PLU is currently in the process of remodeling and reconstructing multiple buildings throughout campus. The goal is for each building to obtain a Leadership in Energy and Environmental Design (LEED) rating of Gold. Currently two buildings have been awarded a Gold rating by LEED. In 2006 the Morken Center for Learning and Technology became the first building to earn the award. The Morken Building is home to the School of Business and the Computer Science department. This 55,000 square foot (5,100 m²), $21 million building requires no fossil fuel to operate and is heated and cooled by using a geothermal heat-pump system that regulates its temperature with water stored in 85 wells located 300 feet (100 m) underground. In 2009 a second building would earn the LEED Gold rating when the Martin J. Neeb Center was completed. This building was home to the radio station 88.5 KPLU and at the time of the award being presented it was the only radio facility in the nation with a LEED Gold ranking. The University Center was the third building to receive a LEED rating. Following the completion of the 2006–2007 academic year, the University Center underwent $14 million in construction renovations and as a result earned a LEED Silver rating.
