Factors that influence distance to facilities in a sustainable efficient residential site design

Sustainability is a universal topic which has multidimensional effect on the environment and human life. Urban areas consume 75% of energy and produce the most greenhouse gases and pollution. The sustainability in urban built environment via improving efficiency in designing residential site and neighborhood, supports energy saving and pollution reduction. This paper tries to focus on distance to facilities to promote walkability in neighborhoods as the front line of sustainable movement in urban area. The study area is Subang Jaya Township in Kuala Lumpur, Malaysia with 155 neighborhoods. An empirical analysis was done to determine the factors that influence distance to facilities and daily necessary services in residential sites which support the increase of walkability and reduce car use and time used for accessibility to these services. The result shows density, land diversity, non residential land use, and employment influence the distance to facilities.
