Our sun is an amazing star. Not only does it provide energy for plants to grow and life on Earth to survive, but it's also our planet's light bulb! Studies show that whenever buildings let the natural light of the sun in, people feel better and are happier in that building. As a matter of fact, when classrooms get a lot of natural light from the sun, students find it easier to study and learn more!
Green buildings incorporate or use different ways to bring in natural light. This includes adding lots of windows and putting in skylights that are like windows in the ceiling. Some buildings even put in light shelves that help bring light in by bouncing it up to the ceiling and deeper into a room. This diffuses or softens the bright glare that can come from direct sunlight.
