New buildings will need alternative heating by as early as 2024. Learn more about the new law.
In May 2021, we reported on a new bill that would potentially limit gas heat in NYC. We can now say, as of December 2021, that this bill has been signed into law.
Local Law 154 of 2021 is the first of its kind for a large cold-weather city, seeking to switch from fossil fuel to electric heating by prohibiting the combustion of substances that emit a certain level of carbon dioxide in new buildings.
According to Bill de Blasio, the hope is, “If the largest city in America can take this critical step to ban gas use, any city can do the same!”
It should be noted that, while the original bill prohibited the combustion of any substance that emitted more than 50 million British Thermal Units (BTUs) of carbon dioxide, the law has been amended to be even more strict, capping the limit at 25 million BTUs. This rules out natural gas heating.
These emissions limits for new buildings will be required by early 2024, focusing on lower-rise buildings. This will build up to fully electric new construction for buildings of all sizes by mid-2027.
New buildings that do not comply will be denied permits and approvals for construction documents. This also covers gut renovations that meet the DOB threshold for major alterations.
In the meantime, the law also sanctions studies into alternative forms of heating, as well as the strength of the electrical power grid to handle the shift. Findings from these studies are set to release by mid-2023, which may influence the law and its enforcement going forward.
Potential exemptions for certain uses include:
The law will also delay requirements for hot water systems and buildings with over 50% affordable housing units by 6 months-2 years, depending on the size of the building.
Here is the full timeline for compliance deadlines:
The shift away from gas heat under LL154 will be an interesting challenge for the construction industry going forward.
However, it will also likely make it easier for larger buildings to meet their carbon emissions goals, and will produce better air quality inside and out, improving the overall health of citizens. Based on research by the Rocky Mountain Institute, the law will prevent 2.1 million tons of carbon emissions by 2040.
