Simulation and optimization in the real time control of building environmental systems

Some details of the optimization work conducted over the last five years in a high rise office complex are described. The solution of the many nonlinear equations representing the building environmental system in real time necessitates very fast algorithms and complete mapping of the feasible regions. The authors experiments in this area are outlined. Models for a chilled water system and an unusual application to an existing dual duct system are given as examples of a general nonlinear approach.
