19 June 2018 - ArcelorMittal has unveiled a
radical new concept for the use of steel in construction, which
will facilitate the next generation of high performance buildings
and construction techniques and create a more sustainable
life-cycle for buildings.
Known as Steligence®, the concept
revolves around the idea of buildings as holistic entities where
all aspects of design are considered in an integrated way, as part
of the whole. As such, it proposes the need for better dialogue
between various specialist architectural and engineering
disciplines, recognizing not only specialist expertise, but also
the need for enhanced co-operation between experts. Steligence®
further suggests that the use of best available technology in
steelmaking, as well as modularization of steel components in
buildings where possible, has the capacity to generate efficiency
gains in the design, construction and configurability of buildings
as compared to those using traditional construction methods.
Additionally, because steel is
infinitely recyclable, Steligence® sets the stage for architects to
consider the life-cycle, recyclability and, ultimately,
re-usability of a building and its components at the earliest point
in the design process.
This new approach to construction
from ArcelorMittal has been brought about by real advances in
technology which now make steel an even more attractive material
for construction than was previously the case. As such, the
Steligence® concept has the potential to drive significant
architectural and sustainability benefits.
These benefits include more
building storeys within a given height than is the case with
traditional building systems and materials; less deep and therefore
less costly foundations due to the lower weight of steel buildings
compared with traditional materials; and far longer uninterrupted
spans between columns, resulting in much better flexibility of
interior floor layout.
In addition, buildings designed
using the Steligence® philosophy will be easier to assemble (and
potentially disassemble) and therefore quicker to build, leading to
significant efficiencies and cost savings for the construction
sector.
While steel's infinite
recyclability potential is clearly superior to that of alternative
materials, even then there are associated costs given the energy
necessary to melt and re-form. In this context, design where
possible using modular steel components can enable re-use rather
than re-cycling of steel components in new buildings at the end of
life of the original building. This 're-use' possibility gives
steel a huge advantage over traditional building materials,
particularly as regulations strengthen regarding the sustainability
credentials of buildings.
Steel already plays a big role in
the circular economy. Steligence® will enable the construction
industry and buildings themselves to play an even more significant
role in it.
Speaking at a launch event in
London, Greg Ludkovsky, ArcelorMittal's global head of research and
development, said: "As climate, energy and resource scarcity
intensifies, win-win solutions like Steligence® become imperative
for business and society at large. Buildings play a huge part in
all our lives, so creating a construction concept that improves
their social, economic and environmental impact while dramatically
enhancing their functionality and aesthetics has been a huge but
important challenge."
"Steligence® is the culmination of
several years' intensive scientific, independent peer reviewed
research to develop specific-use steel for the construction
industry. By combining this R&D with extensive consultation of
leading players in the construction industry, we have landed on a
radical new approach to construction which is underpinned by a
clear philosophy: to build a sustainable business around a
sustainable construction industry that delivers for future
generations."
Notes to editors:
Ten key benefits of the Steligence concept
Economic
-
Optimal space and height. Use of the
Angelina(TM) beam and CofraPlus 60 compact floor enables greatly
reduced building height resulting in average 11% cost savings
across façade, stairs and core elements.
-
Lighter weight foundations. Steel foundation
solutions, less than half the weight of equivalent structures, can
result in an average 39% foundation cost saving,
like-for-like.
-
More flexible office space. Using the
Angelina(TM) beam, un-interrupted spans of up to 13m can be
achieved. Consequent reduction in columns allows easy
reconfiguration of office space and therefore increased rental
value.
-
Speed of construction. Best in class steel
solutions using 13m spans can be erected up to twice as fast as
concrete equivalents in 8m and 5m spans resulting in up to 24%
construction costs saving.
-
Cost of ownership. Total costs of building
ownership, taking into account all economic benefits, are at least
15% less than those constructed using alternative materials, when
all components of the concept are applied.
Environmental
-
Lower environmental impact. With comparatively
low environmental impacts and higher recycling rates than other
building materials, steel is the first choice for sustainable
construction. Steel enableS access to the green building market
with consequent increase in property value.
-
Sustainability ratings. Buildings using
ArcelorMittal steel solutions attain higher levels of certification
in building rating schemes such as BREEAM and LEED than those built
with traditional materials.
Social
-
Improved comfort. Steel buildings provide a more
comfortable environment for building users due to optimised thermal
behaviour during warm weather.
-
Site traffic. Steel requires fewer site
deliveries than comparative materials, resulting in less traffic
congestion and so reduced impact on the urban environment.
-
Creativity. Steel cladding solutions offer an
unparalleled choice of creative, attractive finishes, adding
materially to the urban landscape.
