This criterion evaluates the building‘s space consumption. Its aim is to reduce the space consumed by settlement and highway infrastructure and to prevent further greenfield sprawl. This is aimed at reducing the proportion of the earth‘s surfaces that is sealed and made impermeable, thereby preventing rainwater infiltration (e.g. through asphalt and concrete surfacing). Existing sealed areas should be replaced by permeable surfacing inasmuch as possible. Maximum use should be made of sites already prepared for development
