Ventilation strategies in healthcare facilities are mainly directed towards mechanical systems. Due to patients' preferences or the necessity of terminal reheat/recool, Air Handler Units often turned off windows opened when systems active. This leads poor IAQ, nosocomial infections, and energy loss. Besides, ventilation not typically intended optimize user satisfaction. Using field measurements 140 spaces, survey studies, statistical analysis, this study compares providing thermal comfort, Perceived Quality as an indicator 315 samples were collected for air velocity, temperature, relative humidity, PAQ, odor intensity, VOC concentrations. Lowest highest pollutant concentrations observed respectively with two open windows, one window, natural closed nonventilated spaces. There was no evidence effect on environmental parameters Users' comfort quality satisfaction guaranteed even rate, concentrations, within permissible range. Findings support efficient performance acceptable quality.
