Ozone Depletion Factor Law and Legal Definition
According to 10 CFR 434.201 [Title 10 – Energy; Chapter II -- Department of Energy; Subchapter D -- Energy Conservation; Part 434 -- Energy Code for New Federal Commercial and Multi-Family High Rise Residential Buildings; Subpart B -- Definitions], the term ozone depletion factor means “a relative measure of the potency of chemicals in depleting stratospheric ozone. The ozone depletion factor potential depends upon the chlorine and the bromine content and atmospheric lifetime of the chemical. The depletion factor potential is normalized such that the factor for CFC-11 is set equal to unity and the factors for the other chemicals indicate their potential relative to CFC-11.”
