ENDPOINT-BASED LCA EVALUATION OF FLOOR CONSTRUCTION
Abstract
Current environmental problems, which are resulting from the construction in building sector require instrument to help with reducing resource consumption and environment pollution. Life cycle Assessment (LCA) is of the building sector popularly used tool to quantify the environmental impacts. There is a large number of impact assessment methods for quantification of environmental impacts in life cycle. LCA approach can be directly applied to the building sector. However, buildings are exceptional products and have many characteristics that serve to complicate or frustrate the application of standard LCA methods. This paper presents an evaluation of a floor construction in family house using two LCA methods. The results of the environmental impacts calculated by IMPACT 2002+ and Eco-indicator 99 methods were compared using the functional unit 1m2 of the floor layer. Impact categories were calculated using the software SimaPro and applying the Ecoinvent database. The results obtained were compared in the endpoint categories Human Health, Ecosystem Quality and Resources. Concrete block and the Portland cement were confirmed to have the highest negative impact regarding the Human Health and the Ecosystem Quality while polystyrene in the Resources.
