Looking up a skyscraper For More Fairness in Height Rankings

The "building mass height" definition affects the order of older height rankings. Older definitions of the 'building height' produce counterintuitive rankings that do not take recent developments in construction and design into account, especially very tall spires and decorative features. The revised rules and rankings provide more acceptable and common-sense results.
