This paper presents the results of initial work in developing an ontology for improving information exchange and automation in building system commissioning practices. In our previous research dealing with the derivation of product models from building commissioning process models, we found that there is a need to categorize and classify information items, which are available in commissioning process descriptions. In addition, the relationship between these items should be clearly defined to establish a topological relationship between items necessary for specifying product models.
Ontology development is the way to categorize and classify domain knowledge information and items into inter-related concepts. Ontology assembles information in the form of concept hierarchies (taxonomies), axioms, and semantic relationships, which allow natural language to be presented unambiguously. A glossary (a lower form of ontology) specific to building commissioning tasks was developed as a first step. In the second step, an ontology for use in commissioning software applications was developed
