Nakkazhinova A.A. (16-MSS-1.5). Golsev A.G. (EKSTU) RECOMENDATIONS ON PERFOMING FACADE FACING WORKS IN LOW - RISE BUILDINGS BUILT USING ADDITIVE TECHNOLOGY. Modern facade system is a composite structure consisting of different materials, depending on the selected architectural solution. The main facade systems can be divided into several types of "wet facade system", ventilated facades, facades of sandwich panels, translucent facades. Translucent facades used in the construction of modern buildings are by far the most relevant. Glass refers to materials, the use of which for facades allowed to give them a distinct look that matches the idea of the perfect modern building. As the experience of practical application of translucent facades, in particular on the reconstruction of the Technopark "Altai", this is the place to be in our region (Figure.1 and Figure.2). Figure.1. The construction of the glass façade and domes in Technopark "Altay" But for now the design stage is decisive for energy efficiency and glass have a low resistance to heat transfer. In the course of scientific studies have shown that the bulk of heat loss occurs by radiation (radiative) component of the thermal energy directed to the external environment. Therefore, in order to reduce the heat leakage, it is necessary to provide reflection of infrared radiation inside the building. Figure.2.Technopark "Altai" - new facade Technological innovation is the creation of multifunctional selective glass with a "soft" sputter coating. Passing most of the visible solar spectrum, they cut off long-wave thermal radiation. This avoids overheating of the premises and, as a consequence, reduced costs for ventilation and air-conditioning. At the same time it is a complete energy saving product. Windows with such glasses have high thermal performance, in particular heat-transfer resistance of 0.62 sq. m/W. The idea of a multifunctional glass is that in one product to combine two features: thermal insulation and heatproof. The technology is the alternation of functional and protective layers. The upper and lower layers of oxides and nitrides that affect the reflectivity, transmittance and color. The main functional layer of various metals (silver, chrome) provides a reflection of short-wave and long-wave thermal radiation. To protect the main functional layers from mechanical and chemical damage, as well as reflection and absorption of short-wave heat radiation between these layers is a protective coating. A protective layer of silicon nitride allows to expose multifunctional glass tempering according to the conventional technology: heating to 600C and rapid cooling. However, at the stage of developing design and estimate documentation or in design organizations, construction companies, these issues are not always worked out. So when designing the glass facade of the Technopark "Altai" has not been worked out the issues of trial design such technologies for energy efficiency, there was no professional heat loss calculations, designing heat shields and equipment, respectively, that further leads to unjustified costs for the additional installation of teplovikov and other equipment. At the stage of implementation of construction works it became clear that not developed the connections of glazing, waterproofing, as well as components of the wastewater master plan of snow management. Deficiencies in the design has led to a significant loss of time and a sharp decline in the quality of work performed, respectively, increased heat loss, resulting in additional unnecessary costs. Thus, the use of translucent facades, especially with selective multifunctional glasses in our region is very problematic. Need for careful engineering preparation of specialists of designers, constructors and architects. It is desirable to have a relationship with the real suppliers that operate on the principle of "price – quality". References 1.
