Architecture’s tension towards the ecological and economical constructions during the last few years sets new targets in the hull planning (passive architecture) as well as in the planning of the systems that are being used (active architecture).
The study of the placement, the way of building’s construction, the technical obstacles (neighboring buildings), the geophysical and physical elements ( ground, trees, sun, wind ) sets the targets and the limitations on the design.
Technical methods attribute the necessary levels of lighting and heating to the space covering in this way all the human needs for visual and thermic comfort.
