Abstract
The framework to estimate air-conditioning energy consumption reduction and resultant CO2 emissions reduction was constructed in this research, which can evaluate the effectiveness of alternative urban climate mitigation scenarios. The evaluation process embedded in this framework consists of regional environment GIS database, technology inventory, policy options and one dimensional urban canopy model which evaluate urban climate at neighborhood scale. The framework developed was applied to the coastal district of Kawasaki, Japan, for August 2006, to explore effective combinations of technologies and policies. Our findings suggested that about 1% of CO2 emissions that originates in air-conditioning energy consumption by fresh-air load be saved at maximum by greening building sites, introducing water retentive pavement and installing energy-saving technologies for buildings in an appropriate manner.
