Is it time to ban all-glass skyscrapers?

“If you’re building a greenhouse in a climate emergency, it’s a pretty odd thing to do to say the least,” said Simon Sturgis, an adviser to the government and the Greater London Authority, as well as chairman of the Royal Institute of British Architects sustainability group. “If you’re using standard glass facades you need a lot of energy to cool them down, and using a lot of energy equates to a lot of carbon emissions.”

As the global community continues to mobilize against the rising threat of climate collapse, cities and other entities are moving toward banning or limiting the future development of all-glass skyscrapers due to the buildings' high energy demands, according to a report in The Guardian. 

For decades, designers have relied on technological approaches like double- and triple-glazing facade units to maximize the energy performance of these designs, but as the limited lifespan of these systems comes under question, it has become clear that more drastic efforts are needed. 

Simon Sturgis, chairman of the Royal Institute of British Architects sustainability group, told The Guardian, “To mitigate the amount of energy used to cool these buildings, you have to produce a really complicated façade, which is usually triple glazed.” 

Sturgis added, “But double glazed units and laminated glass don’t last very long – 40 years or so. So you have to replace your facade every 40 years, that’s also not...
