RESUMO

Among the trends of rational use of resources, especially energy, and the need to ensure productivity and quality in the implementation of productive activities, there is the concept of intelligent building. This environment materializes the concept of integrating building systems, powering the optimization of resources and the efficiency of human labor. In this context, conceptual approaches that are based on systems of discreet events and techniques, which are derived from the Petri nets, have been introduced as an effective alternative to modeling and analysis of solutions of building systems integration. A significant result of these initiatives are the proposed methods for modeling and the analysis of strategies for air conditioning systems management using a hybrid approach where the aspects of systems of discreet events and the variables of continuing dynamic are considered. However, the existing methods and approaches are limited to their specific implementation solutions, such as air conditioning systems with continuous volume of air. Thus, this work introduces an extension of these approaches to model and analyze the building automation solutions that include air conditioning systems with variable volume of air. The efficiency of this method in the design and validation of these solutions is illustrated through a case study.
