Properties are more costly in dense city center but the money saved from having to commute for work from a suburban area to downtown and back again make well worth it. The full spectrum of amenities, services and a walk able lifestyle are bonus of living in city center. And don't forget, rapidly growing population is also making traffic a bit more staggering than it has been in the past. Longer commuting time means more cash spent on fuel, automobile repairs and service, while the lost time between home and employment could be spent doing more productive things such as, spending quality time with family or putting extra hours at the office for a more paycheck. People often assume that high density discourages social interaction for social sustainability but that is not true. High-rise residents can run across their neighbors in corridors, elevators, in the car park and in the foyer, just as they do in low rise developments. In fact, in some ways they have more opportunitie...

As population density increase, the distance between people and their destinations decrease. Can reduces energy use, carbon emission, and waste in all sectors of city. The most important factor is automobile use, which is bad for the environment not only because they directly consume fuel and emit pollutants but because they facilitate the creation of far greater sources of energy and environmental damage. Automobile usage also encourage sprawling communities, over sized dwellings, inefficient commerce, and huge networks of redundant urban infrastructure. Density allows people walk from place to place due to proximity of services. Dense urban centers offer one of the few plausible templates for addressing one of the world’s most discouraging environmental illness, climate change. We need to find ways to reduce the size of our living spaces, and decrease the distance between ourselves and our destinations, and begin to step ourselves away from our near total dependence on automobil...

To achieve sustainable urban form, we need to know what it really is. We need to be clear and held common concept of “what is the sustainable city?” How it will function, how it will look like and how it will change overtime. There has been researches focused on compact versus dispersed settlement patterns and some indicated that compact urban forms offered the most sustainable future. But there is a lack of theory that helps us to evaluate whether a given urban form contributes to sustainability or to compare different forms according to their contribution to the sustainable development objectives and agenda. However, we also need to consider the complexities and impacts of a whole range of urban forms. The key elements of urban form such as density, compactness, mix of uses, housing type need to take into consideration when measuring sustainability. Prospects for the future are dire indeed, unless we act collectively to alter our energy-dependent lifestyles. Urgent changes are ...
