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 Solar And 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 objective of 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 methods2.
Measurements and evaluation of optical and thermal properties of
aerogel as a material for window applications3. 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 of
window.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.
