New York Mayor Bill de Blasio has declared that skyscrapers made of glass and steel “have no place in our city or our Earth anymore.” He argued that their energy inefficient design contributes to global warming and insisted that his administration would restrict glassy high-rise developments in the city.

Glass has always been an unlikely material for large buildings, because of how difficult it becomes to control temperature and glare indoors. In fact, the use of fully glazed exteriors only became possible with advances in air conditioning technology and access to cheap and abundant energy, which came about in the mid-20th century. And studies suggest that on average, carbon emissions from air conditioned offices are 60% higher than those from offices with natural or mechanical ventilation.
