Curtain walling is used just about everywhere else, no reason it can't succeed in housing too. There was a Guardian piece about a hempcrete house just yesterday, with the hempcrete held in frames made from the hemp stalks and resin made from agricultural waste. Started out as a barn, so there was a steel structural frame to be filled in.
The prospect of carbon negative building has to be a huge plus.

- ogrisel 7y agoLime production is carbon intensive (heat + chemical C02 release from the limestone) and the hempcrete curing will take 50 years to fix back the second part. So it can be carbon negative (by fixing the carbon of the hemp itself) but only on the long term (50 years after production) and assuming that the heat used for lime production was from non-fossil source in the first place (which is not the case today: the cement industry typically produces heat by burning natural gas). The heat could be produced from burning green hydrogen (hydrogen produced by water electrolysis using renewable power) but as of today is still too expensive compared to using fossil fuels.
- ogrisel 7y agoA simpler alternative to get carbon negative buildings is to use Cross-Laminated-Timber (CLT) to build both the frame and the walls themselves.
