PURETi is a surface treatment that uses UV-PCO (ultraviolet photocatalytic oxidation) with ultraviolet light to transform treated materials into self-cleaning surfaces. Benefits include reducing the water, chemicals, and energy used in cleaning by at least 50%, plus significantly reducing air pollution. Light energy from the sun (or fluorescent lamps) energizes a mineral called anatase titanium dioxide (TiO2) in the treatment product, which in turn accelerates the natural chemical breakdown of organic molecules comprising grime, bio-film, smog and volatile organic compounds.
An independent laboratory study was conducted at Stony Brook University by Professor Alexander Orlov, Ph.D. “Experiments conducted in our lab found that PURETi UV-PCO technology is able to eliminate almost 80% of harmful NOx emissions by using light energy from ultraviolet light,” said Orlov. NOx (nitrogen oxides) can react with volatile organic compounds to form Ozone, which can have adverse health effects.
The treatment helps keep glass free of unattractive organic films, and when applied to cool white roofs, it reduces reflectance loss caused by the growth of biological matter and other soil.
Projects using this treatment include the Los Angeles Community College District (with a >$4 billion budget, arguably the largest green building project in the country), which is treating a million square feet of building roofs, windows, and cement and brick facades and plans to treat approximately 15 million square feet on nine separate campuses over the next three to four years. Goshow Architects used it in its newly renovated Manhattan office.
