Re: [EnergyPlus_Support] equivalent wall properties calculation





You can either do a composite wall which has the thermal properties proportional to the different wall secions. Or have separate wall sections with different thermal properties.

Dear all

I encountered one problem and I hope to get some ideas from all of you if convenient.

For complex and large building, can we do combination of different wall types?
The scenario is like this: for a thermal zone, the south wall is made up by several sections; and the sections are using not one kind of opaque construction elements.

Can we do the combination and use one equivalent construction type?
like use area weighted U-value, specific heat value and density value?

Thanks and Best Regards
