2The BEAM 5TH ANNIVERSARY CONFERENCE

Message from Guest of Honour

I am glad to offer my congratulations to the BEAM Society on the successful launch of the 5th Anniversary Conference on Driving for Urban Sustainability.

Promoting green buildings and enhancing building energy saving has been one of the Government’s priority tasks, as over half of Hong Kong’s total energy use is in the form of electricity, and buildings account for 90% of the city’s electricity consumption and about 60% of carbon emission. Since the 1990s, the Government has made considerable efforts in collaboration with building professionals to promote green building and energy efficiency of our built environment. Building on our past achievements in energy saving and taking into account the energy saving potential in the building sector, we published the Energy Saving Plan for Hong Kong’s Built Environment 2015~2025+ in May this year to set the new target of reducing the city’s energy intensity by 40% by 2025 (2005 as the base year). The Plan outlines the policy, strategy, target and key actions that push Hong Kong towards this new energy saving target. In the pursuit of this challenging target, we will join forces with the built environment leaders to accelerate green building adoption in the private sector and mobilise the wider community to act collectively to reduce energy consumption and combat climate change by changing behaviour and adopting green technologies and practices.

Our success in improving building energy efficiency will reveal itself through the reduction in carbon emissions. Following the public consultation on “Hong Kong’s Climate Change Strategy and Action Agenda” Consultation Document, we have set the target of reducing carbon intensity by 50-60% by 2020.

Targeting at the major local emission sources, we have been taking mitigation actions on various fronts, which include revamping fuel mix for electricity generation, maximising energy efficiency, greening road transport, promoting clean fuels for vehicles, and turning waste into energy. On adaptation, the Government has identified eight areas that are more vulnerable to climate change impacts, and have been implementing adaptation measures accordingly.

In witnessing the 5th anniversary of the BEAM Society, I would like to congratulate the successful development of the comprehensive BEAM Plus assessment tools for the unique built environment and climate in Hong Kong. I believe the Society, with its steadfast commitment to continuous improvement and upgrading, will continue to flourish and contribute to the development of an energy wiser, waste less, and more liveable Hong Kong.

I am grateful to the BEAM Society for bringing together experts in Hong Kong and from the Asia Pacific region to share their success stories and the lessons learnt. I wish to express my appreciation for the delegates’ contributions to this conference, and look forward to the insights and new ideas that will emerge from your discussions.

I wish the 5th Anniversary Conference on Driving for Urban Sustainability every success.

Message from BSL Chairperson

The BEAM Society Limited (BSL), which began in 2010, is now commemorating its 5th Anniversary. In real terms, BSL’s history is even longer and richer, as its precursors, the BEAM Society and BEAM Steering Committee, already started providing services 20 years ago. On behalf of BSL, I would like to express my heartfelt gratitude for the wisdom and efforts of all previous committee and board members, and our supporters who have made it possible for us to welcome this day.

To combat climate change and global warming, green building plays a pivotal role to reduce energy consumption and greenhouse gas emissions, while also improving the quality of life and the built environment. Driven by the vision to create a sustainable built environment in harmony with nature, we are deeply committed to improving the quality of Hong Kong’s built environment for a greener, healthier and more sustainable future through the adoption and continual enhancement of our BEAM Plus tools.

To date, with your support, we see that Hong Kong’s top green buildings are now achieving 29% reductions in energy consumption and 39% in water consumption. As of August 2015, over 18.6 million square metres GFA of green building developments had been assessed by BEAM Plus and other BEAM assessment tools. We are proud that BSL is now a highly recognized organization in the benchmarking and assessment of green buildings.

Since 2010, BSL has worked very hard in a massive capacity-building programme for the green building community. Our BEAM Professional Training and Examination and many CPD activities have nurtured a new generation of green building practitioners. There are now over 3,000 BEAM Professionals and BEAM Affiliates, and over 700 registered projects, of which 300 have already been assessed. On a per-capita basis, Hong Kong’s total BEAM-certified area is now more than 2.5m2 per person - a remarkable record that we can all be proud of.

