Bounded by the world renowned Victoria Harbour, the New World Centre is located in the prime waterfront location of Tsim Sha Tsui, with Salisbury Road to the north (Figure 4), Salisbury Garden and the Cultural Centre complex to the west and Victoria Harbour and a sea front promenade running south to east (Figure 5). The New World Centre has been a major hub for commercial, hospitality and entertainment in Tsim Sha Tsui since it first opened in After lengthy negotiations with the Buildings Department, Lands Department, and Planning Department concerning the remodeling proposal for the New World Centre, New World Development commenced the detailed planning and then the construction works of the new project on-site in The remodeling project commenced in phases with the demolition of the multi-story carpark and office block (i.e., east wing) in January Figure 5. View from Tsim Sha Tsui East (Source: New World Development Company Limited) 图5. 从尖沙咀东部角度拍摄 来源 新世界发展有限公司 The rest of the New World Centre was subsequently closed in March 2010 and demolition work commenced in January The Palace Mall in the adjacent lot was closed in February 2014 for alteration and addition work (Figure 6). The remodeling of the New World Centre is one of the most ambitious and comprehensive urban remodeling projects ever undertaken on the Tsim Sha Tsui waterfront in recent times. The focal point of the remodeled development is a mixed-use tower that comprises international Grade-A offices and a five-star luxury hotel with elaborate hospitality and dining facilities (Figure 7). Inspired by The Artisanal Movement of the New World Group, the remodeled New World Centre will create an attractive urban habitat with innovative design, sustainable green features and unparalleled architectural features that will engage the diverse users of the development and also the public at large.

5 Once the remodeled New World Centre is completed, it will spark revitalization to the waterfront and bring renewed vigor to the city. It will also reshape the skyline of Hong Kong on a rejuvenated hub of multiple attractions and offer to the bustling city of Hong Kong a refreshing urban oasis. Total GFA of the remodeled project will be 2,951,444 sq. ft. Embrace the Sustainable Building Design Guidelines Mainstream green building certification schemes, namely the US LEED and the UK BREEAM, are internationally acclaimed and well-established programs covering the complete life cycle of property development: siting, design, material selection, construction, operation, maintenance and waste disposal. While these certification schemes cover a wide-array of aspects in property development, they tend to be unattuned to local needs and in some cases have but scant relevance to densely populated cities like Hong Kong. In the spirit of fostering high quality and sustainable building environments, the Hong Kong Council for Sustainable Development, in collaboration with the HKSAR Government, conducted a public engagement exercise in 2009, which recommended a host of measures for enhancing building construction and overall design. Measures encompass the development of the Sustainable Building Design (SBD) Guidelines, gross floor area (GFA) concessions and Guidelines for the Energy Efficiency of Buildings. Following the completion of the study, the Buildings Department commissioned another consultancy study of building designs that support sustainability in an urban living space like Hong Kong. Acting on the findings of the study, the Government introduced its SBD Guidelines in 2011 in hopes of encouraging property developers and/or owners to accentuate sustainability elements in every building design, including the following: 1. Building Separation to improve ventilation and to enhance environmental quality at street level and to mitigate heat island effects arising from the undesirable screening effects of long buildings at different levels, length of a building should be in proportion to the width