“…Following the destruction of glazing systems, a resale for recycling procedure is carried out to generate revenue and lower the overall replacement cost. In any case, the replacement process is on hold until the decision-makers decide to renovate the entire building [30]. One of the most significant elements that aid the spread of the glazing industry is the availability of raw materials locally.…”

This study investigated the effect of different glazing types with various window orientations and Window to Wall Ratio WWR (10%, and 20%) on energy consumption in a typical room in an office building located in the hot climatic conditions of Aswan, Egypt. This case study was modelled and evaluated using Design Builder software to attain acceptable environmental performance for the study case while also investigating its impact on the amount of energy required for cooling, lighting, and heating. The researc h revealed that using an embedded nanogel layer between two layers of argon and two layers of single transparent glazing with (WWR=10%) resulted in a significant reduction in total annual energy use for all directions (North, West, South, and East), saving 3.66 %, 12.71 %, 6.51 %, and 4.18 % respectively when compared to a single layer of clear glass (3 mm). Furthermore, the results show that utilizing an integrated nanogel layer between two layers of argon and two layers of single transparent glazing has about the same efficiency as WWR=10% when WWR=20%. The study went into further depth to assist decision-makers by using the Pugh matrix to determine the optimum glazing among the proposed glazing types according to several studied criteria. It was discovered that utilizing an integrated nanogel layer between two layers of argon and two layers of single transparent glazing gave the best outcomes, obtaining a score of 3.54, which was higher than any score for the other proposed glazing types.

Liquid crystal (LC)-based research and its technological output vary from daily-use personal electronics and flat panels to switchable optical devices such as sensors. Optical and dielectric anisotropy is a key attribute of LCs, imparting functionality and broadening the scope of smart film systems to such products. Among LC smart films, the polymer dispersed liquid crystal (PDLC) smart film depicts an electro-optical (EO) composite sandwiched by transparent conductive oxide electrode-coated polyethylene terephthalate (PET) films. LC orientation and optical transparency in the composite are readily tuned by altering the electric field. The competitiveness of such PDLC devices reflects its favorable response time, energy conservation potential, and manufacturing convenience, all attributes that are readily endorsed by smart home appliances and areas of architecture and the automotive industry. In response to unrelenting market demands, sustainable, energy-efficient, and “greener” PDLC variants have appeared. Particularly worthy of mention are systems featuring transparency at zero field (reverse-mode). Others boast very high energy efficiencies (%80). In this chapter, the science and technology of PDLC, reverse-mode PDLC, and related LC smart films will be reviewed with a highlight on fabrication methods and operating principles. Market potential and research prospects compared to non-LC smart film technologies will also be touched upon.
