Abstract: A computer based equipment scheduling system uses activity definition data to schedule equipment. The method may be carried out by a networked computer system that receives activity definition data representing an activity, such as a volleyball game or board meeting, that occurs in a building. This data is stored in a database for use by multiple nodes. The activity definition data may include text or graphical data indicating an activity name, data representing a list of zones that the activity will affect and data representing the mode of possible operation of each building zone affected by the activity. The method also includes assigning zone mode data to the activity data for use in controlling building resources and then automatically controlling the building resources to attain a zone mode of operation assigned to the activity definition data.
