Buildings are some of the largest energy consumers in the
world and yet occupants are regularly dissatisfied with the
interior environment in large part due to thermal discomfort
[7]. Studies show that given personal control over their
environment, occupants are comfortable in a much larger
range of ambient temperatures [2]. We present a personalized
control smartphone application designed with the dual
goals of increasing occupant comfort and achieving buildingwide
energy savings.
The application allows occupants to directly control the
lighting and heating/cooling in their vicinity. Using wireless
localization combined with data from existing sensors
in the building, we estimate room occupancy and use this to
dynamically adjust ventilation and air conditioning to save
energy in the building.
