1. A system, comprising:
- a gateway device installed at a building;
a plurality of wireless node devices installed in a plurality of rooms in the building, a first of the plurality of wireless node devices installed in a first of the plurality of rooms in the building, the first of the plurality of wireless node devices receiving sensor data for wireless delivery to the gateway device for forwarding to a location remote from the building, the CO2 sensor data based on measurements by a CO2 sensor in the first of the plurality of rooms in the building; and
a host system at the location remote from the building, the host system receiving the CO2 sensor data from the gateway device, performing an assessment using the received CO2 sensor data of an air quality level of the first of the plurality of rooms in the building due to occupancy of the first of the plurality of rooms to determine whether the air quality level of the first of the plurality of rooms has hit a level of variance relative to a target air quality level during a time period covered by a reservation of the first of the plurality of rooms, the host system transmitting, in response to the assessment, one or more response messages to the gateway device for wireless delivery to a second of the plurality of wireless node devices, wherein the one or more response messages enable the second of the plurality of wireless node devices to generate a control signal that is transmitted to an HVAC system component used to govern the air quality level of the first of the plurality of rooms, the HVAC system component using the received control signal to adjust the air quality level in the first of the plurality of rooms during at least part of the time period covered by the reservation.

Abstract
A wireless sensor network at a monitored location can be configured to generate sensor channel(s) of data to assess operational conditions at the monitored location. Inputs based on the sensor channel(s) of data are provided to a host system for analysis of a demand to one or more resources at the monitored location. Response messages can be generated based on the demand analysis and transmitted to actuator(s) at the monitored location to effect an adjustment to the operational conditions.

5. A method, comprising:
-
receiving, by a host system at a location remote from a building, CO2 sensor data from a gateway device installed at the building, the CO2 sensor data based on measurements by a CO2 sensor in a first of a plurality of wireless node devices installed in a first of a plurality of rooms at the building, the first of the plurality of wireless node devices delivering the CO2 sensor data to the gateway device via wireless communication; performing, by the host system using the received CO2 sensor data, an assessment of an air quality level of the first of the plurality of rooms due to occupancy of the first of the plurality of rooms to determine whether the air quality level of the first of the plurality of rooms has hit a level of variance relative to a target air quality level during a time period covered by a reservation of the first of the plurality of rooms; and transmitting, by the host system in response to the assessment, one or more response messages to the gateway device for wireless delivery to a second of the plurality of wireless node devices, wherein the one or more response messages enable the second of the plurality of wireless node devices to generate a control signal that is transmitted to an HVAC system component used to govern the air quality level of the first of the plurality of rooms, the HVAC system component using the received control signal to adjust the air quality level in the first of the plurality of rooms during at least part of the time period covered by the reservation. - View Dependent Claims (6, 7, 8, 12, 13, 14)
