Refurbishment of Decommissioned Buildings in the Context of Sustainable Development

摘要

At present, it is considered that about 50% of the raw materials existing on the earth are used to raise buildings. Buildings consume approximately 40% of the total energy in the world, and are responsible for 35% of the overall CO2 emissions as well as for 50% of the total amount of waste. It is for this reason that any intervention brought to the built space by sustainable development projects, in general, and to decommissioned buildings, especially, will have a positive impact upon further energy consumption, waste production and CO2 emissions. From the perspective of the last decade, the concept of sustainable development has reached that level of strategic concern that is found worldwide. From the viewpoint of constructions, sustainable development require a careful re-examination process of architectural concepts, the implementation of new technologies that make use of green materials and of solutions that respond to the exigencies that could “meet the needs of the present while not compromising the changes of the future generations to meet their own needs” (http://ro.wikipedia.org/wiki/Raport_Brundtland).
