Construction environment and energy application engineering is a major with strong engineering applicability which mainly trains students to be able to engage in industrial and civil construction environment control and energy supply. According to the requirements of engineering certification, each factor of the graduation requirements control index points of construction environment should be calculated according to the training objectives and curriculum system by weight coefficient. At present, due to the short time of engineering certification in China, professional teachers still lack the knowledge, understanding and grasp of the calculation method of relevant weight coefficient, which is not conducive to the teaching under the goal of professional engineering certification and does not meet the professional development requirements of engineering certification. On the basis of engineering certification standard, this paper analyzes the relationship between graduation requirement index points and supporting courses of construction environment. By using AHP, the judgment matrix of index points and supporting courses is established and the weight coefficients of each index point factor are calculated and analyzed, and the weight coefficients of different index points of graduation requirement are obtained. At the same time, the weight coefficient obtained by AHP is compared with that obtained by credit method, and the advantages and disadvantages of each calculation method are pointed out, in order to promote the engineering certification of construction environment specialty.
