![]() Besides this, it also includes a ground floor restaurant, meeting rooms on the second level, offices on the third through seventh floors, 33 apartments spread across the upper six floors, plus an event venue on the 17th floor, and a terrace on the 18th. The approximately 11,300-square-meter tower houses a wide mix of uses, most prominently the appropriately named Wood Hotel, with 72 rooms on floors eight to 11. ![]() The adjoining low rise portion of the complex is a CLT structure. Sustainable forestry, practiced by engineered wood producers, results in planting of replacement trees that further the virtuous circle of carbon sequestration.įor Mjøstårnet, the primary tower structure consists of a glulam frame with CLT used for secondary elements such as the elevator core and stairways. Trees absorb carbon dioxide (CO2) and as such a timber building, by preserving wood, keeps carbon out of the atmosphere that would be released if a tree decomposes. Steel and concrete building construction is a major source of greenhouse gas emissions, whereas tall timber buildings have a much smaller carbon footprint and can be carbon neutral or even carbon negative over the long term. And while beauty is in the eye of the beholder, wood is widely considered an attractive material that can connect the built and natural environments.īut, probably the biggest advantage of engineered wood is environmental. This allows for faster and safer building site conditions. In certain ways, engineered wood is superior to structural steel and concrete, in that it is much lighter and more conducive to modular construction. In contrast, glulam consists of several layers of wood with grains running parallel glued together to form columns and beams.īoth CLT and glulam compare favorably to steel and concrete in terms of their strength and fire resistance. Layers of kiln-dried wood are pressed together with adhesives, with the grain of adjoining pieces at perpendicular angles, creating structural panel walls and flooring. Instead, it uses “engineered wood,” a refined product of which the two main variants are cross-laminated timber, abbreviated CLT, and glued laminated timber, which is sometimes called GLT but more commonly known as glulam. Mjøstårnet’s primary load bearing structure consists entirely of timber, but not the lumber used in log cabins and conventional wood frame houses. The skyscraper’s wooden facade can be seen for miles around, but what makes it unique is what’s inside. The 85.4-meter (280-foot) tall Mjøstårnet (Mjøsa Tower) is located in Brumunddal, a town with a population of about 10,000, along the E6 highway linking Oslo with Lillehammer. Near the shore of Mjøsa, Norway’s largest lake, stands the world’s tallest wooden building amidst a region more known for farms and forests than high rises.
