*Ta* = indoor air temperature (◦C), and

*Tmr* = mean radiant temperature (◦C).

The value of *A* can be found in Table 14 as a function of the relative air speed, *vr*.

**Table 14.** Parameters of WFG.


Figure 15 illustrates the indoor relative humidity (*RH*), the surface temperature of indoor surfaces, and the MRT calculated according to Equation (4). The WFG panel temperatures (*TWFG, TWFG-TP*) contribute to cooling the mean radiant temperature down to 20 ◦C when the energy management system is in operation. *TWFG* was lower than *TWFG-TP* because the mass flow rate through the transparent panels was set to *m˙* = 2 L/min m2, and through the translucent interior partitions, it was *m˙* = 1 L/min m2. Another reason to explain the temperature difference was that each transparent WFG has its circulating device, whereas the translucent panels share the same circulating device. The former has proven to be more effective in delivering the cold from the heat pump than the latter. Floor, opaque walls, and ceiling temperatures (*Tfloor, Twall, Tceiling*) are taken into account with their angle factors, which are calculated according to Equation (5).
