The 22-story apartment tower in Portland, Oregon, has a roof garden that funnels rainwater to its public toilets. Because the water isn’t treated, state law requires “Do Not Drink” warning signs.

Green features, such as reusing rainwater and generating about 1 percent of the tower’s electricity with four rooftop windmills, help the Indigo’s bottom line by saving energy and attracting tenants who pay a premium to live an eco-friendly urban lifestyle, said Mark Edlen, chief executive officer of the closely held company that’s developed $5 billion of residential and commercial real estate since 1996.
