The notion of campuses that are energy-efficient and ecologically friendly, and that provide a healthy, productive, comfortable environment for students and staff has been around for some time. But for many educators, green schools have remained more good intention than proven approach, a huge risk that few school leaders could--or would--take. According to Kristen Heinen, assistant director of the Collaborative for High Performance Schools (CHPS), the idea of green building was unknown to most educators. However, public awareness and interest have grown significantly due to education campaigns on specific environmental problems such as climate change, children's health, water quality, and electronic waste. These issues hit home for parents, students, teachers, and administrators who spend a significant amount of time in school buildings that contribute to these problems. Over the past year, CHPS has seen a steady increase in school districts that incorporate green building practices due to a greater awareness of buildings' impact on children's health and the environment, and also because green schools have proven to be financially beneficial to districts. This article discusses the benefits of green schools and their impact on students' health and the environment.
