Abstract
This paper proposes a method of knowledge acquisition about building environmental system from a list of measurement points in a Building Energy Management System (BEMS). The final goals is to construct a robust and flexible method of detecting and diagnosing faults in architectural environmental from BEMS data. A logical grammar is employed to parse the name of measurement point and translate it into the logical expression. A set of logical expression represents a part of architectural environmental system.Together with the ontology of physical and empirical laws about HVAC, the set is used for detection and diagnosis of faults.
