Full scale investigation on aerogel windows exposed to real climatic conditions

The aim of the project is to investigate prototypes of aerogel windows mounted in a south facade of an experimental building on campus. The investigations will include an parallel evaluation of the energy balance and influence on the indoor thermal comfort for a room with an aerogel window and two rooms with different commercial low-energy windows. Beside the thermal investigations special attention will be paid to condensation on the outdoor surface of the glazings. Outdoor surface condensation is expected to be a major problem for window glazings with low centre U-values.
The investigations will be made over a period of 2 - 3 years in order to observe the long term stability of the aerogel glazing when exposed to wind load and thermal stress. The project will serve as a limited demostration of aerogel glazings.
