WE CLEAN THE AIR WE BREATHE

IN HOMES & CITIES THROUGH LIGHT

THE ARCHITECT & BUILDING PROFESSIONAL

We strive to improve the environment by continuously innovating and pushing boundaries for known standards. In the creation of a healthier and more sustainable future we engage public authorities and companies to think and be innovators. Together with our partners we promote a cleaner environment through active surfaces that reduce air pollution in cities by using light.

More than 1,000,000 m2 of applied surfaces

Degrading more than 31.8 kg/NOx per day

apx. 14,200 kg/NOx degraded in total

WHY IMPROVE INDOOR AIR QUALITY

Poor air quality is directly linked to several different illnesses: heart disease, stroke, chronic lung disease and cancer, asthma. Especially children and elders are at risk. Air pollution causes ten times more premature deaths per year than traffic accidents.

“Cleaning up the air we breathe prevents non-communicable diseases as well as reduces disease risks among women and vulnerable groups, including children and the elderly…” Dr Flavia Bustreo, WHO Assistant Director-General Family, Women and Children’s Health

Our living environments are becoming increasingly air-tight. This is good from an energy perspective, but from an air quality perspective it means we are locking in pollution stemming from a variety of sources in our building such as building materials, furniture, paints, cooking, cleaning agents, smoking and electrical appliances. All of which are known sources of sources of NOx and VOCs emissions. As we spend 16 hours daily inside the quality of the air we breathe is of critical importance.

In addition to the indoor sources of pollution a danish study found that appx. 75 % of outdoor pollution made its way into city apartments in the center of Copenhagen.

WHY IMPROVE OUTDOOR AIR QUALITY

More than 7 million people die prematurely due to air pollution worldwide (United Nations, 2016). In Europe alone the number related to premature deaths due to poor air quality is more than 400,000. Approximately 90 % of the worlds total population is exposed to hazardous air quality. Poor air quality is one of todays world main threaths to human health.

“As a society, we should not accept the cost of air pollution. With bold decisions and smart investments in cleaner transport, energy and agriculture, we can both tackle pollution and improve our quality of life,” said EEA Executive Director Hans Bruyninckx

PHOTOCATALYSIS REDUCES NOx WHEN WE ARE EXPOSED

In most cities the air quality is highly correlated with our everyday movement. When we take the bus, bike or walk to work, well, that is when traffic is at its heaviest and coincidentally that is when we are exposed to high levels of air pollutants such as NOx. The same goes for when we head back. Air quality is poorest during the day. Photocatalysis is activated by daylight.

HOW THE ACTIVE REDUCTION OF AIR POLLUTION RELATES TO THE UN SUSTAINABLE DEVELOPMENT GOALS

We strive to improve the environment by continuously innovating and pushing boundaries for known standards. In the creation of a healthier and more sustainable future we engage public authorities and companies to think and be innovators. Together with our partners we promote a cleaner environment through active surfaces that reduce air pollution in homes and cities by using light.

We provide a long lasting and cost-efficient technology to reduce NOx and other pollutants where we breathe.


Reducing air pollution can help families become more healthier, save on medical expenses, and improve productivity.


Air pollution can cause crop damage and affect food quality and security.


Air pollution poses a major threat to human health. It is linked to respiratory infection and cardiovascular disease. It causes increases in population morbidity and mortality.


Pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) from open fires and the combustion of fossil fuels mix with precipitation causing harmful acid rain that can compromise water quality.


Air pollution impacts on health, crop and forest yields, ecosystems, the climate and the built environment, with consequences for productivity and economic growth. Ambient and indoor air pollution also has negative effects on the working environments and its safety.


Urban areas significantly contribute to air pollution. Making cities sustainable could progressively improve the air quality.


Deposition of air pollutants on water may negatively affect its quality and life under water. It can lead to eutrophication and acidification of fresh water bodies, and accumulation of toxic metals and Persistent Organic Pollutants (POPs) in fresh and marine waters.


Emissions from combustion of fossil fuels mixed with precipitation cause acid rains that pose a major threat to forests and ecosystems.

HOW TO IMPLEMENT IN YOUR NEXT PROJECT

In order to ensure that the photocatalytic technology applied is of the highest standard we propose that you include a condition in your next tender stating that the material is tested according to an ISO 22197-1. The purpose is to enforce that the buidling manufacturer delivers a product that holds a standard that effectively contributes to improved air quality.

One example of photocatalysis being implemented in a city as a consistent means to improve air quality is found in the city of Barcelona:

 

Plan to improve air quality in Barcelone 2015 – 2018

EL12 – Air purification using photo-catalytic materials: Using construction materials with the ability to reduce atmospheric pollutants, such as NOx, PM10, benzene and carbon oxides (Barcelona Regional. Agència Desenvolupament Urbà Gerència Adjunta de Medi Ambient i Serveis Urbans, 2015).

We recommend that architects, engineers and other building professional specify the following criterias.

  1. Building Materialsmust be treated with an active photocatalytic dispersion of ultrafine titanium dioxide.
  2. The applied ultra fine titanium dioxide dispersion must be environmentally friendly and should be waterbased.
  3. The Building Material must be photocatalytic and tested according to the ISO standard 22197-1.
