A Systematic Review and Classification of Glazing Technologies for Building Façades

Abstract

High-performance glazing technologies are essential for achieving the occupant comfort and building energy efficiency required in contemporary and future buildings. In real-world applications, glazing façades are selected from a steadily increasing number of glazing technologies. However, the authors could not identify a systematic and comprehensive review and classification of glazing technologies in the literature. This creates a barrier when comparing typologically different glazing technologies and combining multiple technologies in a glazing unit. This paper provides a systematic review and classification of established and emerging glazing technologies based on publications from 2001–2022 which were interpreted following the PRISMA methodology. This study reveals that the majority of high-performance glazing systems used in practice are in multi-layer glazing configurations and that the glazing system performance can focus on including additional and multiple functionalities, which aim at improving overall building performance. It was also found that there is a large potential for improvement of multilayer, evacuated, aerogels, electrochromic, and solar cell glazing by incorporating other technologies or innovative materials in multi-layer glazing units for either improving existing technologies or for the development of new ones. However, their longevity, robustness, and cost affordability should be ensured.

A Review of Energy Efficiency Interventions in Public Buildings

“…The design and quality of building openings, or fenestration, are paramount in energy conservation [12,61,84,86,88]. Modern advancements in materials, such as aerogel and vacuum glazing, offer exceptional insulation [89,90,92]. Moreover, strategically placing and designing windows can optimize natural light while minimizing heat gain or loss [32], while some researchers have proposed movable insulation systems for windows [85].…”

Smart Glazing Systems vs Conventional Glazing: A Comprehensive Study on Temperature Control, Daylighting, and Sustainability

“…Liquid crystal (LC) glazing represents another electroactive medium where the glass appears translucent when the power is off and completely transparent when turned on. LC glazing consists of a polymer matrix sheet sandwiched between two transparent plastic electrical conductors [35]. In the absence of applied voltage, liquid crystals scatter light due to their non-alignment [36].…”
