Simulations coupling a DOE medium office reference building in EnergyPlus building simulation software and a prototype controller in Matlab were performed. Various aspects of the developed control technology were evaluated and verified through both simulations and testbed implementations. The external services provide communication capability to entities outside of the building for grid interaction and remote access. The facility level services connect to the zones through a backbone network, handle supervisory level information and controls, and thus facilitate building-wide scalability. The zone-level service includes the control algorithms described above as well as the corresponding interfaces, profiles, sensors and actuators to realize the zone controller. Three levels of services are defined in the architecture: external services, facility level services and zone level services. To address building-wide scalability, a system architecture was developed for the zone-based control technology. The thermostat control algorithm is based on a well-established thermal comfort model and formulated as a root-finding problem to dynamically determine the optimal thermostat setpoint for both energy savings and improved thermal comfort. It is formulated into an optimization problem with minimizing lighting-related energy consumptions as the objective and delivering adequate task light and preventing daylight glare as the constraints. The lighting load balancing algorithm adopts a model-based closed-loop control approach to more » determine the optimal electric light and venetian blind settings. The control framework contains two key algorithms: 1) the lighting load balancing algorithm and 2) the thermostat control algorithm. The control framework is designed following a modular, scalable and flexible architecture to facilitate easy integration with exiting building management systems. The developed technology is a zone-based control framework that minimizes energy usage while maintaining occupants’ visual and thermal comfort through control of electric lights, motorized venetian blinds and thermostats.
This project aims to develop an integrated control solution for enhanced energy efficiency and user comfort in commercial buildings.
