Twenty first century man spends most of his life in buildings, developing many activities based on his wishes. The design of a building aims to serve these desires by offering the user better comfort, thermal, visual or acoustic conditions, as well as creating a more environmentally friendly operation. By looking at the evolution of buildings over the years, we see their envelope changing form and contributing greatly to energy efficiency. The knowledge, the experience and the parallel technological achievements of the time, give us new possibilities so that we have the means to contribute to limiting the problems occurred.

In today's era, characterized by flexibility, advanced digital technology, innovation and a strong need for environmental protection, efforts are being made for a more flexible and versatile architectural design that responds directly to changing user needs and external environment conditions. Technology, materials and construction techniques are constantly evolving and provide room for more and more design ideas and optimization of building shells through new solutions and building techniques that will contribute both to energy savings and to the overall operation of the building.

The aim of the research is to record and analyze technologies and composite materials that have been introduced in the field of architecture, or are still in research and can substantially contribute to the creation of new design prospects, capable of meeting the needs of users and of saving energy. The subject is investigated by reviewing examples and applications of the above. These examples will highlight the technology of materials used to construct the shell of buildings and the basic structural methodology followed. In addition, the prospects for their development and the various experiments at their level of development will be examined and, finally, new possibilities offered by modern architecture and technology to improve the quality of the environment of a building, both internal and external, will emerge.
