ArcelorMittal has entered a partnership with the world
leader in solar air heating, Conserval Engineering, to manufacture
SolarWall?, a technology that uses solar radiation to heat buildings
while reducing a building's heating costs by up to 50%.
SolarWall? will be produced by ArcelorMittal Haironville, part of
ArcelorMittal Construction France, for SolarWall Europe. The new
technology, which is entirely made of steel and integrated into the
building itself, is set to make a major contribution to meeting the EU's
2020 energy targets that aim to increase by 20% the use of renewable
The technology is already being used in thousands of commercial,
industrial and agricultural buildings around the world. A major
breakthrough in regulatory changes within the EU has now opened the
doors for widespread usage of solar air technologies such as SolarWall?,
in Europe. In addition to this, other European norms such as EN13339,
which stipulate the mandatory fresh air ventilation requirements for
buildings, have been put in place to address tighter building envelopes.
These changes fit well with the SolarWall? technology's ability to heat
large volumes of fresh air.
How does it work?
SolarWall? system is an integrated solar air heating system that uses
solar radiation to deliver naturally warmed air into buildings,
providing a source of renewable heat. Installed as an additional skin to
a building to create an air cavity, the SolarWall? technology consists
of a collector made of pre-coated steel developed by ArcelorMittal
Contrisson allowing high heat absorption and corrosion resistance, with
thousands of carefully engineered perforations spread across its surface
to collect the heated air.
As sunlight strikes the surface of the steel skin, the energy is
absorbed, heating the surface and creating a thermal boundary layer. In
turn, this layer of heated air which lines the face of the collector is
drawn through the perforations and into the building's ventilation
Once installed, the system requires virtually no maintenance over its 30+ year lifespan, helping further reduce costs.
'With increased pressure on private and public buildings to become
more environmentally friendly, there is a trend towards highly
efficient, holistic heating solutions which can be combined with
existing renewable technologies that aim to increase energy efficiency
and reduce CO2 emissions. The SolarWall? technology provides a new
solution for the commercial, industrial and tertiary sector to reduce
both their operating costs and their CO2 emissions', said ArcelorMittal
Construction's CEO, Jean Christophe Kennel.
John Hollick, CEO of the SolarWall group, added: 'We are very excited
to be partnering with ArcelorMittal and to be able to offer our
low-cost SolarWall? technology as a solution for Europe to meet its
renewable energy target.'
