Building HVAC control knowledge data schema – Towards a unified representation of control system knowledge
Abstract Building control systems for heating, ventilation, and air conditioning (HVAC) play a key role in realizing the functionality and operation of building systems and components. Building control knowledge (BCK) is the logic and algorithms embedded throughout building control system. There are different methods to represent the BCK. These methods differ in the selection of BCK representing elements and the format of those elements. There is a lack of standard data schema, for storing, retrieving, and reusing structured BCK. In this study, a modular data schema is created for BCK representation. The data schema contains eleven representing elements, i.e., control module name, operation mode, system schematic, control flow diagram, data point, alarm, parameter, control sequence, function, and programming code. Each element is defined with specific attributes. This data schema is evaluated through a case study demonstration. The demonstration shows a new way to represent the BCK with standard formats.
Highlights Introduced a process to modularize building control knowledge (BCK) representation Identified a standard list of BCK representing elements Defined the data attributes for each BCK representing element Demonstrated the new method of representing BCK in a case study
