Building Life Cycle Assessment (LCA) is a tool for calculating and examining the environmental impact of a building at all stages of its life span. This covers all processes from the production of raw materials to the construction and use of the building until demolition.
The life cycle assessment performed in accordance with ISO 14040 standards aims at determining the cumulative environmental impact of the building. Sustainable buildings with reduced negative impact on the environment shall be designed as the architectural and engineering measures required to minimize environmental impact are taken.
Following the improved design, environmental performances will be compared and changes in ten basic environmental impact fields including carbon, energy and water footprints, acidification, land ecotoxicity and such will be detailed.
Another important outcome of Life Cycle Assessment (LCA) is the analysis of how much difference can be made by better design and in what way.
The analyses, evaluation and improvement studies performed under Life Cycle Assessment (LCA) are a significant input for the corporate sustainability policies of a project’s stakeholders and provide higher points and titles for the building on international green building evaluation systems including LEED and BREEAM.
