| Outline and Purpose of the Course |
Many buildings are accumulated in cities and majority of human activities are carried out inside of buildings. In this course, lectures will be given on; 1) The state of the art of global environmental impact by buildings and cities, 2) Environmental control methods concerning with reduction of global warming, 3) heat island mechanism and its reduction, 4) luminous environment control in urban area, 5) mitigation of urban disaster such as by fires and tsunami. |

| Course Goals |
The participants are to acquire knowledge on basic ideas of controlling environment in daily and emergent situations. B1:scientific ability to solve problems B4:understanding environmental aspect of architecture C1:ability to realize actual buildings |

| Schedule and Contents |
Global environmental problems and architecture (2 weeks) Environmental problems are identified in the hierarchy structure of global, semi-global, regional, urban, and architectural scales. The role of architecture in the age of sustainable development is discussed. Development of urban area and urban pollution (1 week) During the era of urban spreading, many urban pollution problems were raised. The history of reduction of urban pollution is looked back and identify that thermal pollution is the yet-to-be solved problem on urban environment and on impact on global environment. The urban thermal environment (4 weeks) The reasons for urban warming such as heat island phenomenon are explained. Special emphasis is made on the mechanism of heat island, the effect of urban coverage on heat balance of urban surfaces, heat accumulation to the deep ground area, multiple reflection of solar rays, emission of urban heat generated by human activities. Control of urban thermal environment (2 weeks) Various measures are discussed such as cross ventilation through urban area, areal and/or linear vegetation, high reflectance roofs, water mist, and heat recovery systems. Sunshine planning for buildings in urban area (2 weeks) The lectures cover effects of sunshine, calculation of sun position and sunlight illuminance, evaluation of sunshine using the sun shadow and sunlight diagrams, the building standard law on sun shadow regulations, and daylighting for a residential house. In addition, by overviewing a concept and technology of daylighting for buildings, new methods for daylight planning to achieve both energy saving and human comfort are discussed. City fire (3 weeks) Impacts of fires following earthquake and tsunami on urban environment are overviewed by introducing the causes of fire occurrences, the mechanism of fire spread, and the human behaviors in past large-scale fires. How fire risk in cities should be controlled is discussed. End-term examination and evaluation of achievements (1 week) Checking degree of understanding. |
