[EnergyPlus_Support] Re: Ground temperature of Singapore

Update: *EnergyPlus developer please respond*

OK I now know how to calculate soil temperature as a function of depth from Hillel, 1982.

Essentially his equation says that at 0 m depth, monthly average soil temperature is the monthly average air temperature plus 1°C. This is basically a sine wave. With increasing depth, the soil temperature gets closer to the annual mean air temperature plus 1°C. 

NEW QUESTION: Is this what 'Site:GroundTemperature:BuildingSurface' wants? i.e. 0 m depth soil temperature. Or some other depth? Or some other 'ground temperature' altogether?
