Up to 16% of fuel in New York City buildings is used to heat air lost through rooftop vents according to a new Urban Green Council report
This wastes 80,000 barrels of oil and $11 million across the city every year.
Vents built into elevator shafts leak enough warm air throughout winter to fill the Empire State Building 29,000 times over.
In Spending Through the Roof, the New York affiliate of the U.S. Green Building Council (USGBC) looks at why so much air is lost through these vents, offer ways to estimate the impact, and provide clear advice on how to close or reduce their size to save energy—up to 16% of heating fuel is spent on leaked air—and money.
