In the scope of the article the problem of heat and humidity structural damage’s adverse effect on energy efficient building maintenance is considered. The main object of the research is the calculation and analysis of thermal bridges as a considerable factor, making worse the energy efficient building qualities. First the analysis of the most widely-spread structural damages were examined, then the thermal bridges estimation on the basis of Austrian software „AnTherm“ was carried out which represents an universal software package of thermal bridges damaged structural thermodynamic behaviour’s analysis. The calculation of a 60th year building house’s structural junction of foundation plate and wall was carried out. The results enable us to draw a conclusion that the researched structural junction doesn’t create any conditions for the thermal bridges formation.

An introduced article is devoted to the problems of ecosystem approach implementation as an innovative component of building project’s management on the preconstruction stage of the building life cycle. In the scope of the research it was proceeded from an assumption that any building project is a complex system which persistent interacts with its environment. The main features of the preconstruction stage were laid down the foundation of ecosystem approach implementation. The developed algorithm enables to cover a great number of problems, following from compound urban ecosystem interactions. The introduction of ecosystem approach was divided into several stages, which could permit to hold of the balance of compound urban ecosystems. In conclusion it might be underlined that ecosystem approach implementation is to be carried out taking into account complex interactions between ecosystem’s components.
