Abstract

Disclosed are systems and methods for adjusting environmental conditions within a physical structure comprising a plurality of linked commissioned units. One or more occupancy sensors (140-1, 150-1) produce data indicating that a designated zone has transitioned from an unoccupied state to an occupied state. A first one or more luminaires (140-2, 150-2) associated with a first one of the plurality of linked commissioned units (120D), produces a background level of illumination within a predetermined reaction period following the production of the sensor data. The first one of the plurality of linked commissioned units transmits data indicative of the state change of the designated zone, and at least a second one of the plurality of linked commissioned units receives the data indicative of the state change, and causes at least a second one or more luminaires to alter illumination.

Claims

1. A method for managing environmental conditions within a physical structure comprising a plurality of linked commissioned units, the method comprising:

one or more occupancy sensors producing data indicating that a designated zone has transitioned from an unoccupied state to an occupied state;

a first one or more luminaires associated with a first one of the plurality of linked commissioned units, producing a background level of illumination within a predetermined reaction period following the production of the sensor data;

the first one of the plurality of linked commissioned units transmitting data indicative of the state change of the designated zone; and

at least a second one of the plurality of linked commissioned units receiving the data indicative of the state change, and causing at least a second one or more luminaires to alter illumination.

2. The method of claim 1, wherein the second one of the plurality of linked commissioned units or the at least second one or more luminaires accesses a memory storing lighting scene information prior to the at least second one or more luminaires altering illumination.

3. A method for managing environmental conditions within a physical structure comprising a plurality of linked commissioned units and one or more occupancy sensors, the method comprising:

making a first determination, based on occupancy data produced by the one or more occupancy sensors, that a designated zone has transitioned from an occupied state to an unoccupied state;

monitoring additional occupancy data produced by the occupancy sensors for at least part of the duration of a hold period, and making a second determination as to whether or not the designated zone remained in the unoccupied state for the entirety of the hold period;

based on the result of the second determination, one or more luminaires of at least one of the plurality of linked commissioned units that is associated with the designated zone, fading to a first lower level of illumination over a first grace period that commences following the expiration of the hold period.

4. The method of claim 3, further comprising the steps of:

monitoring additional occupancy data produced by the occupancy sensors for at least part of the duration of the first grace period, and making a third determination as to whether or not the designated zone remained in the unoccupied state for the entirety of the first grace period; and

based on the result of the third determination, the one or more luminaires;

fading back to a previous higher level of illumination produced prior to the commencement of the first grace period, or

completing their transition to the first lower level of illumination.

5. The method of claim 4, further comprising the steps of:

monitoring additional occupancy data produced by the occupancy sensors for at least part of the duration of a prolong period, and making a fourth determination as to whether or not the designated zone remained in the unoccupied state for the entirety of the prolong period; and

based on the result of the fourth determination, the one or more luminaires;

fading back to a previous higher level of illumination produced prior to the commencement of the prolong period, or

fading to a level of illumination associated with a switched-off state over a second grace period that commences following the prolong period.

6. A method for managing environmental conditions within a physical structure comprising a plurality of linked commissioned units and one or more illumination sensors, the method comprising:

the one or more illumination sensors indicating a change in illumination in a work zone;

at least one of the plurality of commissioned units associated with the work zone and communicatively connected to the one or more sensors, receiving the indication of the change in illumination, and making a first determination as to whether or not an amount of change associated with the indication of change in illumination is greater than a preset amount;

based on the first determination, the at least one of the plurality of commissioned units accessing the output of the one or more illumination sensors, and making a second determination as to whether or not a level of illumination in the work zone is at or above a preset level of illumination;

at least one luminaire within the work zone transitioning to;

providing a predetermined minimum level of illumination over a first fade period if the second determination indicates the level of illumination in the work zone as being at or above the preset level of illumination;

or

providing a predetermined maximum level of illumination over a second fade period if the second determination indicates the level of illumination in the work zone as being below the preset level of illumination.

7. A system for managing environmental conditions within a physical structure comprising a plurality of linked commissioned units, the system comprising:

one or more occupancy sensors producing data indicating that a designated zone has transitioned from an unoccupied state to an occupied state;

a first one or more luminaires associated with a first one of the plurality of linked commissioned units, producing a background level of illumination within a predetermined reaction period following the production of the sensor data, wherein the first one of the plurality of linked commissioned units transmits data indicative of the state change of the designated zone; and

at least a second one of the plurality of linked commissioned units receiving the data indicative of the state change, and causing at least a second one or more luminaires to alter illumination.

8. The system of claim 7, wherein the second one of the plurality of linked commissioned units or the at least second one or more luminaires accesses a memory storing lighting scene information prior to the at least second one or more luminaires altering illumination.

9. A system for managing environmental conditions within a physical structure, the system comprising:

one or more illumination sensors indicating a change in illumination in a work zone within the physical structure;

a plurality of linked commissioned units, wherein at least one of the units is associated with the work zone, is communicatively connected to the one or more sensors, and the at least one unit;

receives the indication of the change in illumination and makes a first determination as to whether or not an amount of change associated with the indication of change in illumination is greater than a preset amount; and

based on the first determination, accesses the output of the one or more illumination sensors, and makes a second determination as to whether or not a level of illumination in the work zone is at or above a preset level of illumination; and

at least one luminaire within the work zone transitioning to;

providing a predetermined minimum level of illumination over a first fade period if the second determination indicates the level of illumination in the work zone as being at or above the preset level of illumination;

or

providing a predetermined maximum level of illumination over a second fade period if the second determination indicates the level of illumination in the work zone as being below the preset level of illumination.
