Heating and cooling load calculations based on material thermal properties

[Anonymous]

I am trying to understand the heating and cooling load calculation using building elements (roof, walls etc.) thermal properties like U value, R value etc.

For this

• I built simple model of four walls, roof and floor.

 

• Thermal properties of building elements

• 

• My energy settings are as below. Note Detailed Elements is checked.

• 

• No override is selected in Schematic Types

• Heating cooling load window is as below

• Now whether I Check Detail Elements box in Advance Energy setting or I uncheck this box, I get the same results. This means calculation is always based on "Conceptual Types" and selecting "Detailed Elements" check box is not making any difference.

• Conceptual Types parameters are as below which are different from thermal properties of building elements in the model.

• My question is that what I am doing wrong that I am not getting heating and cooling load calculations based on material thermal properties specified for building elements?

 Thanks

I would suggest go through some tutorials before using Heating and cooling load calculations..
