This is a quality video by Wall Street Journal’s Dana Mattioli featuring Andrew Shapiro, founder and CEO of GreenOrder. GreenOrder is a sustainable marketing and strategy firm that’s been called the "Green McKinsey" on occasion. Shapiro takes Mattioli through 7 World Trade Center, explaining the building’s several green aspects, including the rainwater reclamation system, floor-to-ceiling windows, design for natural lighting, and white roof. You’ll notice also the layout of employees, which is a little more collaborative and fluid. Experts laud these open layouts as a way to do more with less space, and thereby, save materials. I’m still unsure as to whether tighter quarters can be more effective, especially with the extra noise and commotion — I definitely think it depends on the job type. It probably reduces internet usage, though.
