“…In recent years, VIPs are getting more and more popularity in building industry because of their extremely low thermal conductivity and ultra-thin thickness that allows the buildings to conserve energy and have more habitable space as well [11]. However, the present VIPs have two main drawbacks, one is high cost and the other is unstable thermal conductivity over their useful lifetime [12].…”

“…Many approaches have been made referred to the thermal insulation systems for the peripheral structures of buildings. Dozens of thermal insulation systems for the external walls of buildings were developed [2][3][4]. Specifically, by using an insulating layer made of porous inorganic materials, the external thermal insulation composite systems with Glazed Hollow Bead thermal insulation mortar (ETICS GHB) are characterized by the high thermal insulation and fireproof performances.…”

This research analyzes the thermal and strain behavior of external thermal insulation cladding systems (ETICS) with Glazed Hollow Beads (GHB) thermal insulation mortar under hygrothermal cycles weather test in order to measure its durability under extreme weather (i.e., sunlight and rain). Thermometers and strain gauges are placed into different wall layers to gather thermal and strain data and another instrument measures the crack dimensions after every 4 cycles. The results showed that the finishing coat shrank at early stage (elastic deformation) and then the finishing coat tends to expand and become damaged at later stage (plastic deformation). The deformation of insulation layer is similar to that of the finishing coat but its variation amplitude is smaller. Deformation of substrate expanded with heat and contracted with cold due to the small temperature variation. The length and width of cracks on the finishing coat grew as the experiment progressed but with a decreasing growth rate and the cracks stopped growing around 70 cycles.

“…VIPs have thermal resistance values, at the centre of the panel, up to 10 times or more than those of conventional thermal insulation materials [51]. Energy efficient VIPs present thin but highly effective insulation solutions, to reduce thermal losses for both new and renovated buildings [52]. The environmental impact of transparent aerogel has been assessed in study [53].…”

Abstract:The contribution of embodied energy (EE) and greenhouse gas emissions to building materials and structures has been recognized as significant, especially for nearly-zero energy-efficient buildings. The aim of this paper is to evaluate the composition of non-transparent structures of building envelopes from energy and environmental perspectives using the life-cycle assessment method. The study assesses environmental indicators such as EE from non-renewable resources and CO2eq and SO2eq emissions from proposed assemblies of building structures for nearly-zero energy wooden houses. Material compositions are also calculated in terms of selected thermal-physical aspects (U-value, phase shift of thermal oscillation, relaxation time) to ensure the reduction of energy consumption during building operation. All results are compared using a multi-dimensional evaluation approach through mathematical methods. The multi-criteria decision analysis demonstrates that material optimization of building structures is possible to ensure a marked reduction of the energy consumption and carbon footprint of buildings.
