We need to slash our footprints, not by 20% but by 80%, and not in 50 years but in 10. And while in the U.S. buildings are under 50% of our energy consumption, in New York City, 80% of our carbon footprint is buildings-related; and of the buildings that will define our streetscape in 2030, 85% are here now. Most of that footprint is electricity, and most of that electricity is made with coal. So...renovating green is critical.
But a green renovation in an older, multifamily building has challenges of its own: One shares services and walls and has to play nicely with others. One has to be respectful of the existing building fabric. Doing a green urban retrofit is still new ground.
