Projects aimed at reducing travel distances and thus increasing residential and employment density, accompanied by adequate mobility planning and transit supply, can be effective in decreasing the demand for transport as well as stimulating modal split toward less polluting modes. A number of empirical (mainly economic) studies confirm the positive effect of denser urban form on reducing travel distance per capita (e.g., Boamet and Sarmiento, 1999, Bento et al., As mentioned in the first section, building-related energy use accounts for approximately 24% of overall domestic energy demand, taking into account the building’s life cycle (construction, operation and demolition).