BEAM Plus assessment tools have become the quality label and standards for the building industry and the general public. BEAM Plus provides independent and expert assessment of the sustainability performance of a building with tangible and measurable indicators. These tools, which currently comprise BEAM Plus New Buildings v1.2, BEAM Plus Existing Buildings v.2.0, and BEAM Plus Interiors, have continued to facilitate market transformation. As a non-profit organisation, we are always responsive to the global concerns and the needs of the community. We are very grateful for the support of the Government, and our collaboration with HKGBC, as well as the stakeholders, directors, members, volunteers, staff members and many other good souls who have encouraged us or offered support. It brings me great joy to feel so much positivity and energy supporting us as we sail ahead.

One of our important goals in the near future is to become a public body. While there is a great deal of corporate transformation to be accomplished first, we are hopeful that this will further increase our governance, transparency and credibility. We have also started to introduce the concept of “Better than Yesterday” in our Existing Buildings assessment tool. The major overhaul is to facilitate and allow more flexibility for existing buildings to go green. This will play an ambitious role in helping Hong Kong to transform its large aged building stock through retro-fitting and re-commissioning. This in turn will help to improve the existing built environment and align with the objectives of energy saving, waste reduction, and the creation of a greener and healthier built environment.

BSL is certainly poised to play a significant role in Hong Kong’s transformation to a greener and more sustainable city. Let’s do it together!

Message from organising committee Chairperson

As the Organising Committee Chairperson, it has been my great honour to participate in the anniversary celebrations of the BEAM Society Limited (“BSL”). In recognition of this momentous milestone and the many great things that BSL has accomplished over the last five years, our celebrations have not been limited to a single event, but rather a series of activities that reflect the diverse and ever-growing role of BSL in today’s green building movement. These celebrations commenced with a high-level cocktail reception in April, followed by anniversary-related technical site visits and an intensive training “Comprehensive Certificate Course for BEAM Plus on Indoor Environmental Quality (IEQ) for BEAM practitioners in August, and culminated with a one-day anniversary conference and dinner celebration. This anniversary dinner also offered a fine opportunity to pay tribute to the recipients of our Long Service Awards, namely our BEAM Pioneer and 5-Year Dedication Award. Although not all of these hardworking individuals were able to attend the event, we are deeply grateful for their contribution to both the BEAM Society and BSL.

This varied programme of celebratory activities is richly appropriate when we look back on the many highlights of BSL’s growth in the last five years, and the extraordinary development of BEAM over the last 15 years.

I would like to offer my sincere thanks to all members of the Organising Committee for their valuable contributions and tireless commitment to our work. My special thanks also go to our sponsors and partner organisations for their continuous support. It would be impossible to talk of our accomplishments and celebrations without also mentioning the generous support of the Board, the Marketing Committee and Professional Development Committee. Thanks to the dedication and seamless collaboration between all these parties, we have not only accomplished great things in the past, we are now poised to do even more in the future.

Message from BSL General Manager

It is a source of great joy to me that BEAM Plus is now regarded as the hallmark of building quality in Hong Kong. The remarkable growth of BEAM Plus would not have been possible without the recognition it enjoys from the Government, property developers and stakeholders. I offer my sincere thanks to all those parties for their support thus far. Together, we have created a strong foundation for the future success and sustainability of green building.

As General Manager of the BEAM Society Limited (“BSL”), it has been very satisfying to witness the organisation’s transformation over the last five years. On numerous occasions, I have seen my colleagues successfully turn challenges into opportunities. Thanks to their hard work, we now have a number of exciting new initiatives on the horizon, including the development and implementation of an Electronic Document Management System, and the launch of ISO certification, namely ISO9001, ISO14001 and OHSAS18001. In the months ahead, we will also be undertaking a review to study the feasibility and merits of seeking Charitable Organisation status.

I would especially like to highlight our new membership scheme. In the months and years ahead, BSL will continue to develop and implement platforms that further enhance communication between members and BEAM practitioners. By continually formulating more benefits and privileges for members, BSL is committed to the creation of a dynamic and inspirational community that can meet Hong Kong’s evolving needs long into the future.

