According to data from the American FactFinder, the total number of housing units in New York City is estimated to be close to 3.5 million and 42%, almost half of these residential units, are located in buildings that were built in 1939 or earlier. Furthermore, more than half of the pre-1940 historic buildings are one or two family type houses. The Greening NYC’s historic buildings manual by the Municipal Art Society of New York (MAS) stated in their report that solid masonry walls such as layered brick walls in historic buildings ‘’were rarely insulated.’’ At the time, insulation was not required in building envelopes.

The Urban Green Council examined 2010 building types and their energy characteristic and reported that one or two family house types have higher heating and hot water loads than other residential buildings therefore, their energy bill is higher than homeowners who live in multifamily buildings. When we look at the total number of renters and homeowners in NYC, it shows that one third of the occupants own their homes and more than half of these homeowners live in one or two family buildings in NYC.
Heating is the biggest energy consumer in NYC, which makes energy efficiency programs important for the city to reduce its greenhouse gas emissions. Having insulation in building envelopes helps homeowners reduce their energy bills. However, homeowners need to be aware of certified foam materials and their potential health and environmental concerns.
