Abstract

Energy-related occupant behavior in buildings is difficult to define and quantify, yet critical to our understanding
of total building energy consumption. Part I of this two-part paper introduced the DNAS
(Drivers, Needs, Actions and Systems) framework, to standardize the description of energy-related
occupant behavior in buildings. Part II of this paper implements the DNAS framework into an XML
(eXtensible Markup Language) schema, titled ‘occupant behavior XML’ (obXML). The obXML schema is
used for the practical implementation of the DNAS framework into building simulation tools. The topology
of the DNAS framework implemented in the obXML schema has a main root element OccupantBehavior,
linking three main elements representing Buildings, Occupants and Behaviors. Using the
schema structure, the actions of turning on an air conditioner and closing blinds provide two examples of
how the schema standardizes these actions using XML. The obXML schema has inherent flexibility to
represent numerous, diverse and complex types of occupant behaviors in buildings, and it can also be
expanded to encompass new types of behaviors. The implementation of the DNAS framework into the
obXML schema will facilitate the development of occupant information modeling (OIM) by providing
interoperability between occupant behavior models and building energy modeling programs
