Air Velocity in Air Cavity of Curtain Wall System at Free Ventilation
The formation of an air-heat regime under the condition of free ventilation of an air cavity in the curtain wall system (CWS) is considered. A differential equation describing the temperature distribution over the height of the cavity, as well as an approximate equation for determining the air velocity in the cavity has been obtained. The estimation of the maximum achievable air velocity in the cavity has been made. The results obtained can be used to estimate the emission of fibres from the mineral wool insulation of CWS.

Keywords: curtain wall system, air cavity, air velocity, free ventilation of cavity, intensity of solar radiation.

he History of Architecture of Orthodox Temples of the Black Sea Coast of Russia
The first orthodox temples of the Black Sea Coast of Russia in Sochi, Novorossiysk, Gelendzhik and Anapa are presented. Their architectural and artistic solutions, problems of reconstruction and restoration are considered. Special role is given to the internal contents of the temple. The focus is on the compositional structure of the temples in the system of the settlement.

Protection of Timber Structures in Places of Resting on Stone Walls and at Their Intersections
Methods of protecting wooden beams against wetting and bio-destruction in places of resting on external walls of heated buildings are described. Recommendations on the protective treatment of side faces of bearing glued timber structures of beam type having solid, including paired, cross-section in the zone of intersection of insulated external walls and vitrages are made.

Keywords: dead and open embedding of beams, waterproof bandage, antiseptic treatment, sealing, heat insulation.

Architectural Potential of Roof Space of Multistory Residential Buildings
Conditions of the architectural formation of spaces of exploited roofs, methods of their placing in the urban development are considered. Factors influencing on their architectural-planning decisions, operation and structural features have been defined. The potential of exploited roofs as an additional source of improving the comfort of human life and activities in the urban environment is revealed.

Keywords: exploited roofs, planting, methods of roof space formation, multistory residential building.

Organic Life Environment at the Extreme North
Results of the study of everyday life of a particular paternal clan who lived in the plain lands of Central Yakutia in the first half of the XX century are presented. The existing organic bases of formation of the traditional Yakut dwelling of the late historical period, as well as the necessary household outbuildings for doing the northernmost herding are investigated. The research material was obtained during numerous trips to the region, the study of archival data, measuring works and direct interviews with the residents. Conceptual designs of the Northern architecture are shown.

Keywords: organic life environment, fundamental organic base, paternal clan, traditional housing, seasonal settlements.

Coefficient of Sustainability as an Instrument of Economic-Ecological Assessment of Residential Development
Modern system of assessment of the environmental safety takes into account very limitedly the state of the environment when planning residential development of urbanised areas and completely ignores the change of ecological situation after completion of works. Till now the real instrument of such evaluation has not been created. Existing methods of assessment of the construction influence on the environment are, as a rule, prognostic and don’t take into account the reaction of the ecosystem to anthropogenic impact. More important indicator when evaluating the influence of construction is sustainability of the ecosystem at the level of a balanced state. Main stages of development of the concept of sustainability of systems are described. Knowledge of potential possibilities and characteristics of functioning the ecosystems of a specific territory are necessary for development of regional and local systems of ecological monitoring, rational land use and protection of environment. However, the mechanism of functioning of ecosystems and its reaction to changes in natural and anthropogenic factors is studied not enough, because each structural element and functional component of the whole ecosystem is studied as a separate academic discipline using special methods. This mostly refers to the ecosystems on urbanized territories. Development of an improved assessment system of the environment will make it possible to rationally assess the ecological situation on already built-up areas, conduct construction works and maintenance of new objects without harming the surrounding area. Development of modern methods of assessment of ecological safety of artificial ecosystems is one of priority directions of the modern ecology. Substantiation of the use of the coefficient of ecosystems sustainability as an instrument of this assessment is presented.

Keywords: economic ecology, ecological safety, urbanized territories, coefficient of ecosystems sustainability, sustainability index, sustainability.
