**Abstract**. The legislative prerequisites for rapid introduction and further development of information modeling technology of construction objects in Russia are considered. It is stated that the information modeling softwares do not have the necessary set of functions for calculating and designing of building elements, according to Russian standards including. Possibilities of development of functions of the program of information modeling of buildings "Autodesk Revit" are analyzed. The estimation of the studied methods is made, the method of software development based on the development of a set of software modules (plug-ins) is selected. The problem of calculation of air exchange in rooms is described. The algorithms of analysis and transmission of information, as well as two plug-ins for determination of adjacent rooms and for calculation of air exchange are developed. An automated technology for solving the problem by the means of Revit is proposed. The creative role of the designer and the inability to fully automate the task solution at the present stage are noted. The results of automated calculation of air exchange in the three-storey cottage are presented and verified. The estimation of the proposed technology of the automated solution of the problem is given. The directions of further research to improve the efficiency of designers with the help of BIM technologies are listed.

**Key words**: building information modeling, BIM, software and information support of design, indoor air exchange, programming, plug-in. - REFERENCES
