*4.1. Analysis of the Reference Cabin*

The reference glazing is considered a high-performance transparent envelope. It is made up of glass panes with coatings and gas cavities. Figure 14 illustrates real data and simulated indoor temperatures of the Reference cabin. In both measured and simulated curves, the interior peak temperature is slightly above 40 ◦C between 03:00 and 10:00 on 23 July 2018. Equation (24) represents the mean error (ME), which is the difference between the measured value and simulation results. Equation (25) represents the mean percentage error (MPE), with a total number of measurements of *n* = 1440.

$$ME = \frac{1}{n} \sum\_{i=1}^{n} |T\_{Si} - T\_{Ri}|\_{\nu} \tag{24}$$

$$MPE = \frac{1}{n} \sum\_{i=1}^{n} \left| \frac{T\_{Si} - T\_{Ri}}{T\_{Ri}} \right| 100. \tag{25}$$

where *TSi* is the simulated value, and *TRi* is the measured value. By computing ME and MPE, the sample summer day, 23 July 2018, MEs and MPEs of the indoor temperature of the Reference cabin, *Tr\_air*, were lower than 0.6 ◦C and 3.2%, respectively. Predictions of *Tr\_air* were more accurate because the boundary conditions were more suitable to predict.
