Foreword 主席的話

T

he Hong Kong Green Building Council (HKGBC) has been actively promoting sustainable development at every phase of the building life cycle since its establishment in 2009. In April 2010, we introduced the new BEAM Plus assessment tool, which has since received widespread industry acclaim. Due to its effectiveness, this assessment tool has even been adopted in the Hong Kong Government policy.

Thanks to the active involvement of both the Government and industry stakeholders that such great progress has been made in the space of just a few years.

environmental and energy-saving initiatives.

Likewise, Ir Cary Chan of Swire Properties, which is one of the HKGBC’s Platinum Patron members, shares his experiences of the company’s long-term plan to achieve energy savings. You can also read an inspiring interview with the founding chairman of the HKGBC, Ir Dr Andrew Chan, who will talk about the history, milestones, present and future of the HKGBC, as well as the sustainable development of green buildings in Hong Kong. Readers of GreenMAG can rest assured that they always receive the latest information and insights direct from the HKGBC!

As the chairman of the HKGBC, I am excited and very pleased with these excellent results, and I strongly believe that Hong Kong’s many advantages will ultimately earn it global recognition as a leading “low-carbon metropolis”! While the industry continues to dedicate much time and effort to achieving this goal, the widespread support from the community is equally important. Recently, the HKGBC proposed the “Hong Kong 3030” campaign, with the aim of reducing the absolute electricity consumption of Hong Kong’s buildings by 30% of the 2005 levels by the year 2030. To achieve this goal, this campaign needs substantial public participation because it requires members of our society to change their existing habits and question some of their outdated ideas and beliefs. With this in mind, the HKGBC has committed itself to public awareness building, not only to promote ourselves, but also to keep the society fully informed about the industry’s progress and its vision of green building. GreenMAG is a key initiative of this new outreach programme.

The launch of GreenMAG is only a small part of our full vision for promoting sustainable building. However, by successfully taking a first step with this inaugural issue, I deeply believe the magazine will establish a valuable link between the industry and the public. While sharing news of the industry’s latest developments is certainly one of our targets, we also wish to promote the concept of green building and encourage everyone to live an environmentally friendly lifestyle. By creating a forum in which the industry and the public can work together side by side, I believe GreenMAG is enabling a significant step toward the development of green building in Hong Kong and, ultimately, throughout the world!

To further promote the “Hong Kong 3030” campaign, the theme of this inaugural issue of GreenMAG is “Energy Reduction”. The Cover Story introduces four outstanding projects that have achieved a Final or Provisional Assessment of BEAM Plus Platinum rating. In the article, project leader from each project discusses its use of the latest energy-saving equipment and technology, as well as other green features. We have also invited the President of the Hong Kong Federation of Electrical & Mechanical Contractors, Ir Dr Otto Poon, to share his thoughts on the current trend and future development of the industry’s

I wish to sincerely thank all the interviewees and experts in this issue, as well as the publishing and production team that have contributed to the birth of GreenMAG. To our readers, if you have any comments or feedback regarding the magazine, please feel welcome to let us know. We will continue to strive for excellence, and look forward to bringing you lots more exciting content in future issues.

Director's Interview

A Foundation Well-laid n any conversation with Dr Chan, it quickly becomes apparent that his enthusiasm for green development is both a professional and a personal p a s s i o n . “A ro u n d a d e c a d e a g o,” he explains, “our company identified the challenges the world was facing as o u r d r i ve r s fo r d e ve l o p m e nt s u c h a s urbanisation, climate change and fuel shortages. I believe we are duty bound to help tackle these problems. We also play an important role in areas like building and transportation as industry professionals.”

In 2008, Mrs Carrie Lam, the then Secretary for Development, united industry parties by initiating the setting up an overarching body for sustainable building development in Hong Kong. Dr Chan was involved in the co-ordination works, and was then entrusted with the responsibility of being the Founding Chairman of the HKGBC in 2009. “Mrs Lam is the key person behind the birth of the HKGBC,” remarks Dr Chan, taking no credit for its success. “The support from the Construction Industry Council is equally important as it is the single organisation linking up all stakeholders in the construction industry, and it takes the lead in terms of funding. Of course, it naturally took time to unite our visions because we were all used to focusing on our own areas.” Still, by sharing a clear goal of building a sustainable community, all the founding members have generally been able to work together and create a solid foundation for Hong Kong’s sustainable built environment.

A New Era of Unprecedented Opportunities Dr Chan believes that Hong Kong is wellpoised to be an international leader in green building and urban development. For instance, Hong Kong’s locally developed BEAM Plus assessment tool takes into account Hong Kong’s unique conditions such as its high development density and naturally hot, humid weather. This is not only helpful for green developments in Hong Kong, but also creates the potential to set a new benchmark of excellence for the entire region. By utilising this marketleading tool, developers can launch high

quality new green building projects. Indeed, Dr Chan explains that by planning ahead, the additional capital investment required for a green building is minimal, yet the longterm cost savings are so substantial that developers can make the building a model for others. As more and more successful examples come to market, increasing numbers of developers are being inspired to follow suit. Dr Chan is When people look for state-of-thealso keen to point out one of the art green building technology, they unique features of Hong Kong’s could look to Asia, a part of the world property industry. “ The local private sector only consists of a we play a key role in. handful of key players. If these emphasis on the need to leverage China’s players are all on the same page, progress rapid urbanisation. “Cities in China are can actually be achieved easily.” similar to Hong Kong in terms of its urban development, its density and its focus on From a policy perspective, Dr Chan believes that our Government has shown real leadership over the years. For example, the requirement of all new buildings wishing to receive gross floor area (GFA) concessions for green features to undergo BEAM Plus assessment is a major game-changer. Since its introduction in April 2011, the number of buildings registered for assessment rapidly increased. Dr Chan regards this policy as “the most important step” so far in pushing green building development. “I think many people are not aware that the vision and standards of some of our Government initiatives, such as the Air Ventilation Assessments (AVA), are amongst the best in the world, matching high-rise buildings. If we can develop good those of Germany and Japan. It’s worth solutions for the design and operation of recognising because these initiatives are not modern high-rise green buildings, we will only positively affecting the construction of individual buildings, but also the overall form be the leading exemplar of worldwide urban of our city in the long term.” At the same development.

Dr Chan explains that his sincere hope is that the new generation of industry professionals will share his ambition for global success.

“We really can go international,” he says, with enthusiasm. He continues to point out that we are already a relatively sustainable city and that we possess many world-class elements of a sustainable built environment,

Maybe in the distant future, terms like ‘green buildings’ will become obsolete as green standards will be the established norm!

Going Green with Ambition and Passion Green building and environmental awareness in Hong Kong have come a long way since the 1990s, and Dr Chan has been present every step of the way. In recent years, he channelled his passion in yet another field of expertise – city planning. “We’re now seeing rapid development in mainland China’s cities,” he explains. “If the wrong route is taken in the planning of buildings, infrastructure and energy production, etc., there will be serious environmental consequences to live with for decades to come”.

but we seldom demonstrate them to others on the international stage. “Developing areas such as the Middle East understand that we are more competitive than Europe and America in providing relevant and costeffective solutions. We can then attract others to learn from us while at the same time exporting our expertise.” In fact, Dr Chan predicts that in 10 years’ time, “when people look for state -of-the -ar t green building technology, they could look to Asia, a part of the world we play a key role in.”

As for future trends in local built environment, he predicts that the scarcity of land in Hong Kong will lead to more urban revitalisation, which is an opportunity to transform a distric t into a greener environment. Building per formance benchmark ing is another key area of development, and one in which the HKGBC can play a major role in facilitating the sharing of data, inducing peer pressure and motivating owners to retrofit existing buildings. “The extensive participation of industry players should be able to make this happen,” he predicts.

