“…Glass windows affect the building by heat transmission and compromised thermal comfort [133][134][135][136][137][138][139] and studies by Chaiyapinunt et al, showed that the thermal comfort was dependent on the optical properties (total transmittance and total absorbance) and the overall heat transfer coefficient of type of glass used in windows [140]. Singh et al, have also studied the impact of different glazing systems on human thermal comfort in an Indian scenario [141].…”

“…However, the study is not adequate for warm climates and the mathematical model is not detailed, for it does not consider the window's width or the term for radiation losses explicitly. The predicted theoretical thermal performance of chemically deposited coatings on window glazing for controlling the transmittance of solar radiation has recently been reported by Estrada-Gasca et al [1,2]. This steady state theoretical model essentially deals with the redistribution of the component of the solar radiation absorbed in the glass to the exterior and to the interior of a room and allows us to calculate the shading coefficient and the solar rejection factor.…”

The experimental validation of a mathematical model that predicts the shading coefficient (SC) and the solar rejection factor (SRF) of various types of solar control coatings is presented. The model allows us to input the solar absorptance and predict the temperature of the solar control glazing as a function of the thermal emittance and exterior temperature for typically AM2-solar radiation. With the additional knowledge of the solar reflectance, the SC and SRF are calculated. The model is tested using a chemically ZnS- solar control coating deposited on a 6 mm clear glass and the results are compared with those for commercial glasses.

“…Chemically deposited solar control coatings met this requirement. It has been reported [1,2] that solar control coating reduces the entrance of solar radiation through windows, even though the glass increases its temperature because of its absorptance. The shading coefficient decreases by 50% with the use of the solar control coatings [3].…”

“…This leads to a more precise approach to predicting the thermal performance of coatings developed on laminated glass sheets. Indeed, this kind of mathematical modelling has already been applied with success to the case of a single glass sheet with solar control coatings [2,3]. In this paper, we present a transient one-dimensional mathematical model for the thermal performance of the chemically deposited solar control coating in a laminated glass for automobiles and its experimental verification.…”

A transient one-dimensional mathematical model allowing the prediction of the thermal performance of laminated glazing with and without chemically deposited solar control coating and its experimental verification are presented. A normal laminated glass is composed of two 3 mm glass sheets with a thin polymer layer between them. For the experimental verification, the coating used was a thin film of Cu x S added between the polymer layer and one of the glass sheets. A constant normal incidence of air mass 2 solar radiation was assumed. Conductive heat transfer within the glass sheets and convective and radiative heat transfer through the inside and outside are considered. Using the optical properties of glass, polymer and solar control coating, the redistribution of the absorbed component of the solar radiation and the shading coefficient (SC) are calculated as functions of the convective heat-transfer coefficient for the outside (h o ). Variations of the theoretical inside glass temperature (T g1 ) for h o and SC for the solar absorptance (α) of the film varying from 0 to 0.9 are presented. For the array with the highest solar absorptance of the solar control coating (α = 0.9), the decrease in T g1 was from 49 down to 27 • C, a temperature drop of 22 • C as h o increases from 5 to 100 W m −2 K −1 . The SC for the array with α = 0 is almost constant with h o and close to unity, whereas for the array with α = 0.9, the SC drops by 62% from 0.58 to 0.22 as h o increases.
