History

Originally constructed in 1952, the site and building have been owned by many different companies. In 1995, the Sacramento Crushing Company, a construction and demolition debris recycling company occupied the site. Sacramento Crushing had exceeded the scope of its permit and the Chicago Department of Environment began an investigation. The site was filled more than 600,000 cubic yards of waste that had been illegally dumped over three decades. This debris was piled high and caused compaction on some areas of the site. The Illinois EPA cited the company for illegal dumping and operation of a waste storage and treatment facility.

Renovation

Renovation of the . building cost a total of $5.4 million and lasted from 1999 to 2003, at which point it was opened to the public. Before the formal

began, it was decided that the main goal of the renovation was going to be that the building had to pass the U.S. Green Building Council's LEED Platinum rating, which is the highest LEED rating a building can get. The goal to have the building be LEED Platinum certified was the determining factor in all building decisions, such as mechanical, electrical, and ventilation systems. All aspects of the building were optimized in order to reduce waste during the construction process, and energy waste during the operation of the building once it was completely renovated.

Water is pumped down the wells and then extracted, which helps cool the building in the summer and heat it in the winter.

, which consists of of soil and plant matter. The green roof helps to absorb rainwater and insulate the building. Rainwater is released from downspouts into the soil, as opposed to the public sewer system, in order to reduce the amount of run-off contaminants in the sewers. The landscaping around the building is irrigated with rain water that is stored in cisterns, which helps reduce the amount of treated water from the city.
