Intelligent design of rural residential environment guided by blockchain under the concept of green low carbon

Rural residential construction is faced with the contradiction between improving living environment and reducing building carbon emissions. In order to avoid the environmental pollution caused by the high-carbon development of rural residential buildings, blockchain technology as a green and low-carbon-oriented rural residential construction technology is introduced. Based on infrastructure, technology, function, application and goal, the feasibility of applying blockchain technology is analyzed to the design of rural residential buildings and the conception of application technology framework is put forward. Five typical sample farmhouses located in different areas are selected, and the carbon emission calculation model is used to calculate the carbon dioxide emissions of typical farmhouses in the whole life cycle. The carbon emission characteristics of farmhouses with different building materials, energy structures and living habits are analysed, and the carbon emission laws of farmhouses in the whole life cycle are analysed. The results show that: (1) Rural residential projects are mostly located in economically underdeveloped areas, which often lack digital infrastructure, human resources, and economic interests, which are not conducive to the popularisation and application of blockchain technology. (2) The carbon emissions of rural residences account for the highest proportion in the whole life cycle of rural residences (59.62%-95.69%). (3) Green and low-carbon building technology should not only reduce the environmental problems caused by greenhouse gas emissions, but also meet the daily needs of farmers and improve the comfort of the indoor environment. The purpose of this study is to inject the concept of green low carbon into the intelligent design of rural residential environment and build an intelligent system of green livable rural house construction technology method and construction technology system by combining blockchain technology, which can improve farmers' living quality and living environment while reducing carbon emissions.
