![]() As a result, a majority of landfills are filled with unused concrete and steel from demolished buildings. It’s far more economical for companies to just produce more rather than recycle. Not only is the production of these materials unsustainable, but the chances of them being recycled are low. The chemical and thermal processes involved in producing concrete alone contribute to 8% of global emissions. There are many benefits to using bio-based building materials, especially ecologically. Based on a study done in 2018, on average the production of concrete and other common building materials, makes up about 28% of carbon emissions. Because of this, Glulam provides wooden skyscrapers with the same strength and stability as steel would to a classically built structure. By engineering it in this way it makes the wood extra dense and stronger than normal. Glulam can be produced in different forms, including massive blocks used to make up the main load-bearing portions of the skyscraper. Glulam, short for glue-laminated timber, is comprised of timber bound together with weatherproof adhesive. Everything, including the elevator shaft, features complete wooden construction. Mjostarnet was constructed with 100% different types of engineered wood, produced to be equally as strong as steel. While it’s a tenth of the size of the largest skyscraper in the world – located in Dubai – for a country where the average size of a building is three stories, Mjostarnet is quite the feat. Featuring 18 stories, a hotel, office space, a pool, and a restaurant, the structure is nearly 300 feet tall. This small town is known for its role in the lumber industry, making it the perfect location to build the tallest wooden skyscraper in the world.īuilt with local pine and harvested straight from its backyard, Mjostarnet is the pinnacle of lumber-based architecture. The building, known as Mjøstårnet – meaning tower of Mjosa – is located in Brumunddal, a small industrial Norwegian town that sits on the edge of Lake Mjosa. Norway’s third tallest skyscraper also has the most unique construction: it’s made completely out of wood. It is crucial to use these trees and replant them after harvesting to encourage sustainability of forests," the company said.Mjøstårnet: the tallest wooden skyscraper in the world. "Although the large amounts of Japanese cedar and Japanese cypress planted after the Second World War have now reached the time for harvesting, they are being left in an un-maintained state as devastation of our domestic forests continues. However, the self-supply rate for domestically-produced timber is only at around 30 percent, the company states, and Japan's forests are at risk due to insufficient maintenance. This puts it at second place among OECD member countries, behind Finland. The company notes that forests cover approximately two thirds (68.5 percent) of Japan's land area. Sumitomo Forestry can trace its origins in the timber industry back to 1691 and the W350 building is planned to mark the company's 350th anniversary in 2041. The institute is looking at the "expanding possibilities for wooden buildings as a road map for future technology, such as the development of building methods, environmentally-friendly technologies, and trees that become resources and building materials," the company said. The concept for the building has been prepared primarily at Tsukuba Research Institute, Sumitomo Forestry's research and development facility. ![]() Sumitomo Forestry said it would "make every effort to further enhance fire and seismic resistance." Wooden cities With earthquakes not unusual in Japan, the building will incorporate a structural system composed of braced tubes made from columns, beams and braces "to prevent deformation of the building due to lateral forces such as earthquakes or wind."īeing a timber building, the risk of fire would seem an obvious concern, but the material's sensitivity to moisture (and potential for warping and distortion) is also a consideration. The building plans show balconies that continue around all four sides of the building, giving a space "in which people can enjoy fresh outside air, rich natural elements and sunshine filtering through foliage." Greenery will feature heavily in the building from Sumitomo Forestry with foliage connecting from the ground to top floors offering "a view of biodiversity in an urban setting." Currently the tallest wooden building is 18-storeys high (53 meters) and serves as accommodation for students at the University of British Colombia.
