Edward B. Bunn, S.J. Intercultural Center, Washington D.C.

The Edward B. Bunn, S.J. Intercultural Center, commonly known as the Intercultural Center or ICC, is named after Edward B. Bunn, S.J. This seven-story building was constructed in 1982 as part of the Photovoltaic Higher Education National Exemplar Facility, thanks to a grant from the U.S. Department of Energy. Its design and construction were pioneering at the time, marking a major advancement in the integration of solar power in educational facilities.

The ICC is home to numerous administrative offices, student facilities, and conference spaces, making it a central hub of activity on campus. Among its prominent occupants are the Edmund A. Walsh School of Foreign Service, the Center for Contemporary Arab Studies, and the Prince Alwaleed Bin Talal Center for Muslim-Christian Understanding. Additionally, it houses several departments of Georgetown College, further underscoring its importance as an academic and administrative center.

Originally, the ICC was planned to be the largest photovoltaic installation in the world. When completed, it was one of the largest photovoltaic systems ever constructed, producing an impressive 360,000 kilowatt-hours of electrical power annually at its peak. Over time, the efficiency of the solar panels has declined, and the current generation stands at approximately 200,000 kilowatt-hours per year, meeting about 6% of the building's energy needs. The solar panels feature a unique rough glass surface, which, while reducing their efficiency, was essential to prevent glare that could affect airplanes flying out of the nearby Reagan National Airport.
