The link 'plant' has gained importance in architecture as a media against over-technicalisation and the alienation to nature. People react positively towards indoor plants. Above this, plants take on important functions of well being such as acclimatisation, the binding of dust and harmful substances and the reduction of noise. At the same time they support stress reduction. People are drawn to plants and have a close relationship to them, especially in the concrete desserts known as towns. Life has been revolutionarily changed through the cultivation of plants by humans of the early epoch. The vital comprehension of the interplay of man and plants though, has been lost due to industrialisation.
Indoor plants also influence the perception of the persons working and living in the related building. Hereby, smells play an important role. Because though, people react differently to smells, strongly smelling plants should only be used sparingly.
As the sun is the only unproblematic source of energy that we have and as it is unrenounceable for our lives, a co-operation between sun and plants should form a new kind of architecture. During the planning of a building, the guidelines of solar architecture must be taken into consideration. Which climatic zones does it have, how much light is available and how is the building constituted. To carry out the conversion in the best possible way, interdisciplinary co-operation must take place. For example, during one project, a heating and ventilation engineer, a garden layout specialist and an electric-planner are involved.
