Gregory P. Mango \/ pool<\/p>\n<p>TENs are geothermal networks that capture, store and redirect heat, thereby cooling broiling-hot spaces such as the Chambers Street J\/Z stop \u2014 Mamdani said as he visibly sweat during a news conference in the decrepit station.<\/p>\n<p>\u201cAnyone who has stood on a subway platform in August knows that our stations do not just get hot \u2014 they turn into underground saunas,\u201d the perpetually besuited mayor said. <\/p>\n<p>\u201cIf you, like me, do not know what a summer suit is and choose instead to commute in a wool one, let me tell you, it is far from a therapeutic experience,\u201d he quipped.<\/p>\n<p>The \u201cthermal energy network feasibility study\u201d will explore harnessing the heat that builds up at the subway station over the summer to heat government buildings \u2014 including City Hall, the David Dinkins municipal building, Tweed Courthouse and Surrogate\u2019s Court \u2014 come the winter, Mamdani said.<\/p>\n<p>A contract to conduct a feasibility study first needs to be awarded by the fall, with an eye toward design work in early 2027, according to officials.<\/p>\n<p>The project would be the first TEN in a US transit system, officials said.<\/p>\n<p>The city\u2019s subways can turn into \u201cunderground saunas\u201d during the summer, Mamdani said.

Paul Martinka<\/p>\n<p>The project would include radiant cooling technology to absorb heat from the Brooklyn Bridge-City Hall platforms \u2014 and potentially those on Chambers Street as well \u2014 and transfer it through pipes to geothermal boreholes, officials said.<\/p>\n<p>Those boreholes will be drilled beneath an abandoned Chambers Street platform, an ideal location for testing the technology because it would disrupt passengers, the officials said.<\/p>\n<p>\u201cWe would capture heat in boreholes that will run 500 to 600 feet underground, and install a system of circulating pumps and pipes that will use the heat from below our city surface to warm the offices where our municipal workers are hard at work powering this incredible city,\u201d Mamdani said.<\/p>\n<p>The project would dovetail with an effort to rehab the infamously dilapidated Chambers Street subway station. Gregory P. Mango \/ pool<\/p>\n<p>The work at Chambers Street would dovetail with a project announced last week by Gov.