I am further proud to report that BSL’s office renovation is on track to achieve BEAM Plus Interiors (BI) certification. This will be an important showcase of the value of BEAM in the renovation of existing buildings, which is a key area of growth in the future.

As BSL moves forward into a new era of growth and success, I want to thank the Hong Kong Green Building Council and the Business Environment Council for the opportunity to collaborate and create new synergies within the green building industry.

I would also like to express my heartfelt thanks to our founding members, and to all past and current chairpersons for their vision and leadership. I likewise offer my deep thanks to our pro bono Directors, Committee Members and Taskforce Members for their leadership and valued input, and our staff for their teamwork, their trust and their enthusiastic response to change. Surrounded and supported by so many talented and generous individuals, BSL can truly face the future with confidence.

ABSTRACTBuilding Sustainability

According to the World Urbanization Prospects 2014, of the 7.2B global population, 3.88B are now residing in cities or urbanized areas. Urban population is projected to grow by 63% to 6.3 billion by 2050. To accommodate the additional 2.46B people, there is a need to build 50,000 flats every day in the next 35 years.

Today, buildings account for 40% of global energy consumption and a third of global greenhouse gas emissions. The Building Sector is pinpointed by the United Nations Environment Programme as having the largest potential for long-term and cost-effective reduction in greenhouse gas emissions. As such, the speaker attempts to illustrate with a conversion project to demonstrate how an existing building could remain not only green and sustainable but also a showcase through transformation, continuous evolution and integrating with community over time.

ABSTRACTChallenges and Benefits of BEAM Plus Existing Tools The Building Environmental Assessment Method (BEAM), developed and owned by the BEAM Society Limited was first initiated in 1996. After more than a decade of implementation, BEAM has developed as one of the world’s leading green building assessment scheme, incorporating a wide range of sustainability issues over the life-cycle of a building.In response to the global environmental issues of climate change and global warming, various BEAM Plus assessment tools covering all scales and types of buildings were being introduced in 2010. The latest versions of BEAM assessment tools are currently the BEAM Plus New Buildings version 1.2, BEAM Plus Existing Buildings version 1.2 and BEAM Plus Interiors version 1.0. These different versions of the BEAM Plus rating system have long been used in the private and public sectors during the design, construction and operation management.BEAM Plus was recognized by the HKGBC as Hong Kong’s green building rating system. Since April 2011, it has also been adopted as a pre-requisite by the HKSAR for granting a gross floor area concession in the building construction as an incentive to adopt green initiatives through BEAM Plus. Over the years, a total of 663 projects have been registered for BEAM Plus in which over 200 landmark projects encompassing over 18.6 million square meters of space has been certified.Project statistics analysis of all the submissions has revealed that a large variety of building types, including residential, commercial, GIC and industrial are able to achieve the upmost Platinum rating. The social benefits offered from these projects include minimized adverse environmental impacts during construction and operation, achieved lower-than-average energy and water use, ensured a quality and healthy indoor environment; innovative features such as the use of bio-diesel in power generation, radiant cooling and peltier bed coolers, Building Information Modelling (BIM) to optimise material use, etc. were developed.While appreciated the success of these BEAM Plus projects, there are yet many challenges to face with, such as keeping the time pledge in assessment, maintaining impartiality, consistency and transparency within the industry and continuous improvement to keep in pace with the market and international standards.With the commitment to develop high standard of green building practices, a number of major tools, such as the BEAM Plus Existing Buildings, are currently undergoing major revamp which will be ready to launch soon. The BEAM Plus New Buildings tool review has scheduled to complete in 2016 and a new scheme on neighbourhood is under active development.

Speakers


Carlos is the Program Manager at the National Australian Built Environment Rating System (NABERS). He is responsible for all aspects of the delivery of the NABERS program, Australia’s most successful building sustainability rating system. NABERS has been instrumental in a profound transformation which has seen the Australian commercial building sector to become one of the world leaders in sustainability over the last decade.

Carlos was until recently the Manager for Development and Innovation at NABERS, leading the development of new NABERS tools and major technical revisions to existing tools. In that role, he led the re-development of the NABERS tool for shopping centres, which has since been enthusiastically adopted by most major shopping centre companies in Australia to measure their energy and water performance. He also led the re-launch of NABERS Indoor Environment, a world’s first measurement-based Indoor Environment Quality rating system for buildings.

