4.30.12: Seven World Trade Center, the Empire State Building, and 41 Cooper Square are all LEED certified. LEED, Leadership in Energy and Environmental Design, is a point-based rating system established by the U.S. Green Building Council to drive energy and resource efficiency innovation in the  construction and building industry. LEED certification has become a proxy mission statement for energy efficient buildings made with sustainable materials, nontoxic components, and airy, daylit working environments. But LEED is often criticized for encouraging “point chasing.”

NNR producer Sarah Bacon spoke with four LEED industry experts to understand the differences between certification levels; why developers would seek LEED certification and why some choose not to, and the importance of a post-occupancy performance. She met Jody Grapes, Director of Facilities Management at The Cooper Union’s LEED Platinum 41 Cooper Square; Chris Garvin, Partner at planning and design firm, Terrapin Bright Green; Brooks Perlin, CFO of ECO Supply, a green building materials vendor, and green developer Seth Brown, CEO of Aspen Equities.

2.10.12: In the latest installment of Ask The Expert, producer Ben Pomeroy visited with Emily Landsburg, CEO of Black Gold Biofuels to learn about the infrastructure scourge and energy potential of used cooking oil’s less glamorous cousin, restaurant grease trap waste. Unlike yellow grease from cooking oil, grease trap waste had no practical applications until Landsburg and her company created one that’s now adding value for towns and cities.

10.28.11: Last year the Gowanus Canal was designated a Super Fund site by the Environmental Protection Agency in order to remove the chemicals, heavy metals and volatile organics from what that agency called, “one of the most extensively contaminated waterways in the nation”.

Producer Ben Pomeroy visited the Gowanus and the surrounding neighborhood to learn some of it’s history and the people who live and work around it’s banks.

He discovered that behind it’s somewhat mistaken reputation as a fetid body dump- is a Revolutionary War battle site, a tree from China, a third generation family company and a foster home for the set pieces of the next blockbuster movie.
