Re: [EnergyPlus_Support] Materials U-Value Calculations in E+
That sounds like a question for the DesignBuilder
forum.
EnergyPlus also (if I remember correctly) calculates the film
coefficients for summer or winter (or maybe both).
Certainly should be covered in the Output Details document.

I know about this, but I wonder how the materials indicating in the
DesignBuilder, EnergyPlus present the same U-values.
For example, if i want to insert a U-Value 2.69, how i need to configure
this in designbuilder for the same values in energyplus report?

You should note that EnergyPlus report two values for U, one with and on
without film coefficients. These film coefficients are usually regulated
by local standards and it is possible that EP and DB have not the same
values.

- Hi everyone,
- I need some help to understand how is the calculation of u-value
material in energy plus.
- Someone has a spreadsheet that calculates according to the material
specifications?
- I ask this because I use the design builder to enter the building
elements, and saw that the U-value is not the same in EnergyPlus
report.
- I don't know how energyplus calculate this.
- Thanks for all.
