In this scenario, the total social electricity consumption in 2020 and 2030 will reach 8300TWh and 10700TWh respectively 12 SESSION TITLE: Building, Eco-district and Demand Response Challenges

13 Distributed Generation. DG includes City CHP, roof-top PV and small wind In general, small hydropower, biomass, PV and natural gas generation will hold a promising future Year DG cap. (GW) % of total cap ~ ~ Major players By-product gas; heat; biomass Small hydro; Distributed PV; Distributed NG 13 SESSION TITLE: Building, Eco-district and Demand Response Challenges

14 Smart Grid and Smart City Smart grid implementation is to achieve sustainable, marketable, affordable, reliable and technological advanced electrical system Smart city is the integration of Internet of Things and other new generation of information technology and application. Its main role is to make city life more intelligent, efficient use of resources, increase energy saving, improve service delivery and quality of life, reduce cost, support innovation for low-carbon economy and innovative processes. People is the focus 14 SESSION TITLE: Building, Eco-district and Demand Response Challenges

15 Development of China's Smart City. N Since 2011, China's urbanization rate topped 50%, urban construction pattern need urgent transformation. The smart city is one of the three objectives of urban development in New town development plan In 2015, 95% of the national sub-provincial level cities, 76% of the city level and above, a total of about 500 cities under construction have proposed Smart City Currently, there are about 277 smart city pilot projects. The market size is estimated around 4 trillion yuan 15 SESSION TITLE: Building, Eco-district and Demand Response Challenges

16 Demonstration Projects. 16 SESSION TITLE: Building, Eco-district and Demand Response Challenges

17 China Green Building Development Till 31st December, 2013, the green building projects of the whole country is 1446, with a total construction area of m2 In 2013, the number of green building projects is 307, with a construction area of 24,370,000 m2. The percentage of one, two, three-star projects is 39.7%, 39.1% and 21.2% In geographical distribution, the top ten of green building projects are Jiangsu, Guangdong, Shandong, Shanghai, Hebei, Tianjin, Zhejiang, Hubei, Beijing and Fujian 17 SESSION TITLE: Building, Eco-district and Demand Response Challenges

18 Typical Green Buildings in China.. 18 SESSION TITLE: Building, Eco-district and Demand Response Challenges

19 Demonstration Project - Tianjin Eco-City On 18 November 2003, the framework on the development of an Eco-city in Tianjin of China was signed The Eco-city Master Plan encompasses aspects such as eco-economy, eco-society, ecoenvironment and eco-culture with consideration for sustainability The development of Eco-city targeted for completion in 10 years and the population will be 350, SESSION TITLE: Building, Eco-district and Demand Response Challenges
