Hvac management system and method

A method of managing a heating, ventilation and air conditioning (HVAC) system comprising:

• controlling an atmospheric condition of a space with a plurality of air manipulation components;
• approximating a number of occupants present in the space based on a number of mobile devices located within the space with a sensor assembly, wherein approximating the number of occupants comprises detecting communication data associated with a mobile device with a receiver of the sensor assembly;
• measuring a temperature of an area of the space proximate the sensor assembly with a temperature sensor of the sensor assembly;
• sending data comprising the temperature measured and the number of mobile devices from the sensor assembly to a controller in operative communication with the sensor assembly and the plurality of air manipulation components;
• and
• controlling the plurality of air manipulation components with the controller based on the data received from the sensor assembly.
