Ecocitynotes.com: Critical Analysis of Eco-Cities in China
All but 2 of China's 278 cities with municipal status have proposed low-carbon or eco-city targets, and over half have already begun construction to achieve these goals. However, the term "eco-city" is not clearly defined in China, and it is uncertain how many of these projects are living up to their hype. Eco-City Notes, is an online multimedia web platform that aims to provide a unique perspective on eco-city development on the ground in China. Our interdisciplinary analysis draws from the fields of architecture, international development, environmentalism, anthropology, and engineering to understand the impact of the explosive growth and development of eco-cities in China. This presentation highlights our latest research on the complex and evolving eco-city concept in China.

2 Poor Indicators ( 绿化率 )
1) Urban public green space per capita >12 m2
2) Forestation coverage in built-up area > 45%
Tianjin: Decreased Density &Landscape not adapted to Climate
Qingdao: Too many trees!
Conclusion
Indicators must be tailored to a city’s state of industrialization and economic structure
Indicators have both good and bad impacts Definitions must be clear and measureable More useful as evaluative and comparative
metrics than design blueprints
DIRECTING THE DEMOGRAPHIC OF THE SINO-SINGAPORE TIANJINECO-CITY (SSTEC)
Cecilia Springer Fulbright Research Scholar, Nankai University
SSTEC: Background and Basic Facts•Development type: Local eco-city program ( 项目 ) with international collaboration•Estimated construction duration: 2008-2020 •Projected population: 350,000•Projected total area: 30 km2
•Location: 40 km east of Tianjin city center
SSTEC Key Performance Indicators
Qualitative Indicators

Regional Coordination
KPI Area KPI
Coordinated Natural Ecology
Ecological health and safety, green consumption, low carbon operation
Sales Pitches: Expanding the Green Lifestyle Concept
“ 像垃圾车,像回收车,不会进入咱们的社区,像蟑螂、老鼠什么的,都会有力地减少。这个是对生态比较帮助一些。” (“Garbage trucks, recycling trucks won’t need to enter our community, cockroaches, mice, and so on will be fully eliminated. This helps out the ecology. ”)
“ 在中国别的小区不会派追求绿化。这边的话,就必须得达到一个绿化的保证,有舒适度的”
(“Other communities in China wouldn’t emphasize this green space. Here, green space security must be achieved, it’s a level of comfort”)
Public housing: ~50 applicants for public housing lottery system Eco-City workers Displaced former residents
Laborers
Conclusions
Residential behavior determines the outcomes of several key indicators Implications for liveability of the Eco-City City diversity Will residents adhere to green standards?
Indicators will be assessed in 2013
URBAN FORM AND THE ENVIRONMENT: HOW CHINA’S ECO-CITIES STACK UP
MPA Candidate, International Development, Tsinghua UniversityGavin Lohry
What Urban Form has the least Inherent impact on the Environment?
• As Countries develop building and transportation emission become more important (larger percent of overall emissions)
• Hong Kong’s per capita level of building and transportation emissions are lower than major Chinese cities and just above the Chinese National
• What does Hong Kong do right?
Density is Important (What do we know about Density)
Reduces Transport Emissions Makes public transport more cost effective and convenient Increased number of services within walking/biking distance Makes driving less convenient and more expensive
Building Emissions Decreases building energy use through shared walls Reduces floor space and increases communal space
Other Effects Increases infrastructure efficiencies and service efficiencies Reduces the total amount of land used (more land for farms & forests)
Negative Effects Pollution is concentrated Heat Island effect, Peak Flow Volume increase, etc.
