Greenwire's Nathanial Gronewold has a post today on the New York Times Green Inc. blog (http://nyti.ms/9Q4xu2) that gets to one of the thorniest problems facing America's cities: How to deep-retrofit older buildings for improved energy efficiency.
This is hard, messy work that's going require hundreds of billions of dollars and decades.
But here's what he writes about existing structures:
"Having successfully moved new construction projects to the eco-friendly side of the equation with relative ease, officials are now grappling with a far more difficult challenge -- upgrading thousands of existing buildings to stop wasting electricity and curb greenhouse gas emissions."
If you're in construction in New York City, deep-retrofits are the proverbial gold mine.
