In some embodiments, the user's information may be combined with other users in the building or near the user or in the same space, etc., to achieve a comfort level. For example, different users may have differing comfort level preferences; some people like it hot, and some don't. At 820, multiple user's preferences may be aggregated to generate a single state that the defined space can be set to. For example, user preferences may be averaged, the mode may be taken, a weighted average may be used, with certain values, users, etc., being given higher weights, certain values may have predefined minimums and/or maximums, and so forth. Once a comfort level is determined, this comfort level may then be used by a controller 110 that controls state change devices in the space to signal to a state change device or devices to change state of the defined space 830.
