Climate change has become significant issue in every city. Intensive energy consumption and rapid population growth is the main driving force that leads to greenhouse gas emissions. Indirectly, consumption pattern and life style are also affecting the impact. Lack of understanding and awareness of local authorities and citizens makes the adverse impact to environment and human health. The study of effective measure which incorporates the factors contributing energy use and carbon emissions at local level context is fewer. Meanwhile, quantifying of those in urban area is not easy to carry out due to the difficulty in achieving city-scale data. This book presents the assessment of energy consumption and carbon emissions related to urban form by looking residential density in a developing city. A household survey was undertaken at high, medium, and low residential density areas. The proposed measures towards energy efficient and low carbon city are described. The results will give better perspectives and understanding to urban planners and decision makers dealing with energy use and carbon emissions in a developing city.
