Subcommittees for Existing Buildings


GBI will make every effort to post dates and times for Subcommittee meetings. However, this list may not be completely up to date. The best way to find out about updates on dates and times is to join a Subcommittee as an Interested Party. To become an Interested Party, email Emily Marx, Secretariat, at emarx@thegbi.org and specify in which Subcommittees you are interested in. The public is more than welcome to participate. We look forward to your active involvement.
