Advanced glazing technologies for energy-efficient building envelope with reference to the Nano Aerogel windows

الملخص EN

The electric energy consumption for lighting, cooling, heating and ventilating the environment within buildings represents a significant fraction of the energy drain.

Building envelope, particularly the transparent elements plays a strategic role in the environmental performance and energy consumption of the building, significantly affecting the levels of indoor comfort.

In recent years there has been rapid development in the technology of the building envelope, especially the sphere of glass.

This paper aims, through an analytical, comparative study, at providing a review of the scientific literature that deals with the use of advanced glazing technologies, in view of letting architects, engineers, and builders know the scope of these technologies existing in the market and employ them to achieve energy efficiency in buildings.

Firstly, the paper reviews existing glazing systems showing their thermal and lighting performance.

Then, it investigates the effect of nanotechnology as a revolution technology on these types and its effect on developing high energy efficient windows such as Aerogel windows.

Finally, the paper concluded through a comparison between aerogel glazing and the other systems that, aerogel glazing can be a good alternative of glazing to reduce the building energy consumption.
