Synopsis: First, we investigated the optimal tracer gas supply method in our multi-zonal ventilation measurement system through measurements and computational simulations. Second, we investigated a simple measurement method involving generation of carbon dioxide gas by solid alcohol combustion through measurements and computational simulations. In the first investigation, we found that a sufficiently long decay time of gas concentration was necessary between gas supply periods. In the second
