Dynamic Life Cycle Assessment of a Double Glazing Bay

The aim of this research is to optimize a methodology used in eco-design, that so-called Life Cycle Assessment (LCA), in order to increase its representativeness when evaluating systems. This optimization consists of introducing temporal factors in the environmental impact assessment. This process is called Dynamic Life Cycle Assessment (DLCA). It uses the Enhanced Structural Path Analysis (ESPA) method combined with OpenLCA software and an algorithm written under MATLAB. Then, the Life Cycle of the Inventory (LCI), carrying out the inventory of input and output masses of the controlled compounds (NOx, O3, PM10, etc.) for relevant studied subsystems, takes the date of the process into account and breaks the amount of pollutants flows down. A double glazing bay was chosen to apply this method.
