"Buildings everywhere need to get off fossil fuels in order to help the world
avoid climate catastrophe.
Yet owners of large commercial buildings in New York City are especially
feeling the pressure: The groundbreaking Local Law 97 takes effect this year,
requiring buildings of more than 25,000 square feet to meet specific emissions
limits, which become more stringent in 2030, or face hefty fines.
One cutting-edge retrofit project is underway at the corner of Hudson and
Charlton streets in lower Manhattan.
The 17-story Art Deco office building, built in 1931, is ditching its
fossil-gas boiler for uber-efficient electric heat pumps that are both heaters
and air conditioners. They’re key components of a system that aims to heat and
cool the building more efficiently by capturing thermal energy that would
otherwise be wasted.
The state is backing the demonstration project, which could serve as a model to
decarbonize the more than 6,000 high-rises that punctuate New York City’s
skyline.
As part of the Empire Building Challenge, the New York State Energy Research
and Development Authority (NYSERDA) awarded $5 million to the 345 Hudson
project in 2022, which also has more than $30 million in private funding.
Project leader Benjamin Rodney estimates that once the project is complete in
2030, the building will use 25 percent less energy than a conventional design
and reduce greenhouse gas pollution by 70 percent relative to 2019 levels. As
the grid cleans up, he expects the figure to climb to 90 percent by 2035."
