CONSTRUCTION OF COST BUDGET MODEL OF LOW ENERGY CONSUMPTION BUILDING PROJECT BASED ON SPACE RECONSTRUCTION THEORY

In the new situation, it is of great significance to effectively carry out construction engineering management to promote the development of construction engineering. In order to improve the quality of atmospheric environment around the construction and reduce the cost budget of low-energy construction project, the paper constructs the cost budget model of low-energy construction project based on space reconstruction theory. According to the theory of space reconstruction, the influencing factors of low energy consumption building engineering cost are obtained, and the factors are used as the input of the model to establish the cost budget model of low energy consumption building engineering, and the cost budget results are output; The wave guide method is used to establish the cost gain balance model of low energy consumption of building engineering, and the gain equalizer in the model is used to reduce the deviation of engineering cost budget; According to the result of minimum deviation of engineering cost, energy consumption function and optimization decision function are established to obtain building energy consumption capacity, so as to realize low energy consumption optimization of construction engineering. The experimental results show that the deviation between the predicted project cost value and the actual value is small, and it can be accurate to three decimal places, so the project cost budget ability is strong; After the application of the model, the pollutant concentration is reduced by about 1.02 mg.m(-3), which can effectively improve the atmospheric environment quality near the construction site.
