From the Wall Street Journal:
The skyline of New York is dotted with new glass condominium towers featuring some of the most expensive and sought-after apartments in the city.
But a new study is warning that there could be a price to pay for the grand views: Some high-rise apartments could become as overheated as a hot yoga studio in a prolonged summertime blackout, similar in duration to the one that followed superstorm Sandy.
In the winter, the study found that in a prolonged cold wave interior temperatures would plummet in glass towers during a blackout to a low of 35 degrees over seven days, but would fall even more in single-family homes and older brick apartment towers built with little insulation.
The study is part of a campaign by the Urban Green Council, a building industry group that worked on post-Sandy planning, to push New York developers to meet higher performance standards in the future. The council has called the glass-walled construction "a major step backward" environmentally; instead, it favors less exposed glass in new towers as well as expensive triple-pane glass and other improvements.
