Exergy analysis is used to evaluate the thermodynamic performance
of processes, including energy conversion and supply systems. This often
involves the calculation of the exergy of heat, at a temperature either above or
below the environmental temperature (T0). The exergy of ‘cold’, i.e., heat at
T < T0, is less used and therefore sometimes also less understood. This paper
broadens the understanding of the exergy of cold by discussing the theory and
giving two useful examples illustrating the added value of exergy when
considering cold: The regasification of Liquefied Natural Gas (LNG) and the
exergy demand of cooling in buildings.@en
