Gas-to-Induction Stove Retrofits: Impacts on Indoor Air Quality, Energy Use and Satisfaction

There is great interest in the potential to improve indoor air quality (IAQ) through replacement of gas cooking ranges with induction-electric. This session will present insights from three studies that measured IAQ impacts of retrofits, with one also documenting challenges and other impacts of the retrofit, including installation costs, satisfaction, and electricity used after the retrofits. A randomized control trial in California’s San Joaquin Valley replaced gas stoves with induction electric in 91 low-income households with children with asthma. That study measured IAQ at baseline and after two 3-4 month study phases and asked about satisfaction with gas and electric cooking in all homes and measured cooking electricity use in 25 homes. A study in the Midwest conducted an intensive two-year study with IAQ monitoring pre/post in 10 homes. A third study in Washington DC, measured IAQ in two adjacent multifamily buildings with 41 units in the final dataset. In one building, tests were conducted twice before and after gas stoves were replaced with electric, and were compared to results from a second all-electric building.
