Life cycle assessment environmental data for structural steel construction in Greece

The construction industry is a critical sector in relation to sustainable development as its optimisation in terms of the consumption of resources can provide significant environmental benefits. To achieve this, a number of tools and methodologies have been developed to assist decision making. Life cycle assessment is one of the most acknowledged and widely used methodologies to assess the sustainability of construction works. Its efficient use, however, requires environmental data that in some cases are not yet available. Especially for sectors such as steel construction in which the potential for sustainable development is increased due to the recycling and reuse potential of the material, the lack of such data slows sustainability-related progress down. The current research addresses this issue by collecting primary environmental data for cold-formed structural steel and compiling the required data-sets. The data-sets are used to assess the environmental impact of an existing steel building and identify how and to what extent the environment is burdened by its construction. The findings of the research include the aforementioned environmental data which can be used in environmental analyses related to construction projects, while additional conclusions concerning the environmental impact of steel buildings in terms of quantity and type were also drawn.
