The average percentage of high-rise residential buildings in Russia is approximately 5% from the general volume of house construction. However, the demand for this type of buildings begins to increase. This factor relates to establishment of coherent multifunctional living environment with complex infrastructure. All of this facts cause the problem of high-rise building construction, including the design of engineering systems. Building air mode is influenced by external pressures applied to the centers of air-permeable openings, including wind pressure. Wind speed increases in the height of the building, but this change is often neglected in multi-storey houses, of course it is necessary to take this phenomenon into account designing high-rise buildings. The article presents various methods of accounting wind speed change in height, which were calculated for different cities in Russia. According to the of wind speed results obtained, the specific rate of infiltration air has been calculated, which significantly exceed the values in the case of a constant speed.

Consideration of Wind Speed Changes in the Design of Ventilation Systems for High-rise Buildings
