The advances in object technology offer alternatives in system modeling within the context of a building and its environment. The application is described of the object technology underlying the development of the infra-structure of the Energy Kernel System, an object-oriented environment for simulation model creation, maintenance and validation. The main features include the following: the abstraction and encapsulation of data in building energy modeling. The outcome of this leads to the core element--the EKS taxonomy; the development of knowledge identification and representation mechanisms to enable the compatibility and extensibility, while ensuring the legality, of the physical reality; the concept of "atomic" and "modular" approaches that enable the creation of application programs of completely different modeling system architectures.
