Frequency Selective Based Energy Saving Glass in Modern Smart Buildings Architecture

In this paper, a novel type of energy saving glass (ESG) is proposed for energy consumption management and mobile communication quality enhancement in modern buildings architectures. A typical ESG, which has full coating on one side, although has a direct effect on the IR wave (۱۲۰۰-۱۷۰۰ nano meter wavelength) transfer decrement, but simultaneously has destructive effects on mobile signal penetration in ۰.۸-۶ GHz range, yielding a poor mobile communication. The proposed ESG adopts some kind of slots, namely frequency selective surface (FSS) on its coated layer, acting as a filter. Adoption of such a structure both controls the heat energy transfer by IR wave, and also significantly enhances the mobile communication quality. The FSS unit cell is a ۲۰×۲۰ mm۲ configuration and on its coated layer a cross shaped slot is removed. The proposed design increases the IR wave transmission ۹% with respect to a full coated ESG, but enhances the mobile communication quality significantly
