Current thermal comfort standards (ISO 7730, ASHRAE 55-81 ) are basedupon experimental studies carried out with persons maintained in their owngeographical and cultural settings, mainly European and North American.The opportunity was given us for measuring the climatic parameters andcollecting the associated thermal judgements expressed by persons living inIvory Coast (equatorial Africa), namely studentsin their class-rooms. Re-sults showed noteworthy discrepancies between predictions based on stan-dards and observations actually collected. Thus, application of the standardsto climatic situations such as those met in Ivory Coast would probably im-ply, for the persons involved, a permanent stay in derived climatized indoorsettings, i.e. an every day-life in conditions obviously different from theirusual natural and cultural environments. Since standards pretend to be con-sidered as universally valid decision criteria, it is concluded that someadjustments of the thermal comfort standards would appear appropriate.
