This session will include two presentations. The first presenter will be discussing the results of a case study involving the comparison of actual ventilation rates found in Minnesota bars and restaurants to ASHRAE 62.1 guideline criteria. Carbon dioxide tracer gas levels were measured to determine the effective ventilation rates in bars and restaurants in this state prior to implementation of a statewide smoking ban. 65 bars and restaurants were studied, and the results of this study are presented in this session. The 2nd presenter for this session will be discussing a case study involving a hybrid ventilation system applied to a super high-rise building in Tokyo, Japan, focusing on the indoor environment in the building and the effects of the system on the variation of thermal load.
