Metal manufactures were the subject of study of the inquiring subject, as well as their possibility of corresponding to the requirements of bioclimatic planning.

 Studying the history of metal manufactures in the passage of time, characteristic examples of buildings that played decisive role in their course of development are cited, so as their special characteristics.In this context, there is a reference to modern examples of metal manufactures in world level, including Greece.

 The study then focus, on the basic elements that compose a metal manufacture, marking the special techniques of treatment and layout that is required for its main parts. Metals are categorized according to their importance and use in manufacture.More specifically, an extensive analysis and comparison of attributes of metals is performed, presenting also ways of handling their certain particularities that concern the viability and energy behavior of manufacture.

 Concluding, the study concentrates on the comparison of a metal building, and its variants, with a conventional concrete manufacture consisting of the same data. There is an attempt to determine whether these metal manufactures can compare to traditional manufactures when it comes to energy efficiency. This is a key area for the future and their extended usage, in times where environmental protection and energy efficiency are a global concern, is becoming increasingly imminent.
