| Lately, as speedy development of our national economy, our countries pay more attention to other aspects except economy, such as environmental protection, energy conservation, which are vast orientation, as well as some detail, such as the improvement of living condition etc. Because of the maturity of diversified legal system, serial technical rules of law and standard criterions are established. Further more, as to modern technology change with passing day; there are so many new type materials, which concerns on energy conservation of envelop construction, their efficiency of energy conservation, economical, perfoemance of environmental protection and practicability effect the extensive applications of thenselves.This paper according to construction energy conservation criterion, if want to achieve energy conservation 50% in total, then the envelop configuration of buildings whose energy conservation must to reach 30%. Base on diathermanous static state model establish a target function which variables are index of energy consumption and cost of per heat barrier, to analyze the indexes of variable conditions of the construction, then achieve the optimal resultants of envelop configuration. This paper mainly on there facets: firstly, Fix a ratio of wall and window, then optimize the envelop configuration, whose index value are optimal respective and integrated, and then change the ratio, do the optimization calculation again; secondly, fix cost. In prescriptive original invest range, to optimize the combinations, whose energy consumption is the lest one; thirdly, fix material. To choose one or several kinds materials among wall, window or roof, calculate the respective index value of combinations, which are made up of the fixed materials, therefore, to analyze and compare the index values of the combinations. The every variable in the target function of this paper is discrete, so by reading a lot of references and literatures, then collecting some materials and correlative data, which are analyzed and calculated, and ultimately put them into tables, when the target function need the data ,it can get them from the tables.The target function of this paper is not only concern on energy conservation or economical benefit, but also takes the other performances of the materials into account, therrfore, the final optimal resultant is practical.
