The Impact

Solar radiation is the cause of large heat gain in glazed buildings particularly in the tropics, thus the aim of this study is to investigate the impact of a sustainable water film on glazing transmittance to solar radiation. The experimental investigation measured two parameters, namely, type of glazing and solar radiation intensity, utilizing glazed façades oriented west in two full-scale rooms. It was found that the water film on the glazed façade increases the transmittance of solar radiation behind the glazing by 2% - 6.8% depending on the solar intensity and glass type, while the indoor temperature was reduced. The study concluded that the increment of the solar radiation (300–2500nm) transmittance is an increment in the range of the visible light (daylighting).

Method Of Determination

AbstractThe paper considers method of determination of solar radiation amount falling on arbitrarily oriented surface of a structure. Provided method allows calculation of influence of structure’s geographical coordinates, spatial orientation of structure’s surface, day of year and time of day on received amount of solar radiation. The method is intended for determination of thermal stresses and deformations of sheet steel structures caused by action of direct solar radiation. Examples show usage of provided method.
