Design and calculation of energy efficient windows of high-rise building

The paper identifies the key issues concerning design and calculation of energy efficient windows of high-rise buildings that should be considered at the initial stages of a building design. The analysis of the functional and technical requirements which must be met by window structures in high-rise buildings was performed. The features of wind loads on the high-rise building windows were considered. The specificity of providing air- and water permeability of high-rise building windows under the action of high wind loads was considered. The conducted scientific research review on specific design and calculation issues of high-rise building windows was made. It is established that they are mainly aimed at finding optimal design solutions of the high-rise building windows in terms of energy efficiency. A similar situation is observed in the design of windows, when the issues of ensuring the strength and reliability of these structures are given less attention. It is established that at present, the strength calculation methods of fasteners and protective fences of windows are not developed; the excess stock is laid in the method of profile elements strength calculation, which is confirmed by the results of laboratory tests. The prospective scheme for calculating and appointing design solutions of high-rise buildings windows was presented, which provides an opportunity to ensure reliability, durability, and operational safety of high-rise building windows during all their life cycle. The paper specifies areas for further research of the matter under consideration.
