Sorry we haven’t got back to you earlier. The summaries at the structure and project level are actually reporting the results of the “favourite” design only. Your post has raised a very good point, the way we’ve implemented this is not intuitive, we’ll put a feature into our software development backlog to deal with this.
Unfortunately there’s no easy workaround at this point. Most reports etc are really targeted at he design level and comparing designs. A feature we have coming up is neighbourhood level LCAs which will enable quantification of multiple structures (the designs just being design options for that structure) and we also hope to add a carbon calculator for occupant transport, food and waste. The above feature you’ve generated will be delivered with this, and we’ll also introduce reporting at the project level that should suit your requirements well. Please get in touch if you want an interim solution and we’ll discuss how we can resolve this.
