Hey,
how is a proper way to model the ground(temperature) in E+(i use Version 8.1)? Is there maybe a easy way (where the ground temperature depends just on the outside temperature)?
Thank you very much!
Regarding my question i read this: Object: Site:GroundTemperature:BuildingSurface "Otherwise, take the indoor air temperature and subtract 2C as a reasonable starting value to use for most commercial applications in the U.S."
So should I simulate (in my example a 1 zone house) without HVAC (the house is located in europa/germany) - take the averrage monthly room temperature and substract 2C - and this are the values for Site:GroundTemperature:BuildingSurface?
And if there is a HVAC system - same approach (modeling without HVAC, set ground temperature)?
Thank you very much.
This extra information should be added to your original question, not here as an answer. The short answer though is no, you can't do what you propose for a house. The edge effects are too large so the ground under the building won't be in the kind of equilibrium found under a large commercial building.