Carlos was born and raised in Chile, he studied in South America and Europe, and now lives in Sydney, Australia. He is a Mechanical Engineer by trade, a Fellow of Australia’s Centre for Sustainability Leadership and a regular speaker at sustainability conferences in Australia and overseas.

ABSTRACTThe Green Shift: How Australian Commercial Buildings Became World Leaders in Sustainability

In the early 2000’s, the commercial property sector in Australia was affected by many of the common barriers to sustainability. The environmental performance of buildings was a low priority for property companies, and progress in the sector was slow.

A decade later, sustainability has become an integral part of those very same companies, who are now engaged in an all-out race to outperform each other in the sustainability front. The Australian property sector now leads the world in the Global Real Estate Sustainability Benchmark (GRESB) and its commercial buildings are reducing energy use at one of the fastest rates in the world.

How did this dramatic change occur, and why?

In this presentation, Mr. Flores explores some of the specific government policies, social circumstances and market mechanisms that allowed for such rapid change. The presentation will also introduce the National Australian Built Environment Rating System (NABERS), the government-run sustainability rating scheme at the very centre of this green shift.

ABSTRACTA Decade of CASBEE towards Holistic Sustainable Built-Environment

Ten years have passed since the first official edition of Comprehensive Assessment

System for Built Environment Efficiency (CASBEE) for New Construction of Buildings was released in Japan in 2003 after the elaborate preparation. It was made possible through the collaboration of academia, industry and national and local governments, which established the Japan Sustainable Building Consortium (JSBC) under the auspice of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

During this decade, much efforts have been made by a great number of related experts including myself to develop a holistic, cross-scale approach to environmental performance assessment that includes a number of new conceptual underpinnings and approaches. From the very beginning, CASBEE has been designed to both enhance the quality of people’s lives and to reduce the life-cycle resource use and environmental loads associated with the built environment, from a single home to a whole city.

Consequently, a variety of CASBEE schemes are now deployed all over Japan and supported by national and local governments. While specific innovative aspects of CASBEE have been internationally acknowledged and referenced, JSBC was encouraged to contribute to sharing its concept and methods through publicity and workshops.

Along with the zeitgeist and the consequent change of social, industrial and political requirements, CASBEE has been responding and developing accordingly. Specifically it allowed to develop associated assessment tools of the built environment of not only a single building but also a group of buildings (i.e. neighborhood or district) and even a whole city bounced by administrative boundaries. CASBEE family of tools therefore include now CASBEE-District and CASBEE-City, which are currently used to evaluate and compare the relevant governmental policies. Recently, it is further developed to assess a whole nation using common data worldwide available.

My presentation will be focused on those latest outcomes of CASBEE development in accordance with the Conference’s theme ‘Driving for Urban Sustainability.’

ABSTRACTSingapore’s Green Building Masterplans and the Importance of Measurement, Verification and Ensuring Continuing Performance

Singapore has targeted to green at least 80% of her building stock by 2030. To achieve this ambitious goal, the Building and Construction Authority (BCA) launched three Green Building Masterplans in 2006 and 2009 and 2014 respectively. The first Masterplan was aimed at promoting environmental sustainability in new buildings. The second Masterplan targeted the large stock of existing buildings.

Last year, BCA launched the 3rd Green Building Masterplan which will take Singapore’s greening efforts beyond the building structures and hardware, to focus more on end-users. It aims to create a paradigm shift in our behaviour and practices. It also targets to improve the environment we live, work and play in, so as to create a positive impact on our health and well-being.

This presentation will report on the progress of key initiatives in the third Green Building Masterplan. It will highlight the new Green Mark 2015-BCA’s new environmental rating system for the built environment, building upon the 10 years and close to 2,300 Green Mark Building projects. It will also discuss the importance of ensuring the green buildings’ continuing performance, how this is accomplished through measurements and verification (as part of the certification process) and legislations mandating minimum system energy efficiency standards, compulsory energy audits and disclosure/reporting of building energy performances by building owners and utility companies.