of the street, promoting permeability. Detailed criteria were developed such as permeable elements, separating distance and intervening space; 2. Building Setback to improve street level comfort, defined by the first 15m in height of the project; 3. Site Greenery to improve the environmental quality of the overall urban space. The focus is on street level and is aimed at mitigating heat island effects. The SBD Guidelines were introduced to encourage voluntary compliance and to further support the adoption of the Hong Kong Building Environmental Assessment Method (HK-BEAM) in buildings. Both the SBD Guidelines and HK-BEAM certification are prerequisites for GFA concessions 1 a strong incentive for developers in Hong Kong where land is scarce and land value is high. The Outline Zoning Plan and the SBD guidelines laid down a road map for architects to follow in terms of development potential and building disposition of the development. The General Building Plan of the New World Centre Remodeling Project was approved long before the introduction of the SBD Guidelines. To demonstrate the concept of sustainability, we took the initiative to revise the scheme and to improve the building design. The planning of this programmatically charged project on a site with an irregular shape is a daunting challenge. Nevertheless, New World Development decided to incorporate the newly established Guidelines into the remodeling project. We did so in a bid to create an overall design more in symphony with the urban environment in the vicinity. After months of revisions of building plans and design adjustments, the revised scheme has successfully demonstrated significant improvements in respect of visual and physical connections to the Victoria Harbour, cross ventilation to the urban environment as well as greenery provisions. This innovative and groundbreaking approach has set the remodeling project of New World Centre apart from other projects, as it was the only major development which opted for full compliance with the SBD Guidelines. 后, 屋宇署委托第三方进行了另一项关于建筑设计的咨询研究, 有助于在类似香港的城市生活空间推广可持续理念 根据研究结果, 香港政府于 2011 年引入 SBD 指导方针, 以期鼓励地产开发商和 / 或所有者在建筑设计包括以下方面强调可持续元素 : 1. 建筑隔墙 以改善通风并提高街面的环境质量, 高层建筑的不同层面会形成不尽如人意的屏蔽效应, 由此会产生热岛效应, 而此举有助于疏导热岛效应 同时, 建筑的高度应与街道的宽度成比例, 可提高透气性 已制定了详细的标准, 如透气元素 分割边距和间隔空间 ; 2. 建筑后移 以提高街面舒适感, 于项目的首个 15m 高度处测量 3. 现场绿化 以改善城市整体空间的环境质量 关注点在于街面, 旨在疏导热岛效应 引入 SBD 指导方针 的目的是鼓励自觉遵守并进一步促进在建筑中采纳 香港建筑环境评审法 (HK-BEAM) SBD 指导方针 和 HK-BEAM 认证都是获得建筑面积租让的前提条件 1 香港的土地不足且土地价值不菲, 这对香港开发商们来说是强有力的激励政策 分区计划大纲 和 SBD 指导方针 在开发潜力和开发项目的建筑配置方面对建筑师们具有指导意义 在颁布 SBD 指导方针 很久之前, 新世界中心改建项目的建筑总平图就已获得批准 为了体现可持续理念, 我们主动修改方案并改良建筑设计 在不规则形状的地块上采用编程方式对该项目进行规划, 本身就是一个艰巨的挑战 然而, 新世界发展有限公司决定, 改建项目将参照新版 指导方针 进行设计 我们之所以这么做是为了制定的整体设计可以更加和谐地融入邻近的城市环境 经过几个月对建筑平面图和设计调整的不断修改, 改版后的方案在与维多利亚港视觉和空间的连接方面 与城市环境对流通风及绿化规定方面已实现明显改善, 大获成功 这种开创性的创新方法已使新世界中心改建项目明显区别于其他项目, 这是唯一一个自主选择完全遵照 SBD 指导方针 进行设计的大型开发项目 1: A concession cap has been set at 10 % of the total GFA of the development. If a development comprises both domestic and non-domestic buildings or in the case of a composite building, GFA concessions for features serving the domestic part or the non-domestic part of the development will be calculated separately such that GFA concessions for each part will be capped at 10%, based on the total GFA of the respective part of the development (Buildings Department, 2014). 1: 租让面积的上限被定为项目总建筑面积的 10% 如果一个开发项目包括本地和外地建筑, 或为综合体建筑, 则开发项目本地建筑或外地建筑中符合要求的建筑面积租让值将予以分别计算, 如此, 基于开发项目中各个建筑的总建筑面积, 每个建筑的建筑面积租让值上限则定为 10%(2014 年屋宇署 ) 524 Next Generation, Large Scale Mixed-Use Developments 下一代大规模的混合使用项目开发

