urban landscapes form the main parts of the city. one of these spaces is urban streets, in whichsocial interactions and urban vitality reach its maximum quality and quantity. one of the principles and properties ofurban landscape design is its intelligibility. a viewer who takes a look at an intelligible city and knows it can attract newemotional manifestations of city without damaging its orig...

The experiment uses wind-tunnel modelling method to investigate an intermittent ventilation of pollutants within an urban intersection. The model is designed after a typical inner-city area occurring frequently in European countries. It consists of apartment houses with roofs arranged to the several blocks. Blocks form regular patterns divided by intersections with height to width ratio equal t...

Abstract Pollutant dispersion in urban street canyons has been widely investigated by large-eddy simulation (LES). Many LES studies focused on generic under a wind direction perpendicular to the axis. Accurate simulations require sufficiently large domain size minimize effects of artificial boundary conditions at faces results. As opposed RANS simulations, there is lack guidelines for an approp...

Abstract. In the urban environment, gas and particles impose adverse impacts on health of pedestrians. The conventional computational fluid dynamics (CFD) methods that regard pollutants as passive scalars cannot reproduce formation secondary lead to uncertain prediction. this study, SSH-aerosol, a modular box model simulates evolution gas, primary aerosols, is coupled with CFD software, OpenFOA...

Pavements in urban area absorb more sunlight due to the canyon-like geomorphology of geometry and store heat great thermal bulk properties concrete. Heat released from pavements warms up air, contributing island. Recently, uses cool reduce pavement temperature as an island mitigation have gained momentum. Understanding solar insolation a is important adopt right option for place. This study mea...

This paper examines the propagation of radio waves in so-called urban street canyons through formulations based on Geometrical Optics (GO) and Uniform Theory Diffraction (UTD). As this type environment comprises a flanked by tall buildings more or less equally spaced both sides (creating canyon-like morphology), estimating attenuation that signals may experience these scenarios is crucial to pl...

Microclimate in open space affected by the urban layout and spatial forms plays an important role in the outdoor comfort, thus the outdoor activities based on the comfort sensation will directly affected by the spatial forms. An outstanding open space should satisfy different requirements of outdoor activities and create relatively comfortable place.Most studies have been conducted on the...

Evapotranspiration of urban street trees is essential in mitigating heat islands due to its cooling effect. However, current shifts rainfall and temperature regimes towards drier hotter periods Central Europe have caused substantial water stress for trees. Quantifying subsequently managing these changing dynamics as well estimating evapotranspiration availability necessary but at the same time ...
