Effect titanium dioxide TiO2

Self Cleaning:
Titanium dioxide reacts with ultravioletlight, generates a photocatalytic reaction
significantly lower maintenance effort and a clean facade for many years
no ugly traces of dirt water from e.g. air vents
Smog (NOx) reduction results from the combustion of fossil fuels, e.g. from cars
purifies the air in immediate proximity to the building surface

Sustainable Construction : future Offices
Empty offices: 7,1 + 6,1=13,2 mio m2
(27% of market)
No steel framed office empty : Steelstructures are flexible/adaptable ->
renovation or other function possible
Long functional life = low environmental footprint
Steel structure has high residual value (re-use/recycling), they are demontable so low demolishing costs

SlideTata Steel
Sustainability is becoming key factor in construction
Innovative Steel/Alu products provides excellent opportunities to improve the sustainability of buildings.
Process developments (Hisarna, etc.) and
Product developments (HSS) reduce “Embodied” environmental impacts
Innovative steel solutions provide energy reduction “in Use”
Steel in construction means : High flexibility /adaptability -> extended building life
Highest re-use of building materials
Closed loop of all steel building materials
No downcycling of building materials, the only material
with option for Up-cycling -> “cradle to cradle”
Steel is the material for a Sustainable future
