Thermal Exergy Analysis of a Building

open access: yesEnergy Procedia, 2014
AbstractExergy 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.

Exergy Dynamics of Systems in Thermal or Concentration Non-Equilibrium [PDF]

open access: yesEntropy, 2017
The paper addresses the problem of the existence and quantification of the exergy of non-equilibrium systems. Assuming that both energy and exergy are a priori concepts, the Gibbs “available energy” A is calculated for arbitrary temperature or concentration distributions across the body, with an accuracy that depends only on the information one has of ...