While he acknowledges the importance of professional contributions to the green building industry, he also realises that behavioural factors and public education are equally important. The next generation i s i n c r e a s i n g l y a w a r e o f h u m a n i t y ’s responsibility to the Ear th, thanks to the green culture now star ting to be embedded in school curricula. People are also increasingly aware of saving electricity in various ways, such as by turning off idle lights and other electrical appliances. With the HK3030 campaign recently launched by the HKGBC, Dr Chan considers the aim of reducing the absolute electricity consumption of buildings by 30% of the 2005 level by 2030 a very “achievable” goal.

“In terms of public advocacy and education, the HKGBC has been quite successful.

Previously we were only known within the industry, but we have since reached out and contributed to positive behavioural change in working and living environment.

We will continue to do this. Maybe in the distant future, terms like ‘green buildings’ will become obsolete as green standards will be the established norm!”

With his profound vision and experience i n t h e i n d u s t r y, I r D r C h a n o f f e r s a n inspirational and highly personal account of the development of green building and the potential role it can play in the city’s future growth. Although local development is still at a relatively early stage, every party in the local industry is committed to further improving Hong Kong’s green building standards so as to achieve longterm sustainability, regional leadership and ultimately, as Dr Chan’s company motto suggests, ‘shape a better world’.

Mind Renovation: Driving Green Building Standards

E

ven back in its establishment in the early 1970s, Swire Properties placed considerable emphasis on the environmental impact of its development projects. For example, Taikoo Shing was Hong Kong’s first large-scale, landscaped estate project. For the later construction of Pacific Place, the company spent HK$20 million to preserve a century-old tree. “At that time, the concept of green building and environmental protection in the community was very vague,” recalls Ir Chan. “The Government did not have any relevant policies or measures to promote green ideas or sustainability. Nonetheless, we understood that construction had a profound effect on the environment, and so we decided to take the lead within the property industry to highlight the importance of environmental protection in our work.”

In 1995, Swire Proper ties and the construction industry led the development of the BEAM certification tool. This was in keeping with Ir Chan’s personal belief that property owners must lead by example, in the hope that architects, consultants and other professionals would be increasingly eager to gain deeper insights and more knowledge on the subject, which in turn could promote the development of green building throughout the industry. “It proves that the company was on the right track,” Ir Chan adds.

I r Chan refers to Island East as Swire Properties’ “land of fortune”, and expressed his hope that the community development model would induce synergy for sustainable development. As ear ly as dur ing the construction of Taikoo Shing, for instance, Swire Properties was acutely aware of the project’s potential to enhance the sense of community in the area and improve the surrounding environment.

The green facilities implemented in the office complex TaiKoo Place were all designed to serve the entire community, with features such as seawater-cooled air conditioning systems, heat recovery wheels, an automatic tube cleaning device for AC systems, energy-efficient lighting, the use of natural light, pedestrian bridges between buildings, green roofs, rainwater collection and reuse, waste recycling centres and more.

Since the completion of One Island East, Ir Chan has been working with his team to constantly generate new ideas and research the feasibility of adding yet more green elements to the area in order to maximise its advantages.

Patron Member's Interview

“For individual buildings, opportunities for improvement and their impact are relatively less significant and extensive,” he explains.

“That’s why we think on a community level with the goal of adding more green features and facilities, setting a benchmark for the whole industry.” Ir Chan is particularly focused on innovative improvements while setting standards and developing new projects, which is also in keeping with the “mind renovation” ideals of Confucian philosophy.

in extensive research into the continual improvement of its energy performance, including data collection, developing an inhouse database, and conducting energy analysis. Likewise, in response to climate change, the Swire Group set a “'Best in Class” benchmark target in 2006, and thereafter shifted its focus from the micro issue of saving energy to the macro issue of carbon reduction, a move which continues to define its main objectives in its long-term energy management strategy.

We understood that construction had a profound effect on the environment, and so we decided to take the lead within the property industry to highlight the importance of environmental protection in our work.

In-depth Analysis: Planning for a Decade

Ir Chan believes that the key to success in all these endeavours is detailed data analysis.

“We carefully collect and consolidate all data from various systems and energy consumption modes of our properties,” he explains. “By doing this, we can obtain solid information and set more realistic and achievable targets for energy efficiency, and then proceed to develop methods to meet such targets.” This meticulous strategy is also powerful proof of Swire Properties’ dedication to “studying the phenomena of nature in order to acquire knowledge”.

Properties incorporates the Great Learning ideal in its employee engagement strategy, by helping staff learn more about the importance of sustainable development.

In 2009, Swire Properties developed a 10year energy reduction plan and committed an investment of HK$300 million to its success. The goal was to reduce the overall e l e c t r i c i t y co n s u m p t i o n o f i t s m a j o r investment properties by 20% from 2008 level by 2020. After a review of its longterm energy management strategy in 2011, the company decided to shorten the planned timeframe and set an even earlier target date of 2016. Ir Chan recalls how the Chief Executive, Mr Martin Cubbon, asked, “Since we already know how to meet the target, why not make it happen within five years?” That simple question indicated the management’s strong support for improving Swire Properties’ energy-efficiency.

In order to meet its energy-efficiency targets within five years, Swire Properties approved the enhancement of plants and major equipment across its properties. For example, the chiller plants in Pacific Place and Cityplaza were upgraded with more energy-efficient chillers, a measure which resulted in a reduction of 11 million kilowatt hours of energy per year, equivalent to 8,690 tonnes of carbon dioxide. In TaiKoo Place, the company switched to using T5 fluorescent lights, LEDs and induction lamps, and installed photo and occupancy sensors to monitor and control the usage conditions and lighting levels, which ultimately enabled an annual energy saving of some 2 million kilowatt hours.

S i n ce a s i gn i f i c a nt p e rce nt a g e o f i t s developments’ power consumption is driven by tenants, Swire Properties has offered free energy audits to its office tenants, helping them to better understand their patterns of energy use and identify new ways of saving energy. These energy audit services have been welcomed by tenants. By the end of 2011, Swire Properties had conducted audits for 2.4 million square feet of office space.

Swire Properties has been implementing knowledge-based energy management strategies since 2001, and has invested

Moreover, Swire Properties proactively promotes its effor ts in sustainable development to others. Ir Chan explains that it is noteworthy, for instance, that the research results from the collaboration between Swire Properties and Tsinghua University have now been recognised and acknowledged by the Chinese Academy of

The data gathered provides a foundation for the design of future projects. Swire Proper ties now has the capability, for instance, to carry out computerised fluid dynamics simulations for air ventilation assessments. “We can now run simulations early in the conceptual phase, to study various ways to mitigate a project’s impact on the environment,” says Ir Chan.

Early in 2006, Swire Proper ties began collaborating with Tsinghua University in researching high energy- efficienc y building designs and operation techniques, and subsequently shared its research findings within the industry. In 2011, the Joint Research Centre for Building Energy Efficiency and Sustainability was set up, and in the period of 2011-2013, a budget of US$1 million per year has been allocated to the promotion of further technological research.

Global Leadership: Recognised

by All I n a d d i t i o n to i nve s t i n g i n t h e r i g h t hardware equipment, Swire Properties also places strong emphasis on the effective development of talent. The company currently has 35 BEAM Professionals (BEAM Pro) and expects to have another 15 to 20 people in training within the year, while some are also certified as LEED APs by the Leadership in Energy & Environmental Design (LEED) of the United States.

