  2. 11. Energy analysis for sustainable mega-cities

    Author : Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.
