Unsteady-state exergy analysis on two types of building envelopes under time-varying boundary condition

, 2018
In the built environment, the thermal exergy behavior is very sensitive to the change of environmental temperature, because the temperature difference between the reservoir and a system of interest is small. Moreover, the transient characteristics become
