2 Eco-city proposed and redefined by Richard Register (1987, 1993, 2006) self-reliant, minimize the demands on resources like energy and water and reduce waste no commonly agreed definition to date become an important issue and realized in practice in recent decades, currently prominent in policy discourses worldwide and research agendas in various disciplines (Caprotti, 2014; Hu, 2015) 174 Eco-City projects reported in 2011 in Asia (China, India, Japan, South Korea), Europe, America (North and South), Australia, New Zealand, Middle East and Africa (Joss et al., 2011) 4

3 Eco-cities in China China is in the lead in lots of ways. One thing that you can simply see is that China is trying to build an ecological city. You don't see the United States doing that. Register, 2011 in Scientific American 6

4 Ten eco-cities (low carbon cities) in 2011 (Hu et al., 2015) Sino-Singapore Sino-French Sino-Dutch 7

5 Study purpose Question: What place for numerical modelling in the fabric of ecocities in China? Which are the model currently used: which sectors? which models? In which phases (conception, construction, management)? For what targets? To what extent are the results considered in decision-making processes? What difficulties (default of models, data scarcity, knowledge insufficiency)? Further thought The replicability of these modelling practices? What are the common features, and what are different, and why What need for making them replicable to other (inter)national cases Who can we put around the table about modelling (academics, practitioners, tool-developers, residents, decision-makers...) What perspectives for models in building sustainable future cities? Study method: literature + interview 12

6 Tianjin Eco-City (Sino-Singapore) 45 km 34 km² residents expected 13

7 Tianjin Eco-City 2nd G-to-G eco-city project between Singapore and China designed to leverage Singapore expertise in top-down city planning, systematic management and water treatment technologies (Hu et al., 2015) pratical (pratique) replicable (reproductible) and scalable (extensible) started in 2008 and expected to be finished by 2020 (basic infrastructure finished in 2013) 14

8 Tianjin Eco-City Master plan (2008) by China Academy of Urban Planning and Design; Tianjin Institute of Urban Planning; and planning team from Singapore Key Performance Indicators (22 control, 4 guiding). Example: Per capita domestic water consumption < 120 l/d Carbon emission per unit GDP < 150 t/million $ 90% green trips Etc. 16

11 Fonctionnement du GT Modélisation et dynamiques urbaines Céline Bonhomme (LEESU)

12 Articulation du post-doc de Yinghao Li avec les activités du groupe Approche multidisciplinaire de Yinghao Li en lien avec les indicateurs de Tianjin éco-cité (bilan carbone, émissions dans l air et l eau, mobilité sur l éco-cité de Tianjin). Laboratoires intéressés par le suivi de son post-doc (réunions tous les 2 mois):cired, LEESU, LVMT, LATTS Mise en place de collaborations entre les laboratoires du groupe et les interlocuteurs de terrain sur l écocité de Tianjin (LVMT, LISA)

13 Historique des activités des post-docs avec le groupe 2 axes principaux pour le groupe Usages des modèles urbains pour l action publique (Lorenza Tomasoni puis Hadrien Commenges). Suivi: CEREA, LEESU, LVMT Modélisation intégrée urbaine (Julie Prud homme). Suivi: CIRED, LISA, LVMT Cas d études en Ile de France -> Souhait d une ouverture internationale Ouvrage collectif en préparation sur la modélisation urbaine (rôle de premier plan d Hadrien Commenges).
