This article highlights the contextual approach to the renewal of the historical urban environment as the most complete and delicate one, which allows to comprehensively analyze the historically formed urban situation and to take into account all of its nuances in order to harmoniously add the new building to it. The article shows the principles and techniques, which are used to harmoniously combine the new buildings with the historically formed urban environment.

In the paper are presented the results of diagnostics, tests of materials, numerical modelling and static analysis of the current state of the bearing steel structure of the hall after a fire and design of the actions for the repair of the damaged steel structural members.

In this paper the results of mathematical provement of economical optimal thermal resistance of a building wall are presented at condition of both heat energy and thermal renewal cost change on future. There are presented comparation of technical and economical indexes at external walls renewal at the different characteristics of enclosure constructions.
Purpose is to analyze the technical and economic factors that determine economic feasibility insulation of external walls subject to changes in the cost of heat and renewal in future.
