Abstract: A method for providing control to a building zone uses a building automation system and a portable wireless device located within the building zone. The method includes the step of identifying the portable wireless device using wireless communications. The method further includes retrieving information from a memory device specific to the identified portable wireless device. The retrieved information comprises a user preference relating to the building automation system. The method further includes adjusting a parameter of the building automation system based on the retrieved information.

Abstract: An HVAC control system configured to control the environment of a building zone includes a means for determining a number of people occupying the building zone and a means for determining properties of other heat transferring objects located within the building zone. The HVAC control system may also include a controller, the controller being configured to compute a projected heat gain in a building zone based on the determined number of people occupying the building zone and the determined properties of the other heat transferring objects located within the building zone. The controller may use the computed projected heat gain to determine a zone ventilation setpoint for the building zone.
