Pulmonary edema occurs when the alveoli fill up with excess fluid seeped out of the blood vessels in the lung instead of air. This can cause problems with the exchange of gas (oxygen and carbon dioxide), resulting in breathing difficulty and poor oxygenation of blood.
Currently buildings are limited to a height of 200 meters and are subject to not contrasting the view of Mount Royal, the city's central green space, with the only exception being antennas and communication towers, that are allowed to reach 223 metres (732 ft) above mean sea level.
The Council of Tall Buildings and Urban Habitat calculates the heights of buildings by first allocating them to one of three categories: office buildings, residential buildings and hotels, and mixed-use buildings. The floor to floor height of an office building is 3.9 meters per story, or almost 13 feet. Residential buildings tend to have floor heights of about 3.1 meters, or 10 feet per story, and mixed-use edifices' floor heights are about 3.5 meters, or 11.5 feet per story.
