Hermann / MTA on FlickrMayor Zohran Mamdani and state officials this week announced plans to cool New York City subway platforms that turn into saunas during the summer. Kathy Hochul, and the Metropolitan Transportation Authority are teaming up to study thermal energy networks (TENs) at the Brooklyn Bridge-City Hall and Chamber Street complex, among the city’s hottest subway platforms. The TENs study will be part of a thorough renovation of the Chambers Street station, one of the city’s oldest. “For years, New Yorkers have suffered through sweltering summer heat on subway platforms, with seemingly no hope for a cooler ride in sight. This is what effective partnership between city and state government can yield—innovative solutions that have the potential to help millions of subway riders.”
