The solution of environmental problems of the modern city requires a systematic approach and should include measures for cleaning and protection of all environmental components of the city. As a part of the complex improvement, one of the most simple, inexpensive to implement and at the same time effective methods is to increase green areas of the city. The article deals with the spatial analysis technique of urban green spaces distribution density using modern geoinformation systems on the example of the city of Rostov-on-don. Spatial analysis is carried out in the software package ESRI ArcGIS 10.1. The result of the technique realization is the construction of an electronic map of the city's greenery distribution density, as well as the assessment of the environment quality by comparison with the electronic map of the habitat quality index for the estimated areas.

The article is devoted to the study of the location of buildings in the city of Rostov-on-Don,with considering the town-planning aspects of planning urban areas. In the process of research, a geoinformation database was created with the criteria for the location of residential buildings in various geological risk zones. As conclusions to the article, an analysis was carried out with the identification of the location of buildings in complex geological and environmental conditions within the city of Rostov-on-Don.

The paper is considered modelling the process elaboration of a pit for high-rise building in the case of dense urban area. The research is analyzed stress strain state of soil with retaning wall. The authors are developed various design solutions of the retainig wall to decrease of displacement of the nodals in soil finite element model. According the results, it has selected rational design solution of retaining wall.

The article describes the main provisions of methodology developed by the authors for evaluation the effectiveness of resource-saving solutions in the housing construction. This methodology is based on the assessment of sustainability, which is obtained by residential buildings through the implementation in practice the resource-saving technologies. In its framework, the authors propose a system of indicators characterizing the social, economic and environmental aspects of building’s sustainability and the corresponding scale ranges for their scoring. Taking into account the theory of pair comparison, the authors developed an algorithm for determining the contribution of each indicator in the overall integral sustainability of the building.

One of the most important measures to reduce the risk of natural and natural-technological disasters is the engineering-geological mapping of the city area, carried out in accordance with a group of geological factors such as topography, formulation and properties of rocks, hydrogeological conditions, geodynamic processes development, etc. On the territory of the city of Novocherkassk as well as in other areas of urban settlements in the Rostov region, the active development of devastating processes associated with the extensive spread of clayey soils with low values of high strength characteristics and high water cutting groundwater arrays, caused by both natural active processes and technogenic influence. After the research conducted, it was decided that the area of the city of Novocherkassk is divided into zones of geological risk. Thanks to the mapping of the territory, it is allowed to make the right architectural and planning decisions and exploit it with well-executed investments, with security requirements.

Abstract: preventing the formation of ice on roofs and gutters of buildings appears to be socially and economically significant goal, requiring efficient and effective decision-making. Roof and gutters heating has the potential to avert the loss of life and vehicles damage due to falling icicles. The costly package of measures of manual cleaning of roofs, which often leads to unscheduled repairs of roof , gutters and facades of buildings is thus not needed. A competent choice of the way of heating is able to provide positive social and economic benefits for the city and must be done according to the availability of specific types of energy resources ... The article justifies the applicability of water heating system that runs in both automatic and manual control. Such systems allow the use of heat supplied by CHP local boiler or gas compact heater.
