Thanks again Will for your interest in my writings.
Not sure what building forecasts you mean?
I hope I covered by references.
But this UNEP (2020) report may help https://globalabc.org/sites/default/files/inline-files/2020%20Buildings%20GSR_FULL%20REPORT.pdf
Also I referred to this large IPCC Report, especially its refs to buildings https://www.ipcc.ch/sr15/download/
Plus UN Emissions Gap report 2020 https://www.unep.org/emissions-gap-report-2020
There are also some diagrams on p.24 of article (within Italian part).
Please let me know if this is not what you are seeking, happy to oblige.
BTW, I am STILL pursuing project with Green Bldg Council of Australia and Arup to change rating system to acknowledge embodied carbon and the SIZE of buildings, as we discussed some time ago. Have produced draft report, more to be done. But will certainly keep you in mind.
Look forward much to keep in contact.
Best regards
David
