4 Zero Carbon Partnership Workshop Report About The Hong Kong Zero Carbon Partnership The zero carbon building approach has been adopted in many countries and regions as an important government strategy for addressing climate change, achieving a low carbon economy and uplifting quality of people s life. Zero carbon buildings are far more than a technological solution, but complex socio-technical systems. It is therefore important to enhance public and stakeholder engagement in the planning and delivery of zero carbon buildings. However, how stakeholders can work in partnership for delivering zero carbon buildings effectively remains a socio-technical challenge. The Hong Kong Zero Carbon Partnership is a research initiative funded by the Construction Industry Council (CIC) and led by The University of Hong Kong (HKU) with support from a number of organizations including Zero Carbon Building (ZCB), Hong Kong Housing Authority (HKHA), Hong Kong Green Building Council (HKGBC), China Trend Building Press, Pennsylvania State University, and Zero Carbon Hub. The Partnership aims to function as a mechanism to bridge the links between the public and many stakeholder groups in Hong Kong and beyond, and provide a platform to support the transition of the buildings and the built environment in Hong Kong towards zero carbon and sustainability. Supporting the Partnership is the Hong Kong Zero Carbon Portal with measurement and monitoring of Hong Kong s public and stakeholders understanding, attitude and behaviour regarding zero carbon building. The Partnership and its supporting Portal are expected to be sustained through a CIC-HKU joint force after the project is completed for the benefits of the industry and society. 1

5 About The Workshop Series The workshop series are an important part of the research initiative on which the Hong Kong Zero Carbon Partnership is based. The workshops are planned to be organized in alignment with the seminar series to ensure the progressively enhancement of the public and stakeholders understanding of zero carbon buildings. The workshops thus mainly target the public and stakeholders within Hong Kong. The learning of the principles, practices, policies and priorities of low or zero carbon building through the workshops will help with the development of strategies for achieving zero carbon buildings. Such strategies will cover the aspects of user behaviour, building energy efficiency, on-site renewable energy technologies, and energy production and supply. 2

18 Zero Carbon Partnership Workshop Report Interfacing the Virtual and the Real in Product and Process Modeling of Whole Building Energy Performance Prof Khee Poh Lam Carnegie Mellon University, US Bio Prof Khee Poh Lam is an educator, researcher, architect and consultant who is specialized in life cycle building information modeling and computational design support systems for total building performance analysis and building diagnostics. He has completed many major funded research projects and his work has been widely published. He serves on the inaugural Editorial Boards of the Journal of Building Performance Simulation and Building Simulation: An International Journal. Prof Lam is a member of the Energy Foundation Board of Directors. He actively works with the EF China program on a range of activities including green building codes and standards, education and training, as well as sustainable design demonstration projects in China. He is also a former Board member of the Global Buildings Performance Network (GBPN) that assists governments and industry policy makers to identify, adapt and implement policy best practices for low-energy, affordable and healthy buildings, contributing to low carbon and resilient cities. 15 Prof Khee Poh Lam delivered a speech on interfacing the virtual and the real in building energy modeling. At the beginning, he explained the input factors of building energy modeling and the relevant output data. The gaps of adopting the output data in practice or academia were identified. Prof Lam then elaborated on the steps of integrating building data with critical analytics and interfaces for a high performance built environment. Firstly, regarding the intelligent data for corporate and campus portfolio managers, by monitoring and analyzing a portfolio of all corporate buildings with real-time utilities and building automation, it is possible to track the potential problems and find out the opportunities for improvement in energy performance. Secondly, in order to make the data accessible to facility managers and the public, intelligent dashboard has been used to showcase the real-time IEQ status, electrical/ gas trending and energy consumption maps, with which smart control of the building energy performance can be manipulated by the managers. Thirdly, with regard to the intelligent data for occupants with individualized plug load meter/controllers, it has been found that different intervention approaches during the building operation process contribute to varying degrees of energy saving, within which the combination of feedback, control and automation performs the best. Finally, Prof Lam engaged one of his research students, Adrian Chong, over Skype, who illustrated how to estimate missing value for building sensor data via support vector machines.

