Heating, Insulation and Ventilation

Heating is the single largest use of energy in New York City buildings, with nearly 80% of all large multi- family buildings heated by steam distribution systems. Updating heating, insulation, and ventilation systems in buildings can result in huge energy savings, while reducing cost and increasing comfort. Nine out of the ten projects represented that upgraded these systems were large multifamily buildings. If all owners of large multifamily buildings in New York were to make similar upgrades as the projects submitted to Celebrate NYC, they could collectively save $145 million annually.
