Façade Architectural Glass – Recycled Content

  • Dear eTool Team,

    We receive from the glass supplier for the façade (laminated glass) and from the aluminum frame supplier a self-declarated envinronmental product declaration, according ISO 14021 requirements. I need to change the recycled content parameters separetly for glass and windown in a single glazed window for a project façade, but I’m not finding a way to do it. I looked for an answer in eTool Knowledge Base but can find guidance. Could you help me? This project is using North American LCI v17 database.

    Hi Renato,
    Thanks for reaching out to us.
    I would like to ask for your clarification before completely responding to your query.
    Do you mean that you have received an EPD for laminated glass and an EPD for the aluminium frame? In that case, I would suggest you check both EPDs to see whether the impact of model D (i.e., closed loop recycling (D2), open loop recycling (D3)) has been included. You can create two separate EPDs in eTool for glass and aluminium frame, add them to a design template, delete existing material inputs that already been accounted for in the EPD and add missing impacts where possible.
    In other case, do you mean that you need to change the recycled content parameters separately for glass and aluminium frame in a design template? In this case, I believe you can make change using “Edit material” function. Alternatively, you also can create a custom template based on your specific design specification.
    Let me know if you need further information.

    Hi Alice,
    I meant change the recycled content paremeter separately for glass and aluminum frame in design template. We’ve received and self-declaration (accorging to ISO 14021) specifically about this parameter, and not an EPD. I checked out how to edit the material and it works. Tahnk you!
