The US Hemp Building Association, the American trade association for the promotion of hemp building materials and construction, on Nov. 17 announced an upcoming election and call for candidates of its complete seven-member volunteer board of directors.

Hemp-based construction companies have been knocking on the door of events like San Francisco’s Greenbuild Expo for years. But this year, three companies presented their products and networked with the many designers, builders, architects, engineers and city officials attending.

We spend almost 90% of our time indoors so it’s important to have toxin-free healthy air. Sick Building Syndrome (SBS) is the result of air-tight buildings with poor air circulation.

Hemp-lime insulation from The Hemp Building Company is among the Top 10 finalists in the “Coolest Thing in Colorado” contest, and hemp needs YOUR VOTE online.

This summer I completed hemp spray training held by Cameron McIntosh of Allentown, PA-based Americhanvre, becoming a certified EREASY Spray Application Technician.

Texas workshop participants this fall will get to test a new handcast building method with hemp and Magnesium Oxide, a combination that builds a cement-like wall infill structure that’s stronger than concrete, organizers say. Magnesium Oxide works like lime to create a vapor-permeable wall assembly, one of the advantages of a hemp-based building.

Hemp building materials were officially approved in the model US residential building code at a Louisville, KY public hearing overseen by the International Code Council (ICC) last week.

Burnt, charred wood is historically used as a wood protection measure on the exterior of buildings. It is a technique usually attributed to the Japanese, called Sugi Ban, which we wanted to adapt for hemp construction, by inserting charcoal into the mixture and/or burning the hemp straw itself.

Moisture is one of the biggest problems for buildings as it can rot the structure and bring about mold/other such issues. Most structures fail before their time because of moisture.

Two Israelis living in the south of Alentejo have teamed up with two Palestinians to found an innovative hemp block business for sustainable construction. Its aim is to encourage the local economy with as little ecological footprint as possible and, of course, lots of love. From this unlikely relationship of Israeli-Palestinian friendship, Hemp was born.

We’d like to introduce you to three new hempcrete builds in Texas, Colorado and Michigan. All three projects began, or were completed, in 2022 and the builders/subcontractors are already starting new projects.

A Colorado engineering professor’s 2020 research has given builders and designers a new way to measure the way hemp-based biomaterials can store carbon in buildings. By comparing data from a life cycle assessment of hemp+lime insulation, or hempcrete, using digital tools, builders can easily see the benefits of hemp as compared to traditional construction materials.

One of the biggest motivations in using hemp and lime as a construction material was our interest in building “net zero” or “carbon-negative” or “climate-positive” or “carbon-neutral”– there are a lot of different terms being used, ultimately, it is about achieving a balance between the carbon emitted into the atmosphere, and the carbon removed from it.

A plan from Texas A&M University researchers to 3D print new resilient buildings using hempcrete has the potential to lower the environmental impact of traditional construction methods and make housing more affordable and available.

Sergiy Kovalenkov has built a business in Ukraine and has no intention of ceasing operations during the war. In fact, he feels strongly that this is the time to double down on is efforts to support others in the hemp industry, and to work to move the Ukrainian medical cannabis initiative forward as well.

This article will focus on construction time, practical challenges, reliability and building sciences, between the two options.

I arrived in Bellingham, Washington on the threshold of an unprecedented atmospheric storm which left thousands stranded and thousands more evacuating their homes due to flooding and landslides.

Architect, CEO and designer Monika Brümmer is a biomaterials designer and builder and founder of a hemp brick company based in Granada, Spain.

Researchers from Rensselaer Polytechnic Institute in Troy, NY say they have developed a hemp‐based rebar reinforcing technology for cement construction.

Join Lillian “Lilibet” Clarke as she travels the globe visiting some of the world’s most interesting hempcrete buildings.
