TC 7.5 currently has four application-focused subcommittees, which form the backbone of the committee's activities: building operation dynamics, fault detection and diagnostics, enabling technologies, and building/utility interface. The enabling technologies subcommittee grew out of the original wireless subcommittee in 2013. We expect that the subcommittees will continue to respond as these fields become more mature and results of research become commonplace in HVAC&R practice and as the interests of committee members change over time. The key constant, however, will be a focus on smart building systems. Read below about these subcommittees and check the Home page for meeting times.
