Speech / Presentation
As global cities have embraced sustainable urban design and entrepreneurial, their strategies can serve as a source of inspiration and new knowledge to U.S. cities and beyond. By pairing best practices from international metros with their U.S. counterparts, the Sam Fox School of Design & Visual Arts at the Washington University in St. Louis has developed a series of case studies that examine the urgent challenges of an increasingly urbanized planet, focusing on the development of sustainable products, services, technology, and land use patterns following the economic recession.
On February 21, the Metropolitan Policy Program at Brooking and the Sam Fox School’s Master of Urban Design Program hosted an all-day forum which explored the intersection between sustainable urban design and economic growth while discussing the implications for design and practice. The event also highlighted policies that have enabled individual cities to become successful models of sustainability and examined specific design and policy issues through the lenses of economy, government, climate and social systems.
Mark Wrighton, chancellor of the Washington University in St. Louis, welcomed the forum participants and audience members, followed by a presentation from Ricky Burdett, professor of urban studies at the London School of Economics and Political Science. Panel discussions covered transportation; environmental and building technologies; and adaptation and renewal. The program closed with a presentation from Mohsen Mostafavi, dean and the Alexander and Victoria Wiley professor of design at Harvard University’s Graduate School of Design, followed by a reception and respondent discussion.

how to better address housing needs.
The world witnessed an exponential growth in demand for housing in the post-World War II era. This resulted from rapid population growth and urbanization, and the need to rebuild a large portion of the housing stock affected by the war in many countries. To achieve scale and speed, mass housing was the preferred option in the decades of the 1950 to the 1970s. Mass public or social housing is a housing development that is publicly funded and administered usually for low-income families. Over time, in some countries, the ownership of this housing stock has been given to residents. Mass housing has been produced in many configurations including low rise, single dwelling units but more often multi story walk-ups or high rise apartment blocks. Housing units are laid out in clusters around open spaces or in parallel rows as well as other configuration. In rare cases globally, public housing is integrated within the city urban texture.
While mass housing is still policy in some countries today, the majority built earlier are at a historic milestone. The buildings are aging, in many cases in need of repair that is not being addressed due to limited resources. Frequently, this housing stock is now occupied by lo
In summary, mass, public or social housing estates today face some or all of the following challenges:
• Location is usually in isolated zones of housing in the periphery or away from city centers. In some cases, older housing is now located centrally and the land value is underutilized;
• Monolithic housing use following master plan zoning or planned in isolation as standalone estates;
• Residents commute to access daily needs; workplace, services, shopping, recreation, etc…;
• Urban sprawl, large environmental footprints, high carbon emissions, etc…;
• Inflexible prefabricated housing results do not respond to the changing needs of families sizes;
• Mass housing open spaces mostly neglected, underutilized and unsafe in some cases;
• Ownership when awarded to resident occupants results in poor management and maintenance;
• Aging housing stock dilapidation due to lack of maintenance and repair (aging water pipes, etc.);
• Aging inhabitants need more accessibility, have low incomes to address maintenance;
• Sometimes, mass housing attracts immigrants resulting in social segregation (ghettoization);
• Social ills such as drug trafficking, gangs, etc… tend to move into mass housing complexes;
• Environmentally, low-cost construction usually entails high heating/cooling energy consumption;
• Lack of tenure of occupants contributes to insecurity and a poor sense of belonging/responsibility;
• Lack of financial resources and poor maintenance have led to deteriorated living conditions;
Overall, the majority of mass housing in today's world does not conform to the norms of sustainable urban ism. Given the magnitude of the existing characteristics above and the continuation of mass housing trends in some places today, there is an urgent need to address these challenges. Lessons learn will also guide policy makers and decision makers on how to better address housing needs.
