In this paper an abstract model for adaptation of enterprise technologies in heterogeneous networks of small devices is proposed. The model is based on hierarchical multi- tier approach for better manageability and administration. Its structure allows not only separation between business and presentation logic, but also separation of enterprise and automation functions. Thus, changes in business and automation logics do not affect the user. The actual distribution of functions appears on the service and automation tiers. The level of abstraction of the model allows its usage in various environments - home and office automation, industry, medicine, agriculture. In the paper an experimental application of the presented model for an effective management of HVAC (heating, ventilation and air conditioning) systems in buildings is discussed. subsystems. The key goal of the work, presented in the paper, is the analysis of the latest off-the-shelf technologies in business information systems and their possible adaptation in distributed automation, based on controllers with embedded communication facilities. For this purpose, a model of information flow and representation in distributed automation systems is developed, employing the standards of e-business, working on the web. An experimental application of the presented model for an effective management of Heating, Ventilation, and Air-Conditioning (HVAC) systems in residential buildings is proposed. The limited resources of the embedded devices as well as the dynamic nature of building's automation networks are impending factors for the adaptation of web services into the systems. The rest of the paper is organized as follows:
