N2 - The report summarizes the work that has been carried out within
the project "B1 AEROGELS" as a part of the IEA SH&CP Task 18
"Advanced Glazing and Associated Materials For SolarAnd Building
Applications". By providing at the same time thermal insulation
and transparency the silica aerogel is a very attractive material
for the purpose of improving the performances of windows.
Nevertheless a lot of problems have to be solved on the way from
concept to the developed product. The B1 Aerogels project deals
with some of these problems. The objectiveof the B1 Aerogel
project is: "To develop the scientific, engineering and
architectural basis which will support the appropriate use of
aerogels in windows, solar collectors and passive solar
applications, with the aim of saving or producing thermal energy
for use in buildings". This objective is in very good agreement
with the general scope of task 18 but where Task 18 focuses on the
development and use of advanced windows in general, the B1 Aerogel
project is focused on the application of aerogels only. The scope
of the aerogel project was to perform an evaluation of the aerogel
material and to identify some of the strengths and weaknesses that
can be expected of aerogel as a material for window applications.
It was not a part of the project to make a further development of
the aerogel material. The project was carried out in three main
steps: 1. Collection of information on aerogel production methods
2. Measurements and evaluation of optical and thermal properties
of aerogel as a material for window applications 3.Construction of
an aerogel DGU and measurement of key performance parameters. The
goal for the aerogel DGU was to reach a Total Solar Energy
Transmittance above 0.75 and a U-value below 0.5 W/m²K. These are
values that can not be simultaneously reached by any other type
ofwindow. The project has been carried out in a cooperation with
several other Task 18 projects: The aerogel project has collected
and distributed aerogel samples for other Task 18 projects.The B11
and B13 have performed optical measurements on aerogel samples as
well as on the aerogel DGU that was developped during the project.
B12 and B14 have measured the g-value and the U-value respectively
of the aerogel DGU. Furthermore calculations of the energy saving
potential by using aerogel windows in selected residential and
commercial buildings under different climatic conditions were
carried out as part of the A2/A3 project. The B1 Aerogel project
has been carried out with partition of the following nations:
Denmark, Finland, France,Germany, Japan, Norway, Sweden and the
United Kingdom.
