Weatherization technologies include a wide range of energy efficiency measures for retrofitting homes and apartment buildings. Weatherization service providers choose the best package of efficiency measures for each home based on an energy audit of the home.

Weatherization measures reduce national energy demand by the equivalent of 18 million barrels of oil per year.

Weatherization saves an average of 32% in gas space heating. This comprises a total fuel consumption reduction of 23%. Net savings for each home weatherized average 30.5 MBtu/year.

Reducing energy demand decreases the environmental impacts of energy production. Weatherization mitigates approximately 1.61 metric tons of carbon dioxide per year in a home heated primarily with natural gas and even more for homes heated with fuel oil. Weatherization also reduces emissions of methane and nitrous oxide.

Weatherization creates non-energy benefits as well, including increased property value, reduced incidence of fire, reduced utility arrearages and bad debt, federal taxes generated from employment, income generated from indirect employment, avoided costs of unemployment benefits, and reduced pollution.

Additional benefits that are more difficult to quantify include improved health and safety conditions, increased comfort for occupants, a reduction in homelessness and mobility, and extended lifetime of affordable housing.

We have a list of State, County and Local level programs that offer weatherization related services for existing structures.
