1. A method of managing a building load reduction of a plurality of loads within a building, comprising:
- assigning one or more loads of the plurality of loads to a logical group of a plurality of logical groups;
assigning a sensitivity coefficient to each logical group of the plurality of logical groups, wherein the sensitivity coefficient is directly proportional to an impact on occupants in the building to changes in a power load of the logical group;
determining a baseline load for each of the logical groups;
receiving a power reduction demand response; and
reducing a power load of each logical group based upon the sensitivity coefficient and the baseline load of the logical group;
whereinassigning the sensitivity coefficient comprises determining an impact of the power load of the logical group to users who utilize the loads of the logical group, wherein the sensitivity coefficient for each logical group is inversely related to a loss in productivity of an organization for a unit percentage reduction in a lighting load of the logical group.

11. A method of managing a building load reduction of a plurality of loads within a building, comprising:
-
assigning one or more loads of the plurality of loads to a logical group of a plurality of logical groups; assigning a sensitivity coefficient to each logical group of the plurality of logical groups, wherein the sensitivity coefficient is directly proportional to an impact on occupants in the building to changes in a power load of the logical group; determining a baseline load for each of the logical groups; receiving a power reduction demand response; reducing a power load of each logical group based upon the sensitivity coefficient and the baseline load of the logical group; and specifying a minimum power load for each of the logical groups, wherein the minimum power load preempts the reduced load of each logical group based upon at least one of the sensitivity coefficient and the baseline power load of the logical group, and limits the reduction of the power load of the logical group.

12. A method of managing a building load reduction of a plurality of loads within a building, comprising:
-
assigning one or more loads of the plurality of loads to a logical group of a plurality of logical groups; assigning a sensitivity coefficient to each logical group of the plurality of logical groups, wherein the sensitivity coefficient is directly proportional to an impact on occupants in the building to changes in a power load of the logical group; determining a baseline load for each of the logical groups; receiving a power reduction demand response; reducing a power load of each logical group based upon the sensitivity coefficient and the baseline load of the logical group; and sensing occupancy of areas of each logical group, and further comprising accelerating reducing the load to logical groups that do not sense occupancy upon receiving the power reduction demand response.

13. A method of managing a building load reduction of a plurality of loads within a building, comprising:
-
assigning one or more loads of the plurality of loads to a logical group of a plurality of logical groups; assigning a sensitivity coefficient to each logical group of the plurality of logical groups, wherein the sensitivity coefficient is directly proportional to an impact on occupants in the building to changes in a power load of the logical group; determining a baseline load for each of the logical groups; receiving a power reduction demand response; reducing a power load of each logical group based upon the sensitivity coefficient and the baseline load of the logical group; and sensing occupancy of areas of each logical group, initiating an occupancy timer upon sensing occupancy and further comprising reducing the load to a logical group upon receiving the power reduction demand response at a first rate if received during a time period of the occupancy timer, and reducing the load to the logical group upon receiving the power reduction demand response at a second rate if received after the time period of the occupancy timer, wherein the second rate is faster than the first rate.