ABSTRACTParadigm Shift for Existing Buildings towards Sustainability

The BEAM Plus Assessment Tools have been working towards a more sustainable built environment in Hong Kong since its establishment in 1996. Being one of the world’s leading green building assessment systems, BEAM Plus continues to evolve to incorporate a wide range of sustainability issues and embrace the latest standards in defining the overall quality of a building.

While much of the focus and attention of the green building has been made on driving sustainability in new buildings, the majority of building stock exists in the city are over thirty years old. Therefore, it is clear that retrofitting and recommissioning of existing buildings can play a significant role in the world of sustainability.

The latest development in BEAM Plus Existing Buildings (EB) aims for a paradigm shift towards sustainability. To improve the energy efficiency and environmental performance of existing buildings, BEAM Plus has taken the initiative to echo with the government’s latest target under the “Energy Saving Plan (ESP) for Hong Kong 2015 – 2025+”. Apart from energy saving, the key priorities will be the moulding of inhabitant’s behaviour lifestyle through demand-side management together with the enhancement to aged building design.

In response to the ESP, BEAM Plus existing building tool attempted to embrace existing buildings of all ages. Various levels of practical requirements and flexible implementation options are available in the new tool to encourage participation.

The revamped tool has undergone a thorough studies and with wide coverage of stakeholder engagement feedbacks to closely cope with the local climatic and physical constraints and ease of long-term facility management. The new feature built in this EB tool is rather unique as compared with the similar tools in other countries which may be able to set precedent to promote sustainability in high density living. However, appropriate incentive formulation to attract various stakeholders is yet to be the most challenging exercise to put this initiative into real action. In addition, public education is another issue as awareness and participation of the general public are equally important to the EB assessment tool. Increase in public awareness will certainly benefit the users and the society as a whole.

ABSTRACTImplementation, Challenges and Benefits of Revamped Tools

BEAM Plus Existing Buildings (EB) provides building users with a single performance label that demonstrates the overall quality of a building that is already in use. A preliminary study on the major issues of BEAM Plus conducted by the HKGBC, have revealed some credit items in BEAM Plus EB v1.2 might require modification as well as a number of opinions that stakeholders expressed concerning the scheme. This gave birth to the revamped tools of BEAM Plus EB.

Aiming to increase the participation rate while maintaining the function of the rating tool in defining green buildings, other similar schemes in the world were referenced, and the revamped tools were designed to serve EBs with and without BEAM certificates. Apart from the conventional comprehensive scheme which is designed for buildings with BEAM Plus certificate, a selective scheme was also developed for existing buildings that need time and budgets to upgrade its building services system and develop its operational management system.

The new BEAM Plus EB tools are designed to have a clear relationship with statutory requirements, strong synergy with other environmental award or certification schemes, and incorporated the building energy performance benchmarking tool and the Hong Kong Green Building Council Green Product Accreditation and Standards.

The revamped EB tools echo with the latest government policies on green building and energy saving, and play an important role in HKGBC’s electricity reduction campaign “HK3030” and the whole green building movement. The stepwise improvements in EBs and management practices that induce behavioural changes are rewarded in order to encourage a wide up-take in the territory. The clear progression ladder presented could attract continual improvements in long term.

FULL PAPER

CHALLENGES AND BENEFITS OF BEAM PLUS EXISTING TOOLS IntroductionThe Building Environmental Assessment Method (BEAM) is Hong Kong’s locally produced green building rating tool. Developed and owned by the BEAM Society Limited, BEAM began operation in 1996. After more than a decade of implementation, BEAM has developed as one of the world’s leading green building assessment scheme.

It embraces a comprehensive range of standards and practices in assessing, improving and certifying the overall quality of a building. Similar to other worldwide green building assessment tools, BEAM incorporated a wide range of sustainability issues with proper consideration of the local, regional and global environmental impact which seeks to measure, improve and label the performance of buildings over their life-cycle with integration of over 100 good practices in planning, design, construction, commissioning, management, operation and maintenance.

