Local building departments may also demand an engineer\u2019s stamp on hempcrete house plans because the material is considered unproven here. These steps can be streamlined or eliminated with hemp in the IRC, supporters say. <\/p>\n Click here to go to our FREE online community.<\/strong><\/a>\ufeff<\/strong><\/p>\n The US Hemp Building Association raised more than $50,000 and worked countless hours with a committee of experts<\/span><\/a> in construction codes, engineering and hempcrete building to submit hempcrete<\/span><\/a> for certification in January. Over six months, a writing team and engineering consultants wrote the submission document with input from\u00a0 \u201cfour civil or structural engineers, four architects, 15 hemp-lime builders, six industry representatives, an academic researcher, an energy expert, and two code experts,\u201d Waddell said in a statement.\u00a0<\/p>\n Straw bale builders in the 1990s paved the way for US natural building materials to be included in the US residential housing codes<\/span><\/a> as part of a series of appendices to the code, which was last updated in 2018. Codes are updated every few years and it was important to submit hempcrete as soon as possible.<\/p>\n \u201cIn the first code cycle, after the legalization of hemp, we are now in the model codes for the US,\u201d Waddell said.\u00a0<\/p>\n ICC committee voters work for government agencies protecting the public\u2019s health and safety and \u201chave no financial stake in the outcome,\u201d according to the organization.\u00a0<\/p>\n The final step before new codes are published including hempcrete will be a final public hearing in Louisville KY in September.\u00a0<\/p>\n \u201cWe are very excited about this historic opportunity to make a giant stride for hemp-lime construction in the US,\u201d Waddell said.<\/p>\n Jean Lotus is editor\/publisher of HempBuild Magazine<\/em><\/p>\n (To find out more about advertising CLICK HERE<\/a>).<\/p>\n Training and Education<\/strong><\/p>\n Online Hempcrete Masterclass from Endeavour Centre<\/strong><\/a><\/p>\n<\/li>\n<\/ul>\n Publications<\/strong><\/p>\n Hemp Building Directory 2022 – Guide to the International Hemp Building Industry<\/strong><\/a><\/p>\n<\/li>\n Available Now! \u201cHemp Buildings – 50 International Case Studies\u201d by Steve Allin<\/strong><\/a><\/p>\n<\/li>\n<\/ul>\n Hemp Hurd (shivs)\/Hemp Fiber\/ Hemp Microfiber<\/strong><\/p>\n Hemp Building Company: Hempcrete Supplies, Training Programs.
