In the 1960s, commercial buildings became more isolated from the outdoor environment and were built and filled increasingly with synthetic materials. In the 1970s, concern for energy conservation drove ventilation rates down, and indoor air quality and climate problems proliferated. In the 1980s, we learned that we had to address thermal comfort, indoor air quality, and energy management in an integrated fashion. When satellite observations helped scientists confirm the seasonal appearance of the ozone hole over the Antarctic region, it became even more evident that, as the ecologists have said for decades, 'everything is connected to everything.' The corollary is: 'you can't do just one thing.'
