Local air quality & our health<\/span><\/span><\/h4><\/h3><\/div>
<\/div>

The lack of fresh cool air in the city is felt most strongly on hot afternoons.<\/span> The high levels of particulate matter from rush hour traffic and the heat islands that occur due to the combination of lack of shade and strong sunlight have serious health effects.<\/span> These environmental influences hit children, the elderly and those with previous illnesses the hardest, because they are particularly prone to lung diseases and overheating.<\/span><\/p>\n<\/div><\/div><\/div>

PROBLEM FINE DUST<\/h1><\/div>
<\/div>
<\/path><\/svg><\/div>
<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

Air pollution is one of the biggest urban environmental problems and has serious implications for human health. According to the World Health Organization, over 91% of people in cities breathe polluted air with levels above recommended limits\u00b9. Polluted air, and especially the fine dust it contains, attacks all human organs, leading to everything from heart and lung problems to dementia, cancer and skin diseases. According to the European Environment Agency, 253,000 people die prematurely each year in Europe as a result of polluted air\u00b2, and more than 8 million\u00b3 worldwide.<\/p>\n

At Green City Solutions, we want to tackle this environmental problem head-on and make a positive contribution to sustainable, healthy urban development.<\/p>\n

With this goal in mind, we have developed the world’s first regenerative Bio-tech filter to quantifiably improve the air quality.<\/p>\n<\/div><\/div><\/div>

<\/span><\/span><\/div><\/div><\/div>
<\/div>

Air pollution can be caused by solid particles such as soot or gases like nitrogen dioxide.\u00a0In the city, particulate matter makes up a large part of air pollution. It consists of a complex mixture of tiny particles.\u00a0The nasty thing about it is that you can usually neither see nor smell it.<\/p>\n<\/div>

Health impact<\/h2><\/div>
<\/div><\/div><\/div><\/div><\/div>

Depending on the particle size, fine dust penetrates the body to different depths. Regular exposure to fine dust causes the tiny particles to accumulate in the body over the years and can trigger a range of diseases. The most common health consequences include lung and cardiovascular diseases. But even short stays in polluted cities already lead to a significantly increased risk of a stroke, as reported by the specialist magazine ‘Neurology’<\/a>.<\/p>\n<\/div><\/div><\/div>

PROBLEM HEAT ISLANDS<\/h1><\/div>
<\/div>
<\/path><\/svg><\/div>
<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

The lack of air circulation and comprehensive greening concepts in the city not only leads to fine dust hotspots, but heat also clogs up between buildings on hot days. So-called urban heat islands develop. Even at night, it often does not cool down because the dark buildings and streets store and release the heat. Advancing climate change is adding fuel to the problem. Serious damage to human and natural health is the result. The cardiovascular system in particular suffers from the enormous heat stress in cities. According to the European Environment Agency, heat waves will soon be responsible for 130,000 premature deaths in Europe every year.<\/p>\n

We are creating green oases of fresh air that are not only pleasantly cool, but also smell wonderfully like forest.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

<\/div>

The main causes<\/h2><\/div><\/div><\/div>
<\/div>

Heat islands are formed in the city through a combination of factors. The absence of greening concepts and adequate air circulation is fundamental to their creation. Advancing climate change is increasingly exacerbating the problem.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

<\/div><\/div><\/div>
<\/i><\/div>

Lack of greening<\/h2><\/div>
<\/div>
\n

Dark surfaces such as roads and buildings store heat and additionally heat up the air. Innovative greening concepts on streets and buildings can reduce the temperature in the surrounding area.<\/p>\n<\/div><\/div><\/div>

<\/i><\/div>

No air circulation<\/h2><\/div>
<\/div>
\n

Due to inadequate air circulation, the hot air trapped between the streets often struggles to exchange with the cooler air emanating from parks and green spaces. This stagnation results in the accumulation of heat, giving rise to urban heat islands.<\/p>\n<\/div><\/div><\/div>

Heat islands and fine dust<\/h2><\/div>

The one causes the other<\/h3><\/div><\/div><\/div><\/div><\/div>
<\/div>

The lack of fresh cool air in the city is felt most acutely during hot afternoons. A lack of air circulation and insufficient greening concepts in the city not only lead to fine dust hotspots, but heat also clogs up between buildings in the summer. Notably, problematic heat accumulation occurs predominantly in areas with elevated fine dust concentrations. This poses a heightened risk to vulnerable groups such as children, the elderly, and individuals with pre-existing conditions, who are particularly susceptible to respiratory issues and overheating due to these environmental factors.<\/p>\n<\/div>
