Leonardo Marques Monteiro - New Methods in Urban Simulation

  1. 1. Environmental Urban Design for Central Urban Areas in Sao Paulo, Brazil (ongoing project) “ New Methods in Urban Simulation” at ETH Zurich November 2008 Joana Carla Soares Goncalves, Denise Duarte, Leonardo Marques Monteiro (presenter) LABAUT/FAUUSP Laboratory of Environmental and Energy Studies Department of Technology The Faculty of Architecture and Urbanism of The University of Sao Paulo, Brazil
  2. 2. THE CONTEXT and the need for re-distribution and re-design of the city density Neighbourhoods to be densified in Sao Paulo city centre PROJECT AIMS creating sustainable urban spaces in the city centre of Sao Paulo <ul><li>Increase population density for urban regeneration within the limits of environmental criteria </li></ul><ul><li>Improve environmental quality of the built space </li></ul><ul><li>Develop a design methodology for environmental urban design </li></ul><ul><li>Achieve urban design proposals for socio-economic benefits </li></ul>
  3. 3. Sao Paulo: a city of contrasts and opportunities
  4. 4. DESIGN PRECEDENTS Barra Funda: The New Neighbourhood (2004)
  5. 5. AREAS OF INTERVENTION Luz and Barra Funda The two areas of intervention: Barra Funda (top) and Luz (bottom) - approximately 4 Km apart Consolidated urban area x Empty brown field
  6. 6. LUZ Consolidated area area of intervention = 12 hectares plot ratio = 0,81 population density = approximately 140 people/ha new density target = 1.000 people/hectare ( source : PMSP, 2000)
  7. 7. BARRA FUNDA Brownfield area of intervention = 72 hectare plot ratio = 0,65 population density = 21people/ha new density target = 1.000 people/hectare
  8. 8. <ul><li>density x environmental variables: </li></ul><ul><li> solar access and daylight availability </li></ul><ul><li> air quality (green areas and air flow) </li></ul><ul><li> water management (rain water collection/soil porosity) </li></ul><ul><li> energy (efficient consumption and generation) </li></ul>Design question what is environmental quality?
  9. 9. DESIGN PROCESS
  10. 10. LUZ URBAN FORM
  11. 11. SITE CONDITIONS AND OPPORTUNITIES
  12. 12. ENVIRONMENTAL ASSESSMENT Shading analysis – summer solstice shadow analysis summer solstice 9.00 15.00 9.00 15.00 Shading analysis – winter solstice

  15. 15. environment shadow analysis winter solstice SOLAR ACCESS AND DAYLIGHT AVAILABILITY
  16. 16. BUILDING FORM THE PERIMETER BLOCK
  17. 17. BARRA FUNDA SITE CONDITIONS AND OPPORTUNITIES
  18. 18. URBAN FORM The Perimeter Block
  19. 19. The Tower Block
  20. 20. THOUGHTS AND FINAL CONSIDERATIONS <ul><li>Density targets drive environmental performance in consolidated urban areas x environmental targets drive density in open areas (empty brownfields) </li></ul><ul><li>Need to prioritise environmental criteria </li></ul><ul><li>Be critical about the environmental assessments </li></ul><ul><li>Define local environmental performance criteria </li></ul><ul><li>Introduce the concept of the public and the open space and “urbanscape” early on </li></ul><ul><li>Approach the environment as a cultural force </li></ul>
  21. 21. FUTURE STEPS <ul><li>The Urban Age Project (Sao Paulo 2008) </li></ul><ul><li>(LUZ: Area of special public interest) </li></ul><ul><li>26 hectares </li></ul><ul><li>2.500 people/hectare </li></ul><ul><li>40% social housing + 60% middle class </li></ul><ul><li>Positive impact on public transportation </li></ul><ul><li>Energy generation: 70% of demand </li></ul><ul><li>Water harvesting: 70% of demand </li></ul><ul><li>Landscape: environmental and cultural force </li></ul><ul><li>Inviting outdoor spaces </li></ul><ul><li>Environmentally responsive architecture </li></ul><ul><li>Lively neighbourhood!!!!!!!!!!!!!!!!!! </li></ul>
  22. 22. NEW ENVIRONMENTAL CRITERIA the built form Urban noise Landscape Culture and environment “ Urbanscape” coherent to the local identity URBAN CRITERIA Air quality (pollution dispersion) Water management Energy Generation (water heating) Outdoor comfort Universal design for accessibility Solar access and Daylight availability Ground condition Pedestrians activities
