Well this is interesting. Holly Bik pointed me to the fact that the Clinton Global Initiative has a track on the Built Environment:About Us: The Built Environment | Clinton Global Initiative.
Not sure exactly what they do in this track but seems like a good way to get exposure for the field of microbiology of the built environment would be to get the CGI people to include discussions of microbes in their next meetings.
Their next US meeting is in June in Denver (see http://www.cgiamerica.org). Wonder if there is a way to get some microbiology included …
(Also see the 2014 working group they have on Sustainable Buildings)
