Connecticut Green Building Runs on Giant Fuel Cell

Big and green don't usually work together when building an eco-friendly apartment building. That's why 360 State Street in New Haven, Conn., is grabbing some headlines.

When done right, high-density urban development is actually greener than suburban sprawl. Indeed, the multi-use property at 360 is something of a pioneer in being big while also raising the bar for green construction to the state of Connecticut.

With a platinum LEED rating -- the highest green grade given to a structure -- the development, which is scheduled to open next week, plans to prove just how energy-efficient high-density structures can be.
