Practice what you preach. That's what Cook & Fox did when they renovated their offices in Chelsea. They went for LEED Platinum in their conversion of what once was a department store dining room. According to the New York Times:
"One of the first things visitors notice when they walk into Cook & Fox is how bright and spacious they feel. Both offices were designed with open architecture and low partitions, so almost all of the desks have window views.
These spaces do not have a new-office odor. Cook & Fox filters out 85 percent of the particulate matter, so the air is much healthier than what the employees would breathe walking down Broadway. The paint, carpet and office furniture are all made from materials that do not emit strong chemical odors." More in the ::New York Times
