Menu scheme method for energy saving renovation of rural house envelopes

The energy conservation of rural houses is one of the important contents of the current rural construction. Based on the field investigation of rural houses in northern areas, this paper conducts a study on the energy saving renovation scheme of rural house envelopes, and then proposes and designs a menu type optimization method of energy saving schemes. This novel method takes into account the energy saving effect of different insulation schemes and the economic affordability of farmers. It can not only give the optimal scheme for the energy saving renovation of rural house envelopes under a given budget, that is, “recommended dishes”, but also intuitively show the initial investment and the corresponding energy saving rate according to the user’s “self-selected dishes”. The menu method has high efficiency, flexibility and universality, which gives practical value to determine the energy saving renovation scheme of Chinese rural house envelopes.
