The article studies the peculiarities of architecture of enterprises and small-scale energy facilities in the urban environment. A number of problems arising in the interaction of small-scale energy facilities with urban development and their placement in the urban space are described. The prerequisites of architectural and spatial classification of small-scale energy facilities are emphasized. Classification of types of small-scale energy facilities by functional, urban planning, volume-spatial and compositional features is proposed. The requirements to the architecture of small-scale energy objects and their integration into the architectural and spatial context at the present stage are formed. The identified requirements and types of small-scale energy objects create a methodological basis for the formation of adaptive approaches and promising directions for the harmonization of these objects in the structure of urban spaces.

The article deals with the issues of assessing the effectiveness of the construction and operation of metal corrugated pipes. The characteristic features and difficulties of the operation of corrugated metal culverts in areas of permafrost distribution are revealed. The characteristics of the main defects of culverts are systematized. The features of thermophysical calculations of metal corrugated pipes on a frozen base are analyzed in detail. Recommendations are given on the application of the most effective technical solutions in the construction of corrugated metal culverts on permafrost soils.

The article deals with the problems of communication between the customer and the development team in the process of designing information systems. Based on the identified shortcomings of existing solutions, a conclusion is made about the need to develop a new approach and means of its implementation. The paper sets the task of developing a common model for the interaction of subjects using a single platform. The article describes the concept and modular architecture of the platform for implementing the system notation for designing architectural schemes. The modules of such a platform and its general functionality are considered.

The paper issues a technique for constructing effective data insertion procedures in structure-independent databases that uses the activity approach. The essence of this technique is to present the procedure in the form of an action mechanism that allows its semantics to be opened, thereby minimizing the number of identical same meaning characteristics. The use of the technique for data insertion procedures constructing into structure-independent databases, as well as the use of a NoSQL DBMS that is homogeneous in structure to structure-independent databases made it possible to significantly improve performance. You can judge it from the computational experiment which is performed in the work.
