LEED Renovations: What's Old is New Again


LEED for renovations is not as widespread as LEED for new, but it is gaining in popularity. There are so many things one can do to make an old building healthier and more energy efficient; much of them have to do with taking the building back to its original form. For example in this picture one can see that there are terrazzo floors and no suspended ceilings, eliminating major dust catchers. Older buildings were built with high ceilings and high big windows to maximize natural light; energy was expensive and there was only incandescent light when they were built. Windows were double hung with top and bottom panes moving; Georgian English builders learned that double hung windows create a convection current that brings fresh air further into a building than any other kind. When it comes to healthy, efficient buildings, what's old is new again. Read about a project in Seattle in ::New York Times
