Objective
Utilization of solar energy in new low-energy buildings and in existing buildings takes mainly place by the transparent area ofthe thermal envelope ie the windows. However, the window area is also the weakest part of the thermal envelope in general. The contradiction between transparency and insulation at windows must be overcome in order to reduce the energy consumption for space heating.
A very promising method is to apply monolithic silica aerogel as transparent insulation material in glazings for windows. The glazing consists of an aerogel tile between two glass panes and the unit sealed at the rim. The gas pressure within the glazing is below 50 - 100 hPa ie a rough vacuum.
The main project objectives are:
1) to make the pre-industrial elaboration process evaluation for the chemical part (aerogel process) and the glazing assembly process of aerogel window and
2) to estimate the energetic interest of such glazings.
Other objectives are:
- Flat aerogel sheets of about 60 x 60 x 2 cm3 with a solar transmittance of90 % or more and the lowest heat conductivity ever reported for suchmaterial.
- The aerogel material exhibits only negligible image blur ie the opticalquality is at the same level as ordinary glass panes.
- Prototypes of 60 x 60 cm2 evacuated aerogel glazing (aerogel thickness of20 mm) made by the proposed process and having a centre heat losscoefficient (U-value) below 0.4 W/m2 K, an overall U-value below0.5 W/m2 K and a solar energy transmittance (g-value) above 75 %. Finally,the lifetime ofthe glazing with respect to maintaining the gas pressure below50- 100 hPa will be at least 30 years.
- Technical and economic evaluation of an industrial production of aerogelglazings for windows.
At the end ofthe project, it is expected that the following are developed: A supercritically CO2 based process with recovery, that can give ilat aerogel tiles of 60 cm square as well as a glazing assembly process, suited for an industrial production, for the same size.
It is expected that after the end of this project, about three to five years of further development with respect to scaling up the aerogel production process and the glazing assembly process will be needed before an industrial, full scale production of aerogel glazings windows can be started.
