urban greening

How can we bring nature back to urban high-rise buildings, also reducing energy consumption?

BREATHING WALLS A green space for residents on the facades China, Beijing, Tsinghua University Even in a high density town like Beijing, such a solution as "Breathing walls" can introduce the so-called “natureimitating” architecture. This new “Bio-tech” architectural design and environmental-greening and care service utilizes the recycling of wastewater for hydroponic plants in order to build a high-rise green house with air-conditioning. The building is covered with a layer of transparent glass and plants grow between this and the building wall. The idea is to make use of the circulatory convection of air and the temperature adjusting power of plants to create a thermal balance and improve air quality.

the basis of natural processes, but is aided and supported by the use of the best technology available. The idea of infiltrating built up environments with green spaces has a long history, not only in the remote past, but also in recent thinking and debate on urban planning and architecture. The currently emerging concept of symbiotic nature updates these traditional ideas, introducing new possibilities, technology and management forms. This is a new kind of urban vegetation that offers new opportunities but requires new treatment: new cultivation techniques, new service typologies, new capacity for self-organisation on the part of citizens.

Practicability Symbiotic nature represents a new kind of balance between the natural and artificial components of the urban environment. It responds to a widespread “demand for nature” in all 100 ı SUSTAINABLE EVERYDAY
