In nature, plant structures adapt intelligently to their environment, and these principles are now also being utilised in architecture. Researchers at the Universities of Freiburg and Stuttgart have developed the “Solar Gate”, a fa\u00e7ade system that reacts to changes in humidity and temperature without the need for mechanical or electrical components.<\/p>\n\n\n\n\n\n
This adaptive shading system was installed on the livMatS Biomimetic Shell, a research building at the University of Freiburg. It is based on hygromorphic materials that open and close independently like pine cones. As a result, the system lets sunlight into the building in winter for natural heating and protects against excessive heat in summer – completely energy self-sufficient.<\/p>\n\n\n\n\n\n
4D printing enables intelligent fa\u00e7ades The elements produced using 4D printing curl up and open in high humidity, while they flatten and close in dry conditions. The “Solar Gate” thus offers a completely new way of regulating buildings in a climate-neutral way.<\/p>\n\n\n\n\n\n Energy-efficient construction of the future With this innovative shading system, the researchers prove that sustainable construction methods can not only be environmentally friendly, but also efficient and cost-effective. The future of architecture could therefore be a great deal closer to nature.<\/p>\n\n","protected":false},"excerpt":{"rendered":" A research team from the universities of Freiburg and Stuttgart has developed an innovative fa\u00e7ade system that adapts automatically to changes in the weather without the need for energy.

<\/strong>The secret behind the innovation lies in the combination of bio-based cellulose materials and state-of-the-art 4D printing technology. Cellulose, a renewable and abundant raw material, reacts to fluctuations in humidity by expanding or contracting. The research team has utilised this natural property to develop a two-layer structure that automatically adapts depending on the weather.<\/p>\n\n\n\n\n\n
<\/strong>The building sector is responsible for a large proportion of global CO\u2082 emissions. Buildings can significantly reduce their energy consumption for heating, cooling and ventilation using intelligent, bio-based materials. The “Solar Gate” shows how natural principles and modern manufacturing technologies can lead to sustainable architectural solutions.<\/p>\n\n\n\n\n\n
