Dynamic control of a building fluid distribution system

This paper presents a method for dynamic pressure control of a building fluid distribution system. This control method is currently implemented as part of a remote centralized service of existing building automation systems (BAS). The framework, however, fits very well for future implementation as a stand-alone web application. The control topology first identifies the pressure model of the distribution system and then employs a predictive dynamic control model to minimize pressure requirements. The energy savings potential using this control methodology is substantial. Implementation at test sites has shown a reduction in energy (kWh) costs by as much as 50% as compared to the conventional fixed pressure control strategy. The control system also reduces noise and has fault detection and diagnostics capability.
