If Betty White Were a Green Building...

Perhaps you've heard the idea that "the greenest building is the one already built." Our friends in the historic preservation movement use this phrase to argue that tearing down an existing building and starting from scratch wastes a lot of materials and energy. And they have a point: A recent report from the National Trust for Historic Preservation concludes that it can take up to 80 years to make up for the environmental impacts of demolishing the old building and constructing the new one, even if the new one is super energy efficient.

Could this be the next star
of the green building movement?

So, granted, in most cases it's better to keep a building than to build a new one, but let's think about that creed again: The greenest building is the one already built. What if you’re not planning a new building? Does that mean your existing building is already green? Does the mere fact that something already exists mean that it exhibits certain qualities? Does the fact that you were born mean that you live a healthy, prosperous and generous life? One can argue that our experiences and aspirations say substantially more about who we are than our DNA ever will. The same holds true for buildings.

Let's face it; LEED was conceived because there are a bunch of really bad buildings out there. They use too much energy and water, and make people sick. But the solution isn't to just tear them down and start over. Existing buildings, and in particular historic buildings, tell valuable stories. They've been worked in, lived in, and loved in. They teach us about our past and form the bedrock of our communities. But just like your wise but slightly behind-the-times grandfather who doesn’t quite get what those new-fangled CFLs and LEDs are all about, sometimes we need to drag those old buildings, kicking and screaming, into the 21st century.
