Ambient intelligence has the potential to profoundly affect future building operations. Recent breakthroughs in wireless sensor network technology will permit 1) highly flexible location of sensors and actuators, 2) increased numbers and types of sensors informing more highly distributed control systems, 3) occupants’ involvement in control loops, 4) demand responsive electricity management, 5) integration among now-separate building systems, and 6) the adoption of mixed-mode and other new types of air conditioning systems that require more sensor information to operate efficiently. This chapter describes the issues with current building automation technology, assesses how some applications of wireless sensor technology can increase the quality of control and improve energy efficiency, and suggests opportunities for future development.
