Hi all, Energy plus whether data has soil temperatures in different depth (using Climate Consultant application) does anyone know if EPW data has the soil type for any location?

Thanks, MOF

Are you referring to the Climate Consultant plot of soil temperatures in the screen shot below?

These are "undisturbed" ground temperatures at different depths ie. as if the measurement was from an open field without any structures. As such, they should not be used as ground temperatures to interact with a building model. You can use a pre-processor tool like Kiva to generate proper ground temperature profiles.

The EPW file does not contain information for soil conductivity, density, etc. I don't know of a great resource to find these properties for any location. There is a nifty map-based interface for seeing survey results for soil properties in California here: http://casoilresource.lawr.ucdavis.ed...

Thanks Aaroz Boranian, the ground temperature at different depths depends on soil type, properties, and the geographical location so the EPW file must mention the soil type at least.

Thanks agane for Kiva tool and the other information.

Ground temp in EPW are usually built from external ai termperature, and the file reports a note like that about the soil assumptions:

"COMMENTS 2, -- Ground temps produced with a standard soil diffusivity of 2.3225760E-03 {m**2/day}"
