Fortunately, at least in the U.S., our building codes for new and renovated buildings help ensure that, over time, most of our buildings will be well-insulated.

But, I don't know how well current codes ensure that all aspects of IAQ are reasonably safe, particularly in residences. I'd need to check, but not sure they seriously address prolonged, elevated exposure to VOCs. I fear that decades from now, we'll learn we harmed a lot of people via prolonged exposure.
