项目简介:
来自建筑师的介绍。从某种意义上来说,项目是同类型首个成功案例。这栋十层楼高的公寓(使用了近2700立方的CLT木材)打破了过去十年间从欧洲发源进而在全世界被实现的典型的大量木材设计的模式。项目最初版本被构思为传统模式,但后来客户Aveo在设计方Jackson Teece和建造商Strongbiuld的建议下,在设计里使用了CLT(cross-laminated timber:交错层压木材,一种新型木建筑材料),以彰显行业领导地位。
 
这个项目与其他近期完成的木材建筑的区别在于,对建筑表现和功能规划的关注超过了由建造效率驱动的设计。当混合施工方法应用(即将木材,钢和混凝土放在一起使用)还不成熟的时候。大量的的木材建筑外观通常是“四四方方”的,没有曲线的,将每层平面和伸出的阳台叠加,但这不是悬臂,立面轮廓上,由三个墙围绕支撑。
 
该项目的关键是要在建筑设计和施工之间取得平衡。为了实现弧形的公寓平面,一部分挑战来自于楼板之间的连接处,即复杂的混合钢结构和木结构的连接,看起来好似悬挑的阳台。由于市场对建筑中木材的认知,CLT元件采用防火材料包裹。建筑内部结构的体现来自一系列裸露的胶合木柱支撑着入口大堂的玻璃元素。
 
可以成功交付这个项目的关键是与前期客户的支持,投入和承诺,与施工方法有关的专家顾问意见,以及能力极佳的建造者是分不开的。 Jackson Teece与TDA和Wood Solutions一起组织了由客户,建造单位与TTW的结构工程师共同参与的一次对奥地利和瑞士的考察学习。 此举加深了团队对木材工程,制造和施工技术的理解,从而帮助增加了在澳大利亚实现类似可持续建筑的重要性。
 
原材料的采购来自奥地利的BinderHolz,这是一家CLT供应商,其生产基地符合并通过严格的PEFC标准认证。 它们在制造过程中的零浪费原则意味着使用了每棵树的100%。 生产CLT过程中产生的副产品包括树皮,切割片,木屑,锯末和刨花等都将被加工成颗粒或球状的生物燃料,或被转化为对气候中立的热能或绿色电力。目前在澳大利亚还没有像这样高效简洁的制造过程,来在很大程度上,抵消通过运输产生消耗的能量。
 
节能设计是整个项目开发的基础。总体规划中建筑物的交错布置以及建筑物的立面连接通过沿着建筑物立面,在连接处创造的不同的压力区域来帮助自然通风的实现。机械通风的控制区域考虑到减少能源的使用。所有住宅走廊都可以获得自然采光和通风,进一步减少使用机械通风的需求。机械服务专用于在这个大型木材建筑中实现额外的气密性,从而降低了维持制热和制冷的成本。建筑物中使用的大量木材中的连续碳储存也减少了其在建造和未来运营期间的碳足迹。
 
该提案旨在提高标准,不仅为用户提供优越的便利性,还通过使用CLT引领倡导可持续建筑技术。 使用该产品的优势不仅体现在对环境效益和施工速度上,还体现在前期设计分辨率上,最终使项目成果得到改善,产品质量更高。

Text description provided by the architects. Aveo Bella Vista is, in a way, the first of its’ kind. The design for this 10 storey residential apartment building (containing approximately 2700m3 of CLT) breaks the mould of the typical mass timber designs we have seen coming out of Europe and being realized internationally over the last decade. Originally conceived as a conventional build, Aveo were guided by Jackson Teece and Stongbuild to incorporate CLT into the design, to demonstrate industry leadership.
 
 
 
What sets this project apart from other recently completed mass timber buildings is the increased focus on architectural expression and functional planning over a design purely driven by construction efficiencies. Mass timber buildings to date are typically ‘boxy’ looking (no curves) with squared-off, strictly stacking floor plans and inbound balconies (not cantilevers, within the fa?ade outline, bound by 3 walls), while the application of hybrid construction methods (combining engineered timber, steel and/or concrete) is not yet well established.
 
 
This project had to achieve a balance between the desired architectural design outcome and the construction rationale. Some of the challenges involved complicated floor slab junctions, in order to realize the desired apartment layouts and sophisticated hybrid steel and timber connections to achieve the curved, seemingly cantilevered balconies. Due to the market perception of timber in construction, CLT elements were also clad and wrapped in fire-rated material. As a reflection of the internal structure of the building, exposed timber elements in a series of Glulam columns support large glazing elements to the main entry lobby.
 
 
Key to the successful delivery of this project was early client education, enthusiasm and commitment, specialist consultant input relating to the construction methodology, and a capable builder. Jackson Teece, together with TDA and Wood Solutions organised a study tour to Austria and Switzerland with the client, builder and TTW structural engineers. This deepened the team’s understanding of timber engineering, fabrication and construction technologies and as a result, has increased the prominence of this sustainable construction methodology in Australia.
 
 
The raw material was sourced through BinderHolz in Austria, a CLT provider whose production sites meet and are certified under strict PEFC standards. Their no-waste principle during fabrication means that 100% of every logged tree is used. Production by-products such?as bark, cut-off pieces, wood chips, sawdust and shavings are processed into biofuels in
 
 
the form of pellets and briquettes or converted into climate-neutral thermal energy or green electricity. Such highly efficient and streamlined fabrication processes, currently not available in Australia, offset the embodied energy generated through transportation to a large degree.
 
 
Energy efficient design has been fundamental throughout the project’s development. The staggered arrangement of buildings within the masterplan as well as the building’s fa?ade articulation aids natural ventilation by creating different pressure zones along the face.?Zonal control of the mechanical ventilation allows for reduction of energy use. All residential corridors have access to natural light and ventilation, providing air to the units and further reducing the need for mechanical ventilation. Mechanical services have been specifically designed for the additional air tightness achieved in this mass timber building, thus reducing ongoing operational costs for heating and cooling. Continuous carbon storage within the significant volume of mass timber used in the building further reduces its carbon footprint, during its construction and in future operation.
 
 
The proposal aspires to raise the bar not only in providing superior amenity to the user,?but also spearheading sustainable construction technology through the use of CLT. The advantages of using this product are not only seen in the environmental benefits and speed of construction, but also in the upfront design resolution, ultimately resulting in an improved project outcome and a high quality end product.
