The way we build now

Vernacular building for humans evolved in much the same way that shelter evolved for birds and animals: largely by trial and error, and experience. Healthy accommodation is critical for the survival of all species, and the existence of molds and fungal spores in the air and food supply has been part of the evolutionary equation. With human intervention, the environment has been changed by the use of chemical products and the availability of cheap energy, at a rate outpacing evolutionary adaptation. The interaction of these challenges with building design and human health is significant. Relevant factors should be explored, and their effects understood, so that solutions in building can be developed before the use of fossil fuels must be abandoned altogether.
