The Environmental Interest House—known colloquially as The Outhouse—was established in 1981 as a part of the Interest House Community. It provides housing for several environmentally minded students every year. It is situated on Boyer Ave in the IHC, right next to La Madison Francais. The students involve themselves in addressing environmental issues on campus, and act as leaders toward a more sustainable Whitman campus. It is a very active group of students. One of their biggest activities is spearheading the campus recycling program. The Recycling Center is located behind the outhouse, and the residents of the Outhouse are key to its operation. The Outhouse also puts on events each year such as the well-known “Outhouse Unplugged” where students can perform live, acoustic music or read poetry by candlelight. The building itself has a number of environmentally friendly measures taken to make it more sustainable, such as a small solar array on the roof and a passive solar water heating system.
