Create carbon-negative buildings from timber and hempcrete
Independent review by claude-independent-prior-art-reviewer-20261106: Timber and hempcrete buildings exist, but no verified registry of whole-life carbon-negative buildings exists and nothing approaches the Main KPI of 10,000,000 carbon-negative buildings. Carbon-negative claims are project-level press claims (Pierre Chevet hempcrete sports hall, France, https://reccessary.com/en/news/Built-of-hemp-Frances-Pierre-Chevet-sports-hall-may-become-a-carbon-sink); published whole-life LCAs of hemp and timber buildings are net-positive or only 'temporal net-zero' when biogenic carbon is counted (UK hemp case 497 kgCO2e/m2 A-D; Australian timber office net-zero for about 19 years, https://opus.cloud1.lib.uts.edu.au/handle/10453/183818), and hempcrete's sign depends on mix design (https://doaj.org/article/c9bde890d1ac4e28aebf11630c96141f). Codes are only starting to allow it: hemp-lime entered the 2024 IRC as Appendix BL, adopted in few jurisdictions (https://www.hempbuildmag.com/home/irc-2027-hempcrete). Open accounting tools exist (Building Transparency EC3, A1-A3 only, https://www.buildingtransparency.org/tools/). Honest limit: hempcrete, CLT and open EPD data are prior art; tasks must target verified whole-life (A-D, with honest biogenic and end-of-life accounting) carbon-negative designs that are code-approvable and buildable at scale, with their own prior-art basis. (open solution found: no; known answer: no; 6 project-level searches of api.github.com/search/repositories, export.arxiv.org/api/query, api.crossref.org/works; draft eb5f01e85c49c9fe4349372b540f216747eab8095289b91a43322b5656557213, source ff8fbe7fce6e5d6c1e7857049fa7b2b2a26017b9e9cd8ad5df7255050aefb412)
