BIG has shared details about their latest collaboration with British clothing company Vollebak to design a self-sufficient, off-grid island off the coast of Nova Scotia, Canada. Named after the brand, the 11-acre Vollebak Island is intended to be fully powered by carbon-neutral energy. ... View full entry
A team of students from the University of British Columbia (UBC) has built a near-zero embodied carbon building on campus using hempcrete, wood, and steel as primary materials. — Construction Canada
Called the Third Space Commons, the project was led by Third Quadrant Design, UBC’s first green building design team. The group is comprised of 60 students from the Faculty of Applied Science and the Sauder School of Business. The building is a wooden structure spanning 2,400 square feet, made... View full entry
For many years, industrial hemp was illegal in the US due to hemp’s association with drug use, despite the fact that it does not contain more than 0.3 percent THC [...] Building residential homes with hempcrete was therefore effectively outlawed until 2018, when the Farm Bill distinguished between hemp and cannabis plants. Then, in September 2022, hemp building materials were added to the model US residential building code, paving the way for legal use in 2024. — Reasons to be Cheerful
The International Residential Code (IRC) accepted a modified appendix in September that some are hopeful could be a catalyst for further adaptation throughout the building industry. Builders for Climate Action spokesman Chris Magwood says its greatest potential lies in commercial... View full entry
While most of these buildings are constructed out of more traditional materials like cement, brick, drywall, and plywood, forward-thinking architects and members of the construction industry have increasingly been turning to natural materials as an alternative for the future. Due to its ability to sequester carbon, hemp has landed itself at the forefront of the conversation about natural building. — Topic A
Hemp’s high tensile strength, pliability, and strength-to-weight ratio are increasingly valuable in the manufacture and design of products like fiberboard and even a new concrete alternative. The recent COP26 conference in Glasgow featured the speculative 'Urban Sequoia' design from SOM... View full entry
A project by researchers at Texas A&M University has received a $3.74 million grant for the development of resilient, 3D-printed building designs using a new green material called hempcrete. Its usage has the potential to lower the environmental impact of traditional construction methods and make... View full entry
Turku University of Applied Sciences has received a grant of 70,417 euros to see if hemp could be used more in construction projects.
The research will involve investigating the soundproofing and fireproof properties of the substance.
Researchers will also look at how hemp decomposes and to see how it could be used as fertilizer - in order to determine how eco-friendly hemp's waste materials are.

The article is careful to note that hemp has far less THC than marijuana and is therefore not a psychoactive substance (obviously) – but the news still feels topical. Hemp has been used for centuries for ropes, oils and textiles. But marijuana criminalization efforts in the 20th centuries... View full entry
Hemp Technologies said it wants to use hemp-based materials to construct a 500-square-foot structure at the ruins of Knapp's Castle near Santa Barbara. The principal material for the project is Hempcrete, made of the woody internal stem of the Cannabis sativa plant, which is processed into chips and mixed with a lime-based binder. That concoction is then sprayed on, poured into slabs or formed into blocks like concrete to create the shell of a building. — latimesblogs.latimes.com
