This thesis is concerned with improving the integrity and applicability of building energy management systems(BEMS) simulation tools. The present work attempts to overcome certain inadequacies of contemporary simulation applications with respect to environmental control systems, by developing novel building control systems modelling schemes. These schemes are then integrated within a state-of-the-art simulation environment so that they can be employed in practice. After reviewing the existing techniques and various approaches to control systems design and appraisal,a taxonomy of building control system entities grouped in terms of logical, temporal and spatial element, is presented. This taxonomy is subsequently used to identify the models, algorithms, and features comprising a comprehensive modelling environment. Schemes for improving system integrity and applicability are presented based upon a simulation approach which treats the building fabric and associated plant sy stems as an integrated dynamic system. These schemes facilitate the modelling of advanced BEMS control structure and strategies, including: - hierarchical (systems level and zone-level) control systems; - single input, single output (SISO) and multiple input, multiple output (MIMO) systems; - advanced BEMS controller algorithms; - simulated-assisted control strategies based on advanced simulation time-step control techniques. The installation of the developed schemes within a whole building simulation environment, ESP-r, is also presented. Issues related to verification of the developed schemes are subsequently discussed. Users of control system simulation programs are identified and categorised. Typical applications of the new control modelling features are demonstrated in terms of these user groups. The applications are based on both research and consultancy projects. Finally, the future work required to increase the applicability and accuracy of building control simulation tools is elaborated in terms of the required integration with other technical subsystems and related computer-aided design tools.
