[ Updated 02.08.2011: Added the interview video, a gallery of Scarpa's 502 Colorado project, and more. ] You know you've hit the big time when you're not only invited to appear on Oprah, but you're interviewed by Leonard DiCaprio on Oprah. Such is the case with Larry Scarpa, of Santa Monica firm Brooks + Scarpa, who talked to Leo about his former firm Pugh + Scarpa's 502 Colorado in Santa Monica, which DiCaprio calls the “first green affordable housing project in the country.” Whether or not that’s true, the building does include 200 solar panels on its rooftop, providing much of the building’s energy. DiCaprio doesn’t ask Scarpa about any of the 44-unit building’s other green elements (including strategic orientation, natural ventilation, co-generation, and recycled materials), but that’s okay, he'll dream about it later. At least Scarpa gets to remind stubborn developers that building green can be cheaper than conventional building. By the way, we think Scarpa, who’s already a dead ringer for Top Chef’s Tom Colicchio, has earned himself a spot on DiCaprio’s next film, Devil in the White City, about the architects of the World’s Columbian Exposition in Chicago. Wake up and get that architect an agent NOW.
