Zone based system for altering temperature setpoints

An energy management system comprising:

• a database configured to store site data received from a residential site using a wireless home energy network, wherein the residential site includes a thermostat accessible to the wireless home energy network;
• a processor operably coupled to the database and configured to access the site data and:
• detect a current temperature set-point of the thermostat at the residential site;
• detect a current operating mode of a HVAC system operably coupled to the thermostat;
• detect a distance between a location reporting device and the residential site;
• detect a current zone from a plurality of zones operably associated with the residential site using the distance;
• detect a percentage value associated with the current zone for changing the current temperature set-point;
• determine an updated thermostat set-point based on the current operating mode of the HVAC system and the current temperature set-point and the percentage value;
• and
• initiate generation of a control action including the updated thermostat set-point to be communicated to the residential site.
