Re: [EnergyPlus_Support] Thermal capacity of walls

Hi, Jeremiah.

I would like to find an easier way to calculate it, inside the software, but I appreciate you sending me the attachment.

Regards,

Leticia Neves

ASHRAE 90.1 calls this Heat Capacity or HC.  It is calculated by as follows for each material in the construction layer 'Layer 1 Thickness X Density X Specific Heat + Layer 2 Thickness X Density X Specific Heat + Layer 3 Thickness X Density X Specific Heat' 

I have attached a workbook with the calculations included.

Leticia, 

i've checked here too and I do not find this output. 

You may need to request the outputs to calculate the thermal capacity. I believe that the software does not have this specific output.

Now i'm curious about this too.

Hi, Ivan.

I already checked and it I didn't find it. Do you know the specific name of the output?

Regards,

Leticia

Hello Leticia, 

check these itens:

- Output:Table:SummaryReports

- Output:Variable

Maybe variables have the output that you need.

Hello,

I need to calculate the thermal capacity of the walls of my model (kJ/m²K). How can I ask for this output in EnergyPlus? The table shows me only the thermal transmittance (U value).

Thank you in advance.

Regards,

Leticia Neves