新民有道 推動綠建標準

早

於七十年代成立之初，太古地 產已相當注重發展項目對環境 的影響，例如太古城是當年全 港首個擁有園景設計的大型屋 苑，其後興建太古廣場亦投資 二千多萬港元保育一棵百年古樹。陳永康憶 述：「記得當時社會上對綠色建築及環保的 概念非常模糊，政府亦沒有任何相關政策， 但我們意識到建築對環保有着深遠影響，因 此決心帶頭改變業界，以行動展示對環保的 重視。」1995 年，太古地產與業界率先發展 BEAM 認證工具。陳永康認為只要業主以身 作則，建築師、顧問等專業人士就會作好準 備，發展相關知識，自然能有效推動整個行 業在綠色建築的發展。「事實證明，當時的 方向絕對正確。」 另一方面，陳永康提到港島東區為太古地產 的發跡地，因此亦期望區域性的發展模式能 令可持續發展事半功倍。早在建設太古城時， 太古地產已重視藉項目加強社區歸屬感及改 善周邊內外環境。現時太古坊商貿區的綠色 設施，例如海水水冷式空調系統、熱回收轉 輪、空調系統的自動管道清洗裝置、高效能 照明和提升天然光的裝置、各商廈間的天橋 連接網絡及其上蓋的綠化、雨水收集及循環 再用和廢物回收中心等，同樣以社區為本。 在港島東中心建成後，陳永康現時仍與團隊 不斷構思和研究在區內加入更多綠色元素， 將區域優勢發揮得淋漓盡致。「單一建築物 局限性較大，能做到的不多。因此我們希望 以整區作全盤規劃，嘗試盡量加入更多環保 設施，供同業作借鏡。」陳永康無論在制訂 標準或建設項目上，都着重革新求進，然後 推己及人，正是「新民」之意。

格物致知 訂立十年大計 2009 年，太古地產訂立了一個投資三億港元 的「十年大計」，計劃在 2020 年前將旗下 香港主要投資物業的耗電量，從 2008 年的 水平減少 20%。公司在 2011 年檢討長遠能 源管理策略後，決定縮短計劃時限，將達標 日期提前至 2016 年。陳永康回憶當時行政 總裁郭鵬說：「我們既然已知道如何能達標， 為何不在五年內完成？」由此可見公司管理 層對節能的大力支持。 為了能在五年內達到節能目標，太古地產通 過優化物業的機器和設備，例如把太古廣場 和太古城中心的製冷機更換成節能製冷機， 減 少 每 年 1,100 萬 千 瓦 小 時 能 源， 相 等 於 8,690 公噸的二氧化碳。在辦公樓雲集的太古 坊，公司更換 T5 燈管、LED 燈和無極燈，亦 安裝了可偵測使用情況和照明水平的感應照 明，減少 200 萬千瓦小時能源。 物業不少的耗電量來自租戶，太古地產為他 們進行免費能源審核，幫助他們了解自己的 能源使用模式和找出節省能源的方法。能源 審核服務廣受租戶歡迎，截至 2011 年底， 太古地產已為 240 萬平方呎的辦公樓總面積 進行能源審核。

我們意識到建築對環保有着 深遠影響，因此決心帶頭改變 業界，以行動展示對環保的 重視。 太古地產自 2001 年起開始實行以知識為本的 能源管理策略，致力進行大量研究。當中包 括成立能源數據庫，自行收集及分析各項數 據，務求可持續提升能源效益的表現。2006 年，太古集團訂下在應對氣候變化達至「業 界最佳」基準的目標，太古地產於是將重點 由微觀的節能擴展至宏觀的減碳，進而訂立 長遠的能源管理策略。陳永康認為成功關鍵 正在於詳盡的數據分析：「我們將旗下眾多 物業不同系統和各種耗能模式的數據整合後， 就可得出更實際可行的能效目標，並制訂達 標的方法。」這策略體現太古地產力求「格 物」、「致知」的認真態度。 這些運作數據亦為設計未來項目提供基礎， 例如以流體力學模擬分析空氣流通評估都不 假外求。陳永康指出其優勢：「我們可以早 在構思階段就可以先行模擬，研究各種減輕 對環境影響的方法。」太古地產早於 2006 年便與清華大學合作，對高效能建築及運行 展開研究，研究成果更與業界分享。於 2011 年更成立「建築節能與可持續發展聯合研究 中 心 」， 在 2011 至 2013 年 期 間 每 年 撥 款 一百萬美元推動技術研究。

齊家治國 深受中外認同 各項硬件準備深入充足之餘，太古地產亦非 常着重人才培訓。公司現有 35 位綠建專才 （BEAM Pro），今年預計可再培訓多 15 至 20 人，亦有美國領先能源與環境設計（LEED AP）的認證專才。公司更經常邀請海外頂尖 專家與員工分享經驗，又舉辦多項活動以求 「齊家」，令員工親身認識可持續發展的重 要性。 太古地產更積極將可持續發展推而廣之。陳 永康表示公司與清華大學的研究成果獲中國 工程院肯定，足以影響中國節能建築策略。 此外，太古地產不但參與國際能源署的工作 小組，將研究成果帶到國際舞台，更主動與 英美的主要物業發展和管理公司共同發起基 準調研。結果發現太古地產在能源管理上早 已比海外同業領先數年。加上多項國際團體 所頒贈的獎項，正正肯定太古地產多年的努 力，成功將公司的理念推展至「國」和「天 下」。

陳永康在訪問中，以實實在在的成果，說明他如何在可持續發展的路上，以全方位深入探究的 方式，以終為始，「止於至善」，訂下最終極的目標後，循序漸進在各個層面帶來改變。相信 太古地產日後定能為創造更清新的香港和世界，力臻卓越，繼續身體力行「大學之道」。 太古地產是香港綠色建築議會（議會）的鉑金贊助會員，而陳永康本人亦循商界環保協 會加入議會，可謂淵源甚深。陳永康盛讚議會在短短數年間的成就，特別是得到政府認 同，將綠建環評納入政策當中。展望未來，他擔任主席的議會業界標準及研究委員會正 進行多項研究，包括能源相關的基準系統，期望能成為本港主流。他又深信香港要成為 國際其中一個最佳綠建城市，指日可待。

Cover Story 四大綠建環評鉑金項目

節能減排各擅勝場 Hong Kong’s Four BEAM Plus Platinum Projects:

Energy Saving in Action

Few people are aware that buildings account for 90% of the Hong Kong’s total electricity consumption. If these buildings could be made more energy-efficient, Hong Kong would take a big step closer to becoming a more eco-friendly and sustainable community. Energy-efficiency, therefore, is a key criterion of the BEAM Plus assessment scheme. When developers take the initiative to earn a BEAM Plus Platinum rating, they not only create an energy-efficient building, but also help to promote green construction in Hong Kong. To help you understand more about this important scheme and some of the local developments that are helping to redefine green construction in Hong Kong, GreenMAG invites you to visit four BEAM Plus Platinum projects in the territory. These include Hysan Place and Holiday Inn Express Hong Kong SoHo which have passed the Final Assessment, as well as the provisional Platinum-rated Ex-Yuen Long Estate project and Hong Kong Science Park Phase 3 project. Let’s take a look at their innovative energy-saving technologies and other green features!

