The sustainable prefabricated wall panel system made of he sustainable prefabricated wall panel system made of recycled aggregates

The sustainability assessment of a building must represent a part of an integrated evaluation of the building performance. The envelope is one of the main parts of the buildings and external walls directly influence its thermal and environmental performance because of their considerable weight in the initial embodied energy, life-cycle energy consumption and whole-life cost. Additionally, the amounts of construction and demolition wastes generation soar each year and the supply of natural aggregates is contributing considerably to landscape degradation. Therefore, this paper presents the life cycle analysis of an innovative ventilated prefabricated concrete wall panel with integrated mineral wool insulation allowing very low energy design and retrofit of buildings. Implementation of prefabricated, sustainable products will enable reduction of environmental impact of residential and commercial buildings The purpose of the research is the encouragement of the re-use and recycling of construction and demolition waste (CDW) in order to shift CDW management from disposal to recycling and reduce utilisation of natural resources thus preventing landscape degradation. The substitution of conventional thermal insulation materials by Ecose® based mineral wool produced using innovative and sustainable technology is leading to reduced environmental impact through the reduction of embodied energy, embodied carbon and production of by-product wastes.