28 Zero Carbon Partnership Workshop Report Policies and Industry Engagement for Zero Carbon and Low Energy Buildings: UK Experience Mr Rob Pannell Managing Director, Zero Carbon Hub, UK Bio Mr Rob Pannell is Managing Director of the Zero Carbon Hub, a role to which he brings a wide range of knowledge regarding sustainability, innovations, technology prototypes, trials and solutions. This knowledge is a crucial asset for both the Zero Carbon Hub and UK government, with Mr Pannell working closely with ministers and senior civil servants to advise on key risk areas around the design and construction of low energy buildings and European and UK policy development. Prior to joining the Zero Carbon Hub, Mr Pannell was a senior figure in the construction industry with over 35 years of experience with Taylor Wimpey UK Ltd. where he held a series of senior level roles, most recently as UK Director of Production (construction and design). Within this position Mr Pannell investigated and established a cost base and technical compliance of practical renewable energy and building fabric solutions to meet the various UK government policies. Mr Rob Pannell shared with the audience UK s experience with policies and industry engagement for zero carbon and low energy buildings. He first introduced the role and functions of the Zero Carbon Hub that the Hub facilitates the mainstream delivery of low and zero carbon homes in the UK. Mr Pannell then provided an outline of both the UK s and the international context of the actions in response to climate change. Regarding the policy on building energy/carbon performance, Mr Pannell compared the disparate objectives between the European and the UK context, to show that zero energy/carbon is a great challenge for all of the countries. He emphasized the consequences of the performance gap and outlined the UK ambition on closing the performance gap that from 2020 at least 90% of all new homes meet or perform better than the designed energy/carbon performance. The issues of ventilation, overheating and industry engagement were addressed as well. 25

38 Zero Carbon Partnership Workshop Report Integrated Approach to Building Carbon Emissions Reductions in Hong Kong Mr M.K. Leung Director, Ronald Lu & Partners, Hong Kong Bio Mr M.K. Leung is the laureate of the inaugural Singapore Institute of Architects Uniseal G-Architect Award 2014 and is well recognized locally and internationally for his specialized knowledge and integrated design skills in sustainable building design. His diverse portfolio comprise high-performance new buildings adopting a humane, ecologically-centric approach, green retrofit of existing buildings, sustainability master planning and research. His award-winning projects include the first zero carbon building in Hong Kong, a community-centric vertical green campus for the Technological and Higher Education Institute of Hong Kong, the pioneering sustainability master planning for Hong Kong Science Park Phase 3, the Transformation of the existing Jockey Club Environmental Building into a Centre of Excellence in Sustainability, and a number of research studies related to sustainable design such as the formulation of the new BEAM Plus Neighbourhood certification tool and the Study for Design and Construction Requirements for Residential Buildings for Energy Efficiency. He has been active in academic and professional circles related to the issue of building performance, energy efficient building design and green architecture. 35 Mr M.K. Leung, Director of Ronald Lu & Partners, shared an architect s perspective on an integrated people-oriented approach to building carbon emissions reductions in Hong Kong. By questioning why it is not effective to focus on energy saving alone, Mr Leung argued that energy saving has to be considered together with a number of people-oriented issues. Since the electricity tariff of Hong Kong is relatively low, it is hard to propose reasonable payback periods for advanced green building systems to clients and developers. While corporate social responsibility was found to be not that important to clients and developers, low carbon development tended to depend on the extent to which Hong Kong people are environmentally driven. Mr Leung then explained the concept of integrated and people-oriented design, which involved balanced consideration of energy, carbon footprint and life cycle cost, comfort, health and well-being, beauty in addition to other spatial, functional issues and requested contributions from multidisciplines. Mr Leung finally presented several project case studies to demonstrate the principles of adaptability, climate responsiveness, wellness and smartness with regard to how architects practice integrated design towards zero carbon.

49 Plenary Session and Closing Remarks Prof Khee Poh Lam, Mr Rob Pannell, Mr M.K. Leung and Dr Wei Pan joined the plenary session. A number of questions and comments were raised by the audience. Common themes of the plenary session included the need for adopting the socio-technical approach to reducing energy consumption and carbon emissions of buildings particularly in the high-density high-rise urban contexts and the importance of behavioural changes to the achievement of building towards zero carbon. Dr Wei Pan delivered the closing remarks. He first summarized the presentations delivered by the invited local and overseas speakers and thanked all for sharing their knowledge and experience in various topics of low or zero carbon building. He then highlighted the significant challenge for delivering buildings towards zero carbon in Hong Kong as a typical high-density hot-and-humid urban environment. The HKZCP provides a platform to support knowledge sharing, stakeholder engagement and behavioural changes. With the proactive participation of the public and wideranging stakeholders, the Partnership should enable a step change in the Hong Kong society and industry towards zero carbon building. Dr Pan finally thanked all attendees for their participation in the workshop, and invited all for continuous support for the research activities and events of the Partnership in the future.