未 必 人 人 知 道， 建 築 物 佔 全 港 九 成 的 用 電，若建築物能做到節能減排，對香港可 持續發展必定事半功倍。因此，在綠建環評 （BEAM Plus）的評核項目中，「節能」 一項的比重最高，而發展商如能積極取得 鉑金佳績，更可大大推動本港綠色建築發展 步伐。《GreenMAG》今期遊遍港九新界， 走訪四個不同範疇的鉑金級出色項目，分 別為獲得最終鉑金級別的希慎廣場及香港 蘇豪智選假日酒店，以及取得暫定鉑金級 別的前元朗邨項目及香港科學園第三期， 並由項目負責人現身說法，展示當中嶄新 的節能設備和其他綠色設施。

Design with Unique Concept 項目理念各有不同

Hysan Place Hysan Place is located in Causeway Bay, one of the world’s most expensive and vibrant areas. The population density in this neighbourhood means that the pollution level is more severe than elsewhere in Hong Kong. “Hysan Place is not only a green building that has both energysaving capabilities and a reduced carbon footprint,” explains Dr LK Chan, Director of Design and Project of Hysan Development Company Limited. “We have given this project a unique vision and mission of helping to reduce the problem of pollution in the Causeway Bay area. Although it is only a single building and may not contribute much, we still want to take the initiative.”

希慎廣場 希慎廣場位處世界最昂貴及繁華的地段之一銅鑼灣，人煙 稠密令污染更形嚴重。希慎興業建築設計及項目總監陳麗喬 博士表示：「集團除希望興建一座節能減排的綠色建築外， 還有一個特殊的理念和使命，就是協助解決銅鑼灣的地區 污染。雖然項目只是單一建築物，不可能一下子帶來極大 改善，但我們認為值得帶頭盡一分力。」

Ex-Yuen Long Estate The Ex-Yuen Long Estate development project is the Housing Department’s first public housing project graded with a BEAM Plus Provisional Platinum rating. “The Department is committed to integrating green features into its development projects,” explains the Housing Department’s Chief Architect, Mr Ken Cheung. “After the Buildings Department launched gross floor area (GFA) concessions with BEAM Plus registration in 2011, the Housing Department decided to further enhance its standard specifications by achieving a minimum of BEAM Plus Gold rating in any development projects, thus increasing the number of dwelling units that can be built from the extra GFA granted.” He further explains that every development plan must take into account the social, economic and environmental considerations of the community mainly from the grass root sector. Therefore the Housing Department is taking the lead in integrating passive design that blend with the local environment and better adapt to the micro climate conditions. These measures are fully tailored to local conditions and make optimal use of natural resources. As such, they not only meet the needs of the community to the greatest extent possible, they also provide comfortable living and cultivate a sense of sustainable development for the community.

前元朗邨 前元朗邨發展項目是房屋署首個取得綠建環評暫定鉑金級的公營房屋項目。房屋署總設計師 張冠城說：「房屋署一直致力將環保設施融入項目。隨着綠建環評及屋宇署於 2011 年推出的 總樓面面積寬免要求，房屋署進一步優化標準範本，使任何工程均能達至綠建環評的金級水平， 以獲得更多的總樓面面積增加可建公屋單位數量。」他亦提到公營房屋住客為基層市民，發展 計劃需要顧及社會、經濟和環境的不同需要，因此項目會以被動主導的綜合設計策略，盡量配 合該區的環境及氣候因素，因地制宜，善用自然資源，並盡量切合社區的需要，為區內提供一 個舒適的居住空間及可持續發展社區環境。

Hong Kong Science Park Phase 3 Hong Kong Science and Technology Parks Corporation has always been committed to promoting sustainable development. In 2011, construction started on the development for Hong Kong Science Park Phase 3, which features a total of 39 passive, active and renewable energy green design features. Mr Dickson Wat, Senior Manager (Projects) at Hong Kong Science and Technology Parks Corporation, explains that the design of this third phase uses “back to basic” as its design concept and slogan. He is convinced that by getting the project’s eco credentials right from the very beginning, not only will the company save time and effort, it will also create an excellent foundation for the addition of further energy-saving and other green components in the future.

There will be more green building designs incorporated into the Phase 3 of the Hong Kong Science Park 香港科學園第三期將融入更多綠色建築設計

香港科學園第三期 香港科技園公司一直致力推動可持續發展， 在 2011 年動工的香港科學園第三期，結合 了多項被動式、主動式及可再生能源的綠色 設計共 39 項。香港科技園公司工程高級經理 屈漢邦表示第三期的設計以「回到簡約」為 理念和口號，並深信只要踏出方向正確的第 一步，往後加入其他節能環保設計就會事半 功倍，得心應手。

Hysan Place

希慎廣場

Hysan Place is specially designed according to the micro-climate in the area, enabling it to blend seamlessly with its surrounding environment. As there are lower buildings in the neighbourhood, the team has been able to create three “Urban Windows” that help retain good visual permeability, optimise natural breezes to improve overall air ventilation and reduce the “wall effect” often found in dense high-rise environments.

These “Urban Windows” also provide green spaces to mitigate the heat island effect that is so common in urban areas. Meanwhile, considering sunlight of different directions, Hysan Place uses light shelves to direct natural light deep into each office floor on the South and East sides, while the West side of the building has installed specially designed low-angle solar shadings. “The design of each side of the building is defined by the environmental factors in that specific location,” adds Dr Chan. “The four sides all have a different appearance, but collectively they look very natural together.”

希慎廣場在設計時特別研究區內的微氣候， 以配合周遭環境。他們利用四周較矮的建築 物配合夏天南風吹送，共設計了三個「城市 綠窗」，使建築物比一般的通透，從而加強 通風，減低屏風效應，而在綠窗內進行綠化 又可減低熱島效應，一舉兩得。同時，因應 項目四方日照程度不同，於日照較多的南面 和東面，他們運用反光板將陽光反射入室內， 而西面則特設針對低角度陽光的垂直遮陽板。 陳麗喬說：「我們會視乎每邊不同的環境情 況進行設計，因此廣場四邊的外觀各有不同， 但卻又相當自然。」

The Urban Windows create green spaces at different levels 位於不同層數的「城市綠窗」，創造不少綠化空間

Integrating Design with Environment 環境與設計相配合 Holiday Inn Express Hong Kong SoHo “In hotels especially, there is high demand for electrical power,” explains Ir Antonio Chan.

“Energy consumption is dominated by air-conditioning and hot water supply systems. As a result, this hotel uses a number of innovative and energy efficient systems in both its electrical and mechanical designs. For instance, we installed motorised roller blind system controlled by the room access card for each guest room as well as energy efficient lighting system. This will significantly reduce air conditioning, lighting and other electrical power consumption. In addition, to make use of the sunlight on exposed areas of the hotel, we have installed a solar hot water system. Solar Hot Water Cladding system on façade curtain wall likewise enables us to directly use solar thermal energy for water heating.” To further complement these initiatives, the hotel has a green roof to reduce the temperature inside the building and lower the need for air conditioning.

