Quality of human living environment is determined by combination of factors which constitute indoor space thermal, light and acoustic conditions. At the stage of building design it is essential to undertake complex analysis allowing revealing quantitative values of the governing factors and forecasting their joint influence affecting indoor microclimate formation.

The article presents research materials and analysis of factors affecting the creation of new nodes of public spaces, as starting points for the development of Kotlin Island and the city of Kronstadt. Their current state and problems, resources and opportunities are described. Currently, there is a process of rethinking the value of the coastal territories of Kronstadt, the potential of which is not realized. One of the possible ways to solve this problem is to increase the use of coastal territories by creating tourism and public-business infrastructure along the coastline. Kronstadt has a number of unique characteristics, the use of which can transfer it from degrading to developing. This is possible by creating a polycentric model in the city - new growth points, as well as rethinking the value of abandoned and coastal territories. This approach will not only increase funding, attract more people, provide a sufficient number of jobs, but also subsequently create conditions for the further development of the city as an independent unit - the center of the St. Petersburg metropolitan area.

The paper discusses the principles for organizing the architectural environment of Arctic cities using the example of Vorkuta, (Russia). The subject of the study is the architectural environment of Vorkuta and the influence on its formation of various groups of factors - climatic, psychological and environmental. Based on the study of the history of the appearance of the city and its condition today, the prospects of the region are assessed, and the main development vectors are identified. As a result of a comprehensive analysis of external factors and development prospects, the principles of organizing the architectural environment at different levels are formulated: urban planning level - the city and the quarter, architectural and planning level - the building. The principles of a possible organization of Vorkuta architectural environment are systematized, both in terms of impact levels and certain factors of influence, which are most significant for the region. The architectural environment of the city, created in the image of the cities of central Russia, was not adapted to the harsh northern climatic conditions. Studying the influence of various external factors on the urban environment will help formulating a conceptual scheme of the organization. In the future, it will prevent mistakes and contribute to the development of the city.
