ENERGY-EFFICIENCY OF MODERN FACADE SOLAR SHADING

Abstract

The article presents the analysis of the basic principles of work of traditional and innovative solar protecting devices which besides their primary function contribute to reducing energy consumption. The examples of modern worldwide experience of use of solar protective elements for building’s façades are given. In the first part of this article, it was looked at the modern architectural structures described in literature. The second part is dedicated to a historical research about traditional solar protective elements known to mankind from the old times of its existence. In conclusion the possible methods of simultaneous minimization of heat losses and expenses are specified. Variants of further of scientific and practical research and projects in this field are presented. The danger of excessive ultraviolet radiation towards people is already considered by the architects while implementing all the necessary means of protection in the project and is reflected in solar protected façades design. These shadowing devices directly influence external building look and are an important part of façade design. Apart from that, more than one third of world energy consumption comes from the building sector. Since modern architecture has a huge area of glazing a decent amount of sun radiation goes through the windows of tall buildings. This solar energy might be used for energy generating and consumption in the buildings. One of the most crucial problems of historical cities is the possible adaptation of architectural monuments to new realities, conditioning, laying of engineering networks or alternative energetic resources usage. Any intervention to historical buildings is to be made after a careful examination. New technical developments might either be damaging or beneficial. Learning about potential symbiosis creates a huge capability for engineering or architectural scientific research. The future of historical cities stands behind a so-called cyberantiquity. The issue of energy efficiency in architecture regardless its unequal distribution is worldwide. The natural resources and rational nature management problem undoubtedly found a response in architectural solutions and requires continuous technological development of building materials, structures, and their use in practice. The mentioned means and methods of protection against direct solar radiation are quite possible to implement in our country and especially in our city, Odessa. So, what can be done today? It is quite possible to integrate photovoltaic panels even in historical buildings, for example, together with façade marquises. A project like this requires detailed calculation, but it can become a promising direction in the renovation and restoration of urban heritage. Combining modern innovations with traditional sun protection products proven over the years can be especially effective. The main task of modern architecture in this direction is the search and development of techniques and methods of façade protection of buildings and apartments from the harmful effects of ultraviolet light and their further application in real life.
