Building automation system with geo-fencing

A method for providing building automation, the method comprising:

• determining, by a building automation controller implemented in circuitry and based on a first message from a first mobile device, whether the first mobile device is positioned within a first geofence configured for a first sensitivity of a first user's location as determined by the first mobile device relative to a building;
• determining, by the building automation controller and based on a second message from a second mobile device, whether the second mobile device is positioned within a second geofence configured for a second sensitivity of a second user's location as determined by the second mobile device relative to the building, wherein the first sensitivity is higher than the second sensitivity;
• and
• adjusting, by the building automation controller, an operating parameter at the building based on the determination of whether the first mobile device is positioned within the first geofence and on the determination of whether the second mobile device is positioned within the second geofence.

A system for providing building automation, the system comprising:

• a first mobile device comprising:
• a first memory for storing a first user profile for a first user, the first user profile specifying a first geofence configured for a first sensitivity of the first user's location as determined by the first mobile device relative to a building;
• and
• a first controller implemented in circuitry and configured to output a first message indicating whether the first mobile device is positioned within the first geofence;
• a second mobile device comprising:
• a second memory for storing a second profile for a second user, the second profile specifying a second geofence configured for a second sensitivity of the second user's location as determined by the second mobile device relative to the building, wherein the first sensitivity is higher than the second sensitivity;
• and
• a second controller implemented in circuitry and configured to output a second message indicating whether the second mobile device is positioned within the second geofence;
• and
• a building automation controller implemented in circuitry and configured to adjust an operating parameter at the building based on the first message and the second message.
