Solution Information

Solution Title

Recycled and Natural Materials and Products to develop nearly zero energy buildings with low carbon

Solution Title (in English)


Resource conservation, waste reduction, energy saving


Europe, building industry


The objective of the LIFE ReNaturalNZEB project is to demonstrate and promote solutions for nearly zero energy buildings an EU construction standard requiring exceptionally high energy performance. Ten new constructions and renovations in Spain and Portugal will cut their carbon footprint and building costs by replacing heavy building materials with environmentally sustainable alternatives. Project partners will adopt green criteria and circular economy approaches in sourcing these components from natural and recycled materials that weigh on average half as much as their industrial counterparts. The substitution is expected to reduce energy demand in buildings by up to 80% supporting targets set out in the Energy Efficiency Directive and the Energy Performance of Buildings Directive. The project will organise dozens of face-to-face events and produce construction guidelines to raise awareness among building sector professionals and the general public of the environmental and financial benefits that zero energy buildings have to offer.
