What is sustainability?

Although the word "sustainability" is often perceived as the latest buzzword, it has a long history. The development of this history often dates back to disasters concerning the use of nature. Confucius described the fundamentals of sustainability around 500 B.C. He advised his fellow men to limit themselves to essentials due to the limited supply of natural resources. The term German term for sustainability is "Nachhaltigkeit" and was coined by Hans Carl von Carlowitz. In 1713, he talked about sustainable forestry operations, proposing that a new tree be planted for every tree felled. Today's definition is based on three pillars: ecology, economy and social responsibility. These three pillars are closely related and interact with one other. Sustainability occurs when ecology, economy and social responsibility are in balance.

Why sustainability?

Ecology: the aim of ecology is the conservation of nature, raw materials and resources. Future generations should find the same ecological quality as today's generation.


Economy: to ensure a sustainable economy, constant economic growth is necessary as well as taking into account entire life cycles. For example, it is not enough just to evaluate the acquisition costs.


Social responsibility: a decisive aspect with regard to social responsibility is, for example, the prohibition of human trafficking, child labour etc. Furthermore, the health of fellow human beings naturally takes precedence. This means that not only the usage of non-hazardous materials, but also assistance for persons with personal restrictions should be taken into account. In addition, attention should be paid to the importance of light, temperature, fresh air, noise and other influences on the building's occupants.
