The aim of the research was to find out the indoor climate conditions in Finnish commercial kitchens by measurements and inquiries. Twelve kitchens were selected from the Helsinki metropolitan area. The measurements concentrated on thermal conditions. On the average thermal conditions in measured kitchens are not fully satisfactory and they varied considerably between the kitchens. Thermal conditions within kitchens varied also depending on the workplace. Heat stress harmful to health was only found in two kitchens. According to measurements, ventilation rates in commercial kitchens should always be based on the loads caused by the cooking equipment. The research pointed out that in addition to the air flows the supply air temperature also has a direct influence to the temperature of the indoor air in the workplace. To guarantee acceptable thermal conditions the air flow rates and the temperature of the supply air must be controlled.