6 Sustainability in All Design Aspects Building Separation Urban developments across densely populated cities like Hong Kong are destined to encounter mounting environmental challenges. These include claims of diminishing air circulation resulting in hot air and wall effects, bellowing greenhouse gas emissions from heavy traffic and more. To address these problems, the SBD Guidelines include a series of recommendations on improving permeability and airflow within a property development. To comply with the principle of increasing natural ventilation, one of the innovative features of the remodeled New World Centre is a visual corridor of 20m in width and 8.4m in height on the ground level, to be aligned with Chatham Road. The opening will allow gentle sea breezes blowing onshore from the Victoria Harbour into Salisbury Road and serve as a generous and inviting visual corridor for all. This visual corridor will also open up an obstruction-free vista all the way from Chatham Road to the harbor, allowing passers-by on Salisbury Road and pedestrians to take in the stunning harbor at a distance while being connected to the waterfront at all times. In a step beyond the SBD Guidelines, the New World Centre has introduced a second visual corridor of 12.5m in width and 27m in height above the podium, enabling air to circulate through the opening from sea to inland. It will further connect the harbor with the passers-by and create a spectacular architectural feature of its own on the waterfront. Building Innovations on Setbacks In compliance with the Outline Zoning Plan, the hotel/office tower has been strategically located at the eastern end of the site, and has blended in well with the rest of the development. This core tower is recessed at the upper zone to form a distinctive setback, which will be used as a sky garden, seamlessly merging with the rest of the tower (Figure 8). To allow the maximum exposure to natural daylight and increase the flow of air, generous open space is provided at the ground level on Salisbury Road and also along the waterfront. Step-like recesses in the building profile are strategically created on different levels to enhance the liberating feel of open space. Site Greenery At all stages of its development and actual operation, the New World Centre has carefully considered the practical needs of users. The complexity of the development necessitates hard paved areas for vehicular drop-off and access for emergency vehicles as well as ample open space for public gatherings. After factoring in all the necessary functional areas, it became apparent that traditional ways of providing greenery would not be in line with the SBD Guidelines, and innovations would be necessary to introduce more engaging green elements. Designed with a lush garden in mind, the development is a multi-dimensional natural landscape with a variety of local and exotic plants, water features, green roofs, shaded areas and vertical foliage. All these features are melded into a perfect integration of natural space and local culture, allowing visitors to experience an urban oasis and to be inspired by the intimate relationship between humanity and nature. Green walls are graciously provided at various locations on the façade and innovative free-standing green columns have been installed as abstract landscape features along the waterfront. Moreover, flat roofs of the setbacks are transformed into various types of terraces, sky gardens and green roofs, where visitors and patrons can enjoy splendid outdoor experiences. Special features have been incorporated into the landscape design and use of greenery to increase biodiversity in the urban center. All the creative designs have been conceived by a world-renowned landscape designer (Figure 9). As of 2015, 98% of ongoing property projects in Hong Kong by New World Development have applied for the US LEED and/or the HK- BEAM certification. Over 90% of these projects are expected to achieve gold level certification or above. By referencing the SBD Guidelines in the New World Centre Remodeling Project, we are able to fulfill even more criteria required by both aforementioned green building certification schemes. All in all, very careful consideration has been given at every stage in the design of this mixed-use urban development. We have strived to bring new maximized green areas and provide a new kind of breathing space with lush landscapes for city dwellers. It will be a location offering a totally new green urban experience to the people of Hong Kong. Figure 8.

