Summary
Ventilation rates in buildings are generally determined by means of tracer-gas techniques that permit calculation of the number of air changes per hour occurring in a given area, or, alternatively, by measuring the actual air flow in the ventilation ducts. There are difficulties associated with both of these methods. In this study in a San Francisco office building, we used occupant-generated CO/sub 2/ as an indicator of the actual ventilation rate. Two techniques were employed, a decay method and an integral method and, in both cases, measurements were conducted simultaneously at several locations. The decay method compared favorably with the conventional measurement methods in both the all-outside-air and recirculation modes, whereas the integral method showed a considerable deviation from the other methods in the recirculation mode. Both techniques show promise of being suitable methods for measuring ventilation rate in commercial or institutional buildings.
