You don't feel anywhere near as much of that heat island effect at night, and even in hot Spanish summers, the interior of these houses stays pretty comfortable, with no AC needed.

      Using concrete for roads instead of asphalt would be the most obvious way to increase urban albedo. Problem is, concrete roads cost a lot more (but they also last a lot longer too). That's why highways are often built from concrete but small urban roads aren't - they aren't expected to have as much traffic. I suppose one has to look also at the relative energy and cost to create an asphalt road vs a concrete one.

      An alternative approach is to go for the 'shade' approach. Rather than paint things white, try to plant a metric buttload of trees over the city, such that most paved surfaces are shaded most of the time. Even if they are dark surfaces, if there is no sun hitting them, it's not a problem. Trees themselves have quite a low albedo of course, but they don't hold anywhere as much heat overnight as pavement.