Since the establishment of BEAM in 1996, it has undergone a number of revisions to embrace the latest standards. The general direction of changes were: from narrow to wide applicability; from prescriptive to more performance-based; from a narrow scope to increased comprehensiveness; from emphasising indoor environmental quality only to demanding a balanced achievement in wider range of aspects; and last but not least, from relying on active systems to encouraging passive design.

This paper will look at how the BEAM rating tool has grown and matured over the years, its present status and future outlook.

An Early StartThe Buildings in Hong Kong are featured by their high-rise and high-density throughout the territory. The design and operation of these buildings play a significant role in the region’s environmental footprint as well as the lives and well-being of the citizens. Globally, buildings account for about one third of the world’s greenhouse gas emissions. However, in service-based economies such as Hong Kong, the figure is close to 60%.

In 1995, two local property developers, HongKong Land and Swire Properties, conceived an idea of developing a Building Environmental Assessment Method (BEAM) with the belief that the industry should take the lead to tackle environmental issues instead of waiting for legislation. BEAM Steering Group was formed by the Real Estate Developers Association of Hong Kong, Planning Environment and Lands Bureau, Swire Properties, HongKong Land, Hong Kong Polytechnic University and Business Environment Council.

The first BEAM manual in 1996 comprised two versions, one covering new office buildings and the other for existing office buildings. The primary aim of this rating tool was to reduce the environmental impact of buildings using the best available techniques and within reasonable additional cost. The major issues addressed were ozone depletion, recycling, greenhouse gas emission and indoor air quality.

The Pioneer High-rise Residential SchemeFollowing the first version, it was decided to extend the scheme to high-rise residential buildings – the first assessment system of its kind in the world. The second generation of BEAM was launched in 1999 that featured an additional rating tool for new residential buildings. The two office building standards were updated at the same time. The revisions made included the removal of Overall Thermal Transfer Value (OTTV) assessment and the transferal of the original credits to the electricity use on air-conditioning for deep plan office buildings, internal heat gain, rather than envelope load, usually dominated the cooling load. Focusing on overall kWh/m2/year instead of OTTV also allowed flexibility in design by allowing a trade-off between the envelope performance and the energy efficiency of air-conditioning system. The Global, Local and Indoor issues were also expanded. There was a broadening of the scope to encompass other greenhouse gas related aspects such as limitation of private car parking spaces and encouraging natural clothes drying facilities. Areas specific to the needs of Hong Kong were also covered, including the proper location of domestic air-conditioning units and proper noise control in a high-density living environment. The value of environmental management plan and ecological impact assessment had also been recognised.

FULL PAPER

Significant UpgradeWith the success of assessment in new and existing offices and residential buildings, other projects including schools, hotels and shopping malls, etc. began to be proposed for assessment. Encouraged by the market demand, the third generation of the BEAM rating tool was compiled and issued in May 2003. This represented a significant upgrade by broadening the types of buildings that could be assessed. The schemes were renamed to “Existing Buildings” and “New buildings” without restriction to offices and residential types. Besides, the number of best practice criteria was increased to over 100, covering areas specific to the high-rise and high-density environment of Hong Kong, including off-site prefabrication and mechanised construction, embodied energy of structural materials and mitigation of urban heat island effect.

The assessment credits were grouped into six categories: Site Aspects (SA), Materials Aspects (MA), Energy Use (EU), Water Use (WU), Indoor Environmental Quality (IEQ), Innovations and Performance Enhancements (IA). This laid down a foundation skeleton for the BEAM standard.

More importantly, the energy assessment criterion was migrated from kWh/m2/year to percentage gained using the energy budget approach which could be applied to a much wider range of buildings. The new version was based on the aggregated annual energy use by all the systems which enhanced design flexibility. The Assessment was very similar to the method used in performance-based building energy code (PBEC), but PBEC was a pass/fail assessment whereas BEAM quantified the level of improvement and also included an assessment of the peak electricity demand. The method could also be applied to mixed-use buildings which were dealt with by an area weighting method. This placed the tool in a good position to assess multi-use complex buildings in Hong Kong.

