The thermal performance of a normal size room (4 m × 3 m × 3 m) connected to an idealized earth‐air tunnel has been analysed interms of heating degree‐hours (base 18°C) and cooling degree‐hours (base 30°C). The effects of various earth‐air tunnel parameters on the heating degree‐hours and cooling degree‐hours have been studied. The effects of various treatments of the earth surface over the tunnel have been analysed for three different climates (namely hot‐dry, hot‐humid and cold‐dry) prevalant in India. The earth‐surface treatments for hot‐dry and hot‐humid climates include shading and wetting of the earth surface, and for the cold‐dry climate, the surface treatments considered are blackening and glazing of the earth surface.
