PHASE CHANGE MATERIALS FOR DAY LIGHTING AND GLAZED INSULATION IN BUILDINGS

Abstract

This paper presents the experimental solar transmittance measurements of commercial grade Phase Change Material (PCM). The effects of ambient temperature, solar radiation and thickness on transmittance have been studied. The study indicates that the PCM has higher transmittance than water. High transmittance, low thermal conductivity and high latent heat of fusion make it suitable transparent insulating building material (i.e. Window, sky roof etc.).
