TL;DR: In this article, the solar control properties of Cu2Se thin film coatings were investigated and the results are presented, which show that they exhibit superior solar control characteristics in certain respects over the metallic and PbS coatings and have comparable characteristics with CuxS films.
Abstract: Solar control coatings required for architectural glazing applications in tropical locations warrant much attention due to their vital role in energy conservation. The solar control properties of Cu2Se thin film coatings were investigated and the results are presented. It was observed that Cu2Se coatings have moderate optical transmittance and low reflectance in the visible region and high reflectance and low transmittance in the IR region. These characteristics are useful for the above purpose. The evaluation of their solar control parameters in the visible and IR region showed that they exhibit superior solar control characteristics in certain respects over the metallic and PbS coatings and have comparable characteristics with CuxS films.

Journal ArticleDOI
TL;DR: In this article, the authors presented a mathematical model and results of numerical simulations of a double sheet ventilated glass window, where the incident solar radiation heats up the air between the glass sheets creating buoyancy forces that induces upward flow of air.

Journal ArticleDOI
TL;DR: In this paper, a mathematical model with numerical simulations of the heat transfer across a simple glass window is presented, which is two-dimensional, transient based upon the energy equation with a source term to account for the solar radiation absorbed through the glass sheet.

Journal ArticleDOI
TL;DR: In this paper, the authors presented a study on a ventilated window composed of two glass sheets separated by a spacing through which air is forced to flow, and the model is one dimensional and unsteady based upon global energy balance over the glass sheets and the flowing fluid.

Journal ArticleDOI
TL;DR: In this paper, the thermal behavior of a ventilated double glass window with a solar reflective film is numerically investigated and validated against results available in the literature, and the results show that in order to reduce the heat gain in the internal ambient, the optimum spacing between the glass sheets should be at least 2.5 cm.