香港蘇豪智選假日酒店 對於酒店的節能設施，陳紫鳴介紹道：「酒 店對電力需求極大，當中以冷氣及供應熱水 系統為主。為此，酒店特別在機電方面加入 多項環保設備。我們在房間裝設與房卡系統 配合的預設電動窗簾、分散式智慧照明控制 系統等，以減省冷氣、照明等電力消耗。另 外，配合酒店位置所受日照，除裝設太陽能 熱水器集熱系統外，更設太陽能熱水幕牆板， 直接吸收太陽熱能為用水加熱。」此外，酒 店亦設有綠化天台，以減低大廈內的溫度， 同時減少冷氣消耗。

Ex-Yuen Long Estate With limited space available on the project site, Mr Ken Cheung acknowledges that it was a great challenge to achieve site greening. The design teams dedicated significant effort and creativity to adding greening to the ground area, podium terrace, rooftop and wall surfaces. As a result, green coverage accounts for some 30% of the entire building, which is a very encouraging goal for small development site. A rainwater collection system will also be installed on the estate for irrigation purposes. To suit the surrounding environment and climate, the project has been purposely laid out as a twin-tower design: a relatively-lower North block (18-floor) and a higher South block (29-floor). The shorter North block will help to block the fixed noise from the adjacent railway line, and yet will not interrupt the view of tenants in the taller South block. The stepping height of the two blocks will likewise enhance air ventilation and encourage more natural light. With good use of greenery and appropriate exterior rendering, the design will help minimise the heat island effect for the adjoining neighbourhood. “Located in Yuen Long district, the taller South block will partly shield off the intense sunlight for the shorter one,” adds Mr Cheung. “In the morning, the sides with external corridors will prevent direct sunlight entering the flats from the east. The structural wall facing the west will also block sunlight penetration. It is fair to say that this project is geographically positioned that every design feature could reap the best benefits of the sun path and wind flow.”

The roof top of both blocks will be used for installing photovoltaic panels and setting up a green roof respectively 天台分別會裝設光伏板和進行綠化，善用空間

前元朗邨 張冠城表示項目佔地不多，提升地盤綠化環境的挑戰很大，所以設計團隊花盡心思在地面、平 台頂及垂直地方進行綠化，最後，綠化面積佔整個體項目達約 30%，成績令人鼓舞，並在邨內 設置雨水採集系統供灌溉之用。另外，為配合附近環境及氣候，項目特別設計成兩幢分別高 18 及 29 層的大廈，北座低而南座高。低座可阻隔西鐵噪音，又不會阻擋高座住戶的景觀，而高 低座向亦可加強通風及陽光直照，令鄰近的建築物更見開揚，加上適當的綠化和外牆物料的選 擇，可改善小區的熱島效應。張冠城又提到：「按元朗區的座向，項目中向南較高的一座可為 較矮的一座遮擋陽光，而早上外置走廊則可阻止陽光直接由東面射入單位，向西的一面亦有結 構牆將陽光阻隔，因此這項目都可算善用了天時地利。」 The wide separation between the two blocks facilitates ventilation in summer time 兩座公屋相距較闊，有助夏天更加通風

Mr Dickson Wat points out that at Phase 3 of Hong Kong Science Park, passive design alone has resulted in energy savings of 16%, which is a very promising start for this energy-efficient development. “The orientation of Phase 3 is different from Phase 1 and 2,” Mr Wat continues. “With major facade facing north and south, the building uses traditional intelligence to avoid the western sun. The surface area of the side facing west has also been greatly reduced; together with an optimised window-to-wall ratio of 40%, this greatly reduces the penetration of solar heat and its impact on the interior of the building.”

The design of Phase 3 also enjoys excellent synergy with the green facilities of Phase 2, such as its Efficient District Cooling System.

After precise calculations during the design process, the cooling load for Phase 3 could be fully met by this system and additional cooling facilities will not be required. The rainwater recycling system in Phase 3 has also been connected to the artificial lake of Phase 2 to collect surplus/overflow water.

This can then be used to irrigate up to the 40% green areas in Phase 3.

Putting People First 以人為本推動綠建 Hysan Place Hysan Place is a commercial building which comprises a shopping mall and office spaces.

For the latter, the team designed a mixed mode ventilation when appropriate, such as during overtime hours. The mall’s rooftop also has an “Urban Farm”, which helps cool the building while also allowing the participants to experience organic farming in the bustling city centre.

Dr Chan says that it is a big challenge to make the building highly environmentallyfriendly, practical and attractive at the same time. To date, the Group's investment in sustainability has won widespread support.

“Tenants of Hysan Place are industry leaders in business and social responsibility,” remarks Dr Chan. “Hysan Place meets their needs in both respects, so the customer response has been very positive.” She also expresses her opinion that ever y green building project has to be designed to suit specific local conditions and that there is no fixed formulato be successful. The most important thing is to carefully study and understand the problems of each project, and then figure out the solutions. At the end of the day, the crux of it all is to promote a green culture and sustainable lifestyle that enables the healthy development of the entire community.

By offering cool air around the bed area, the Peltier Headboard helps reduce the overall cooling of guest room 半導體製冷片冷氣床頭板集中在睡床提供冷氣，減少房間 整體冷氣消耗

Holiday Inn Express Hong Kong SoHo Hotel guests expect to sleep well so they will be ready for the next day’s activities, so it’s vital to make energy-saving decisions that take guests’ comfort into full consideration.

The Holiday Inn Express Hong Kong SoHo features an innovative design of Peltier Headboard. When the system senses a guest is asleep, the headboard will output a slow and comfortable level of air conditioning for the next one to two hours, while the output from the rest of the room’s air-conditioners is reduced. This not only helps guests sleep better, but also saves energy.

“With such a comprehensive green building design, the hotel’s overall electricity savings are above 50%,” says Ir Antonio Chan.

“Achieving a BEAM Plus Platinum rating not only enhances the image of both the hotel and the Group, the hotel also serves as a role model for the industry by showing how energy can be conserved effectively and successfully. We hope projects such as these will attract more participation in the green building industry, for the sake of sustainable development in Hong Kong and around the world.”

香港蘇豪智選假日酒店 酒店是住客每天安睡消除疲勞，為明天做好 準備的地方，因此在節能之餘照顧住客所需 至為重要。香港蘇豪智選假日酒店其中一項 創新設計是半導體製冷片冷氣床頭板。當系 統感應到住客入睡後，床板會於一至兩小時 內輸出舒適的冷氣，同時房間其他部分的冷 氣會減弱，令住客既感舒適，又可節省能源。 陳紫鳴總結經驗指：「綜合酒店各項綠建元 素，整體電費節省超過 50%，酒店取得綠建 環評最終鉑金評級，除提升酒店及集團的形 象外，亦為業界提供節能減排的實例，有助 他們在日後的工程項目中應用。我們希望藉 此吸引更多持份者能參與其中，為香港和地 球可持續發展盡一分力。」

Public estate is home to many people, so its design needs to accommodate a wide variety of needs. Mr Ken Cheung cites the design of the Two-stage Lighting Control System as one example. Public spaces are featured with essential lighting to save electricity, but when needed, a button can be pushed to increase luminosity for the convenience of the elderly or the visually-impaired. This not only saves electricity, but is also a caring feature that benefits the residents who need it most. The project further incorporates a Twin Tank System for its water supply. Studies have shown that this dual-tank design not only helps saving water consumption, but also means that the water supply doesn’t have to be suspended for the whole building when the tank undergoes regular cleaning, thus guaranteeing a consistent supply of water for residents. A truly win-win design!

Mr Cheung believes that the participation of residents and management is indispensable for green buildings such as this. “If only the hardware is incorporated but there is a failure to promote a change of lifestyle to residents, the effectiveness of the features are essentially halved,” he says. “As such, our plan is to distribute a comprehensive green manual to every household describing how to use these facilities. We hope they will understand more how the Housing Authority, its management companies and individual tenants can all work together to make a success of this green concept.”

The Two-stage Lighting Control System enables a flexible lighting in public areas 二段燈光控制節能的設計令公共空間照明更具彈性

By setting up smart meters and “Green Lease” arrangement, the Hong Kong Science Park Phase 3 promotes a green corporate culture among the tenants 科學園第三期將為園內公司設置智能電錶，並訂立「綠色租約」，更進一步推動綠色企業文化

Hong Kong Science Park Phase 3 To encourage energy-saving habits and awareness of companies within the park, Science Park Phase 3 will arrange smart meters for them with the ability to provide real-time statistics of energy consumption.

