Clemson University’s Lee Hall III academic building has been awarded LEED Gold certification by the U-S Green Building Council. Lee III is a 56,000-square-foot expansion of the original Lee Hall, the home of the School of Design and Building and the department of art. It is zero-energy-ready, designed to offset its energy expenditure by producing as much energy as it consumes. Monitors in the building indicate when outside conditions are favorable to natural ventilation provided through windows. Mechanical windows open and shut automatically when temperature and humidity reach threshold levels. Skylight and window walls provide natural light during daytime hours, limiting the need for artificial lighting.
