9.Summary of Research Results

  The population increase and concentration are generated mostly in the megalopolises of hot and humid Asia, and the increase rate of urbanization in hot and humid regions of Asia is expected to be exceptional even from a global viewpoint. Population increase and concentration in urban regions cause various environmental problems. On the scale of cities, on the one hand, they have generated environmental problems including heat island phenomena and air pollution, as well as an increase in the energy consumption associated with chaotic overpopulation, changes in land coverage conditions, etc. On the scale of buildings and rooms, on the other hand, direct application of European-style housing forms designed for cold climates and environmental control technologies, such as highly airtight building materials with a large heat capacity, to hot and humid regions has caused further deterioration of indoor environments. As a result, secondary environmental problems such as indoor air contamination and increases in the cooling load and energy consumption have been generated. It has thus become necessary for architects and city planners to take swift and multilateral measures to deal with these complex issues.
  As a specific method for the fields of architecture and city planning to respond to these problems of the living environment, this research proposes an environmental load-reducing porous-type housing model that effectively exploits the potential of outside environments by using voids.
  The porous-type housing model is found to be quite energy efficient and reduce environmental-load as compared with the ordinary-types of housing in Hanoi.