Increasing Comprehensiveness – version 4/04 & 5/04After pilot-project testing, further review and development in December 2004, a set of fine-tuned versions known as the 4/04 Version for New Buildings and 5/04 Version for Existing Buildings finally emerged. These versions extended the coverage to issues that further defined building quality and sustainability, including enhanced hygiene requirements with lessons learnt from SARS outbreak, security and amenities provisions, universal access and cultural heritage. In this way, BEAM provided users with a single label that demonstrated the overall building performance.

Enhancing the Chosen SchemeWhile BEAM was a private sector initiative, the Government was also enthusiastic in promoting green building. After conducting a holistic review to determine the way forward, it was recommended the adoption of BEAM as the integrated model for green building assessment in Hong Kong. The BEAM Society took up the development work and in 2010, BEAM Plus version 1.1 was introduced in response to the global environmental issues of climate change and global warming to meet higher expectations for the public and community. The major changes included:

1. A new type of credits – prerequisite credits were added in the scheme. All participating buildings should fulfil these credits first in order to proceed to the remaining part of the assessment. The purpose was to clearly define the bottom line for every green building.

2. In view of the increased importance of microclimate in a high-density city, Air Ventilation Assessment (AVA) was added to the rating tool to encourage developers to optimise the layout of their buildings.

3. To reduce carbon emissions, regionally manufactured materials were encouraged.

4. To encourage good architectural planning and passive design, a new credit known as “energy efficient building layout” was added. This included building orientation, site permeability, solar shading, OTTV and vertical daylight factors.

5. Multiplier type weighting factors were introduced to precisely enforce the relative importance of the five aspects: SA, MA, EU, WU and IEQ. In particular, EU was given a higher weighting factor (35%) in response to global concern on climate change and carbon emissions. In the past versions, the relative importance of EU (as counted by the number of credits) used to be around 25-28%.

6. Minimum score requirements were imposed on EU and SA. In the past, only IEQ had such a requirement.

7. For renewable energy system installation, the assessment scale was adjusted and an alternative way of assessment based on the percentage of building footprint covered was added to provide more incentives for applicants to pursue these credits.

In April 2010, the Hong Kong Green Building Council (HKGBC) endorsed the BEAM Plus scheme as the officially recognised green building rating tool in Hong Kong. In August 2010, project registration for the scheme commenced. The scheme operation was taken up by HKGBC while the actual assessment work was entrusted by HKGBC to BEAM Society.


FULL PAPER

One year after the promulgation of BEAM Plus, the HKSAR Government decided to give the green building movement a bigger push. Starting from 1 April 2011, participation in BEAM Plus in addition to Sustainable Building Design Guidelines (SBD Guidelines) shall be one of the prerequisites for private developments to obtain gross floor area (GFA) concessions for green/amenity features and non-mandatory plant rooms.

Encouraging Passive DesignThe latest version of BEAM Plus Version 1.2 was launched in 2012 which included BEAM Plus for New Buildings (NB) and BEAM Plus for Existing Buildings (EB). It was developed in response to stakeholder engagement which brings together a holistic component of Passive Design for residential development as an alternative method of assessment.

With widespread use of BEAM Plus in the industry, there was feedback that criticised the inadequate weight of passive design in the rating tool. Passive design is one major design approach for buildings as it enables a building to respond to the local climate and reduce reliance on active systems which in turn reduce energy consumption. The ultimate goal of passive design is to completely eliminate the use of active systems while maintaining occupant comfort. Although it is unlikely that such a goal could be achieved under the hot and humid climate of Hong Kong, passive design should still be encouraged, especially for residential buildings, in order to rationalise the building design strategy and to improve building performance.

Expanding to Interiors & Neighbourhood DevelopmentWhile the incorporation of passive design in 2012 was a great improvement to the building design approach, the HKGBC and BEAM Society Ltd were not complacent with this achievement. In 2013, the two organisations launched a new rating tool for building interiors – BEAM Plus Interiors (BI). Non-domestic tenants and occupiers now have a blueprint for creating an environmentally friendly and healthy interior. The BI tool complements the two organisations’ successful BEAM Plus New Buildings by certifying an area of facility design not adequately covered by the previous tools.

A new scheme of BEAM Plus Communities/Neighbourhood Development is under development by the Hong Kong Green Building Council (HKGBC) to embrace public realm and incorporate community elements beyond buildings.

