The Boston Green & Healthy Building Network is coordinating action among two sets of groups that advocate for changes in building codes. For several years, the Boston-based Barr Foundation had been funding public health organizations that saw unhealthy buildings as a cause of illness, and environmental groups that were focused on the ecological impact. In 2005, a senior program officer at the foundation suspected that while the causes of the two groups were different, the groups shared a common goal of establishing better building standards, and they often approached the same government officials, though they rarely worked together. So the foundation brought together the various parties to explore whether they could coordinate their efforts, share information, and develop a more unified message for policymakers.

Using information collected at the gathering, the Barr Foundation developed a social network map of the people in the room. The map clearly showed two principal clusters of dots, one representing people in health organizations and the other people in environmental organizations; it also showed that the groups were not well connected. Seeing the map of their fragmented network, the groups had an epiphany; the map mirrored their lack of coordination, and they decided to act. They formed the Boston Green & Healthy Building Network, which has subsequently increased connections and collaboration among the different groups, improved access to and relationships with, many key policy-makers in the city, and resulted in City of Boston projects that integrate green and healthy building objectives.[[#_edn1|[i]]]