By separating electricity fees from the management fees, the introduction of smart meter will increase awareness of power consumption and encourage the use of hybrid and natural ventilation system, which will likewise translate into greater energy efficiency and directly benefit all companies.

Phase 3 will also implement a “Green Lease” scheme, actively promoting a green corporate culture. When the site is fully operational, it is expected that the carefully designed green facilities will collectively reduce total annual carbon emissions by about 6,000 tons.

“We are putting particular emphasis on solar photovoltaic systems as one of our key power generation provisions for Phase 3, as we are hoping for the production capacity to provide 1% of total electricity consumption,” explains Mr Dickson Wat. “The long term goal is to utilise them with other systems to ultimately achieve zero carbon emissions.” He adds that the Science Park is committed to releasing data on energy savings and making the public aware of the site’s progress towards its energy-efficiency goals.

A Dialogue on Energy-Saving Technology 機電翹楚 節能技術對談

The “Hong Kong 3030” programme is a key initiative of the Hong Kong Green Building Council (HKGBC). This landmark programme involves striving to reduce the absolute electricity consumption of buildings by 30% of 2005 level by 2030.

We invited Ir Dr Otto Poon, President of the Hong Kong Federation of Electrical and Mechanical Contractors and a renowned expert with half a century’s experience in electrical and mechanical engineering, to provide his analysis of the latest industry trends and eco-friendly energy developments that could shape Hong Kong’s future. 香港綠色建築議會早前提出「香港 3030」計劃，以 2005 年用電量為基準，希望在 2030 年將 建築物耗電量降低三成，因此我們邀得香港機電工程商聯會會長潘樂陶博士工程師，以逾半世紀 機電工程的經驗，分析業內環保節能的趨勢以及香港未來的能源發展。

Feature Interview: Energy

G: GreenMAG

Poon: Ir Dr Otto Poon

G: Do you think the "Hong Kong 3030" programme target set forth by the HKGBC is feasible? How high are its chances of success?

Poon: I think the goal is certainly achievable, especially considering we still have 17 years to reach it. Many areas of technology, r a n g i n g f r o m l i g h t i n g, r e f r i g e r a t i o n and elevators to general energy-saving technology products, have matured considerably in recent years. About 80-90% of electricity consumption in the buildings comes from these areas alone, so the scope for reductions is enormous. Nowadays, we have many types of high-efficiency lamps, and there are many lighting control systems available in the market. Take for example the conference room we are currently in.

There is a small motion-sensing device built at the entrance area. If we stay still for ten minutes, the device will automatically turn off the lights. Many air-conditioner installations are centralised systems, a significant improvement is to change from air-cooled to water-cooled systems. There is now more advanced “maglev” refrigeration equipment, in which the rotating part of the air-conditioner’s compressor is driven by magnetic levitation. This reduces friction during the compressor’s operation, and the energy efficiency can therefore be increased by some 20% . Elevators, too, are now able to convert kinetic energy during their operation into electricity and send it back into the power grid. With such a wide range of technological improvements already available, a 30% reduction in electricity consumption is feasible.

G : G l o b a l l y, “re n ewa b l e e n e rg y ” i s perceived as the solution of choice for energy conservation. What are your views on renewable energy?

Poon: Scientists had stated that the Earth’s ultimate energy source is the sun. Existing natural resources, such as coal, natural gas, petroleum and the like, all came from plants and animals that absorbed the sun’s energy millions of years ago. Interestingly, if we could harness just 2% of the sun’s energy that reaches the Earth’s surface it would be enough to meet all of civilisation’s energy requirements. Currently, in the large

deserts of the United States, Africa, and in the Middle East, there is widespread use of photovoltaic panels to generate electricity.

If transnational electricity grids are used to collect and transmit these renewable energy, it will accelerate its development.

To elaborate further on renewable energy sources, wind and solar energy can complement one another. During the daytime, there is heat and light from the sun. At night, the change of temperature increases the air flow from sea to inland. As such, one can rely on solar power with the use of photovoltaic panels during the day, and then harness wind power at night. If we can develop a system that complementarily generates electricity from both wind and sunlight, we could have more reliable source of renewable energy supply.

G: Do you think Hong Kong has the potential to embrace renewable energy?

Po on: Hong Kong’s first zero - car bon b u i l d i n g, t h e ZC B d e v e l o p e d b y t h e Construction Industry Council, is a very special case in that it simultaneously generates electricity while using it. However, regarding the actual situation in Hong Kong, the potential to use renewable energy sources is rather limited. For example, in a 40-storey building, only 1/40 of the building’s total area is lit by sunlight. Even if that area is packed with photovoltaic panels, it can only be sufficient to generate enough electricity to power the lighting in public areas, thus ultimately rendering it an ineffective and expensive solution.

Take hydrogen cars, for example. The gas cylinders require special protective materials, and additional safety device is necessary. For a hydrogen economy, the world would have to use nuclear power extensively to produce hydrogen. In such a case, consumers could just use nuclear power generated electricity instead, and hydrogen would be unnecessary.

I think the goal of "HK3030" is certainly achievable, especially considering we still have 17 years to reach it. Many areas of technology have matured considerably in recent years.

G : S o m e f o r e i g n co u n t r i e s l o o k t o hydrogen energy for a potential “hydrogen economy”. Do you think this is feasible?

Poon: The hydrogen economy concept is currently most popular in Iceland, where it is fairly successfully applied. The reason it works is because Iceland has lots of geothermal power which can be used to generate the electricity needed to separate water into hydrogen and oxygen molecules.

In other places, this is not an ideal solution.

Pure hydrogen is dangerous to handle, and presents great challenges in terms of storage, transportation, and application.

If we plan for environmental sustainability at the very earliest stages of the project, the cost should not be particularly high, and the payback period can be shortened.

G: So what are the development prospects for the energy we use in Hong Kong?

Poon: For energy development, we need to take a supply and demand perspective and view these aspects separately. On supply side, Hong Kong currently still have some, by present day standard, inefficient powergeneration units, with gas turbines power plants operating at about 45% efficiency, whereas modern technology and new generators can work at 60% efficiency or more. In addition to that, regarding transmission and distribution, there are now power transmission and distribution transformers of higher efficiency, which are designed to minimise the loss of electricity.

If we could construc t our new power plants and properly redesign our power transmission network, combined with the use of the latest technologies, we could increase the efficiency by 15%.

Secondly, on demand side, I’ve already mentioned how lighting and other equipment can improve efficiency. Lots of power consumption actually comes from electric motors. At present, motors are generally at 92-93% efficient, but highperformance motors can work at up to 9798% efficiency. Electric motors are used in a wide range of applications, and so there would be many opportunities to improve efficiency.

GreenMAG

Let’s also consider air-conditioning systems: due to Hong Kong’s humid weather, people require lower temperature conditioned air to feel comfortable. However, there are dehumidifiers that can reduce the humidity of fresh air supply, thus reducing the need for air conditioning capacity to give same feeling of comfort.

G: We have discussed a variety of energysaving technologies. Do you anticipate resistance in their implementation?

Poon: Cost is one of the issues, as the payback period for the implementation of many of these technologies is long. Of course, this depends on the prevailing economic environment and incentives offered. If we follow the Building Energy Codes launched by the Electrical and Mechanical Services Department, and if we plan for environmental sustainability at the very earliest stages of the project, the cost should not be particularly high, and the payback period can be shortened.

On the other hand, for some of the projects in Hong Kong, the safety factor is often set too high. For example, if a building may require 1,000 tonnes of air-conditioning; however, to play it safe, the engineers may use 1,200 tonnes of air-conditioning instead. The capacity of the air-conditioning system will then be larger than necessary.

