- •
An exergy-based energy efficiency method called PeXa is developed.
- •
PeXa combines exergy analysis and primary energy analysis.
- •
PeXa uses exergy analysis inside a process and primary energy based factors for the surrounding society.
- •
In some cases exergy analysis and PeXa will give different results assuming that the objective is to consider the primary energy effects of society.
