Questionnaire surveys and field measurements regarding indoor thermal environment and energy consumption were implemented to clarify the following two issues; one is optimum control condition for natural ventilation to make occupants comfortable; the other is impact on energy conservation caused by employing the optimum control condition. The following results were obtained from this survey. 1. Ratio of the dissatisfied occupants is low where the range of indoor air temperature is 23.0℃DB to 28.5℃DB 2. The boundary of air flow velocity that makes occupants uncomfortable is 0.7m/s to 0.9m/s 3. The actual annual cooling load in the second year and the third year decreases 30% and 40% respectively than the first year, where the optimum control condition is employed. This result indicates that the control strategy is significant for the hybrid ventilation system. 4. According to statistical analysis regarding daily actual cooling load, the efficiency of energy conservation of this system is approximately 30%
