Which are the free databases best for assessment of construction material circularity of a building

Question

Hi,

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,

Pellegrina

Answer 1

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,
