Perspective of aerogel glazings in energy efcient buildings Tao Gao, Takeshi Ihara, Steinar Grynning, Bjrn Petter Jelle,Anne Gunnarshaug Lien Abstract The
2、 application perspective of aerogel glazings in energy efcient buildings has been discussed by evaluating their energy efciency, process economics, and environmental impact. For such a purpose, prototype aerogel glazing units have been assembled by incorporating aerogel granules into the air cavity
3、of corresponding double glazing units, which enables an experimental investigation on their physical properties and a subsequent numerical simulation on their energy performance. The results show that, compared to the double glazing counterparts, aerogel glazings can contribute to about 21% reductio
4、n in energy consumptions related to heating, cooling, and lighting; payback time calculations indicate that the return on investment of aerogel glazing is about 4.4 years in a cold climate (Oslo, Norway); moreover, the physical properties and energy performance of aerogel glazings can be controlled
5、by modifying the employed aerogel granules, thus highlighting their potential over other glazing technologies for window retrotting towards energy efcient buildings. The results also show that aerogel glazings may have a large environmental impact related to the use of silica aerogels with high embo
6、died energies and po- tential health, safety and environment hazards, indicating the importance of developing guidelines to regulate the use of aerogel glazings.

Introduction As an important building element in modern architecture, windows allow light, solar energy, and fresh air to promulgate the living area and offer an irreplaceable indooreoutdoor interaction, thus having a huge impact on th
