I would like to know which free databases are the best for the assessment of the construction material circularity of a building in the United Kingdom (UK)?

Some data that I need from the database are steel beams & columns, concrete slabs, windows, sheathing board (Gypsum and Oriented Strand Board).

I can see the following free databases on the website of Nexus OpenLCA that I can download and use within OpenLCA:

  1. IMPACT World
  2. Environmental Footprints
  3. OzLCI2019
  4. exiobase
  5. ARVI
  6. Agribalyse
  7. NEEDS
  8. ELCD
  9. BioenergieDAT
  10. OpenLCA LCIA Methods

Best regards,

Dear Pellegrina,

In my opinion, you should take various free databases to model your building as the free databases are not so complete.

I advise you to begin with (in order of preference): 

  1. Environmental Footprints
  2. NEEDS
  3. ELCD
Have a nice LCA,