Unfor tunately, when air- conditioning systems are not used at its optimum design conditions, their output efficiency would become lower.

The research for “Hong Kong 3030” indicates that reductions in energy consumption must not only come from the use of innovative new technologies, but also from people making changes to their everyday habits.

In fact, Ir Dr Poon believes developing good habits is sometimes more important than technology. His company occupies two floors, and he encourages his employees to use the staircase rather than the elevator.

He considers “housekeeping” to be very important, by which he means personal habits such as turning off lights, turning off unused air conditioners, and so forth.

These small changes in daily habits can actually make a big contribution to energy conservation. Thus, while many of us may be fascinated by the development of new energy-saving technologies, we must also remind ourselves to pay attention to the things we do each day and make a personal effort to meet carbon-emission reduction targets.

Feature Interview: Energy G：GreenMAG

潘：潘樂陶博士工程師

G：你認為由香港綠色建築議會推行的「香港 3030」計劃是否可行？成功機會有多高？ 潘：我認為完全可以達到目標，因為還有 17 年的時間，而近年各方面的科技，如照明、 製冷、升降機技術和節能產品，已相當成熟。 其實樓宇在上述幾方面用電最多，佔超過八、 九成。在照明方面，大家都知道電燈效率越 來越高，亦有很多照明控制系統，例如我們 身處的這個會議室，門口有個小小的裝置， 假如我們靜止不動十分鐘，燈就會自動關掉； 空調方面，現已多用中央系統，又由氣冷改 為水冷，最近更有新的「磁浮式」製冷設備， 將壓縮機的旋轉部分以磁浮驅動，減去磨擦 力，能源效益可因此提升約 20%；在升降機 技術上，亦有將升降機運作期間的動能轉化 成電能再供回電網的技術。可見在各種技術 幫助下，應可實現在 2030 年減少 30% 的耗 電量。

另外，風能其實與太陽能可以有相互補助的 作用。白晝陸上受日照氣溫較高，在晚上溫 差會令空氣流動成風，從海面吹向內陸，因 此早上有陽光時可使用光電板，晚上則可依 靠 較 強 的 風 勢。 如 果 有 一 系 統 能 同 時 配 合 「風」和「光」兩大可再生能源，就可加強 穩定性。

G：全球都將使用「可再生能源」視為達致節 能減排的不二之選，你對再生能源的看法如 何？ 潘：有科學家曾說過，地球上最大的能源供 應者是太陽，因為現時使用的煤、天然氣、 石油等，都是億億萬萬年前的植物和動物， 吸收太陽的能量貯存而成。在地球表面，只 用太陽 2% 的能量，就足以滿足人類對電力 的需求。現時，在美國、非洲、中東等地的 沙漠，已有大規模使用光電板發電力。假如 我們有跨國電網收集和傳送這再生能源，就 可促進這方面的發展。

G： 外 國 有 以 氫 氣 作 能 源 的「 氫 經 濟 」 （Hydrogen Economy）一說，你認為可行嗎？ 潘：Hydrogen Economy 現時在冰島最為普及， 亦是一個頗成功的例子，因為冰島蘊含豐富 地熱，可用地熱發電，再用電將水分解為氫 和氧。但在其他地方，這過程效率非常低， 同時氫氣非常危險，於儲存、運輸、使用等 均有難度，例如以氫氣推動的汽車，氣缸須 特別保護，亦要更多安全設備。除非全世界 都改用核能發電，以核電產生氫氣，這就是 一個理想的情況，而一般家用方面因可使用 核電，根本用不着氫氣。

我認為完全可以達到「香港 3030」的目標，因為還有 17 年 的時間，而近年各方面的科技 已相當成熟。

G：你認為可再生能源在香港普及程度如何？ 潘：就本港的可再生能源應用，香港首座零 碳建築物、由建造業議會發展的「零碳天地」 是一個很特別的例子，在用電的同時甚至可 以產生電力。但我認為在香港的實際環境， 再生能源普及程度有限，例如一幢 40 層高的 大廈，經常受日照的面積只佔樓宇總面積的 1/40，即使你用盡這面積放置光電板，產生 的電力可能只夠公眾地方照明之用，效果不 大，成本亦高。

另一方面，部分香港的項目在設計時，安全 系數往往訂得太高，例如某座大廈需要 1,000 噸冷氣，但為保險可能將規格寫至 1,200 噸 而用上較大的設備。當設備未能按設計充分 使用的時候，機組效率便會降低。

如在項目初期做好環保規劃， 成本則不會太高，相信投資回本 期可以縮短。

G：那麼本港節能發展的前景如何？ 潘：針對能源發展，應分開供應及需求兩方 面去看。在供應層面上，現時香港電廠仍有 些以現今標準而言效能較低的發電機組，以 燃氣渦輪推動，效能約為 45%，而現時新的 發電機組整體效能可達 60% 以上。另外，在 輸電及配電方面，現在已有不少高效能的輸 電及配電變壓器，亦可減少能量損耗。我認 為如可興建新電廠和重新設計輸電網絡，並 用上最新技術，效率比現時應可提高 15%。 第二，在需求層面上，剛才提及照明等設備 方面提高效率，但其中耗電量甚大的是電動 機。現時一般電動機效能是 92 至 93%，高 效能的電動機可達 97 至 98%。由於電動機 可用於不同系統，因此受益範圍十分廣泛。 在冷氣系統方面，由於香港天氣潮濕，因此 需要較強勁的冷氣才會感到舒適。我們可在 機組抽入鮮風時先行除濕，就可在減少製冷 量的同時，保持同樣舒適。 G：剛才我們探討的各種節能技術，在推行時 會否有阻力？ 潘：成本是其中一個問題，因相關投資回本 期都比較長，當然亦視乎當時的經濟環境和 提供的誘因。如按照機電工程署《建築物能 源效益守則》，在項目初期做好環保規劃， 成本則不會太高，相信回本期可以縮短。

「香港 3030」的研究顯示，減排成果除由 創新技術帶動外，亦源自我們日常生活習 慣的改變，潘樂陶博士工程師亦認為有時 培養習慣較實際技術更為重要。他的公司 佔地兩層，自己會鼓勵同事來往兩層之間 捨升降機而用樓梯，而他認為更重要的是 「housekeeping」，說的其實就是人的習慣， 出外關燈、關掉不用的空調等，這些習慣 上的改變其實幫助更大。因此，在關注各 種節能技術發展的同時，我們亦要身體力 行，留意生活細節，為減排目標盡一分力。

Modern Waste to Energy Solution for Sustainable Solid Waste Management

that can fill up three Olympic-size swimming pools. The startling waste production rate and limitations in expanding landfill sites mean that we need more effective and sustainable ways to achieve waste reduction.

Incineration: A Current Missing Link

Compared to our counterparts, we are the only place that relies so heavily on landfilling as final disposal means, which is not a sustainable way of waste management.

According to Government's current estimate, the current three strategic landfills in Hong Kong will be exhausted by 2019 the latest.

Hence an incinerator is urgently needed, together with other means for reducing waste, so as to extend the lifetime of our precious landfills. Taipei and South Korea’s experience in particular provide insights for our strategic plan of solid waste management due to similar lifestyle. Both places adopted incineration since mid-90’s to turn waste into energy, thereby reducing waste residues going to the landfills.

he Hong Kong Blueprint for Sustainable Use of Resources 2013-2022 (the Blueprint) recently published by the Environment Bureau aims to develop a comprehensive waste management plan and promote a new social contract with the community to conserve resources and reduce waste. A number of key actions and specific targets for recycling, landfilling and incineration are clearly spelled out in the Blueprint.

