They have us surrounded. Even inside the spaces we build for ourselves — like homes and offices — we are a tiny minority. Invisible bacteria, fungi, and viruses outnumber us by orders of magnitude.
We will always be outnumbered, but we may have a say in which microbes we’re surrounded by, according to a new study that’s one of the first to investigate how building design influences the microbial diversity of indoor spaces. “Design choices at the level of a whole building make a really big impact on the types of invisible organisms that you see in a room,” said microbial ecologist Jessica Green, an author of the new study. The work is part of an emerging body research suggesting that design decisions — from the architect’s blueprint to the choice of ventilation system to the materials picked by the interior designer — help shape the microbes in our midst.
