Green architecture has experienced resurgence in the sixties and seventies of the twentieth century as a result of the growing awareness of the need for preservation of the environment. Short-term economic shocks and the newly created movements for environmental protection may have been initiators of the new trend, but it survived the very same context in which it has emerged. The advantages of sustainable architecture have quickly been identified and grounded as the standard for the years to come. Ecological aspects of architecture i.e. building, were usually not taken care of, but now they become a key issue. Badly designed buildings drain natural resources and destroy the environment. In an era of rising energy prices and degradation of natural resources, the need for sustainable architecture is becoming a necessity, and the use of ecological materials an imperative. As such, it carries a number of challenges. During the construction of buildings that are called "green", the choice of materials is significantly limited, the prices are often very high and the technology is still new and insufficiently explored. Sustainability and the environmental aspect of green architecture are not sufficient reasons for it to be accepted by the public. It speaks in favor of inglorious epilogue of the solar architecture from the seventies, which despite its sustainability and environmental enlightenment has never been accepted by the wider public. Many say that the main reason is that it gives emphasis on function, but not on the form. It is expected from the green architecture of the twenty-first century to combine these two categories and therefore to present the innovation - both in terms of function and form. The subject of this paper is the form of the object that is created and "read", which derives from the context and specific conditions on the ground location where the facility is built. The context is understood in its broadest possible sense. It includes the existing forms of in space and time, and historical and cultural heritage.
