Level(s) uses core sustainability indicators to measure carbon, materials, water, health, comfort and climate change impacts throughout a building’s full life cycle. It is a flexible solution for identifying sustainability hotspots and for future-proofing your project or portfolio. By using Level(s) you are contributing to EU policy goals to strengthen the sustainability of Europe’s buildings, which are responsible for:

  • 1/2 of all extracted materials
  • 1/2 of total energy consumption
  • 1/3 of water consumption
  • 1/3 of waste generation.

Level(s) is open source and freely available to all.
