To promote renewable energy in buildings and transfer of European advanced RES and energy efficient technologies and products into Chinese building sector, “Sino-EU Workshop on Renewable Energy Application for Cooling and Heating” was held on 18-19 February of 2009 in Hangzhou, which was organized by Zhejiang Energy Research Institute, in collaboration with the Solar Energy and Building Specialist Committee of China Renewable Energy Society organized.
The officials of the Ministry of S&T of China and Zhejiang Provincial Department of S&T as well as Secretary General of China Renewable Energy Society (CRES) presented at this Workshop, more than 70 attendants came from 52 institutions both in Europe and China, including GRETh in Franch, Federation of European Heating and Air-conditioning Associations, Asenal Research in Austria, EVE in Spain, IT Power in UK , Ove Arup & Partners Hong Kong Ltd., and Energy Research Institute of National Development and Reform Commission of China in Beijing, China National Engineering Research Centre for Human Settlements in Beijing, China Academy of Building Research in Beijing, Shanghai World Expo Land Holding Co. Ltd., Shanghai Jiao Tong University, Tsinghua University, University of Science and Technology Beijing, and others in 13 provinces and cities around China.
At the opening session, Mr. Zhaomin, Director of Zhejiang Energy Research Institute, firstly delivered warm welcome to all attendants. Mr. Zhangjian, on behalf of Ms. Luo Weihong who is Deputy Director-General of Zhejiang Provincial Department of S&T, wished this workshop to promote transfer of EU advanced RE technology into Chinese market, with the view of energy conservation and emission reduction. Mr. Li Baoshan, Secretary General of Chinese Renewable Energy Society said that renewable energy has been rapidly grown in recent years in China, and Chinese governments at central and provincial levels provide great support on RE, in terms of R&D and demo projects as well as incentive policies, he believed that best practices experience of renewable energy application in buildings in Europe will be helpful to China, and the workshop will act as a technology platform for further mutual exchange between China and Europe. Mr. Bernard Thonon, Project coordinator, introduced ASTECH project, and the significance of renewable energy application for heating and cooling to European energy safety and global climate change, he also stressed the key roles of technology support in application of renewable energy, together with incentive measures and regulatory mechanisms, i.e. “carrot and stick” policy. Finally, Mr. Yin Jun, Section Chief of Department of International Cooperation of the Ministry of S&T of China, reviewed the Sino-EU S&T cooperation in energy field in the past 20 years up, and reaffirmed that Chinese government attaches great importance to the renewable energy development, and it also does to cooperation with EU in RE field, and expressed the interest of Chinese side to cooperation with European side in various forms of technical exchange and R&D.
The workshop consisted of Session of Policy Study and International Cooperation and Technical Session of Energy in Building.
In the Session of Policy Study and International Cooperation, which was chaired by Mr. Zhong Jishou, Director of China National Engineering Research Center for Human settlements, Chinese and European speakers respectively outlined the situation of renewable energy development in China and Europe, particular on application for heating and cooling, and related legislation and incentive policies etc. At first, Mr. Ren Dongming, Deputy Director of Renewable Energy Center under Energy Research Institute of National Development and Reform Commission of China, introduced the background of China’s renewable energy strategy, Chinese renewable energy law and its detailed regulations, as well as latest status of wind power, biomass, solar thermal utilization and PV etc. in China. While Mr. Bernard Thonon briefed energy status in Europe, and specified the figure that energy in European buildings accounted for 38.7% of total one, he lead Chinese attendants to learn about EU three energy targets by 2020, i.e. 20% of reduction of energy consumption, 20% of RE in energy mix and 20% of increase of energy efficiency, and status of RE technologies for heating in European countries. Mr. Tang Shifang, General Manager of Shanghai Expo Land Holding Co.,Ltd, offer their practices on solar hot water system, heat pump and the roof-integrated PV system in Shanghai Expo Park. Mr. Thierry van Steenberghe, Head of RDT, Rehva, introduced the concept of low energy cooling in buildings and related technology as well as achievements made by EU-funded projects and IEA. And, Mr. Shen Fuxin, Secretary General of Zhejiang Solar Energy Industry Association, outlined current status of solar energy industry development in Zhejiang province of China. At the end of the session, discussions were focused on how to further promote renewable energy application in buildings through Sino-EU cooperation in terms of technology transfer, policy study etc.
The Technical Session of Energy in Buildings was divided into Part I (heat pump technology) and Part II (Solar-assisted cooling systems), which were respectively chaired by Mr. Bernard Thonon, and Mr. Andreas Zottl.
At beginning of this session, Mr. Zhong Jishou, Director of China National Engineering Research Centre for Human Settlements, presented the practices and achievements of scale-up application of renewable energy in buildings in China, in terms of standards, demonstration, scientific support and dissemination, and showed the perspectives of RES in buildings in China. Mr. Manificat, General Director of GREht, introduced the Institute of Solar Energy in French and its functions and performances on RES renovation of buildings.
Referred to the heat pump technology, Ms. Zou Yu, Deputy Director of Energy Saving and Environment Institute of China Academy of Building Research, described in details the development of ground source heat pump technology in China, including incentive policies, technical standards and pilot projects as well as problems exited and countermeasures. And then, Mr. Andreas ZOTTL from Arsenal, presented the status of heat pump technology and two demonstration projects in Austria, he stressed that both heat pump itself and system design are vital to the performance of heat pump heating systems. Mr. Iñigo ARRIZABALAGA from EVE in Spain specified steps of the geothermal system, from options selection and design and test etc., through a demonstration project in Spain.
In the second half of technical session, Mr. Bernard Thonon on behalf of Dr. Alexander Morgenstern in Fraunhofer ISE (Germany), presented the state-of-art of solar-assisted cooling systems and demonstration cases in Europe as well as perspectives in coming future. Besides, Mr. Dai Yanjun from Shanghai Jiao Tong University and Mr. Liu Shuanqiang from Tshinghua University respectively gave the presentations of “Solar Desiccant Dehumidification, Cooling and Heating” and “Liquid for Desiccant and Air-conditioning Application”. Finally, Mr. Barry Lau from ARUP introduced the district Energy Schemes in Mainland China and Hongkong.
To the end, Mr. Thonon and Mr. Zong made closing remarks, they did believe that this workshop offered an excellent opportunity for both Chinese and European attendants to mutually understand and exchange information, with focus on RE policies and development objectives by 2020 in China and EU, as well as targeted RE technologies in buildings, i.e. heat pump and solar assisted air conditioning etc., where is great potential market to transfer EU advanced technologies and product into China.
In the morning of February 19 of 2009, attendants visited the air-conditioning projects with lake source heat pump systems in Hangzhou World Leisure Expo Garden, which are equipped with 16 sets of lake source heat pump systems with cooling capacity of 5600kW, and investigated the performance and specification of these systems. In the afternoon, the attendants had another filed visit at the solar water heater manufacture in Zhejiang Meida Solar Energy Industrial Co. Ltd.
With efforts from both sides, the workshop was successful and fruitful. The attendants were satisfied with the academic presentation, filed visits and streamlined organization.
