Highly insulating aerogel glazing for solar energy usage

Aerogel insulation for building applications: A state-of-the-art review

“…A granular aerogel based window was developed by ZAE Bayern (Germany) [57][58][59]83]. Here, two types of granular aerogel are used in prototype windows: Semi transparent spheres with a solar transmittance T SOL of 0.53 for a 10 mm packed bed and highly translucent granulates with a T SOL of 0.88.…”

Nanogel Windows

“…It means that a 15-mm-thick interspace filled with granular aerogels could now have a cost of 60 US$/m 2 , that could become 22.5 US$/m 2 in 2020. The first daylighting system with granular aerogel in interspace consisted of a double-skin sheet of polymethyl methacrylate (PMMA) (Reim et al 2002). Two types of granular aerogel were used in prototype windows: semi-transparent, consisting of rather regular spheres, and high translucent granulates, consisting of irregularly fractured pieces spheres.…”

“…The energy benefits of using granular aerogel glazing are also discussed in the literature (Reim et al 2002). Referring to the German climate, the net heat flux during 1 month (from October to April) was calculated using a simulation model for three insulating materials (Fig.…”

“…An aerogel glazing with 20 mm aerogel thickness resulting in a centre U-value of Fig. 15 Monthly net heat fluxes of an aerogel glazing compared with a solar triple glazing and an opaque insulation calculated in three conditions: a north-oriented wall (a), an east-or westoriented wall (b), and a south-oriented wall (c) (Reim et al 2002) 0.5 W/m 2 K and a g-value equal to 0.75 was considered, and the results were compared to a triple-layered argon-filled glazing with two low-e coatings (U = 0.6 W/m 2 K and g = 0.46). The annual energy saving with aerogel glazing was approximately 1200 kWh/year, corresponding to 19 % of the energy for triple glazing (space heating demand equal to 5,040 kWh/year for aerogel, 6220 for triple glazing).…”

Preparation and Characterization of Thermal Insulating Coating for Buildings

“…Antimony-doped Tin Dioxide (nano-ATO),owning the advantage of ATO material and nano material at the same time, has the unique photoelectric property, resistance to ionizing radiation, good antireflection, infrared absorption, thermal stability and high ion selective exchange capacity for some elements, which can be used for preparing thermal insulation coatings, low-eglass for buildings, infrared absorption and insulation materials, antistatic plastic, radiation protection and antistatic coating material, fiber, electrode material, gas sensors and so on, so the preparation and application is attached more and more importance to [1][2][3]. Abroad, especially in Japan and America, the research of preparation and application of nano ATO material has been in the stage of mass production.…”
