I live in Columbus, Ohio, U.S. and when you look at our skyline the tallest buildings all seem to be the same height and a lot of locals believe we have a height limit, when in fact we do not. There is no height limit (within the CBD) here according to official city documents. Most new development is more low to mid rise which is allowing for more sunlight in areas vs areas that are skyscraper canyons. I do think there should be a healthy balance of height and setbacks. I believe Stockhom has an ordinance in effect in the CBD that reads along the lines of a certain percentage of daylight must be allowed due to their northern latitude and short winter days.
