Dissertation The effect of urban spatial and temporal development on the relationships between urban form, energy use, and CO2 emission.
都市發展時空變遷對都市形態能源使用與CO2 排放間之關聯影響
Abstract My research topic is “The effect of urban spatial and temporal development on the relationships between urban form, energy use, and CO2 emission”, focusing on sub-city scale of Taipei City. From the previous study on downscaling analysis of CO2 emission in Taipei City, we counted out the relationships between CO2 emissions and urban land use, and CO2 emissions increased as cities were expanding and becoming more densely populated.

We also found out that the administrative districts with same intensity of land use do not necessarily have the same CO2 emissions. The CO2 emission within the city were also affected by other urban form factors such as street density, land use mix, open space ratio, etc.

The intent of my study is to focus on the block scale to compare the relationships between their urban form and energy consumption and CO2 emissions. In addition, what are the underlying drivers (cultural, history, and spatial planning, etc._ which affected the urban for of different administrative districts within the city? )
Taipei city was developed from west to east and there are clear distinction on the street layout, road density, land use mix, building height, and open space ratio. There are 345 village districts in Taipei, which I will use as the research unit to analyze their urban form and collect energy consumption data to analyze the relationships between urban form and CO2 emission. In addition, the emergy stored in the building will also be analyzed to explore the relationships between embodied energy of building and energy consumption on the scale of street blocks.

In summary, the objectives of my research are as follows:
The relationship between urban form, emergy, and energy consumption within the city of Taipei.
The influence of underlying drivers (e.g. urban planning, historical development) on urban form.
How do these underling drivers contribute to today’s energy consumption and CO2 emissions?
