    The 2018 revision of this standard updated only a single section of the standard, specifically the estimation of CO2 generation rates from building occupants. The need for this revision was identified almost immediately after the 2012 version of the standard was published, with the subcommittee agreeing that after this section was updated the subcommittee would work to update the entire standard. Since 2012, a number of issues with the rest of the standard were identified that will be helpful in revising the full standard.
