Psychological Motivation Analysis of Farmers' Collective Energy-saving Behavior and Influence of Intervention Effect

Abstract

The poor thermal performance of rural buildings in northern China and the serious pollution caused by loose coal combustion are practical problems that need to be solved urgently. In order to solve the two problems, this paper analyzed the current situation of the envelope structure of rural houses in the north of our country and the commonly used heating forms of farmers. It was found that the envelope structure of most rural houses did not take heat preservation measures and needed to be transformed to save energy. The commonly used heating systems for farmers are coal furnaces, hanging kang, earth heating, etc., and the wealthier rural areas use biogas or straw gasification for central heating, but there are still various problems to be improved in these systems. In order to improve the thermal performance of the farmers' building structure, the thermal performance measurement and energy-saving transformation of the enclosure structure of a typical farmer in Xiaoyi, Shanxi Province were carried out. Before the energy-saving transformation, Energy Plus software simulation analysis shows that the typical farmer can save 60% of the heating energy consumption after the energy-saving transformation. Before and after the energy-saving transformation, the actual measurement results show that the heat transfer coefficient of the wall, window and roof decreased by 72.7%, 61.59% and 64.99% respectively from 2.3 times, 1.43 times and 2.11 times the national requirement limit. The performance of the envelope structure after the energy-saving transformation can meet the national requirements. The actual statistics show that the biomass fuel consumption per unit temperature difference before and after the transformation is saved by 66.74%, which indicates that the energy-saving transformation has achieved good results, and shows the accuracy of the Energy Plus model. The psychological intervention of energy-saving transformation proposed in this study helps to improve people's awareness of energy-saving, reduces anxiety and fear, and has a very good effect on the psychological intervention effect.
