Summary on Grant Application Form |

Stochastic mathematical models which predict building behaviour can offer a range of uses to aid the management and operation of facilities. This research is aimed at developing such a model-based approach to buildings management. An on-line dynamic model which describes the behaviour of a full-scale multi-zone air conditioned test suite and HVAC plant will be constructed, and its properties investigated. Off-line stochastic models already developed by the applicants have given good long- and short-range predictions of zone temperature and relative humidity; this proposal will extend the modelling to an on-line recursive form. As part of this modelling the potential of thermo-physical simulation as a design tool during the modelling will be investigated and developed.The feasibility of employing the model for three uses will be studied as part of this proposal: self-commissioning, fault tolerance and control. Self-commissioning and adaptive abilities of the model will be assessed by altering levels of zone effects/disturbances and then assessing the models predictive performance. Using analytical redundancy techniques, the model will be utilised for fault diagnosis, where its ability to detect and isolate deliberately induced faults will be assessed. The control potential of the model will be investigated with reference to a freely cooled naturally ventilated system; advanced control (GPC) for the temperature loop will be implemented and compared with the performance of standard PI control.
