Research On The Design Patterns Of The Low Energy Consumption Vernacular Dwelling In Guanzhong Rural Region

Geography of Guanzhong area is received on the West drought little rain in the northwest desert, East moist fertile North China Plain; climate in cold climate zones and in summer hot and winter cold climate area at the junction, the geography and climate conditions, is very unique. This unique climate conditions have a profound influence on the energy consumption of the local rural buildings. Through survey, the energy consumption of local agricultural buildings is gradually increasing, and the shortage of the thermal performance of the existing agricultural house is caused by the waste of energy and the bad indoor thermal environment.Therefore, it is urgent to study the design pattern of local agricultural house, in order to get the new pattern of low energy consumption design for the rural house in Guanzhong region, so as to improve the indoor thermal environment and save energy..Combined with typical case of Guanzhong rural house, in the full of indoor thermal environment on the basis of a survey of, residential building indoor thermal environment, combined with the actual situation, put forward suitable using low energy consumption farm house design model and program in Guanzhong area of Guanzhong area were analyzed, finally, the use of computer simulation technology, conducted a comprehensive analysis on the various options.(1)Through the research on the thermal environment found naturally in Guanzhong area of existing farm house, in the winter outdoor temperature is-1.9degrees, indoor temperature only 0.7 degrees, summer outdoor temperature for 30.1 degrees, indoor temperature up 28.7 degrees, in winter heating and summer cooling, indoor thermal comfort degree is clearly not up to the thermal comfort demand for local residents.Therefore, it is necessary to study the design patterns of local agricultural house..(2)Combining the climatic conditions of Guanzhong rural areas, from the local agricultural Housing survey results, with the low energy consumption design method as the guide, put forward three design patterns of rural housing in Guanzhong area. Namely, the "land space mode", "the function space optimization mode", "the technological means to upgrade the pattern" ". And the three modes are described in detail..(3)From the external environment, design concept, functional zoning, low energy consumption design, building materials choice, project energy consumption evaluation aspects of design low energy consumption of rural housing scheme, through software energy of each scheme comprehensive evaluation, confirmed the energy consumption of each scheme are to achieve energy-saving requirements, building annual energy consumption for heating in 5.51~7.95kgce/(m2·a)...
