Exergy Efficiency Definitions for Manufacturing Processes

, 2011
The original application of thermodynamic metrics for manufacturing processes has been under development throughout the last decade. The metrics are based on the second law of thermodynamics. Therefore, the exergy value of both input and output streams is used to quantify them.

Exergy performance as a measure of building efficiency

, 2013
Energy Performance (EP) of buildings is expressed by indices. They are representative of primary energy use, or final energy use, or carbon dioxide equivalent emissions. The criterions of indices determination, currently used in calculation procedures, don’t actually seem to meet the needs of check energy resources and related environmental impacts ...
