The "energy-efficient" sealed commercial buildings constructed after the 1970s energy crisis 75 indoor air quality problems caused by materials such as paint, wall covering and carpet. So far 20 years. we've been focusing on these materials 76 to the molecules, looking for ways to make them 77 for people and the planet.

It's not just the building industry, either. 90_ cities are taking these environmentally positive approaches to design, planning and building. Portland, Seattle and Boston have said they want to be green cities. Chicago wants to be the greenest city in the world.
