Thickness of internal mass material

Yes, I would think that too, but in search of the answer I performed some simulations on a very basic model. A space of 3m x 3m x 3m, no insulation, only subjected to varying outside boundary conditions.

Out of these simulations I calculated the average diurnal temperature range and how increasing the amount of internal mass decreases the average diurnal temperature range within the test cell. I did these simulations using two different methods for entering the internal mass.

The first method used the 'ZoneCapacitanceMultiplier:ResearchSpecial' object in which I increased the 'temperature capacity multiplier' in according with the amount of internal mass. The second method used the 'InternalMass' object in which I performed simulations using the full thickness and half of the thickness.

When analysing these results I found that the results when using the full thickness approximates the results of the capacitance multiplier method better than when using only half of the thickness.
