Thermal Exergy Analysis of a Building

Exergy analysis has been contemplated to evaluate the direct energy impact of a building on the environment. The authors’ approach is to consider the building as a “black box” that needs exergy. The surrounding and the Environment are closed systems, in thermodynamic equilibrium between them. The building is transient open system. The paper is composed of two main sections: a description of the model and the application to a building. The aim is to analyze thermodynamic interaction building – surrounding in order to estimate the input exergy, loss and especially destruction exergy.
