COLUMN IEQ APPLICATIONS
gas stoves. No reason exists to disbelieve the correlation,
but the causal nature is in doubt. A review of these
studies is beyond this column, but they certainly do not
show that any significant health impact difference exists
between gas and electric stoves when both have properly
operated range hoods in compliance with Standard
62.2-2022. Such a study would be quite valuable.
Conclusion
From its ventilation standards to the Epidemic Task
Force, ASHRAE has shown it is a leader in indoor air
quality. If gas stoves were really an inherent IAQ problem,
we would have seen it long ago. More likely the IAQ
problems seen are due to insufficient ventilation and/or
kitchen exhaust that can happen when energy efficiency
is pursued without adequate concern for IAQ or ventilation.
Such problems are what standards like Standard
62.2 were written to address-and no indication exists
that they have failed for gas stoves. No substantiated IAQ
reason exists to restrict gas stoves in Standard 62.2-compliant
homes.
If they are following industry and professional standards,
those who wish to have electric cooking can do so
in a safe, healthy and environmentally responsible manner.
The same, however, is true of gas cooking. While
differences may exist between gas and electric cooking-and
individuals may choose one over the other for
their own reasons-there is no significant technical or
environmental justification for a ban on gas (or electric
resistance) stoves. ASHRAE members should make it
clear that if one is meeting the intent of Standard 62.2,
one can still be cooking with gas.

Expanded and revised for 2022, both standards specify minimum
ventilation rates and IAQ requirements in order to minimize adverse
health effects for occupants. Learn more about the updates found
