Abstract

In this paper, experimental results have been reported on proposed window systems comprising of cavities filled with air and water. Experiments have been performed on smaller laboratory samples with the help of Perkin-Elmer Lambda-9 double beam spectrophotometer. The shading co-efficient of water filled system alone has been found to be appreciably lower than that of an air-filled system; the luminous efficacy has also found to be higher. However, because of higher thermal conductivity, water filled glazing systems have been found to have higher thermal transmittance values. Therefore, an optimal system combining air and water columns has been fabricated and studied. In this paper, an attempt has also been made to analyze the energy and environmental benefits for possible applications of solar efficient glazing systems.
