Produce plant wooden building products and standard houses
The Moso species native to China stores up to tonnes of carbon per hectare — comparable to trees, but much more cost effective. Bamboo is also a pioneer plant, meaning it can grow in places no other plants can. This makes it a valuable tool for re-stabilising eroded landscapes, and also means that it does not have to compete with food crops for suitable land. And it is strong. So strong that some researchers believe bamboo composites could one day replace steel as the structural reinforcement material of choice in buildings — a shift that would drastically reduce the carbon debt of the construction industry.

The Romans have been using it since the days of Julius Caesar, but not to get high. Both Washington and Jefferson grew it. Now that several states have legalized the use of marijuana for some recreational and medical purposes, one of the biggest untapped markets for the cannabis plant itself — at least one variety — could be as a building tool.
Hemp structures date to Roman times. A hemp mortar bridge was constructed back in the 6th century, when France was still Gaul. Now a wave of builders and botanists are working to renew this market. No pests, no mold, good acoustics, low humidity, no pesticide. It grows from seed to harvest in about four months. A strain of the ubiquitous Cannabis sativa, the slender hemp plant is truly weedlike in its ability to flourish in a wide variety of climates, growing as high as 15 feet and nearly an inch in diameter.
This is the source of the tough fiber, which can be used for rope, sails and paper. Hemp is typically planted in March and May in northern climes, or between September and November below the Equator. Those dried fibers are then blended for a variety of uses, such as adding lime. This creates block-like bricks known as hempcrete.
Industrial hemp contains a mere 0. The cannabis present at a reggae fest, for instance, contains as much as 20 percent. The two strains look different, too. The rule goes: the better the budding flower, the poorer the hemp.
Getting a mature plant in just a few months — with less fertilizer than needed for industrial crops like corn, and without chemical fertilizers or bug sprays — makes the potential for profit huge.
As hemp taps water underground, its long roots circulate air, which improves soil quality — another boon for farmers looking to rotate crops. The plant is still highly regulated. This January, though, California legalized use of the plant in full. Still, in the United States special permits are needed to build with hemp, and the requirements can vary by county and state. The first modern hemp house was constructed in , in North Carolina. There are now about 50 such homes in the country. But not much hemp is grown here; a little less than 10, acres so far, enough for about 5, single-family homes.
Roughly 30 nations now produce hemp, including Spain, Austria, Russia and Australia. Hundreds of buildings across the continent use the substance as insulation to fill walls and roofs, and under floors in wood-framed buildings. Its promoters also boast that it has a lower carbon footprint, requiring three times less heat to create than standard limestone concrete.
Lime plaster coatings or magnesium oxide boards have to be applied to anything touching hempcrete, or the lime will calcify it and lose its ability to absorb and release water. While that sounds like a lot of work, Ms.
Beckerman pointed to the long-term payoff. ASTM International , a technical standards organization, formed a committee to address this in Nonetheless, the use of hempcrete is spreading.
A Washington State company is retrofitting homes with it. Left Hand Hemp in Denver completed the first permitted structure in Colorado last year. One major issue is cultivation. Although it has been legal to grow hemp in Canada since , farmers need to apply for licenses. In Australia, industrial hemp agriculture has been legal for over 20 years. Farmers and researchers in more than a dozen states can now import hemp seeds. The Industrial Hemp Farming Act , pending in the House for the seventh time, would exempt hemp plants in toto from the controlled substance designation, an Olympic leap toward a burgeoning agro-business.
Sergiy Kovalenkov, 33, a Ukrainian civil engineer who spent the last three years building hemp structures and consulting on projects in Ukraine, France, Sweden and Jamaica, is beginning a project in California. The hardest steps, Mr. Kovalenkov said, are paperwork, permits and seeds. It has to come from California. Only one facility in the United States processes hemp stalks, in North Carolina. Kovalenkov said.
Kovalenkov said, laughing. You cannot smell cannabis — it has nothing to do with smoking weed or cannabis plants. Hempcrete by itself is just an insulation. Mead, the head of Hempitecture, echoes the concerns of others. For farmers to expand, he said, the infrastructure has to be there. But what does a hemp house smell like?
Is ‘Hempcrete’ Becoming a Viable Foundation Material?
Every building material comes with an environmental cost of some sort. However, some principles can help guide your choice of sustainable materials and construction systems. Careful analysis and selection of materials and the way they are combined can yield significant improvements in the comfort and cost effectiveness of your home, and greatly reduce its life cycle environmental impact. The first step in any strategy to use sustainable materials is to reduce the demand for new materials.

Today the leading construction companies are working ever harder to create as ecological living space as possible for people and so use of more ecological, natural building materials in construction is rising. Wood is one of the few materials whose extensive use in construction makes the dwelling not only safer for the inhabitants of the house but has a positive impact on the ecosystem of our planet globally. Comfortable living space, environmental considerations and availability of the material are reasons why people choose to build timber houses.

Wood is a fundamental part of construction. It is a versatile construction material because it can be found everywhere. Early settlers in North America used wood to build log cabins since it was more efficient than transporting other materials all the way from Europe. Rosmanitz, Wood did not require extensive tools in order to be produced as a construction material.
Low-rise residential buildings include the smallest buildings produced in large quantities. Other examples include the urban row house and walk-up apartment buildings. Typically these forms have relatively low unit costs because of the limited purchasing power of their owners. The demand for this type of housing has a wide geographic distribution, and therefore most are built by small local contractors using relatively few large machines mostly for earth moving and large amounts of manual labour at the building site. The demand for these buildings can have large local variations from year to year, and small builders can absorb these economic swings better than large organizations. The building systems developed for this market reflect its emphasis on manual labour and its low unit costs.

This chapter provides information related to commonly used wood construction methods i. It briefly discusses the manufacturing of four major lumber-based mass timber products i. The discussion also addresses primary lumber products, such as dimension lumber, machine stress-rated lumber, and finger-joined lumber, which are the building blocks from which mass timber products are manufactured. Advantages of using wood in construction are illustrated by examples largely from North American practices.
