Who are you?

The Architect

Imagine that the concrete projects you’re working on can serve as a giant air filter. This idea might push boundaries, but you wish to deliver innovative ideas based on the latest trends and technologies. To make beautiful and well-functioned spaces for the population is a part of your DNA. However, the environmental angle might be a part of the agenda in every step you make in the projects’ development process. Photocat can help your project to stand out. We have solutions that make it possible for you to include intelligent photocatalytic surfaces.

Let’s add valued climate functionality to your next project.

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 indoors 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 today’s world main threats 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

Outdoor air pollution

Causes 4.2 million premature deaths worldwide

NO2 POLLUTION

Causes between 75,000 & 229,000 premature deaths in Europe

indoor air pollution

Causes 3.3 million premature deaths worldwide

Photocatalysis reduces NOx when we are exposed

Our everyday movement and the quality of the air are correlated. When most of us do our routine commute heading forth and back to work or school, the traffic is heavy. Coincidentally, we are exposed to high levels of air pollutants such as e.g., NOx & SOx.
Photocatalytic fluid can help reduce these harmful emissions.

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 building manufacturer delivers a product that holds a standard that effectively contributes to improved air quality.

An 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 Barcelona 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.

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