Abstract: A method for conditioning a building includes drawing unconditioned outside air at a first flow rate through a dedicated outdoor air system unit, conditioning the outside air by the dedicated outdoor air system unit to conditioned air, supplying the conditioned air to a first room, and exhausting the conditioned air at a second flow rate to an exterior of the building by a kitchen exhaust fan located in a second room. The first and second rooms can be in fluid communication with a common area of the building such that the conditioned air from the first room is drawn to the second room via the common area to supply conditioned air to the common area and second room. The second flow rate can be controlled by a temperature sensor adjacent the kitchen exhaust fan.
