Sara Kulturhus by White Arkitekter Is a Wooden Wonder

在最近的一个report on embodied carbon from the Rocky Mountain Institute作者指出，“将木材作为一种碳排序的材料是行业专家之间的争论。”他们说，在瑞典，“握住我的（啤酒）”，当他们用最精致的木材技术建造高大，华丽的建筑物，并说“木材是过渡到Net Zero的基石”。

这样的建筑是上图所示的萨拉·库尔胡斯文化中心。建筑师，白色Arkitekter，描述了：

"Standing almost 80 meters [262 feet] tall, Sara Kulturhus is one of the world’s tallest timber buildings at inauguration in September 2021. It houses six theatre stages, the City Library, two art galleries, and a 200-room hotel with conference centre, restaurants, and spa. The 20-storey hotel offers dramatic views that stretch for miles over Skellefteå, located just below the Arctic Circle in Sweden."

Skellefteå is a mining town, but also had a traditional timber industry and a history of wooden buildings, most of which were demolished and replaced with brick.

"With Sara Kulturhus, this tradition has been revived. Combining the timber tradition with modern technology and the local heritage, the project is realized with a structure entirely made of timber. Timber from the region’s sustainable forests located approximately 200 km [124 miles] from the building and processed in a sawmill 50 km [31 miles] from it."

确实，现代技术。该建筑物是您可以用木材做些什么的演示项目。这些屋顶桁架是如此戏剧性，大块的压缩成员会粘住。

Wood panels on the walls both absorb sound and bounce it in different directions; the acoustics are probably wonderful. "The project aims to broaden the possible applications of timber as a structure material for complex and high-rise buildings, sparking advancement in sustainable construction. The very diverse programme has called for a range of innovative solutions in mass timber construction to handle spans, flexibility, acoustics, and overall statics."

The hotel tower is built of prefabricated modules made of Cross-Laminated Timber (CLT) stacked high between elevator and stair cores made of CLT. "Integrated structural design has eliminated the need for concrete entirely from the load-bearing structure, speeding up construction and drastically reducing the carbon footprint."

Digging into White's2030年的路线图：我们的气候阳性未来的策略，one realizes that green sustainable building is about a lot more than just building with wood; they get the principles that have been discussed by theWorld Green Building Counciland are mentioned in the RMI report. Here's a long quote from a document that is worth reading:

"The starting point is to use what has already been built or produced and, based on what already exists, to create new designs, functions, and attractive beplay体育官网电脑environments. Materials are used efficiently in nontoxic circular flows and construction can be dismantled so that the material can be returned to the material flow.

The architecture we create must stand the test of time and be timeless. beplay体育官网电脑Environments and buildings are designed so that they evolve over time with general and flexible floor plans and construction that make efficient use of the area. Offices can be converted into homes, streets can become parks, and ground floors can become social meeting places.

建筑物是气候中性或气候阳性的，这意味着它们在生命周期期间不会导致负温室气体的负面气体，甚至可能捕获二氧化碳。新的结构主要是使用木材和生物基材料或使用低碳足迹的回收原材料进行的。”

As the road map notes, building with timber is only one part of a larger picture of sustainable design. The issue of the carbon footprint of mass timber construction is controversial on both sides of the Atlantic, although the issue of its beauty isn't, nor its contribution to the gorgeousness of the Sara Kulturhus and the warmth of the wood—so much biophilia that I feel more relaxed just looking at it. It's truly "a showcase for sustainable design and construction where all forms of culture live side-by-side."

As White Architekter concludes, everyone in the industry should be doing this.

"In the climate-positive future, the construction industry considers the long-term lifecycle perspective and investments in quality, sustainability, and timeless architecture to be a matter of course in order to be financially profitable."

现在是开始建立气候阳性未来的时候了。
