Sustainable Construction

Sustainable construction aims at limiting buildings' environmental impact, improving at the same time quality when it comes to aesthetics, viability, resistance and durability. Sustainable construction techniques can be implemented throughout a building's life, from the selection of initial materials up to its demolition and material recycling.

Sustainable construction involves in particular:
  • Using recyclable materials aiming at preserving natural resources;
  • Integrating renewable energy sources into building designing;
  • Optimising renewable energy sources.
