hen I heard this, it felt to me a lot like a situation we face with some regularity in green building. We are racing to make our buildings safer, healthier for occupants, less-polluting, and lower carbon. But we are behind in that race. For example, we have been paying serious attention to the health effects of building materials on indoor air quality for only about 20 years. We have been inventing new chemicals that affect our indoor air quality for well over 100 years.
Unfortunately for the builder, homeowner, or renter who simply wants some reliable advice on what to worry about from an environmental perspective, and what not to worry about, things sometimes change or crop up unexpectedly. And we’re not usually completely ready with a seamless hot swap. Remember when compact fluorescent bulbs first came out? Remember the first low-flow toilets? Best forget them.
