Shiny Glass Skyscrapers Are a Hot Thing. Literally.

One thousand feet above city traffic, from her new 74th-floor apartment, Anastasia Zeeman has the kind of enchanting views that only floor-to-ceiling glass can offer. She looks out on a skyline and horizon where storms and sunsets play out like big-screen movies. But Malaysia’s tropical sun sometimes delivers what Ms. Zeeman calls a “wall of heat” radiating from her windows. More than any other form of architecture, glass skyscrapers testify to the human desire for sweeping views and a sense of rising above the fray. In some of the world’s fastest developing places — Dubai, Mumbai, Jakarta, Kuala Lumpur — they have become city-defining showpieces, signaling sophistication and rising financial clout. And yet glass tends to be ill-suited for keeping out the heat, and its overuse often makes buildings more energy intensive to cool. That’s fueling a debate about whether these symbols of modernity make sense in a world growing hotter because of climate change. Some argue that the ambition and innovation that spawned the high-rise era can help modern skyscrapers fend off rising temperatures while maintaining the million-dollar views. Others say the all-glass aesthetic is at odds with the environmental goal of reducing greenhouse-gas emissions. They say it is time to rethink city skylines.
