A thermostat system according to the invention includes: a central control device (typically a programmable thermostat with a processor having: a CPU, real time clock and a memory for storing a control program and data information), multiple rooms comprising a conditioned space, environmental control equipment, and multiple environmental sensors capable of sensing an environmental condition (such as temperature, humidity, or other condition). The sensors are associated with transmission means, which control transmission of sensor signals, and occupancy sensors. Each sensor measures a local environmental condition. Occupancy sensors comprise infrared or other motion sensors, light detection sensors, door opening sensors, and other such sensors that detect the presence of humans in a room of the conditioned space where its associated sensor is located. Space conditioning equipment is activated by comparison of a setpoint to a control value averaged from values of environmental conditions in occupied rooms.

An architecture for minimizing calibration effort in an IEEE 802.11 device location measurement system. The calibration technique is based upon a regression function that produces adequately accurate location information as a function of signal strength regardless of gaps in the calibration data or minimally available data. The algorithm takes a set of signal strengths from known room locations in a building and generates a function giving (x,y) as a function of signal strength, which function may then be used for the estimation of new locations. Radial basis functions, which are simple to express and compute, are used for regression. The fact that the algorithm maps signal strength to continuous location makes it possible to skip rooms during calibration, yet still evaluate the location in those rooms.

A method for authenticating a room entering person who tries to enter an area where one or more structural elements are present is determined by employing a hardware token storing attribute information of the person. A security level of each of the structural elements presently located within the area is acquired via network. The attribute information of the person is acquired from the hardware token. A present security level of the area is determined by employing the security levels of the structural elements. A present trust level of the person is determined by employing the attribute information of the person. An authenticating method of the person is determined in a manner that at least one authenticating method is selected from plural authenticating methods by employing the determined present security level of the area and the determined present trust level of the person.

Regarding rooms other than a room being targeted, a controller controls the rooms in energy-saving conditioning mode when a person is not detected in the rooms, even when the rooms are scheduled to be controlled in ordinary conditioning mode in a temperature control schedule. At this time, when the controller judges that the person has exited the room, the controller controls the targeted room in energy-saving conditioning mode, in rapid conditioning mode. As a result, the room is rapidly conditioned such that the temperature changes from an energy-saving temperature t to an ordinary set temperature by the time the person who has exited the room enters the room. As a result, unnecessary conditioning of the room set to be conditioning in ordinary conditioning mode can be reduced, and energy consumption can be reduced. In addition, comfort of the person entering the room can be ensured by prediction of the movement of the person.

To control lighting and other utilities in buildings based upon occupancy, mountable sensors are used to detect low energy radio frequencies emitted from devices, or tags, worn or carried by occupants. In a demand control system, identification (ID) codes embedded in tags worn by occupants are detected in each room by a tag sensor and may wirelessly communicate to a zonal compiler that determines zonal occupancy. The zonal occupancy count is transmitted to an interface relay that immediately adjusts the intensity and rate of the specific utility. HVAC systems may also be tied into the system to have adjustments made to the intensity and rate of ventilation as done with the lighting in this system. This system has many advantages over current systems such as not being dependent upon movement of an occupant or following the heat signature of an occupant that both may lead to false readings and delay in adjusting the specific building utility to save energy and costs.
