Environmental concerns have brought energy efficiency to the forefront of research priorities. Canada currently ranks as the world's sixth largest user of primary energy. A significant portion of that energy is spent by comfort control structures that regulate temperatures and humidity in buildings; a large percentage of such control structures are installed, operated and serviced by the industrial partner for this project, Johnsons Control Inc (JCI). Current installation of building control systems suffer significantly from sensor and actuator faults, or poorly tuned control algorithms, resulting in significant wastage of energy. Development of a systematic framework that can quickly diagnose faults, and provide well tuned controllers is therefore important, both economically, and environmentally. Indeed, JCI has established an entire group, The Building Efficiency Research Group, dedicated to exploring new ways of achieving energy efficiency. In implementing fault tolerant building control, the limitations of heating and cooling equipment, the necessary start ups and shutdowns of equipment, as well as the desire to hold conditions within comfortable regions naturally requires a control framework that can handle constraints, nonlinearities, respond to uncertainties, and account for optimality, as well as the multivariable nature of the process in a systematic manner. In essence, there is a significant `energy gap' that can be bridged by well designed control and fault-handling frameworks for building control. Motivated by these considerations, this project aims at fault detection and isolation and fault-tolerant building control structures. The results are expected to significantly improve the energy efficiency of building structures leading to a positive Canada-wide impact.******

环境问题使能源效率成为研究重点的前沿。加拿大目前是世界第六大一次能源使用国。其中很大一部分能量消耗在调节建筑物温度和湿度的舒适控制结构上；此类控制结构的大部分由该项目的工业合作伙伴江森自控公司 (JCI) 安装、操作和维护。 当前安装的楼宇控制系统严重受到传感器和执行器故障或控制算法调整不当的影响，从而导致大量能源浪费。 因此，开发能够快速诊断故障并提供良好调整的控制器的系统框架无论在经济上还是环境上都非常重要。事实上，JCI 已经成立了一个完整的小组，即建筑能效研究小组，致力于探索实现能源效率的新方法。在实施容错建筑控制时，加热和冷却设备的限制、设备必要的启动和关闭以及将条件保持在舒适区域的愿望自然需要一个控制框架，该框架能够以系统的方式处理约束、非线性、响应不确定性、考虑最优性以及过程的多变量性质。 从本质上讲，存在着巨大的“能量差距”，可以通过精心设计的建筑控制控制和故障处理框架来弥补。出于这些考虑，该项目旨在故障检测和隔离以及容错建筑控制结构。预计研究结果将显着提高建筑结构的能源效率，从而在加拿大范围内产生积极的影响。******
