If the building is being scaled by some magnitude, then all dimensions need to be scaled equally. Otherwise, as has been mentioned in the previous emails, the ratio of envelope surface area to floor plan area will change.

A 10x10x10 building, (heat/cool load-wise), will scale better to a 100x100x100 then it would to a 100x100x10, because the ratio of floor space to envelope area is maintained. Although only the top floor will have roof load. And a skylight will only effect the top floor of the larger scale building.

Can you change from a skylight to a window with daylighting? This would scale better.

Hi Stefano,

John's right on point (especially the elephant part). The results likely
represent some sort of curve, and are probably multivariate. My suggestion
would be to model large, medium and small scenarios and do hourly reports of
the loads to see what is happening at different outside temperatures.
