Since the large scale industrialization occurred, the profit oriented human activity has led to a constantly growing environmental degradation. Nowadays, that the actual severity of the problem in hand is impossible to ignore and the spectrum of the future consequences emerges in its full extent, several actions towards the adaptation of sustainability principles in the most problematic sectors of human activity are undertaken. One of these sectors is building sector, incorporating the production, transport, use and replacement of building materials, the use of the building itself (energy consumption for lighting, ventilation, heating and cooling, water consumption etc), the reuse of the building or its materials, the demolition of the building and the disposal of the demolition products. The energy consumed in operating buildings serves as indication of the building sector’s contribution to the total environmental aggravation induced by human activity. According to (OECD, 2003), in the European OECD countries, the building sector consumes the highest amount of energy (40%) in comparison to the transport (22%) and industry sectors (38%). Given the fact that the afore-mentioned quantities include the energy amounts consumed only for the operation of the building, while other processes – unbreakably bonded to construction – such as manufacture and transport of building materials, are not cocalculated, an estimation regarding the impact of the building sector on the environment can be drawn.
