What is the Greenest Building?

摘要

The concept of the "greenest building" conjures up thoughts of new, sustain-ably designed buildings with huge alternative energy installations, cutting-edge mechanical and lighting systems, and expansive on-site recycling programs. But as a new report by the Preservation Green Lab (part of the National Trust for Historic Preservation) posits, the greenest building may not be a brand-new, eco-friendly structure. In fact, it's more likely to be an existing building that's been repaired, brought up to code, and retrofitted with energy-efficient systems.
