This is UofL’s sixth building to meet LEED sustainable green building standards.

The $45 million project added more than 20,000 square feet and renovated another 211,000 square feet to the facility, improving its capacity for innovation and new technology.

Among the green changes are more efficient HVAC systems and lighting that turns on only if someone is in a room. Additional improvements will result in a 7 percent increase in energy efficiency and an annual reduction in water usage by 534,455 gallons. The project used more than 30 percent recycled and regional materials.

The U.S. Green Building Council established the LEED rating system in 2000. Businesses, schools, government agencies, stores and homes can apply for certification through the program, but must meet strict criteria before they can qualify for a certified, silver, gold or platinum rating.
