AERODYNAMICS OF THE CITY

The “input-output desideratum”, outlined in the New Athens Charter, sets new requirements for urban designers. Nowadays, using modern techniques, we can solve weighty contemporary urban problems using such system of designing, which balances quantitative and qualitative parameters of the urban matter. The text presents the part of the designing system that uses methodology of the meteorology. Proper use of this system allows to control and design parameters of the socalled urban canopy. The urban canopy covers the area of reduced energy consumption and increased comfort of using the public space between the buildings constituting urban tissue. Urban canopy is characterized by multiplier effects, obtained - among others - thanks to the use of aerodynamics in urban design. Shaping buildings, supported by empirical method (with use of models), allows to implement the so-called filters and regulators postulated in the Charter: the elements that maintain the city's structure in balance.
