In the article, the author describes the technological peculiarities of erection of frame buildings at negative temperatures. The author also demonstrates structural and technological peculiarities of prefabricated frame elements. The author also speaks about the technology of prefabricated production of stacked columns, pre-stressed girders, beams and hollow core slabs.
It is proven that the frame system is applicable for the construction of industrial, residential and office buildings that may have different numbers of storeys and that are flexible in terms of design concepts. Besides, the author describes the technological peculiarities of the assembly of structural elements, their temporary and permanent fixing.
The author also provides basic requirements applicable to the technology of grouting of column-to-girder joints and hollow slabs designated for a cased frame. The article also contains an analytical solution of the heat conductivity equation that describes the period of heating of connected elements. The solution makes it possible to use numerical methods to identify the depth of heating of girders and columns, depending on the ambient temperature and the duration of exposure to the heat.
The author has also analyzed the technology of grouting of precast structure joints at negative temperatures in the event of pre-heating of structural elements to be connected and the heating of the concrete mix with heating wires. The author has identified the range of rational heating modes for structural joints on the basis of the parameters of negative temperatures.

In the article the short historical review on the design of sanitary rooms and their configurations is given. The main errors of the recent years, which led to the decrease in accommodation convenience because of the wrong approach from both the architect and engineers, are given. It is possible to use a small useful area for sanitary facilities, but it is connected with the lack of possibility of connecting washing and dishwashers. The author considers the options of engineering equipment placement in sanitary rooms taking into account the convenience of use, safety, and also resource-saving aspect. Various solutions on the organization of heating and ventilation are provided. The possible technical solutions allowing solving a flooding problem of the first floors in elite housing estates in case of accident are offered with the help of full waterproofing of sanitary rooms, and also the whole area of the apartment. The main attention was focused on the improvements of sanitary rooms for one-room and two-room apartments, which are the most demanded in the modern market of real estate. Layout solutions of the reduced bathrooms on the placement of the necessary equipment with choice justification are provided. The attention is paid to the layout solution for modern kitchens on order to increase their comfort by the use of special two-section sinks, and also a grinder of food waste in order to allow to lower the load of the systems of rubbish disposal of a building, by dumping the crushed garbage in an internal sewer network. Various options of evolutionary development of sanitary rooms for increasing the comfort degree are given. First of all, the development should happen in the direction of not only sanitation and hygiene, but also of the maintenance of the physical health of the people living in the building. It can be carried out by increase in a useful area of sanitary rooms, installation of exercise machines, medical bathtubs and a Jacuzzi, which allows receiving good relaxation after a difficult day. Also one more direction will be the organization in occupations of an aquacycling, so-called water trainings in a special bathtub by means of exercise machines for strengthening of health of the population.

The objective of the research performed by the authors is to identify the role of energy efficient engineering systems and to assure the energy saving and comfortable indoor environment. The choice of supply-exhaust ventilation systems versus cold supply systems with heat recovery are also considered in the article.The authors argue that the most comfortable and efficient heating system is the one composed of heating panels incorporated into enclosing structures of buildings to ensure the radiant temperature on the premises. This system used as a supplementary heating system backing the hot water heating system that has heating panels integrated into enclosing structures makes it possible to limit the solar heat supply into the premises in summer to improve the indoor environment, whereas any heat perceived by the water from the solar radiation may be expediently used for hot water supply purposes. In the summertime, the proposed system may reduce the solar heat supply, if chilled water is supplied into the system by chillers.Besides, the authors remind the audience that the choice of heating, ventilation and cooling systems needs to be made at the initial design stage depending on the purpose of the building and other factors affecting the rational choice of engineering systems. In some cases, zone heating systems or hot air systems are expedient.

The implementation of energy saving actions in the course of renovation of residential houses is considered by the author in the article. The need to change the mode of operation of heat supply systems and the employment of steam-gas co-generation power plants as a source of heat is demonstrated.
Therefore, the problem of power saving in the course of renovation of residential houses comprises several constituents, and its resolution involves the implementation of a number of interrelated organizational and process-related actions. This is the only way to avoid conflicts and to reduce power consumption and losses at each stage of power generation and transmission absent of any deterioration of the internal microclimate in renovated premises. The implementation of the aforementioned actions will make it possible to convert to the automatic energy consumption reduction mode through the implementation of engineering solutions and without any immediate involvement of legal entities. This methodology may arouse the interest of both producers and consumers of thermal and electric energy.

Subject: systems of passive solar heating, which can, without the use of engineering equipment, capture and accumulate the solar heat used for heating buildings. Research objectives: study of the possibility to reach the passive house standard (buildings with near zero energy consumption for heating) in climatic conditions of Russia using the systems of passive solar heating in combination with other solutions for reduction of energy costs of building developed in the past. Materials and methods: search and analysis of literature, containing descriptions of various passive solar heating systems, examples of their use in different climatic conditions and the resulting effect obtained from their use; analysis of thermophysical processes occurring in these systems. Results: we revealed the potential of using the solar heating systems in the climatic conditions of parts of the territories of the Russian Federation, identified the possibility of cheaper construction by the passive house standard with the use of these systems. Conclusions: more detailed analysis of thermophysical and other processes that take place in passive solar heating systems is required for creation of their computational models, which will allow us to more accurately predict their effectiveness and seek the most cost-effective design solutions, and include them in the list of means for achieving the passive house standard.
