Our current Research Interest lies in the Energy Management System (EMS) which is one of the high-level control methods available in any advanced building. An EMS is able to access a wide variety of â€œsensorâ€?data and use this data to direct various types of control actions. The concept is yet to be received well in our industry and validation of the same is a subject of a lot of discussion. As a results of this study, better understanding of modern building specially on controls side will be gained and future energy code may have better enforcement on soft energy efficiency measures. The EMS replicates the functionality of many of the existing high-level control objects in Energy Plus. Similar to the Availability Manager objects, the EMS can turn on and off pumps and fans. Similar to the Demand Manager objects, the EMS can turn on and off lights and electric equipment, change the set points on zone thermostats, and dispatch on-site generation. Similar to the Set point Manager objects, the EMS can change the set points on system nodes. Similar to the Plant Equipment Operation objects, the EMS can turn on and off supply-side heating, cooling, and heat rejection equipment, i.e., boilers, chillers, cooling towers, etc. Similar to the ElectricLoadCenter:Distribution, the EMS can turn on and off on-site generation equipment.
The above functionality when clubbed with an external Interface allows coupling Energy Plus to the Building Controls Virtual Test Bed (BCVTB). The BCVTB is a software environment that allows expert users to couple different simulation programs for distributed simulation or for a real-time simulation that is connected to a building control system. The BCVTB allows simulation of the building envelope and HVAC system in Energy Plus and the control logic in MATLAB/Simulink, while exchanging data between the two programs as they simulate.
