Prefabricated Facade Panels for Newly Built and Refurbished Nearly Zero Energy Buildings

This paper presents ventilated prefabricated wall panel which utilises recycled construction and demolition waste (CDW) and mineral wool produced using innovative and sustainable technology for reduction of primary energy consumption in building stock. The results of EU Eco-innovation research project titled ECO- SANDWICH represents a significant improvement over the existing prefabricated wall panel products, aligning itself with the mandatory targets of the EU Energy Performance of Buildings Directive - EPBD, its Recast EPBD II. and with Waste Framework Directive targets. The concept incorporates three priorities of the eco-innovation call ; it uses recycled material to create innovative sustainable building product which contributes to greening the business of SMEs through decreasing their environmental impact accompanied by the use of less non-renewable or natural resources, and energy efficiency to Nearly zero energy building (nZEB). ECO-SANDWICH project encourages the re-use and recycling of construction and demolition waste (CDW) in order to shift CDW management from disposal to recycling and reduces utilisation of natural resources. Therefore this way prevents landscape degradation, promotes the substitution of conventional thermal insulation materials by mineral wool produced using innovative and sustainable technology, leading to a reduced environmental impact. It also promotes the implementation of prefabricated, energy efficient products in order to enable reduction of primary energy consumption in residential and commercial buildings and reduce embodied energy, embodied carbon and production of by-product wastes. ECO-SANDWICH is patented as the industrial design product and the name with its visual identity. Amongst major outputs and results of the ECO-SANDWICH project will be a scalable wall panel system that is sustainable and affordable for its end users throughout the life-cycle. The ECO-SANDWICH wall panels will become a recognised construction system used to build a new and reconstruct – modernise existing buildings to a very low energy standard as Passive Houses on a large scale.
