Green Term Defined: Conservation

Conservation, to me, is the key to a more energy-efficient future for our built environment. It is the act of preserving, guarding, or protecting the resources we have available on this planet.

With stats like these you can see how cutting energy use in existing buildings is a key to our efficiency future. We can do a lot with new buildings, but we have an aging building stock that needs lots of attention. 72% of buildings in the U.S. is over 20 years old. Conservation is the key to improving our building stock and cutting our annual energy use.
