Wind comfort and wind safety for pedestrians are important requirements in urban areas. Many city authorities request studies of pedestrian wind comfort and wind safety for new buildings and new urban areas. These studies involve combining statistical meteorological data, aerodynamic information and criteria for wind comfort and wind safety. Detailed aerodynamic information can be obtained usin...

despite the similar performance of bazaar1 in different cities of iran, there are some the skeletal differences between markets in different climates. the bazaar roof protects customers against natural events in any climate. the ceiling height and the sitting down of the bazaar`s floor are determined based on the need for air circulation and movement in various climates. hence, combination of a...

Wind catchers  are one of the most prominent masterpieces of Iranian traditional architecture. In arid climate, it can improve thermal comfort through natural ventilation. With the aim of recognizing the impact of this masterpiece on thermal comfort, this research examined the effect of wind on summer ambient temperature by employing PMV. To this end, wind catchers  of Salehi's House was select...

For this study, empirical data on the thermal comfort parameters (i.e. room space temperature, velocity and relative humidity) was collected for the computation of the PMV and PPD thermal comfort index for the three flat types. The study shows that wind ventilation has a great effect on the interior comfort condition. This is evident from the diurnal variations of PMV values. Majority of the da...

Wind environment in the populated built area especially in campus is important. This s tudy tes ted57 crossroad spots over of the whole campus in North China University of Technology (NCUT). The data of wind speed and direction were measured at fixed time and fixed place. The average, maximum values as well as the speed variation scale were calculated. Wind comfort criteria were adopted t...

The fluctuation characteristic of airflow is one of the important factors to influence the indoor thermal environment and human thermal comfort, which attracts researchers’ interest in these years. This paper introduces the recent researches on the fluctuation characteristics of airflow conducted in Tsinghua University. Results show that there exist obvious differences and interesting connectio...

weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...

OBJECTIVE To determine whether climate variability influences the number of hospitalizations for respiratory diseases in infants, children, and adults in the city of Campo Grande, Brazil. METHODS We used daily data on admissions for respiratory diseases, precipitation, air temperature, humidity, and wind speed for the 2004-2008 period. We calculated the thermal comfort index, effective temper...

Due to the complexity of built environment, urban design patterns considerably affect the microclimate and outdoor thermal comfort in a given urban morphology. Variables such as building heights and orientations, spaces between buildings, plot coverage alter solar access, wind speed and direction at street level. To improve microclimate and comfort conditions urban design elements including veg...
