The fact that all respondents marked "personal research" as a source of sustainable building information indicates that they all have enough personal interest in this area to take some time to educate themselves about it. Respondents specifically cited Internet research, research for a Ph.D. on the topic, and research for curriculum development. One way that people commonly educate themselves is by reading, so it is not surprising that "media" was the second most common source of information marked by respondents (68%). Several respondents specifically cited Environmental Building News as a valuable source of information.

Approximately one-quarter of respondents marked "continuing education workshops" (28%), "co-workers" (28%), and/or "courses" (24%) as sources of information. Only the two developers indicated that their clients have been sources of information on sustainable building. A couple of respondents listed "conferences" as another important information source. And a contractor wrote that he has been educated by architects and engineers he works with.
