A Field Survey on Traditional Residential Earth Buildings in Southern Hunan and Analysis of the Indoor Thermal Measurement

Typical residential earth buildings in Southern Hunan area are of civil engineering structure, namely, adobe walls, wooden doors and windows, wooden roof truss covered by blue tiles. In this paper, the author made a field mapping and energy consumption survey on a typical residential building in Southern Hunan area, and conducted an indoor test on heat and humidity index in summer and winter. The results are shown as follows: The typical residential buildings in Southern Hunan area are of good thermal insulating properties; and the environmental friendly local materials are easily obtained for construction. In the end of this paper, the author proposes a solution to overcome the defect of high relative humidity index through the enhancement of air tightness and reasonable ventilation.
