English Abstract

Systems and methods of providing climate control and/or energy management in a structure having a networking thermostat. In some example embodiments the network is used to monitor a geographic location of a user device associated with a user of the structure. The monitoring may be performed to determine the location relative to a destination located apart from the structure. The network is used to control a set point of the thermostat based on the location. Additionally or alternatively, the monitoring may be performed to determine time period(s) during which the structure is unoccupied and the thermostat is set at a first set point. Energy savings that could have been realized by changing the first set point to a second set point are estimated and provided to the user.


French Abstract

Des systèmes et des méthodes permettent le contrôle du climat et la gestion de l'énergie dans une structure comprenant un thermostat en réseau. Dans certaines réalisations exemplaires, le réseau sert à surveiller l'emplacement géographique d'un dispositif utilisateur associé à l'utilisateur de la structure. La surveillance peut être exécutée pour déterminer l'emplacement relativement à une destination située à l'écart de la structure. Le réseau est utilisé pour contrôler un point de consigne du thermostat en fonction de l'emplacement. De plus ou autrement, la surveillance peut être exécutée pour déterminer les périodes pendant lesquelles la structure est inoccupée et le thermostat est réglé à un premier point de consigne. Les économies d'énergie qui pourraient être obtenues en réglant le premier point de consigne à un deuxième point de consigne sont estimées et fournies à l'utilisateur.


Note: Claims are shown in the official language in which they were submitted.

CLAIMS:
1. A system for providing climate control in a structure, the system
comprising:
a thermostat of the structure, the thermostat connected with a network; and
one or more processors connected with the thermostat through the network and
configured to:
monitor a user device associated with a user of the structure, the
monitoring performed to obtain a history of geographic locations visited and
remained at by the user for longer than a predefined time apart from the
structure;
based on the history, identify one of the visited locations as a destination;
determine a current geographic location of the user device in relation to
the destination; and
determine a set point for the thermostat based on the current geographic
location.
2. The system of claim 1, wherein the one or more processors are configured
to
control the thermostat via the network, based on the determined set point.
3. The system of claim 1 or 2, wherein the one or more processors are
configured
to:
store a historical average duration of visits by the user device to the
destination; and
using the historical average duration and a distance between the structure and

the destination, determine a setback temperature at which to set the
thermostat set
point for a future visit to the destination.
4. The system of any one of claims 1 to 3, wherein the one or more
processors are
configured to set the thermostat to a predetermined setback temperature via
the
network when the user device is determined to be arriving at the destination.
22

5. The system of any one of claims 1 to 4, wherein the one or more
processors are
configured to determine the set point based on a breakeven duration, the
breakeven
duration based on one or more thermal properties of the structure and/or a
type of
climate control equipment in the structure.
6. The system of claim 5, wherein the one or more processors are configured
to
obtain the breakeven duration from a plurality of breakeven durations
predetermined for
a plurality of outdoor temperatures and a plurality of setback amounts.
7. The system of any one of claims 1 to 6, wherein the one or more
processors are
configured to determine the set point for the thermostat based on the
geographic
location of the user device relative to one or more of the following: a
setback ring
between the structure and the destination, a traffic pattern, and a sub-
destination
associated by the system with the destination.
8 A system-performed method of providing climate control in a structure,
the
method comprising:
monitoring a user device associated with a user of the structure, the
monitoring
performed to obtain a history of geographic locations visited and remained at
by the
user for longer than a predefined time apart from the structure;
based on the history, identifying one of the visited locations as a
destination;
determining a current geographic location of the user device in relation to
the
destination; and
using a network through which the system is connected with a thermostat of the

structure, controlling a set point of the thermostat based on the current
geographic
location.
23

9. The method of claim 8, comprising:
storing a historical average duration of visits by the user device to the
destination; and
determining a setback temperature at which to set the thermostat set point for
a
future visit to the destination, the determining performed using the
historical average
duration and a distance between the structure and the destination.
10. The method of claim 8 or 9, comprising setting the thermostat to a
predetermined
setback temperature via the network when the user device is determined to be
arriving
at the destination.
11. The method of any one of c'aims 8 to 10, comprising:
determining a breakeven duration based on one or more thermal properties of
the structure and/or a type of climate control equipment in the structure; and

determining the thermostat set point based on the breakeven duration.
12. The method of claim 11, further comprising predetermining a plurality
of
breakeven durations for the structure based on a plurality of outdoor
temperatures and
setback amounts.
13. The method of any one of claims 8 to 12, further comprising determining
a set
point of the thermostat based on the geographic location of the user device
relative to
one or more of the following: a setback ring between the structure and the
destination, a
traffic pattern, and a sub-destination associated by the system with the
destination.
