Additional benefits
– Air purifier
– Anti odour
– Antimicrobial
– UV filter
'Anti Smog: An Innovation Centre in Sustainable Development':
Prototype, Paris, France. The exterior is fitted with 250 square meters of
solar photovoltaic panels and coated in titanium dioxide (TiO2). The PV
system produces on-site electrical energy while the TiO2 coating works
with ultraviolet radiation to interact with particulates in the air, break down
organics and reduce air born pollutants and contaminants.
