Mjøstårnet成為了挪威最高的塔式木質高層建築
Mjøstårnet in Norway becomes world's tallest timber tower
位於挪威Brumunddal的Voll Arkitekter公司的Mjøstårnet大樓已被高層建築委會和城市人居環境委員會證實為世界上最高的木構建築。
這座高85.4米的高層建築是用交叉型複合木材（CLT）建造的，這是一種可持續使用的新型材料。
繼Vancouver的53米高的Brock Commons Tallwood House後，該建築被命名為世界上最高的木構建築，它是一個木材和混凝土的混合結構。位於挪威Bergen的Treet有49米高，在2019年3月Mjøstårnet完工前曾是最高的全木建築。
Mjøstårnet by Voll Arkitekter in Brumunddal, Norway, has been verified as the world's tallest timber building by the Council on Tall Buildings and Urban Habitat.
The 85.4-metre-high tower was built using cross-laminated timber (CLT), a pioneering material that allows architects to build tall buildings from sustainable wood.
It has taken the title of world's tallest timber building from the 53-metre-high Brock Commons Tallwood House in Vancouver, which has a hybrid wood and concrete structure. Treet in Bergen, Norway, which is 49 metres high, used to be the tallest all timber building until Mjøstårnet completed in March 2019.

這座第三高的Mjøstårnet是由挪威實踐公司Voll Arkitekter為AB Invest設計的。這座18層的多功能建築涵蓋了公寓、酒店、游泳池、辦公和一家餐廳等功能。
木材專家 Moelven Limitre 公司是該工程的木結構承包商，他們設計了由CLT構成的電梯軸，以及由Glulam製成的立柱。Glulam是用木頭製成的，將它們黏在一起作為建築內部的樑柱結構，用來代替混凝土或鋼構件。
Mjøstårnet, the third-tallest building in the country, was designed by Norwegian practice Voll Arkitekter for AB Invest. The 18-storey mixed-use building contains apartments, the Wood Hotel, swimming pool, office space, and a restaurant
Timber specialist Moelven Limitre installed the building's timber structure, including elevator shafts made entirely from CLT, and columns made from glued laminated timber (glulam). Glulam is made from wood that is planed then glued together to form columns or beams, and can be used in the place of concrete or steel elements.

Mjøstårnet在五個施工階段中每階段修建四層。施工時利用一個內部腳手架和一個大型起重機來吊起工廠內預製的結構，在相應的位置進行組裝。
由於Brumunddal是挪威的一個主要林業和木材加工業地區，因此建築所用的材料都是在當地的特色材料。
CLT和Glulam材料吸收了空氣中較多的碳元素，因此它們的強度足以承受較大的荷載。
針對高層木構建築數量不斷增多的情況，高層建築委會和城市人居環境委員會最近修訂了他們關於木構建築的準則。
Mjøstårnet was built four storeys at a time in five construction stages. An internal scaffolding and a large crane was used to hoist the pre-fabricated sections and floor slabs into place.
As Brumunddal is an area of Norway with a major forestry and wood processing industry the materials were sourced locally.
CLT and glulam are strong enough to support large loads, and using timber means the carbon absorbed from the atmosphere by the trees is locked into the structure permanently.
The Council on Tall Buildings and Urban Habitat (CTBUH) recently revised its guidelines to recognise timber as structural material in response to what it described as an "uptick" in the number of tall timber buildings around the world.

隨著城市內的建築密度越來越大，全球範圍內的高層建築數量在持續的增加。CLT作為一種新的可持續材料正在成為越來越多建築師的首選。
Penda設計了一個高層住宅和垂直結構農場的概念性方案，Anders Berensson建築事務所為斯德哥爾摩設計了一個由31座木製摩天大樓組成的城市概念方案。
在英國，建築師們呼籲政府廢除CLT不可做耐燃材料的禁令。因為這種材料不僅比鋼材更環保，而且具有耐燃的性能，同時在燃燒時不會釋放有毒的氣體。

As urban areas grow denser than ever and the number of tall buildings being built globally continues to rise, many architects have turned to CLT and other engineered timbers as a more sustainable building material.
Penda has designed a concept for a residential tower and vertical farm hybrid, and Anders Berensson Architects has developed a proposal for a city of 31 wooden skyscrapers for Stockholm.
In the UK, architects have called upon the government to make CLT exempt from the ban on combustable cladding materials. Not only is the material more environmentally friendly than steel, it also claims to be slow-burning and self-extinguishing without releasing toxic fumes.
