Abstract
 

The construction of rural houses in severe cold regions is mainly the personal way with self-raised and self-built, lacking of the professional design and guidance. Survey shows that villagers pay more attention to the construction cost, resulting in the energy conservation measures rarely applied in the new houses or existing buildings reform because of the additional investment and the building heating consumption increased significantly. This paper aims to investigate the economic benefits of Woniuhe new rural house, which applied several energy saving measures in terms of building shape, functional layout and envelop structure. On the basis of calculating the energy saving house’s additional investment and saving cost for heating, the method of dynamic economic analysis was adopted to calculate the dynamic payback period under different growth rate of energy price and energy saving rate in life cycle, It turn out that energy-saving house has well economic benefit in the long turn, and the additional investment can be withdrawn in about eight years. Meanwhile, the field measurement was used to verify the advantages of energy saving house in the indoor thermal environment, the results shows that in winter the energy saving house presents high temperature, in the bedroom about 4-5°C higher than traditional house, and the internal surface temperature of exterior walls and ceiling is always higher than the dew point temperature.
