The 2 styles differed from the divergence of results for the summer-time validation period of time, though the median values remained in exactly the same range. Over the summertime time, the two models overestimated temperatures, without having advancement from your calibrated model.
The rounding of your values from the calculated temperatures influenced the uncertainty Assessment, as the actual measured values remained unfamiliar. Furthermore, the design calculates the place temperatures although assuming which the air from the space is very well mixed.