7 Sustainability Innovations The New World Centre is designed to provide a sustainable environment to the public and to its users. With 30% green coverage, the New World Centre offers flexible engineering equipment, which allows an adaptive and versatile layout, together with a quality indoor environment through its attainment of a good class in Indoor Air Quality (IAQ). The sustainable design of the complex has been recognized with a Platinum grade Beam-Plus provisional assessment; the most widely used green building labeling scheme in Hong Kong. Energy saving is the key to protecting the environment. In New World Centre, many active measures to reduce energy consumption have been applied, including low power lighting, energy saving seawater cooling and a solar hot water system. Energy saving is further enhanced by installing a high performance building façade, a high efficiency chiller system and a heat pump hot water system. An eco-friendly approach is fully incorporated in the design of the New World Centre. Green materials of highly recycled content from regional suppliers are employed as well as certified wood from sustainable sources. To further prevent environmental pollution, low VOC materials have been used in interior decoration and the air-conditioning refrigerant system is ozone-friendly. The New World Centre has also achieved 30% water saving by selecting effective water saving features and using rainwater recycling for irrigation. Architectural Design Features To fulfill the requirement of the SBD guidelines in an innovative way, New World Development has engaged the worldacclaimed New York-based architectural firm Kohn Pedersen Fox Associates to lead the architectural design of this project. Their concept blends the architectural languages of the program it houses: the city s most luxurious hotel, boutique office space and other multi-functional facilities with the three key sustainability elements in the building development. Like a great neighborhood, their program seamlessly connects rejuvenated networks of outdoor public space, gardens and terraces. The design of the hotel/office mixed-use tower matches the classical design elements with the hotel s vibrantly contemporary surroundings. The design of this iconic tower is inspired by a lighthouse guiding ships to safety, with 新世界中心的设计领先于 SBD 指导方针 的要求, 已引入第二条宽 12.5m 高出裙房 27m 的视觉走廊, 使得海风可通过入口流入室内 将进一步方便路人前往海港, 在海滨打造出自身绝妙的建筑特色 建筑后退的创新根据 分区计划大纲 的要求, 酒店或办公大楼已更改至现场东端最佳位置, 且很好地与开发项目的余下部分相融合 本座核心塔楼在高区内凹以形成独具特色的后退, 这里将会被用作空中花园, 与大楼的剩余部分无缝连接 ( 图 8) 为了获得最大的自然光并提高空气的流动, 宏大的开放空间被置于梳士巴利道地面上且沿着海滨 建筑物轮廓中类似台阶的凹进出现在不同的楼层, 以最佳的方式增强开放空间的释放感 现场绿化在开发和实际经营的各个阶段, 新世界中心都谨慎地考虑到了用户们的实际需求 这个开发项目的复杂性使得其需要为车辆落客区铺设硬面路区 为紧急车辆提供出入口及为公众聚会提供充足的开放空间 考虑到所有必需的功能性区域后, 传统的绿化方式明显将不符合 SBD 指导方针 要求, 此时需要通过创新引入更具吸引力的绿色元素 设计构想是一座郁郁葱葱的花园, 而项目实际具有多维的自然景观, 搭配各种当地和国外植物 水景 绿色屋顶 阴影区和垂直植物 所有这些特色都极好地融入进自然空间和当地文化之中, 游客在此可体验城市绿洲并感受人与自然之间的亲密关系 外立面上多处位置设有绿植墙体, 形态优雅, 而富有创新性的独立绿植支柱已完成安装, 成为水滨沿岸抽象的景观特色 此外, 后移建筑的平面屋顶被改建成多类露台 空中花园和绿植屋顶, 游客和客户们在这里可尽享绝佳的户外体验 景观设计中已设有特色景点, 并采用绿化增加城市中心的生物多样性 所有这些创新设计都来自于一家享誉世界的景观设计公司 ( 图 9) 到 2015 年为止, 新世界发展有限公司在香港所有在建房地产项目的 98% 已申请了美国 LEED 和 / 或 HK-BEAM 认证 预计这些项目中 90% 以上将至少获得金奖认证 通过在新世界中心改建项目中参考 SBD 指导方针, 我们有能力达到上文提及的绿色建筑认证方案中要求的甚至更高的要求 总而言之, 我们在设计这座城市的综合体建筑时, 认真研究了各个阶段 我们一直致力于为城市居民注入最大面积的新鲜绿地 以茂盛的景观带来新式喘息空间 这里将为香港人民带来全新的绿色城市体验 可持续性创新 新世界中心的设计目标是为公众及其用户提供一个可持续的环境 新世界中心的绿化覆盖率达到了 30%, 由于提供了灵活的工程设备, 项目可采用自适应且通用的布局, 同时还具有达到室内空气质量 (IAQ) 良好等级的高质量室内环境 该综合体的可持续性设计已获得了绿建环评新建建筑暂定铂金级的评估 ; 这是香港绿色建筑广泛认可的标志方案 节能是保护环境的关键 新世界中心内已采取多种积极措施以降低能耗, 包括低功率照明 节能海水冷却及太阳能热水系统 此外, 还安装了高性能的建筑外立面 高效的制冷系统和热泵热水系统, 进一步降低能耗 新世界中心的设计中充分融入了生态友好的概念 建筑采用了从地区供应商采购的高循环性绿色材料, 还有持续供应的认证木材 为了进一步控制环境污染, 室内装饰中采用低 VOC 材料, 空调制冷为无氟制冷系统 新世界中心通过采取有效的节水措施并选用雨水回收灌溉技术, 已节约了 30% 的水资源 建筑设计亮点 为了创造性地满足 SBD 指导方针 的要求, 新世界发展有限公司邀请了世界顶级纽约建筑事务所 KPF 建筑事务所 (Kohn Pedersen Fox Associates) 主导该项目的建筑设计 他们的概念融合了所容纳功能的各种建筑语言 : 该市最为奢华的酒店 精品办公空间及其他多功能设施, 同时兼顾建筑开发的三大关键可持续因素 他们的方案俨然是一处绝妙的社区, 与户外公共区域 花园和露台形成的网络无缝连接, 重现地区活力 对酒店 / 办公室综合塔楼的设计满足经典设计元素, 酒店四周的现代背景充满活力 这座代表性塔楼的设计灵感来源于指引船只安全航行的灯塔, 造型独特, 塔冠光彩熠熠, 在著名的天际线中一定一眼就能被认出 建筑设计的亮点是一系列配有露台的阶梯 塔楼的立面设计采用搭配丰富金属加以强调的石灰岩扶壁, 令人回想起传统建筑的元素 这些石灰岩扶壁之间是 3 米宽的窗体, 使低区办公室和高区酒店可纵览全方位 无遮挡的维多利亚港全景 为了迎合酒店闻名的特色绿化, 这里将设计多种适宜的绿化景观 除了满足 SBD 指导方针 的绿化要求, 景观设计还将补足并连通酒店上下及室内外的空间 新世界中心裙房的外立面采用横向连接的石灰岩带, 配有金属加以强调, 阶梯状的阳台 花园和石质橱窗是设计的点睛之 526 Next Generation, Large Scale Mixed-Use Developments 下一代大规模的混合使用项目开发

