Full Description
This paper presents data from one-, two-, and three-dimensional temperature fields in the soil surrounding an earth-sheltered house. The construction and installation of the temperature sensors is discussed, and the sources of error are evaluated. The precision of the measured temperatures is shown to be +/-0.12C. Twenty-four hours of data from the one-dimensional temperature field in the roof soil are presented in the form of tautochrones. Data from cross-sections of the two-and three-dimensional temperature fields are presented as isotherms taken at approximately one-month intervals during winter and spring. The data show that extended roof insulation impedes heat flow to the ground surface in winter but allows heat to flow to the cool soil depths in summer.
