In the climatically optimum city, the thermal comfort and even the health of some city-dwellers improves.
Less energy is needed for indoor temperature control.
Peak power demand and peak stormwater run-off are reduced, saving on the cost of city infrastructure. Glare and reflected heat from these pale surfaces can be reduced by shading from eaves, verandahs and from vegetation. Trees are Nature's own evaporative coolers - perfect for the dry climate, if water supply permits. Trees will also filter blowing dust from the air. In a warm humid climate , we need air movement to keep us comfortable.
