The article shows that when solving the problem of optimization of the project of construction works it is necessary to take into account the factors of energy and resource saving. An assessment of the importance of the criteria for energy and resource saving measures at the design stage of the construction organization project is given. The use of matrices of paired comparisons allows you to perform the optimal search for energy-saving measures, which will lead to the selection of effective organizational and technological solutions at the stage of development of the project of works.

The structure and maintenance of housing analyzed. Put more abstract and an extensive understanding of the concept of modernization as the complex development of residential real estate. Classification of modernization of housing types: endogenous, endogenously-exogenous, and exogenous to create a multi-objective optimization model of the process with the required level of adequacy. Theoretical substantiation of complex approach.
