The relationship between architecture and technology is an important part of the creative progress. An example of this was the Russian construct ivists' architecture for a cultural revolution: Melnikov's 'solar pavilion' and 'sleeping quarters' for his 'green city'. The following projects represent the present state of the art. The first is at Nimes, France (Neinansus 1, Nouvel & Ibos). The second is located in Stuttgart, West-Germany (Hysolar, Behnisch & Partners). LOG ID in Ttibingen designed a public library in Herten, West - Germany promoting further development of solar architecture. The last example describes the special implementation of space research technology by the British group 'Future Systems'.
