Abstract

This paper aims to analyze the impact of recycled materials on energy reduction and clean energy transition of buildings. The life cycle energy of building using virgin materials is compared with that of building using recycled materials, and the energy savings due to recycled materials is calculated. Also, the impact of recycled materials on clean energy transition is verified by calculating the module area of the photovoltaic panel achieving the same amount of energy savings. As results of a case study, replacing virgin to recycled materials reduced 10% of life cycle energy. It means that the use of recycled materials can reduce 10% of module area of PV system for achieving clean energy transition. Recycled materials should be considered for fundamental energy reduction and effective clean energy transition.

Keywords recycled material, life cycle assessment, life cycle energy, clean energy transition
