The paper examines innovative and promising trends in in the design of high-rise buildings that challenge traditional typologies and are adapted for specific climatic conditions. The purpose of the study is to investigate modern methods of designing building envelopes for bioclimatic skyscrapers taking into account heat impact of climate on the thermal balance of buildings. The research methodology is based on a systematic analysis of advanced world experience in constructing innovative buildings, "conquering" climate. The paper provides the basic principles of bioclimatic architecture. The issues of buildings’ forms and modes are considered. The authors analyze the efficiency of using double facades in different climatic conditions with account of their interaction with other technological, constructive and planning elements, such as "solar chimney", passive and active solar control systems, landscaping, intelligence control systems of temperature and humidity conditions in premises and buildings, etc. The paper highlights that unique objects of bioclimatic skyscrapers are moving now into new typologies of buildings and help form dense, comfortable and convenient urban environment using natural resources effectively. The research shows how prospects and relevance of a systemic approach to introducing the related and interdependent projects for energy saving activities at all levels, starting from town-planning and architectural models, and ending with engineering and constructive solutions.

The current questions of prospects of modern cities development are viewed in the light of steady growth of population and urbanization connected with enhancement of cities role in social development. The problem of urban densification and the prospectivity of large cities vertical growth are considered. China practice is analyzed because this state is acknowledged global leader in the matter of high-rise building and its achievements can be useful for the Russian Federation. The article concerns activities of the Council on Tall Buildings and Urban Habitat (CTBUH) researching high-rise building. Modern approaches to highrise buildings typology are examined, their main point is defined as mini-city in city.

The paper considers the objective problems of the development of modern cities related to the negative trend of their territorial expansion. The necessity of searching for modern methods of developing a multifunctional, compact and comfortable urban environment is pointed out. It is noted that the inclusion of mixed-use tall buildings in the urban structure allows using land resources efficiently and improves the quality characteristics of the living environment significantly. The authors analyze the global experience in designing mixed-use tall buildings with identifying the peculiarities of their functional structure.
