You know how so many great ideas are ahead of their time? That's kind of how Manhattan condos are. We've always known they're great investments and great places to live. But we didn't really know what we had until we started thinking Green. When some genius designed the first condo (bear with me!), he or she used smart economic principles to create homes that could share resources. Walls, heat, water. Security. Even luxury amenities. You name it. Lo and behold, we've found that the condominium's design is the perfect Green square one. Let's look at how the average condo is great for the environment... then, we'll see how modern developers are taking it a step Greener.
