Use Natural Light whenever possible. A system of mirrors, lenses and/or lightpipes could provide indoor lighting without using energy gobbling lightbulbs—the only thing is this would only work on sunny days—and hospitals need light 24/7 to provide proper medical care—-so this type of application would work much better in buildings where people are only inside during the daylight hours (SCHOOLS, OFFICE BUILDINGS, and ADMINISTRATIVE BUILDINGS). Also, we could use less energy by installing energy efficient lightbulbs in hospitals (they probably have certain lights that are on 24/7/365 —- so these should definitely be low-wattage)…. It’s like this— if you only have x amount of energy efficient lightbulbs — and a ton of different light fixtures, you decide which ones are turned on the most, and you replace those first! In the afternoons, when I taught science and math at BCS, we sometimes turned the lights off completely, and we could still see fine to learn and study! Think about it! How did humans operate for the 200,000 to 50,000 years before we developed the lightbulb! — WE DID MORE STUFF DURING THE DAY, and RESTED THROUGH THE NIGHT! (we party too much… but also, we have much fun! —IT’s ALL ABOUT BALANCE — always ask (at what cost? — to ourselves, to others, and to the environment — which is the union of self and other — where we live)
While all those suggestions are good, another useful tool is lighting controlled by light and motion sensors. Even though certain areas of hospital need light all the time (and it should be as efficient and as safe as possible) others don’t. By using sensors to help reduce the use of lighting when its not needed, hospitals could save energy.
