Biodiversity and natural areas

In as early as 2008, Sino-Singapore Tianjin Eco-City made a plan for biodiversity based on the basic goal of 'highlighting the protection and restoration of original ecology and building the natural ecosystem with reasonable ecological structure, complete service function and quality environmental quality.'

(1)Combine environmental restoration and landscape constructionto establish the plant communities dominated by local adaptable plants with a local plant index of no lower than 0.7.

(2)Restore and construct two bird habitats (Parrot Cay and Egret Cay) and the ecological environment succession area in Yongding island to protect the living environment of the local biotic population to the most extent.

Tianjin Eco-City investigated ecological resources in 2013, and the results show that the city has a total of 469 animal and plant varieties, including 332 animal varieties and 137 plant varieties.

Climate adaptation, resources conservation, GHG emissions

The Eco-City formulates the index of 100% green buildings, that is, all buildings must be green buildings in all these 10 years of construction. Formulate indexes for indoor noise, lighting and heat and humidity comfort in terms of indoor environment of building noise, light and heat, so as to improve the comfort of buildings; optimize resource consumption, follow the principle of 'Take passive as priority, active as auxiliary and renewable energy as supplement' at design stage, take energy consumption quota as constraint and optimize design through integration to avoid technology accumulation; optimize design through building structure, select green building materials and adopt new structural system and prefabricated industrialization to save building materials for green buildings; formulate and issue the Tentative Standard for Energy Consumption Baseline in Tianjin Eco-Cityby decomposing indicators suh as total urban carbon emission and renewable energy utilization, which becomes China's first quantitative energy consumption standard for green buildings so that corresponding techbcal system can be adpoted based on actual energy consumption level.

Energy sobriety

Energy is the driving force for the development of a city. In the face of the increasingly severe energy crisis, the Eco-City promotes energy conservation and emission reduction in an all-round way, actively develops and utilizes new energy and optimizes energy structure. It has installed solar water heating facilities for all residential buildings and achieved GSHP cooling and heating in public buildings and the industrial park. The buildings that apply various new energy cover a total area of 2.13 million m2, which can save 10,500 tons of standard coal and reduce 25,500 tons of CO2 emissions, and has initially formed a new energy utilization system with geothermal energy, solar energy and wind energy as the main energy.

Energy mix

Geothermal energy utilization: Geothermal resources are abundant in the area. By using GSHP, deep geothermal heat pump and other heat pump technology, all kinds of geothermal resources are fully utilized and widely used in building heating and cooling.