8 its distinct form and glowing crown that is destined to become an instantly recognizable icon on our famous skyline. The architectural design features a series of cascading perspectives with terraces. The elevation design of the tower includes limestone piers with rich metal accents that recall the elements of a classical building. In between these limestone piers, 3m-wide window modules provide both offices at lower zones and the hotel above them with a 360-degree unobstructed panoramic view of the breathtaking Victoria Harbour below. To celebrate the hotel as a destination renowned for its greenery, it will feature an abundance of appropriate landscaping. Apart from fulfilling the greenery requirements in accordance with the SBD Guidelines, the landscaping will complement and connect indoor and outdoor spaces throughout the hotel. The activated façade of the podium of the New World Centre horizontally articulated bands of limestone with metal accents, featuring terraced balconies, gardens and stone vitrines is designed to contrast the rectilinear geometry of the hotel/office tower. Generously planted green walls are provided to introduce nature in an exciting way. The terraces allow for formal and informal outdoor spaces linked perfectly with the indoor design. The terraces are also designed to take full advantage of its unparalleled views of the city and the harbor. The overall architectural design intends the use of a simple and consistent material palette that reinforces the holistic vision of the development, yet also presents various details and architectural moods that lead to exciting spaces and forms. The architectural intent of the project is to create a building that is like a vibrant and active city, which challenges previous assumptions about how a mixeduse development can interact seamlessly with city streets, public spaces and neighboring buildings. Conclusion In Hong Kong, buildings account for 90% of the city s total energy consumption and over 75% of its greenhouse gas emissions. With limited land available for future development, it is expected that many new buildings will be mixed-use in order to optimize space. These facts call for a thorough study of sustainable urban development and practical examples of its application. At New World Development, we find inspiration in The Artisanal Movement to innovate throughout our property portfolio and ensure each step delivers a unique solution in harmony with the intended end product. New World Development takes pride in being one of the first large-scale developers in Hong Kong to have adopted SBD Guidelines and have integrated their concepts in the remodeling of New World Centre. We are going even further by seeking green building and landscaping certification, to enable interesting interaction between people, art and nature. The redevelopment will redefine sustainable design in Hong Kong for years to come. 笔 旨在突出酒店 / 办公塔楼的直线几何结构 大面积栽种绿植的墙体将自然引入建筑, 令人兴奋 这些露台与室内设计完美衔接, 兼有正式 非正式的户外场地 设计这些露台也是为了尽享香港与这座港湾无与伦比的美景 建筑整体设计偏向简单且连续的材料配色, 以强调开发项目的整体观, 但仍呈现出各种引导的细节设计和建筑氛围, 烘托出令人激动的空间和形式 该项目的设计目标是创造一座类似活力 激情城市的建筑, 而这向此前对一座综合建筑与城市街道 公共区域及临近建筑无缝互动过程的猜想提出了质疑 总结 在香港, 建筑能耗占用该市总能耗的 90% 且排出超过 75% 的温室气体 可用于未来开发的土地资源有限, 因此, 人们期望新建筑多为综合建筑, 以优化空间资源 以上现实问题需要对可持续城市建筑及其应用实例进行彻底研究 在新世界中心项目中, 我们从工匠运动中获得灵感, 创新贯穿整个项目过程, 确保每一次制定的独特解决方案可融入预期的最终产品 新世界发展有限公司以成为香港首家采纳 SBD 指导方针 并将其概念整合至新世界中心改建项目的大型开发商为傲 我们不会止步于此, 下一步将申请绿色建筑和景观设计认证, 以便能激发人类 艺术与自然之间有趣的互动 这个再开发项目将重新定义香港未来几年的可持续设计 References: Glaeser, E.
