Abstract.

In the conditions of reduction of the natural energy resources and relevancy of the problem of energy conservation and increasing of energy efficiency of buildings for modern architecture and construction, there emerged the need for examination and development of the technical-economic conditions for increasing the efficiency of energy conservation systems, including the hinged ventilated facades. Ventilated facades represent a modern technology for protection of buildings from the impact of atmospheric effect, as well as giving a modern look to the obsolete objects. The subject of this article is the technical-economic peculiarities determining the energy efficiency and energy conservation potential of the system of hinged ventilated facades. The research methodology is based on the theoretical approach, with application of the methods of analysis, comparison, generalization and synthesis of scientific publication, as well as the experience in construction and reconstruction of buildings using the systems of hinged ventilated facades. The author was able to determine the cause of low efficiency of such systems – the unaccounted heat-conductive elements in the thermophysical calculation. Fire safety of the hinged ventilated facades is also being explored. The scientific novelty consists in the acquired conclusions that the plan of reconstruction of buildings using the hinged ventilated facades is associated with a number of issues (formation of the low-temperatures zones at the attachment points of heat-conductive elements; presence of hazardous materials and elements; low durability and minor economic effect), which can be resolved by using the advanced materials for anchoring systems alongside optimization of thermal and humidity regime with regards to each individual case. The conclusion is made that the problems emerging in operation of such system lead to decrease of thermophysical properties of the façade and require further research.

Keywords: thermal properties, thermophysical calculation, building renovation, building envelope, hinged ventilated facade, energy saving, energy efficiency, economic efficiency, heat-conducting elements, low temperature zone
