement replaced portion of cement, local precast producer, recycled pavers
Aesthetics: green roof embellishes attractive design, reduced sprawl by denser site use
Awards and certifications
LEED Certified
International Parking Institute Award of Excellence
Precast/Prestressed Concrete Institute Best Parking Structure
Highlights:
Resource Stewardship in Supply Chain: extreme recycling tested
Safety and Stability: mass concrete for x-ray testing containment
American Engineering Testing Inc. (St. Paul, MN) used the design and construction of a new X-ray vault to reduce a concrete mixture’s carbon footprint and the potential for a reduction of virgin material. The vault is entirely concrete, with a plan section of 30 x 20 ft (9.1 x 6.1 m), 12 ft high (3.7 m), and 3 ft (1 m) thick walls. The target strength was 4000 psi (27.6 MPa) at 56 days.
Highlights:
Financial Stewardship: concrete solution reduced costs on tight site
Aesthetics: rooftop garden serves the community and residents
This 106,000 ft2 (9900 m2), seven-level parking structure provides 325 parking spaces for the adjacent condominiums. An all-precast solution was used to meet the owner’s needs for a highly sustainable design that would attract attention as a green project while also having tight budget and schedule constraints. The focal point of the parking structure is the 16,000 ft2 (1500 m2) rooftop garden.
Highlights:
Financial Stewardship: urban revitalization, transit oriented development, high energy performance, local content
Resource Stewardship in Use: energy performance, indoor air quality, recycled content, daylighting, green roof
Aesthetics: sound attenuation
Through the use of concrete and other green elements the Bethel Commercial Center, a new, mixed-used transit center in a low income neighborhood on Chicago’s west side, is expected to use 50 percent less energy than conventional construction. The building has been designed to achieve a LEED Gold rating.
Highlights:
Financial Stewardship: low long term maintenance for taxpayer
Resource Stewardship in Use: stormwater management
Safety & Stability: public open space which promotes international understanding
When the City of Leawood, Kansas, implemented new regulations requiring developers to address stormwater runoff for the health of the community, local officials knew that their own construction practices would reflect the expected and required policies in the community.
