ROOM THERMAL COMFORT MONITOR
First Claim
1. A method for zone thermal comfort monitoring comprising:
- obtaining sensor data of a zone;
computing a thermal comfort level information from the sensor data;
thresholding the thermal comfort level information into one or more thermal comfort level categories; and
outputting a thermal comfort level visualization for the zone in accordance with the one or more thermal comfort level categories.

Abstract
A system for monitoring thermal comfort of a room. Sensor data concerning temperature, relative humidity, air speed and air flow may be collected from the room. The sensor data may provide thermal comfort level information about the room. The level information may be quantified in terms of a thermal comfort level index, such as a predicted mean vote, which can be used to identify one or more thermal comfort levels in the room with a numerical measure. The one or more levels may be portrayed as a visualization in terms of a 3D plot of temperature, humidity and air speed, several 2D plots, a dashboard, or other items. The visualization may easily enable one to see where setpoint adjustment is possible in a heating, ventilation and air conditioning system to save energy while maintaining thermal comfort acceptable to occupants in the room, whether during a heating season or a cooling season.

15. A system for zone thermal comfort monitoring comprising:
-
one or more sensors for determining temperature, relative humidity and air speed in a zone; a first mechanism for calculating a thermal comfort level index from the temperature, relative humidity and/or air speed in the zone; a second mechanism for setting one or more thresholds of the thermal comfort level index to indicate one or more thermal comfort levels; and a third mechanism for adjusting the thermal comfort level index to reduce cooling or heating energy and still maintain a desired thermal comfort level of the one or more thermal comfort levels. - View Dependent Claims (16, 17, 18)

19. An approach for room thermal comfort monitoring, comprising:
-
detecting temperature, relative humidity, air speed, and/or radiant temperature; determining a metabolic rate and/or clothing level of one or more occupants in the room; and computing a thermal sensation index of the room from the temperature in the room, relative humidity in the room, air speed in the room, and the metabolic rate and/or clothing level of the one or more occupants in the room. - View Dependent Claims (20)
