Energy Saving and Value Added Sevices:
Controlling Intelligent Buildings Using a Multi-Agent Systems Approach
In a de-regulated market the distribution utilities will compete with
added value for the customer in addition to the delivery of energy. We
describe a system consisting of a collection of software agents that monitor
and control an office building. It uses the existing power lines for communication
between the agents and the electrical devices of the building, i.e., sensors
and actuators for lights, heating, ventilation, etc. The objectives are
both energy saving, and increasing customer satisfaction through value
added services. Energy saving is realized, e.g., by lights being automatically
switched off, and room temperature being lowered in empty rooms. Increased
customer satisfaction is realized, e.g., by adapting temperature and light
intensity according to each person's personal preferences. We present
initial results from simulation experiments of an office building and
its staff. Different user profiles are modeled in terms of their energy
consuming behavior, e.g., their tendency to put out the light when leaving
a room, and to adjust the temperature when leaving and entering the building.
The energy consumption when using the system is compared to that of not
using the system. Our simulations indicate that significant savings, up
to 40 per cent, can be achieved.
