Same template with same construction but different external conduction gain

[ecoville]

I have tried to make a comparison of the different design strategies and made a simple template and used it for the analysis.

The results was a bit different from my expectation, so I have tried to make a two model with the exactly same geometry.

I have copied one template from another file I have made earlier and did apache simulation.

When I have a look at the result in Vistapro, the weather data, internal gains and hvac profile is the same, but the external conduction gain is totally different.

I have compared input data several times and the input parameters are same, so I am not sure what might make the difference.

Could anyone who have a similar experience can give a tip for it?

I have experienced the same issue. Does anyone know how to deal with this? Or what is the cause?
