This paper analyzes the design structure of the planted roof and the construction process of each construction level to find the steps that can be integrated with the self-insulated exterior wall panels. Based on the building information model, the development program of assembled composite self-insulated exterior wall panel is developed to complete the information coding of related structural components. Combine the dual code network planning (DCNP) and particle swarm algorithm to construct the construction progress-cost target optimization mathematical model and determine the optimal integrated construction scheme. The results show that the total heat transfer heat flow of the planted roof is 136.51W/m2, which is at a good level and is suitable for integrated construction with self-insulated exterior wall panels. The heat transfer coefficients of 4 combinations are 0.545, 0.376, 0.452, 0.317, which are in line with the actuality through the exterior wall panel model designed by the development program. In the wall panel width area of 0-0.25m, the degree of temperature influence of each type of components in order of magnitude is as follows: tie member>connector>steel reinforcing mesh, and it is necessary to take into account the amount of purchase of components and the time for purchasing, and to reduce the cost of construction losses.