BEAM Plus Assessment AspectsA certified BEAM building is safer, healthier, more comfortable, more functional and energy-efficient than a similar non-certified building. The BEAM scheme signifies a building quality in a holistic approach with the following six key attributes:

1. Site Aspects – land use and location, site layout optimisation, transportation, accessibility, ecology, amenity, site and neighbourhood interfaces, site emissions and management, etc.

2. Material Aspects – optimisation in design and operation, innovative construction methods, building flexibility and durability, the avoidance of environment-damaging materials, waste minimisation, etc.

3. Energy Use – passive/low-energy design, microclimate, plant/equipment efficiency, renewable energy, annual energy consumption reduction, etc.

4. Water Use – potable water quality, water economy and recycling, and effluent management, etc.

5. Indoor Environmental Quality – safety, security, hygiene, amenities thermal comfort, ventilation effectiveness, indoor air quality (internal and external pollutants), natural/artificial lighting, acoustics and vibration, etc.

6. Innovation and Additions – innovative techniques and enhancements beyond those stipulated in the BEAM criteria indicated above

Achievements of BEAM Plus BEAM Plus assessment can be applied to all types of new and existing buildings, including residential, commercial, institutional, industrial, hotels and mixed complexes etc. The latest statistics reveals that over 200 landmark projects encompassing over 18.6 million square meters of space achieved the BEAM Plus Label.

As of August 2015, a total of 690 projects has been registered for BEAM Plus assessment. Residential building constitutes to the largest proportion of 42.8 percent. The second major category is commercial building which amounts to 16.7 percent. The Government buildings and mixed use also make up 16.6% and 12.2% respectively. A small proportion is from institutional, industrial and hotel.

For completed projects, there was a total of 310 projects completed in PA stage as of August 2015. Among which 46.2% are residential buildings, 19.7% is commercial buildings and the rest are from Government buildings, hotels, mixed use premises.

Future Development of BEAM PlusLooking forward to the future, it is expected that the BEAM Plus rating tool would continue to enhance its comprehensiveness by incorporating more sustainability elements, keep in pace with the industry advancement through partnership of stakeholders in the building industry and continue to develop high standard of building practices.

In 2014, a major revamp for the latest version of BEAM Plus Existing Buildings (EB) version 1.2 was carried out in response to the relative low participation rate. Experts and stakeholders are engaged in evaluating and formulating refinement recommendations. The official publication of the revised tool is expected to be launched in September 2015.

To embrace the latest standards and government regulations, another major revision is currently undergoing for the BEAM Plus New Buildings (NB) version 1.2 and is expected to be published in 2017. The key area of revision include:

1. Enhancement of existing credit requirement

2. Review on the framework and grading methodology

3. New initiatives/new ideas

The revamp will be tailor-made and optimised for Hong Kong situation while experience of other worldwide schemes will be taking into account, such as China-Three Star, Singapore-Green Mark, Japan-CASBEE, Australia-Green Star, UK-BREEAM and USA-LEED. In addition, it will explore the incorporation of health and well-being and embrace latest standards or technologies in the industry. For example, the Green Product Labelling and Carbon Labelling Scheme.

The release of Energy Saving Plan 2015-2025 (ESP) in May this year will also be a major element that we need to take note of, especially on how we can incorporate Government’s policy and strategy into our next version of BEAM Plus NB tool.

ESP targets to achieve energy intensity reduction by 40% by 2025 using 2005 as the base through the combination of educational, social, economic and regulatory means. Both public and private sectors will play an important role towards the success of meeting the ESP target. Government and public sector will take the lead and set example while private sector will focus on potential gains in new and existing buildings. Alternatively, public and private sector can partnership to enable the Energy Wise transformation through collaborative effort.

ConclusionFrom 1996 to the present, the BEAM/BEAM Plus rating tool has certified more than 18.6 million square meters of GFA. With years’ experience of operation and fine-tuning, BEAM Plus can serve as a good role for other high-rise, high-density building developments in the sub-tropical climate. In the local context, the scheme will continue to transform the way we construct and operate for a better living environment.
