[edit] Identify a significant future challenge

Although the third millennium has offered numerous merits and advantages for human life, it has also led to the development of bigger and more complicated problems such as the followings:

• Shrinking number of family members within each family and the enhancement of the number of families living in cities.
• Increased number of homelessness which is due to the growth of slums where there are not enough educational, health and public facilities and services.
• Increased crime rate which is attributed to the lack of appropriate infrastructures.
• Increased environmental pollution and climatic changes
• Dispersion of urban centers and traffic congestion
• Shortage of energy resources and fossil fuels due to increased consumption.

In addition, it is estimated in the year 2030, the total population of the world will reach five billion people and two third of them will live in cities. The enhancement of population and the rapid growth of urbanization is changing cities into mega-cities and giga-cities. That is, it can be argued that, in 2030, over forty million people will live in mega-cities and over 170 million people will live in giga-cities.

[edit] Offer a design solution

For offer a design solution for how that challenge could be tackled in today's buildings, I propose “responsive architecture and designing flexible buildings.” Responsive architecture, interactive architecture or dynamic architecture is about changeable, moving and animated buildings, and their shape changes in order to adapt to the requirements of the design. This type an architecture with the ability to change, move, animate or rotate allows you to fulfill the demands that were previously not dwelling architecture and non-flexible.

Buildings are fabricated in this type of architecture are constantly changing. This new approach is a kind of competition with the current methods of contemporary architecture, which, with the help of advanced technology and artificial intelligence, is capable of interacting with and responding to human needs. Responsive architecture, interactive architecture or dynamic architecture, is a new approach that is expected to change the future architecture, the city's shape and the quality of life in cities, and through it, the buildings will give a fourth dimension called Time. In this thinking, the buildings will not have rigid and fixed shapes Which consequently shaped city will change continual.

In this type of architecture, we can construct smart building with using computers and Advance technologies in the field of building engineering. An achievement that can lead to the realization of an architecture that meets human needs in a variety of fields.
