Executive Summary About 200 people participated in a forum called “Less than Zero – The Future for Buildings & Carbon Emission?” organized by Civic Exchange and sponsored by the German Consulate in Hong Kong on 1 November 2011. The forum explored the concept of zero emissions buildings and “plus energy” buildings, which generate more energy than they consume. These issues were discussed with the help of international and local experts, including: Mr Werner Hans Lauk – Consul-General of the Federal Republic of Germany to Hong Kong, who welcomed participants and provided the context of Germany’s commitment to climate action and the creation of a low carbon economy. Dr Rüdiger Kratzenberg – Head of the Building & Construction Industry, Directorate of Germany’s Federal Ministry of Transport, Building and Urban Development. In a presentation entitled “Buildings as Power Plants”, Dr Kratzenberg outlined Germany’s continuing efforts at improving energy efficiency in buildings, and discussed the interrelationship of research, guidelines, and regulations. He showcased several examples of “plus energy” houses developed by universities in Germany, which combine integral energy efficiency with technologies for generating renewable energy. The surplus energy is earmarked for charging an electric car, thus combining housing and mobility in the same energy story. Mr David Littler - Group Director of the Building Services and Sustainable Engineering group in the Hong Kong office of Buro Happold. Mr Littler examined different sustainability measurement tools that are being used across the world. He compared the different priorities of these tools, noting the emphasis the German system (DGNB) places on operations and ongoing maintenance throughout the building life-cycle. He introduced a framework he called “Lean, Mean, Green” to tackle energy use and carbon emissions by looking at the energy or carbon reductions per dollar of intervention. Under this approach, the first focus should be on design of the building (“Lean”), then the systems within the building (“Mean”), and lastly the use of renewable energy (“Green”). Dr Raymond Yau – Arup Fellow, Director of Arup Hong Kong. Dr Yau presented on the practice and challenges for zero carbon building in Hong Kong, summarizing the policy background for climate action in Hong Kong, as well as the scale of the challenge. He described the proposal for the development of the West Kowloon Cultural District along zero emissions principles. He outlined a series of measures that are needed to set Hong Kong on a faster track to reduce carbon emissions, as well as commenting on a range of issues, such as legislation, feed-in tariffs, and the importance of behavioural change. Dr Guiyi Li – Senior Manager, Secretariat of the Construction Industry Council (CIC). Dr Li outlined the CIC’s plans to develop a zero emission education centre in Kowloon, to be opened in 2012. He described the features and technologies that will be utilized to create a carbon neutral, and climate positive building. The project aims to promote the feasibility of low carbon technologies and their continual improvement, providing a platform for industry stakeholders to compare products and systems to nurture innovation, as well as advocating and promoting education on the practicality of zero carbon living and encouraging a change in lifestyle.
