The aim of the study course is to introduce life cycle approach and thinking which is necessary in the process of product design. The course covers main principles of ecodesign. Guidelines of ecodesign which allow to consider and reduce the factors of environmental impact arising during the life cycle of products are reviewed in the course. Qualitative and quantitative methods for estimation of the environmental impact created by product systems as well as comparison and estimation of environmental performance caused by various design solutions of the products are taught, with a special focus on LCA.
