A small percentage of building occupants report chronic thermal discomfort.

Offering personal heating/cooling devices is the best strategy to address the problem of chronic thermal discomfort among a small percentage of building occupants. This strategy allows occupants to adjust their local thermal environment according to their individual preferences and needs, which can improve their satisfaction and comfort. Personal heating/cooling devices can include fans, heaters, foot warmers, radiant panels, or under-desk air terminals. The other options either do not address the individual differences in thermal comfort or may worsen the problem by creating uniform and inflexible thermal conditions.
