wind catchers have been served as a cooling system, used to provide acceptable ventilation by means of renewable energy of wind. In the present study, the city of Yazd in arid climate is selected as case study. From the architecture point of view, learning about wind catchers in this study is done by means of field surveys. Research method for selection of the case is based on random form, and ...

purpose estimating wind chill index as one of the indexes effective in body comfort, specifically for athletes and tourists interested in winter sports. methods meteorology data including temperature and the percentage of relative humidity of 6 synoptic stations of chaharmahal-bakhtiyrai province, iran from 1990 to 2007 were extracted from iranian meteorology site. in order to calculate the val...

the direction and speed of winds play an important role in the occurrence of pollutions and dust stormas well as location placement for the establishment of industries and the expansion of cities. yazd is a dry area of iran, and constantly exposed to the dust particles in the air; and this in terms of human life and health issues are of special importance. in this paper a day when due to the am...

Iran is a country completely dependent on fossil fuel resources. In order to obtain a diversity of energy sources, it requires other resources, especially renewable energy. Utilization of wind energy appears to be one of the most efficient ways of achieving sustainable development. The quantification of wind potential is a pivotal and essential initial step while developing strategies for the de...

Abstract The ability to accurately assess renewable energy resources is an essential prerequisite to integrating renewable energy technologies into the energy supply portfolio of a community. This study investigates the potential for wind energy development in Guelph, a growing mid-size city in Southern Ontario, Canada. Community awareness of energy has led to the development of a Community Ene...

in order to restrain the potential of wind energy, the first step is to determine the wind energy potential. in this study the wind data was used from the three-hour frequency recording of 10-year period (2002-2011). to predict the occurrence probability of each wind speed, the two-parameter weibull function was used. the goodness of fit test by chi-square test showed that the wind speed distri...

Climate data can be used in simulations to estimate the output of wind turbines in locations where meteorological observations are not available. We perform the most comprehensive evaluation of the NCEP CFSR reanalysis model hourly wind speed hindcasts to date, and the first for the UK, by correlating the data against 264 onshore and 12 offshore synoptic weather stations, over a period of 30 ye...

Renewable energy concepts are able to sustainably satisfy the world energy demand without any restrictions for the following generations. In these concepts the wind energy and wave/ocean current energy are important factors as the description and the prognosis of waves and currents is a complex issue, especially offshore. For the estimation of the average annual wind speed and thus the energy p...

abstract the averages of monthly minimum temperature and wind speed in 32 synoptic stations in northwest and west of iran used for calculate windchill temperature from november to april. then maps of spatial differences were drawn for every month and windchill regions classified by cluster analysis. keywords: iran, windchill, regionalization, classification.
