LEED Certified Caterpillar Financial Center Conserves Water with Environmentally Friendly Ozone Water Treatment

Caterpillar Financial Center in Nashville, Tennessee pursues water conservation with environmentally friendly ozone water treatment.

It was awarded Gold Certification for an existing building under the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program in April of 2009. The certification makes the center the first building in the Caterpillar family and the first privately owned, existing commercial building in Tennessee to become LEED certified. The Gold Certification is the second highest rating in the LEED system.

Flozone Services, Inc. contributed toward the reduction in energy and water usage on the HVAC system by installing an Integrated Management System (IMS). Since installing the IMS on the condenser water system, the Caterpillar Financial Center reduced water usage by 30% and energy usage by at least 5.5% annually. The IMS also eliminated the 14+ barrels of cooling tower chemicals annually and reduced the sewer load to help preserve the environment. In addition to these savings, Flozone continues to protect the HVAC equipment and extend the life cycle many years.
