We often sponsor one or more Seminars at the Society National Meetings. This is a good opportunity to let others know what TC 5.5 is doing.

We are also involved with the writing and revision of standards. In particular, TC 5.5 has had a long history of involvement in Standard 84, "Method of Testing Air-to-Air Heat/Energy Exchangers."

The subcommittee meetings are where the action is, so don't miss them. They are a good way for TC members to become more closely involved with the activities of the committee.
