Climatic conditions have a significant impact on the energy consumption of  buildings. Also check the angle of the solar radiation on buildings and controlling the amount of heat absorbed on building shell during the year have significant impact on building energy efficiency. The aim of this study was to investigate the effect of orientation of the building on the energy consumption and to this...

Solar energy is receiving lots of attention because it is one of the cleanest, cheapest and most available energies in the world.but solar radiation in different parts is changing, thus, identifying appropriate locations for implementation of solar energy is necessary. Accordingly the aim of this study was to analyze the potential of solar radiation and land surface temperature on the Loot dese...

The aim of this study was to provide a reliable estimate of the amount of solar radiation in Kermanshah province by using “Liu and Jordan” model in order to develop solar sites. The amount of atmospheric elimination in each month was calculated using an index called clearness index () and the results were applied on different slopes, aspects and heights. Then, according to the obtained results,...

In this study, the concentrations of micro and nano-sized pollutant particulates in the air and simultaneous sun radiation were monitored and then the effects of air pollutant particulates on sun radiation were evaluated. Measurements were done during summer season in the Karaj, Meshkin-dasht. Statistical investigation of the collected data, resulted three equations, indicating the effects o...

Introduction The human need for energy is continually increasing and the limited sources of fossil energy are reducing. The indiscriminate use of fossil fuels pollute the environment and threaten life on the earth. Besides, because of difficult terrain, unfavourable topographical conditions and inaccessibility of some mountainous roads to national electricity network or high costs of these s...

Environmental subjects, in general, and energy issues, in particular, do not have a prominent role in rural research projects in Iran, and this is accompanied by negative environmental consequences, such as excessive energy consumption in rural housing. A significant amount of energy in villages is used up by dwellings, and the form of rural fabric is a major factor affecting this issue. Most o...
