The soil samples collected respectively from Xi'an in Shanxi, Turpan in Xinjiang and Lhasa in Tibet were processed into three types of adobe specimens according to the same density level to study the effects of different moisture content on the thermal performance of raw soil materials and energy consumption of raw soil building. Then the thermal conductivities of these samples were tested from the vast dry to wet saturated state, and the influence regulation of changes of raw soil thermal conductivity on heating energy consumption in different moisture rate conditions was studied with methods of dynamic energy simulation and sensitivity analysis. The results showed that:There is a linear correlation between moisture content and raw soil thermal conductivity; The regional differences of influence to moisture content on raw soil building heating energy consumption were very significant; In the high humidity conditions, heating energy consumption of Xinjiang adobe building had a minimum amplitude with the addition of moisture content.
