Web1 Jan 2015 · The ground temperature profile is characterized by three different zones: 1 – surface zone (down to 1 m below the ground surface), 2 – shallow zone (from 1 m to 8 m), and 3 – deep zone in which the temperature remains almost constant throughout the year (below about 8 m). This latter temperature is called “undisturbed ground temperature”. WebEnergyPlus provides three ways to calculate these undisturbed ground temperatures: 1-Finite difference, the default option. 2-Kusuda-Achenbach, 3-Xing.
