Correct , the enclosure will rise to 23 C and then maintain that delta T as the room temperature slowly changes. The spreadsheet could help design an enclosure with a servoed heater. The insulation provides the minimum delta T and the heater the rest of the delta T and servos to the set point. The spreadsheet could also be used to decide how big of a heater one would need.
So does this mean that the enclosure will rise 23C above whatever the exterior temperature is? And then just level off and fluctuate as the exterior temperature changes?

A more energy efficient way to design a temperature controlled enclosure would be to use the spreadsheet to design insulation for the maximum delta T you would ever want. Then servo fan speed to use outside air to cool the inside of the enclosure to the set point temperature. A U-shaped pipe can act as a thermal block when the fan is off.
