Planning Strategies for Leading Energy Efficient and Sustainable City Development Case Study of Sino-Singapore Tianjin Eco-city

Bohai Rim has been marked as the most advanced economic development zones in northern China, which also brought along a series of issues such as high energy demand, resources depletion, environment pollution, etc. At this exact economic and ecological joint, China and Singapore governments proposed to develop an energy efficient, resources saving, environmental friendly and livable city over the 30sqkm abandoned saline-alkaline land, as a model that could be applied or duplicated for other cities development. This paper took Sino-Singapore Tianjin Eco-city as the case to study the planning strategies of sustainable and energy efficient city development. Renewable energy uses were introduced in various forms with full consideration on its respective economical sustainability to meet the 20% renewable energy usage Key Performance Indicators (KPI) of Eco-city's vision. All buildings are designed and built to comply with the Green Building Evaluation Standards (GBES) to save up to 70% of the energy demand of conventional build environment. By 2030, 90% of the city residents' daily trips will be green electrical private vehicles, public transport such as light rail transit (LRT), tram and electrical buses, cycling, walking. Smart grid, intelligent home energy management system, digitalized civic services enables a new lifestyle towards energy efficient and sustainable society.
