  1. How to “green” large-scale urban design projectsTraining session World Urban Forum VRio de Janeiro, Tuesday March 23rd 2010

  2. Introduction to UrbEn group • Who we are? • Team of 8 urban planning professionals • From various countries • Representing several specialization areas • Integrated water resources management • Energy efficiency in built environment • Waste management • Urban regeneration • Urban agriculture • Nutrients • Others

  3. This course will cover: • Linkages between crucial environmental and social issues in different contexts and “green” building strategies and technologies in the building sector, and enhance participants’ awareness. • Tools that will facilitate the development of more natural resources and energy efficient as well as socially inclusive urban design models. • Challenges of a trans-disciplinary discussion between actors engaged in the design, decision-making, implementation and construction (e.g. developers, planners and law makers) of large-scale urban design projects • Experiences of the various types of actors and backgrounds at the training session

  4. Training session outline 9:15-9:40(25 mins.) Part 1: Introductory lecture • Discussion: Sharing experiences / case studies 9:40-10:20(40 mins.) Part 2: Exercise 1 Urban context questionnaire • WHOLE GROUP: Identifying ‘key areas of contention’ in Rio 10:20-11:40 (80 mins.) Part 3: Exercise 2 Urban design toolkit • SMALL GROUPS of 6-7 participants • Group presentations & Discussion

  5. Introductory lecture

  6. Problem context • Very rapid ongoing urban expansion in built-up areas in developing economies • Cities using more resources than available in the hinterlands • New urban developments often absorb most fertile land • Due to agricultural society legacy • Thus, ways of using natural resources such as land and water, and energy more efficiently, need to be integrated into new developments • New models of urban design are needed

  7. Large-scale urban developments • In rapidly transforming urban contexts, time and capacity resources may be limited • Therefore, developers keep implementing the same models which are not necessarily sustainable • Anonymous example from Beijing, China • Based on fixed idea of ‘modernity’

  8. Large-scale real-estate development • Example in Beijing, China • Predominantly high-rise and on urban periphery • Often use greenspaces and water although lack of resources • House up to 30,000 people but lack of services • Often lack of access by public transport • Not necessarily sustainable

  9. Many sustainable models already exist • New models for new cities • Modern architects like MVRDV or Foster & Partners • Examples: Masdar in Abu Dhabi, Tianjin Eco-City in China • Seldom address challenges of existing cities • As well as existing examples of more sustainable design and practice • For example Curitiba in Brazil, a well-known example • Eco-settlements in Europe • Level and tools for knowledge exchange on these solutions? • And many traditional urban design solutions • ‘Smart’ in dealing with climatic challenges • Use practical and low-tech solutions

  10. Facilitation of knowledge flow needed • But the flow of these solutions into the building sector is still limited • Existing standards and frameworks often address micro-scale green building standards • But not much yet at neighbourhood scale • LEED-ND (USA), certification starting from 2010 • DGNB (Germany) developing neighbourhood level indicators • Applicability of such frameworks to developing country contexts? • Tools for facilitating the creation of new widely applicable solutions are needed

  11. Our aim is: • To address challenges systematically • To tackle challenges at spatial scale at which cities are being constructed: • Large-scale real-estate developments: represent increasingly large segments of the city • City governments’ growing interest in better urban environment • Size of projects = High visibility of projects function as signs • A range of actors are involved in the urban design & decision-making process = a discussion platform • To develop tools to assist the urban design process and knowledge exchange

  12. Aim of this session • Introduction of set of tools as part of urban design process • Exercise using a 3 level approach: • Urban context questionnaire: assessment of the urban context • Urban design toolkit: a range of existing urban design solutions to support new model development • Discussion on implementation context of new urban design model • Collect feedback from you

  13. Part 2: Urban context questionnaire

  14. Based on existing frameworks • Questionnaire builds on: • UNDP/UNCHS/Wold Bank 1994: Urban Management Program:‘Rapid Urban Environmental Assessment’ • UNEP: Integrated Environmental Assessment • UN-HABITAT 2003: Housing situation and housing needs assessment • United Nations Statistics Division 2003: Social Indicators in the Urban Context: Urban Poverty and Health Study • UNDP 2008: Capacity Assessment (+ Support Tool) • UNECE 2009: Sustainable energy division: Action plan for energy efficient housing in the UNECE region

  15. Aim of the questionnaire • Tool to systematically provide a ‘macro’ overview of an existing urban context • Highlight key ‘areas of contention’ • Assess an urban context ‘neutrally’: • Without bias to finding certain problems • Questionnaire aims to capture all ‘flows’ into and out of a city • Can be used to assess any urban context in developing as well as developed economies • Not related to the decision-making process • Place different urban contexts into a comparative format • During urban design, quantitative/qualitative questionnaire data can be retrieved to guide design process and refine design

  16. Urban Context Questionnaire • How it works: • Quantitative and qualitative data collection • Expert weighting of each indicator • Scale 1-9: 1= least & 9= most important • Indication of key areas of contention by colour-coding • Who fills it in? • Independent consultant • Time estimate: 6-8 weeks • Depends on data availability

  17. 4-level Questionnaire Matrix • 7 key topic areas • People, Land, Water, Air, Energy, Waste, Nutrients 6 categories Topic-specificsub-topics Each sub-topic is defined by a set of indicators

  18. Summary matrix of the questionnaire

  19. Exercise 1 • Today, we don’t have time to fill in the whole questionnaire • Therefore, we will identify ‘key areas of contention’ in Rio using the matrix • Exercise with the whole group

  20. Part 3: Urban Design Toolkit

  21. Aim of the toolkit • To show neighbourhood scale solutions / case studies: • How communities working together and the proximity of buildings can aid sustainability • To provide a design support tool • For stakeholder group discussions • To formulate new urban design models • To visualize alternative future development scenarios • Target audience • Actors engaged in urban design, decision-making, implementation and construction • Compilation of sustainable urban design ‘good practices’ • Traditional and modern/visionary examples

  22. Urban Design Toolkit • Compilation of case studies are: • Documented individually • Using a comparative format • One A4 page per case study • Shows information on: Case study image Basic information Information by 7 topic areas

  23. Urban Design Toolkit • Case study selection is based on various existing ‘best practice’ compilation: • UN Habitat ‘Best practices’ • Aga Khan historic cities’ programme awards • European sustainable settlements: www.sustainable-settlements.eu • Global Ecovillage Network (GEN): http://www.ecovillage.org/ • LEED-ND pilot projects • Others • Today, we will apply the Urban Design Toolkit to a case study we have selected in Rio

  24. The case we will address today Rio case study:Barra de Tijuca suburb of Rio CityBarra in the 1970s: Empty land

  25. A guarded, gated community

  26. Barra de Tijuca: typical neighbourhood

  27. Urban Design Toolkit:Introduction to case studiesThese will be used to address the challenges identified through the Urban Context Questionnaire, using the case study in Rio to visualize possible solutions
