“…They allow the exploitation of the visible part of solar radiation (that is mostly transmitted) for daylight, while 134 a good fraction of the infrared radiation is absorbed by the PCM layer, thus reducing the solar gain in the IR range 135 (Goia et al, 2014b). The effect of thermophysical and optical properties of PCMs in double glazing has also been 136 numerically investigated (D. Li et al, 2016aLi et al, , 2016b. 137…”

Summary A two‐dimensional heat transfer model was proposed to numerically investigate the effect of enriching phase change material (PCM) with different kinds of nanoparticles on thermal performance of glazing windows in different seasons of the year. The results were presented in terms of liquid fraction of PCM, inner surface temperature and temperature difference between interior and exterior surfaces of glass window, and their occurrence times. The results showed that adding nanoparticles into PCM can promote the melting and solidification processes, extend the total time of PCM being in the liquid state, and raise the internal surface temperature of glass. However, in summer season, the internal surface temperature decreases and the total melting time respectively reduces by 7 and 1.5 minutes by introducing TiO2 and ZnO nanoparticles into PCM. Furthermore, the introduced nanoparticles do not have the same effect on the thermal performance of the window unit. While the inner surface temperature decreases by 0.82 K in summer by addition of TiO2 to PCM, it increases by 0.84 K in transition season and 0.89 K in winter season by utilizing ZnO nanoparticles. Although the nano‐PCM remains in the solid state in winter, the existence of nanoparticles can still increase the inner surface temperature.

“…The surface temperatures, transmitted irradiances, heat fluxes and comfort performance of both the PCM glazing and the reference fenestration were measured during extensive experimental campaigns, in order to assess the energy performance of the technology under different boundary conditions. Starting from experimental results, the effects of thermo-physical parameters on the dynamic heat transfer performance of PCM were also investigated by means of numerical simulation softwares [13,23,30,[43][44][45]. The semi-transparent property of a glazing roof containing PCM and the effect of zenith angle on the thermal performance were only analysed numerically by Liu et al [46,47].…”

Abstract:Building envelopes can play a crucial role in building improvement efficiency, and the adoption of Phase Change Materials (PCMs), coupled with transparent elements, may: (i) allow a better control of the heat flows from/to the outdoor environment, (ii) increase the exploitation of solar energy at a building scale and (iii) modulate light transmission in order to prevent glare effects. Starting from a literature review, focused on experimental works, this research identifies the main possible integrations of PCMs in transparent/translucent building envelope components (in glazing, in shutters and in multilayer façade system) in order to draw a global picture of the potential and limitations of these technologies. Transparent envelopes with PCMs have been classified from the simplest "zero" technology, which integrates the PCM in a double glass unit (DGU), to more complex solutions-with a different number of glass cavities (triple glazed unit TGU), different positions of the PCM layer (internal/external shutter), and in combination with other materials (TIM, aerogel, prismatic solar reflector, PCM curtain controlled by an electric pump). The results of the analysis have been summarised in a Strengths, Weakness, Opportunities and Threats (SWOT) analysis table to underline the strengths and weaknesses of transparent building envelope components with PCMs, and to indicate opportunities and threats for future research and building applications.
