The field has accelerated somewhat in recent years, with significant funding from the Alfred P. Sloan Foundation[3] and with the increase attention being given to microbiomes and communities of microbes generally.
The American Academy of Microbiology had a colloquium on this topic in September 2015 and published a report "Microbiology of Built Environments".[6]
A 2016 paper by Brent Stephens [7] highlights some of the key findings of studies of "microbiomes of the indoor environment". These key findings include those listed below:
"Indoor spaces often harbor unique microbial communities"
"Indoor bacterial communities often originate from indoor sources."
"Humans are also major sources of bacteria to indoor air"
"Building design and operation can influence indoor microbial communities."
The microbiomes of the built environment are being studied for multiple reasons including how they may impact the health of humans and other organisms occupying the built environment but also some non health reasons such as diagnostics of building properties, for forensic application, impact on food production, impact on built environment function, and more.
