Striving to provide the nation’s children with a healthy place to learn is not a new concept. As long as there have been school buildings, there have been advocates for architectural improvements to ensure that students had proper lighting, heating, and fresh air. But with the real problems of overcrowding, age, and budget crises, many green visions have fallen short. With that being said, the Green Schools exhibition at the National Building Museum, which began this month and will run until January 4, 2014, will look at several examples of what is possible—at the future that, in some places, is already here—and provide resources for all of us to consider as we look toward constructing the next generation of school buildings.