Among all these aspects, incineration caused much controversy among the public, yet it is a potential solution for sustainable solid waste management as it can reduce waste significantly as well as turn waste into energy.

Landfilling is the major means of final disposal of the municipal solid waste (MSW) generated in Hong Kong. According to 2011’s figure, MSW takes up 67% of the total waste disposed at Hong Kong’s three strategic landfills while 9,000 tonnes of MSW are being dumped into landfills every day, an amount

Incineration is adopted in many countries and places for decades, but Hong Kong is unique in a way that we have been using landfilling as our final disposal means.

Driving the Turbine: How it is achieved?

A modern incinerator burns waste at high temperature (normally at 850 oC or above) which reduces waste by approximately 90%, as well as generates electricity and low pressure steam at the same time. The daily treatment capacity of a typical waste to energy incineration plant ranges from 100 – 3,000 tonnes. The high temperature exhaust gases from the furnace pass through the waste heat boiler, which generates electricity (through steam turbine) and low pressure steam as renewable energy. By deducting the amount of power required for the operation of the incineration plant, the surplus electricity is normally fed into the power grid and sold to nearby residents.

For a typical waste to energy incinerating plant of approximately 800 tonnes of treatment capacity per day, it can generate tens of million kilowatt hours per year, which can provide electricity for over 10,000 households.

境局最近公佈《香港資源循環 藍圖 2013 - 2022》（藍圖）， 旨在制定全面的廢物管理計 劃，並凝聚社會共識，以達致 減少浪費和節約資源，回收、 堆填及焚化等方案的關鍵措施及目標亦一目 了然。當中垃圾焚化最為大眾關注討論，但 此舉除可顯著減少廢物外，亦可同時產生能 源，實為其中一個可持續固體廢物管理的可 行方案。

垃圾焚化：當前所缺一環 堆填為現時香港處理都市固體廢物的主要方 式。據 2011 年數字顯示，67% 棄置於本港 三個策略性堆填區的廢物為都市固體廢物， 每日數量達 9,000 公噸，足可填滿三個標準 奧運游泳池。驚人的垃圾增長和擴建堆填區 的限制意味着我們需要更有效和可持續的方 式減少廢物。

數十年來，許多國家和地區均已採取焚化作 為處理廢物的方式，唯獨香港仍然沿用垃圾 堆填作最終處理方案。 與其他地區相比，我們是唯一如此倚重以堆 填處理廢物的地方，但此舉非長遠之策。據 政府估計，目前香港三個策略性堆填區最快 將於 2019 年飽和。因此，以垃圾焚化和其 他方式減廢，為我們寶貴的堆填區延長壽命， 已經迫在眉睫。在制定處理固體廢物管理的 策略時，我們可以向生活模式相近的台北市 及韓國借鑑，自九十年代中期以來，兩地均 通過垃圾焚化轉廢為能，以減少堆填的需求。

轉廢為能：如何做到？ 現代的焚化爐會在高溫下燃燒廢物（一般在 850oC 以上），可減少廢物體積約 90%，並 同時產生電力及低壓蒸氣。一般轉廢為能的 焚 化 廠 房 每 日 可 處 理 100 至 3,000 公 噸 廢

A revolving restaurant with a viewing platform built on the chimney of Beitou Refuse Incineration Plant in Taipei is the world's first of its kind 台北北投垃圾焚化廠的煙囪上，設有旋轉餐廳和觀景平台， 為世界首創

物；而高溫的廢氣可透過廢熱鍋爐發電及產 生低壓蒸氣作再生能源。扣除焚化廠房所需 的電力後，剩餘的電力可輸入電網供附近居 民使用。以一般轉廢為能的焚化廠房每日處 理 800 公噸廢物計算，每年可生產數千萬千 瓦小時電力，足夠 10,000 戶家庭正常使用。

Integration with Local Community: A Key to Success A modern incinerator is more than just a solid waste processing facility. It can also serve the community in many other areas.

Apart from providing surplus electricity to nearby residents, the generated low pressure steam is also utilised for green houses, cafés, heated swimming pools and spas, district heating, etc. while some of the facilities are free of charge for the nearby residents to use. In some cases, the incineration plant can become an important landmark of the district as well. For example, at the Beitou Refuse Incineration Plant in Taipei, there are observatory, revolving restaurant and community convention center on the 120m-tall chimney, attracting tourists and visitors.

Still, many people voice out their concerns about the potential health risks generated from the MSW incineration. In fact, the exhaust gases would undergo a series of treatment facilities, such as electrostatic precipitator, selective catalytic reduction, etc., to control the emission of harmful substance like hydrogen chloride, sulphur dioxide and nitrogen oxide, while high temperature inside the incinerator ensures complete destruction of dioxins. Thereafter the cleaned exhaust gases are discharged

at a chimney of typically 100-150m tall, minimising the impact to local residence. In some places, the residues from burning are used as construction materials while most of them will be sent to landfills. Some plants are also equipped with online monitoring equipment on the air monitoring data as well as the amount of generated electricity to increase its transparency to the public.

The emission data for the Tuas South Incineration Plant of Singapore shows a remarkable performance against the limits of relevant regulations, demonstrating the high standard of modern incineration technology in controlling air pollution.

There is no doubt that the modern waste to energy incineration is already a good and mature technology, and it is a direct and effective way to achieve waste sustainability by turning waste to energy for beneficial use and contributing in the overall carbon reduction and many other aspects for the community. Therefore, the next important step is the education and promotion of the successful experience of modern incineration technology around the world, so as to gain public support for building an advanced waste to energy incinerator, which will definitely be a significant part in reaching the waste management targets set in the Blueprint and achieving a more sustainable future for Hong Kong.

融入社區：成功關鍵 現代焚化爐不僅是固體廢物處理設施，更可 在各方面照顧社區所需。除了為附近居民提 供電力外，焚化爐產生的低壓蒸氣更可用於 附近的溫室、咖啡室、恆溫游泳池及水療設 施、區域性暖氣供應等。焚化爐更可以成為 地區重要地標，以台北北投垃圾焚化廠為例， 120 米高的煙囪設有觀景台、旋轉餐廳及社 區中心等，成為當地旅遊景點。 話雖如此，很多人仍擔心焚燒都市固體廢物 影響健康。事實上，垃圾焚化釋出的氣體會 經過一系列處理，如靜電除塵及進行選擇性 催化還原等，以控制氯化氫、二氧化硫及氮 氧化物等有害物質的排放量，而焚化爐的高 溫環境亦能確保完全消滅二噁英。及後，經 淨化的廢氣，通常在 100 至 150 米高的煙囪 排出，以減低對附近民居的影響。焚化後的 殘餘物多數會運往堆填區，部分地區則會用 作建築材料。有部分焚化廠會設有監察裝置， 於網上公布空氣監察數據和所產生的電力， 增加焚化爐對公眾的透明度。新加坡大士南 焚化廠排放數據就法例要求相比下的出色表 現，正正展示現代焚化技術在控制空氣污染 上的高標準。 毫無疑問，現代垃圾焚化轉化能源已是發展 成熟的技術，是直接、有效並可持續的處理 廢物方式，產生能源帶來實際效益之餘，亦 在整體減碳及其他方面貢獻社會。因此，當 務之急是教育和宣傳世界各地成功應用現代 焚化技術的經驗，從而爭取廣大市民支持興 建焚化爐。這肯定是達致藍圖所定的目標， 以及為香港實現可持續未來的關鍵一環。
