Two new buildings since 2000 include the von Liebig Center for Science and the Suzanne von Liebig Theatre. Founders Hall, the first building on campus, has also been renovated recently. Construction was finished in the summer of 2009 and uses underground geothermal energy to heat and cool the building. This building is recognized as a LEED Gold building. A newer building project on campus is Nathan Hall, a dormitory named in honor of longtime Juniata employee, Hilda Nathan. Hilda worked in the treasurer's office from 1946 to 1976. The new residence hall, which opened to students for the fall 2014 semester, offers significant improvements in the areas of accessibility, community and sustainability. Nathan Hall has an elevator and is designed for accessibility throughout the building. The space also is designed to foster community with features such as informal gathering spaces and lounges within the building and outside. The dorm also was constructed using "green" technologies such as geothermal heating, energy-efficient lighting, plantings and green spaces. The building also offers a bike shelter to encourage less driving. The newest building at Juniata College is the Tom and Pat Kepple Integrated Media and Studio Arts Building, or more briefly, Kepple Hall. Opened in 2017, this building includes four separate studio rooms and numerous innovative spaces for students to learn and collaborate in the creation of art. Other off-campus sites include the Baker Peace Chapel (designed by Maya Lin) and the "cliffs," which has views of the Juniata River. The college also owns the Raystown Field Station, a 365-acre (1.48 km2) reserve on Raystown Lake, which includes an LEED Gold building and two lodges for semester-long residential programs, often focused on environmental topics. Carnegie Hall was completed in 1907, paid for in part by a grant from U.S. Steel magnate Andrew Carnegie and served as a library for Juniata until 1963, when the college's current L.A. Beeghly Library was completed. The Museum houses a permanent collection, which includes works from the Hudson River School, American portrait miniatures, as well as Old Master paintings and prints. The Museum hosts regional, national, and international exhibitions. Academics Program of emphasis Juniata College features a "Program
