### Effect of Six Specific Parameters Included in the Validated Model
Consequently, the energy influence was only 1.0% and was counteracting. Nevertheless, the simulations on the model with no extraction of heat with exhausted air through the mechanical ventilation system's air outlets due to unpredicted air-temperature differences resulted in a moderate 3.5% higher total energy use. The simulations also revealed that this continuous operation affects the average air temperatures to a negligible extent (Figure 3). The monitoring revealed some additional details. A thorough overview of the temperature curves and the system's performance showed that there was a deviation in the cooling system in the summer. During the hottest days in August, there was a slight deficit of cooling energy in the mechanical system, which caused the entire cooling system to operate with reduced power for 5 days.

Table 1: Specific parameters in the analysis of the validated model and their influence on the simulation results for energy use at annual level. for cooling therefore decreased by 2.6%. Nevertheless, this was the effect detected at the seasonal level. In annual terms, the malfunctioning due to insufficient energy supply for cooling caused an insignificantly low result of 1.4%. Regarding the average indoor air temperature, the simulations showed an influence only during the cooling season, which, however, was also very small for this case: the average indoor air temperature deviated by less than a tenth of a degree from the validated one (Figure 3). The next feature of our analysis of the measured results was the opening and closing of the windows by occupants, especially during the heating and cooling seasons. Therefore, the validated model also included this data.
