I would like to vary the recycled content of steel in the main structural steel frame templates (Framing structural steel (universal beam column etc) kg) in the BRE dataset, but I can’t find any reference to recycled steel content or the ability to alter it. Please can you advise?
Unfortunately you’ll have very limited options if you’re using the BRE IMPACT dataset so you probably won’t be able to do what you’re suggesting here. Fortunately, we’re currently in the process of getting our AusLCI/EcoInvent dataset accepted by BRE which will open up a whole lot more material options for our UK users in, hopefully, the near future.
