The definition of sustainable development „to meet the needs of the present without compromising the ability of future generations to meet their own needs” is attributed to architecture, too. Bioclimatic architecture is the golden mean between the notions of energy effectiveness and sustainability. Its aim is to create an environment suitable for the nature and humans using local resources, natural and climatic conditions at the same time decreasing the need for artificial ways of microclimatic regulation. Sources of inspiration may be found both in the synthesis of different scientific branches and experience accumulated in traditional building. However, copying regional forms is a controversial matter: it is hard to apply traditional building aesthetics in modern building types, e.g. office buildings where high-tech solutions have been employed. The idea of sustainability is interpreted in terms of using traditional materials and building methods (low-tech), at one end, and, an accentuation of most modern technologies in architecture (eco-tech), at the other. Initially it seems impossible to see common characteristics of a ‘low-tech’ house and a glazed ‘eco-tech’ highrise in the middle of a city, yet they have something in common: evaluation of their climatic conditions since the very start of the concept. From this starting point it is possible to reach differentiated visual results, however, at the end we arrive at a building adapted to regional environment and climate and functioning best only in one particular place.
